Ultimate FAQ

Proper surface preparation is crucial for a successful Rust Bullet application. Follow these steps to ensure your surface is ready:

Clean the Surface

• • Remove Loose Material: Use a wire brush, scraper, sandpaper or media blast to remove any loose rust, scale, paint, or other debris.

• Degrease: Clean the surface with a degreaser to remove oil, grease, and other contaminants. Rust Bullet Metal Blast is great option as a cleaner and conditioner for your metal surface. You can also use a mixture of gentle detergent, such as dish soap, and water. Rinse thoroughly with clean water and allow it to dry completely.

Surface Profile

• • Smooth Surfaces: For smooth, non-porous surfaces (like polished metal), create a profile for better adhesion. Use 80-100 grit sandpaper or a similar abrasive to scuff the surface. Metal Blast will not only clean, but also etch your surface, eliminating the need for sanding.

• Rusty or Pitted Surfaces: Heavily rusted or pitted surfaces should be cleaned more aggressively to remove all loose material. However, Rust Bullet can be applied directly over rust, so removing all rust is not necessary.

Remove Dust

• Dust Removal: After cleaning and profiling, remove all dust and debris using a vacuum, tack cloth, or compressed air.

Dry the Surface

• Ensure Dryness: The surface must be completely dry before application. Any moisture can affect the adhesion and performance of Rust Bullet.

Masking

• Protect Adjacent Areas: Use painters tape and plastic sheeting to mask off areas that should not be coated.

Application Tips

• • Stir Thoroughly: Stir Rust Bullet thoroughly by hand until homogenous (approx. 3 minutes) before use. Do not shake and do not use electric or mechanical means to stir.

• • Apply Evenly: Use a brush, roller, or spray gun to apply Rust Bullet in thin, even coats. Overapplying can lead to adhesion failure and diminished product performance.

• • Multiple Coats: Apply multiple thin coats rather than one thick coat for better protection. Rust Bullet requires a minimum 2 coat application, additional coats should be applied to achieve the appropriate DFT (dry film thickness) for your application.

• • Drying Time: Allow adequate drying time between coats, typically two to six (2-6) hours, depending on humidity and temperature. If more than 12 hours have lapse since you last coat, you will need to allow 24 hours to cure and then lightly scuff the surface for adhesion of additional coats.

• View “General tips for a successful Rust Bullet project” for more useful tips and advise on your Rust Bullet application.

By following these steps, you ensure the surface is well-prepared for a durable and effective Rust Bullet application. Please refer to Rust Bullet’s application and technical documents for additional details.

If humidity is too high (80% +), it will adversely affect the curing and adhesion process. A couple of things can be done to minimize these effects. One is to provide air circulation or an air flow that vents the air away from the coated surface. This may assist in reducing the humidity but may also circulate particles and debris that may become embedded in the wet paint. Secondly, apply Rust Bullet with a brush. A brush application tends to trap less air and moisture and is therefore the best application method in a high humidity zone. Apply additional, thinner coats rather than fewer, thicker coats. This will help eliminate the formation of bubbles or blisters on the coating surface which can occur if the solvents cannot be expelled. The formation of humidity bubbles or blisters can result in poor adhesion, which in turn, may need re-sanding and a touch up.

Rust Bullet Rapid Fire Accelerator was designed to be added to all Rust Bullet coatings to decrease the normal recoat time of two to six hours to approximately 30 – 40 minutes per coat. Rapid Fire makes it possible to apply multiple coats of Rust Bullet in a single day and reduces project completion time by as much as 80%. Rust Bullet Rapid Fire Accelerator is designed for spray applications. A Rust Bullet coating accelerated with Rapid Fire can be applied with either an HVLP Spray System or an Airless Spray System.

IMPORTANT: Rapid Fire is to be added to the Rust Bullet coating at the job site; it cannot be added until you are ready for application. As soon as Rapid Fire has been added, the curing process begins. Pot life is approximately four to six hours. Only mix Rapid Fire Accelerator into the quantity of Rust Bullet that will be used within a four-to-six-hour period.

No. Rust Bullet products do not contain lead, zinc, chromates, acids, or heavy metals.

The most accurate way to measure dry film thickness (DFT) is to use a DFT gauge. Apply an appropriate number of coats to achieve the desired DFT for the appropriate protection for your project. Immediately after application, measure the wet film thickness (WFT) with a WFT gauge to ensure it falls within the target range, which can be converted to DFT using the formula: WFT=DFT×(100/Solids Content). Rust Bullet coatings are 70% solids by volume, so WTF=DFT×1.43. After the coating has dried, use a DFT gauge to measure the thickness at multiple points across the surface to confirm uniform coverage and adherence to the specified DFT.

Theoretical coverage does not consider transfer efficiency which will vary dependent upon application equipment, applicator, and atmospheric conditions during application. The number of coats needed to achieve the appropriate DFT will depend on the chosen method of application: brush, roller, HVLP Spray System or Airless Spray System.

The higher the mil measurement of Rust Bullet’s dry film thickness (DFT), the greater the protection provided. Generally residential or lightly used and low wear and tear applications require a minimum DFT of 6 mils. Industrial or commercial type projects where there is higher traffic and wear and tear, require a minimum DFT of 12 mils.

However, many variables should be considered when determining the desired DFT for any project. Some of these variables to consider are the existing condition of the surface being coated and the surface’s exposure to:
• Moisture
• Harsh chemicals
• Abrasive objects
• The damaging effects the surface must endure from environmental conditions and exposures.

If you need help in determining the appropriate DFT for your application, you can Contact Us for assistance.

Dry Film Thickness (DFT) is the thickness of a coating when dry, expressed in mils. One mil is equal to one thousandth of an inch. 1 mil = .001 inch (1/1000). For comparison purposes, the thickness of one sheet of standard paper is approximately 3-4 mils in thickness. Rust Bullet should be applied in thin, even coats. Each coat should be approximately 3-4 mils or one sheet of paper, and at max no more than 6 mils to prevent any coating failure.

Please see attached video for demonstration.

When working with Rust Bullet coatings, it’s essential to use appropriate personal protective equipment (PPE), including a proper respirator. Here’s the recommended type of respirator and additional safety gear you should consider:

Respirator Type

• • Organic Vapor Respirator: It is recommended to use a respirator with cartridges specifically designed for organic vapors. These respirators can effectively filter out solvent vapors that are emitted from Rust Bullet during application.

• Half-face or Full-face Respirator: A half-face respirator that covers the nose and mouth may suffice for shorter exposure periods or less intensive use. For longer durations or in enclosed spaces, a full-face respirator provides additional protection by also covering your eyes.

Additional Safety Gear

• • Gloves: Use nitrile gloves to protect your hands from the chemicals in Rust Bullet. Avoid latex as it may not provide adequate chemical resistance.
  • Protective Clothing: Wear long sleeves, long pants, and closed-toe shoes to prevent skin contact with the coating. Consider coveralls if extensive exposure is expected.
  • Eye Protection: If you’re not using a full-face respirator, wear goggles to protect your eyes from splashes.

Ventilation

Ensure good ventilation in the area where you are working. Using Rust Bullet in well-ventilated spaces helps to disperse vapors and reduce the concentration of harmful substances in the air.

Yes, Rust Bullet coatings can be used on wood applications. Rust Bullet products provide a durable, protective layer that can help prevent deterioration caused by moisture, mold, and mildew. Here are a few considerations and steps to follow when using Rust Bullet on wood:

1. Surface Preparation: The wood surface should be clean, dry, and free of any contaminants such as dirt, grease, or loose material. If the wood is previously painted or treated, any loose or peeling material should be removed to ensure good adhesion.
2. Priming: While Rust Bullet is self-priming on metal, applying a primer specific to wood might be beneficial, especially if the wood is very porous or weathered. This can help improve adhesion and overall finish.
3. Application: Apply Rust Bullet using a brush, roller, or spray equipment. Multiple coats, beyond the 2 coat minimum, may be required to achieve the desired DFT (dry film thickness) for optimal protection.
4. Drying and Curing Time: Allow adequate drying time as per the product guidelines. Full curing might take longer on wood compared to metal due to the nature of the substrate.
5. Finish: Rust Bullet typically leaves a glossy finish. If a different finish is desired, or if the wood is being used for aesthetic purposes where the appearance is important, consider applying a topcoat that complements the desired look.
6. Durability: While Rust Bullet provides a durable finish, the longevity of the application on wood can vary based on factors such as exposure to elements, the type of wood, and the specific environment.

Using Rust Bullet on wood can be an effective way to protect structures like wooden fences, decks, outdoor furniture, and other wood items from moisture and decay, especially in harsh or outdoor environments.

If the lid on your Rust Bullet can is bulging or appears to be under pressure, or your can has dents, it could be due to a few reasons. The number one reason for both of these occurrences is due to transport. The lid can start to bulge when chemical reactions within the paint produces gases, especially when the can is stored in varying temperatures, which is quite common throughout the shipping process. The gas build up can create pressure inside the can, cause the lid to bulge. Likewise, exposure to high temperatures can cause the the air and volatile compounds inside the can to expand, leading to increased pressure against the lid. We include security clips or ring locks on all products over 1/4 pint size to ensure your lid does not comes off during transit.

All the cans we ship out are in perfect condition, and any dents that may be noticed when your package arrives, are due solely to damage from transit. We package all of our products with amble bubble wrap and/or paper to protect the product. Our cans are also rated to withstand impact and dents without compromising the integrity of the can. If the can is dented, but no product appears to be leaking, the can has done its job and protected the product, and it will be completely fine to use.

Steps to Safely Handle the Situation:

• • Be Cautious: When opening a bulging can, wear protective gear like gloves and safety glasses. Gases or liquids could spray out when the seal is broken. We recommend you cover the lid with a rag before opening to prevent any spray getting on you or your surroundings.

• • Release Pressure Slowly: When opening the can, do so slowly and carefully to allow any built-up pressure to release gradually. You can gently tap the edges of the lid with a mallet to help loosen it before trying to pry it open.

Disposing of Rust Bullet coatings, or any similar type of paint and coating product, requires special attention to avoid environmental harm and comply with local regulations. Here are some general guidelines to follow when disposing of Rust Bullet coatings:

1. Check Local Regulations: Always start by checking with your local waste management authority for specific guidelines and regulations regarding the disposal of paints and coatings. Different regions may have different requirements based on the type of material and environmental laws.
2. Liquid Coatings: If you have unused liquid Rust Bullet coating, do not pour it down the drain, into sewers, onto the ground, or into any body of water. Such actions can cause environmental damage and may be illegal.
3. Solid Waste: If the Rust Bullet coating has hardened, it can often be disposed of as solid waste. Allow any unused product to dry out completely by opening the container and allowing it to harden. Once solidified, it can generally be disposed of in your regular trash, but you should still confirm this with local waste disposal regulations.
4. Recycling and Hazardous Waste Collection: Some areas offer recycling or hazardous waste collection services that accept paints and coatings. These facilities are equipped to handle such materials safely.
5. Unused Product: If you have a significant amount of unused product that is still in liquid form, consider donating it to someone who can use it, such as a local community center, theater group, or other organizations that might need paint for projects.
6. Safety Precautions: When handling and disposing of any chemical products like Rust Bullet, use appropriate personal protective equipment to avoid skin contact or inhalation of fumes.

Following these steps helps ensure that you dispose of Rust Bullet coatings responsibly and safely, minimizing any potential harm to the environment and aligning with local legal requirements.

Applying Rust Bullet to porcelain is generally not recommended. Porcelain is a very smooth, non-porous material, which means that coatings like Rust Bullet will have difficulty adhering to its surface, leading to peeling, flaking, or chipping of the finish over time.

If you’re looking to protect or alter the appearance of porcelain, it’s better to use products specifically designed for use on ceramic and porcelain surfaces. These might include certain types of ceramic sealants or coatings that are made to bond with glossy, non-porous materials.

Metal Blast is a rust remover and pre-treatment product that’s used to prepare metal surfaces before applying a Rust Bullet protective coating. It’s ideal for use when you want to ensure a clean, rust-free surface that allows for optimal adhesion of the coating. Here are some specific scenarios when you might use Rust Bullet Metal Blast:

1. 1. Restoration Projects: When restoring cars, bikes, boats, or any metal parts that have developed rust, Metal Blast can help clean and prep the surface.

1. 1. Preventative Maintenance: On metal structures or equipment that are beginning to show signs of rust, applying Metal Blast can halt the corrosion process and prepare the surface for a protective coating.

1. 1. Home Improvement: For DIY projects involving metal fences, gates, or outdoor furniture, Metal Blast can be used to clean and prepare the surfaces before coating.

1. 1. Industrial Applications: In industrial settings, where maintaining the integrity of machinery and infrastructure is crucial, Metal Blast can be used during routine maintenance to keep equipment in top condition.

1. 1. Marine Uses: For marine environments where metal is constantly exposed to saltwater and prone to rust, Metal Blast can help maintain and extend the life of metal components.

The exact balance of viscosity, solvent, and active ingredients must be maintained; therefore, Rust Bullet coatings should never be mixed with any other products. Mixing another coating or adding any other unapproved product to a Rust Bullet coating will compromise the performance and quality of the finished product.

All Rust Bullet coatings come in a gloss or satin finish, and we have not found any flattening agent that is compatible with our coatings that do not effect its performance. At this time, we do not have a matte/flat finish option, nor do we have any recommendations for lowering the sheen using a flattening agent. With the use of Tread-Tex (usually used on concrete applications for anti-slip), it will provide for a bit of gloss reduction on your finish, but will still not provide a matte finish to your coating.

Try to use a paint key, not a screwdriver. If the lid is still stuck, hammer the plug back into place and try prying it again. If that still doesn’t work, strike the plug dead center and it will release, every time.
Here is a video illustration of that process:

Listen for the POP when the plug releases. This works for gallons and quarts, ¼ pints might need a smaller hammer but will have the same result. The best part is, the plug will have a dent in it, but still be useable. Just hammer the dented plug back into place to seal the can.

When opening and closing the lid of a can of any paint, some of the coating can get on the rim. Rust Bullet has such amazing adhesion qualities, that it will literally glue the lid to the rim. It will happen more often with the smaller cans. Take care to wipe clean the rim of your can before resealing, or use a piece of plastic wrap to create a barrier between the can and lid before resealing.

Care should be taken to ensure that previously opened containers or left-over partial containers are kept sealed during storage. Rust Bullet coatings are moisture sensitive; limit the time the container is opened.

During application, pour out the portion that will be used in approximately one hour and reseal the lid as soon as possible. Immediately wipe clean any Rust Bullet from the rim of the container and reseal. This should be done every time Rust Bullet is used and in between coats. Never pour back any Rust Bullet coating that has been exposed to the outside air for any length of time because it will destroy the remaining product.

The shelf life of Rust Bullet coatings is at least two years for unopened containers and approximately one month for containers that have been opened. The product storage temperature range is 33°F to 120°F. Rust Bullet is a specialized moisture sensitive product; containers that have been opened should be used within a few months for proper coating performance.

Use Bloxygen to preserve Rust Bullet coatings for up to six months. Bloxygen is an inert Argon gas that can be floated over the top of the unused portion of the Rust Bullet Coatings just prior to properly resealing the lid. This will displace the oxygen and provide a much longer storage life for unused portions of previously opened containers.

Rust Bullet coatings improperly stored or stored beyond the recommended shelf life, opened or unopened, are not eligible for the product return policy as published by Rust Bullet, LLC.

There are several issues to consider when painting over fiberglass, especially if there has been an existing failing paint. One issue is the application of a new coating system over an older, failing coating and another is the application on a very delicate and porous surface.
Remove as much of the older coating as possible to alleviate its continued failure to influence the success of the new coatings. The fiberglass would need to be washed, allowed to dry, and then lightly scraped to remove surface paint, wax, or other contaminants.
A non-chemical method of removal is to lightly scrape as much paint off as possible. If too much pressure is applied, the fiberglass may be damaged. Using a heavy-duty sponge and warm water, coat the scrubbing surface of the sponge with baking soda. Scrub the fiberglass with the baking soda to remove any paint left behind after the scraping. The baking soda will be a bit more labor intensive but will avoid damage that comes with chemical strippers or paint thinner when used on fiberglass. Thin, multiple coats of urethane are the recommended coating for application on the fiberglass, so Rust Bullet is very suitable for the job. A recommended 12 mil dry film thickness of Rust Bullet Automotive should be achieved prior to the application of the desired topcoat or four coats. As the fiberglass will tend to be porous and the applied coats thin, more coats of the Rust Bullet will be needed than usual to achieve the appropriate film thickness on this project.

Wait approximately one hour before applying a topcoat over the final coat of Rust Bullet Industrial or Rust Bullet Automotive that has been accelerated with Rapid Fire. The previous coat should be tack free.
IMPORTANT: A Rust Bullet coating that has not been accelerated by adding Rapid Fire can be top coated between approximately two to six hours after the application of the final coat of Rust Bullet with no additional preparation.

• The Rust Bullet Application Guidelines contain complete detailed clean-up information. Application equipment must be cleaned immediately after use to avoid damage. Spills must be cleaned up immediately with Rust Bullet Solvent or the product will harden and become next to impossible to remove.
• Avoid getting paint on your body, clothes, or any surface not intended to be coated. Rust Bullet coatings are permanent; after curing, Rust Bullet can only be removed with rigorous abrasive action. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the label. Washing with soap and water may work, if done immediately.
• Use Rust Bullet Solvent for Cleanup. Do not make assumptions about other cleanup solvents without consulting Rust Bullet Customer Support. Even a very small contamination of Rust Bullet with alcohol or other hydroxyl-containing solvents can destroy the moisture-cure reaction partly or entirely without any indication or jelling.
• Spills must be cleaned up with Rust Bullet Solvent immediately or the product will harden and become next to impossible to remove.
• Application equipment must be cleaned with Rust Bullet Solvent immediately after use to avoid damage. Thoroughly flush equipment with Rust Bullet Solvent. Do not leave residue as it will harden and become insoluble in solvent. Clean equipment as you would with any typical two component catalyzed coating. Always clean brush or roller thoroughly. Dunking dirty equipment in Rust Bullet Solvent will not prevent the coating from curing overnight. While not recommended, if you want to clean your brush, you will need to soak, dab, massage, scrub, comb, and wipe as appropriate, to dissolve, clean, and thoroughly remove the coating. This can require numerous soaks with clean solvent for each soak and should be repeated until the solvent used to clean remains clean and clear, indicating the coating has been completely removed. We recommend that you consider using less expensive brushes and rollers that can be discarded after use rather than cleaned.

• NOTE: If Rust Bullet Solvent is unavailable, Xylene, Toluene or MEK may be substituted.

Take precautions to avoid contact with Rust Bullet products and the eyes, skin, clothing, or other objects not intended to coat. Wear the most appropriate protective clothing, gloves, and eye protection during set up, application, and clean up. If Rust Bullet coatings contact the skin, immediately wash with soap and water for at least five minutes. Rust Bullet that has dried on the skin will wear off in approximately seven to ten days. Refer to the Rust Bullet MSDS Section 4 First Aid Measures for additional information.

When there is an existing coating that exhibits poor adhesion and is flaking off, any coating applied over that coating is subject to the same behavior. As this coating continues to lose its bond with the substrate, the Rust Bullet or any coating on top would pull up or bubble.

Scuff up the surface and apply several coats of Rust Bullet to extend the life. Although it will provide protection and longevity, it will not have the optimum performance of an application over a surface that does not have an existing coating failure. To achieve maximum adhesion and performance, it is always recommended to remove any old paint or coating before applying Rust Bullet.

If you have bubbles, also know as solvent pop, on your finished coating, it is likely due to one of these common reasons. Excessive bubbling or a textured surface is also know as orange peel, and is usually caused by these same factors.

Some of the most common reasons for bubbling are:
• Applying Rust Bullet too thick. As Rust Bullet cures, small gas bubbles can get trapped in overly thick areas of the coating, creating bubbles in the finish, called solvent popping. When using a brush or roller, Rust Bullet should be applied evenly without buildup in a crosshatch method (an up and down, side to side continuous motion).
• Prematurely applying a subsequent coat over a partially wet previous coat will trap the escaping gas during the curing process causing bubbles in the finished coating.
• Shaking the can creates air bubbles in the product. Prior to application, Rust Bullet must be stirred thoroughly until completely uniform and homogeneous (approximately 3 minutes). Shaking the container may cause the formation of bubbles in the finish of the coating.
• Using a mechanical tool to stir or mix the coating will cause a vortex, drawing air into the product. Avoid whipping air into product as the same results will occur as noted above.

Fossil fuels, such as refined oils (gasoline, diesel, jet fuels and kerosene) will not affect the integrity of a cured Rust Bullet coating. Additionally, renewable fuels such as Biodiesel and Ethanol will have no adverse effect on substrates coated with Rust Bullet.

Rust should not be coming to the surface unless Rust Bullet was improperly applied. Wipe down the coated surface with Rust Bullet Solvent and inspect the surface to rule out the possibility that the rust stains are caused by rusty water or fluid that has dripped onto the surface coated with Rust Bullet from another area that was not coated. If another application of Rust Bullet is necessary due to an inadequate initial application, scuff up the surface with 80-100 grit sandpaper and apply an additional two coats of the Rust Bullet coating. Remember, surfaces to be coated must be completely dry.

When applying additional coats of Rust Bullet coatings, the previous coat should not be wet or too tacky; if you are unable to transfer the coating to a gloved finger, the surface is ready for an additional coat.
The approximate drying time between coats is two (2) to six (6) hours for Rust Bullet coatings, depending on humidity levels. When excessive wet film is applied, additional cure time will be necessary. Rust Bullet coatings are moisture sensitive; in high humid conditions of 80%+, Rust Bullet will cure much faster than it will in lower humidity. When applying additional coats from one day to the next, especially in the morning, make sure there is no dew or condensation on the previous coat. The surface to be coated must be completely dry.

Rust Bullet Rapid Fire Accelerator can be added to the Rust Bullet coating to decrease the normal recoat time of two to six hours to approximately 30 to 60 minutes per coat. Rapid Fire makes it possible to apply multiple coats of Rust Bullet in a single day and reduces project completion time by as much as 80%. A Rust Bullet coating accelerated with Rapid Fire can be applied with either an HVLP Spray System or an Airless Spray System. For maximum rust prevention, ensure that corners, edges, and heavily pitted areas are adequately covered. Apply an adequate number of coats sufficient to achieve the DFT (dry film thickness) appropriate for the project.

A Rust Bullet topcoat should be applied within the standard recoat times of two to six hours. If 12 or more hours have lapsed, wait for Rust Bullet to harden for at least 24 hours then lightly scuff with 80-100 grit sandpaper; enough to break the glaze to create a surface profile.

If a spray application of Rust Bullet has been accelerated by adding Rust Bullet Rapid Fire Accelerator, a topcoat may be applied approximately one hour after the final coat of the accelerated Rust Bullet coating has been applied.

If using a premium finishing paint or any other topcoat other than Rust Bullet, it is recommended to refer to the manufacturer for compatibility and application requirements. This will typically require Rust Bullet to reach a full cure and then scuff the surface with 80-100 grit sandpaper to break the glaze and create a profile. Always confirm with the manufacturer prior to application.

The drying time between coats of Rust Bullet is approximately two to six hours. If 12 or more hours have lapsed, wait for Rust Bullet to harden for at least 24 hours then lightly scuff with 80-100 grit sandpaper; enough to break the glaze to create a surface profile. This will allow proper adhesion of additional coats.

After curing, all Rust Bullet coatings have a service temperature range of 314°F (157°C) continuous and can tolerate maximum temperatures between 617°- 662°F (325°-350°C) for up to 72-hour periods.

No. The extreme heat involved in the welding process will disintegrate Rust Bullet, and most other coatings. If welding is necessary after Rust Bullet has already been applied, then it should be removed prior to welding, and reapplied afterward.

Yes. If, for any reason, Rust Bullet is transferred to another container; clean, unlined, metal paint cans (or similar unlined metal containers) must be used. Make sure that the container can be properly sealed. Stir the contents for at least three minutes before transferring any portion of product to a different container. Use Bloxygen to displace the oxygen with an inert gas (Argon) prior to sealing to prevent curing of previously opened containers of Rust Bullet coatings. During application, pour out the portion you will use in approximately one hour and reseal the lid as soon as possible. In all situations, you should minimize the time Rust Bullet coatings are left open and exposed to the air.

Rust Bullet coatings are ready to use right from the can. Due to the exact balance of viscosity, solvent, and active ingredients, it is not recommended to thin Rust Bullet coatings.

If you have been advised by Rust Bullet to thin your product, it is important to maintain formula balance; therefore, Rust Bullet coatings must only be thinned with Rust Bullet Solvent. Thinning or adding any other product to a Rust Bullet coating will compromise the performance and quality of the finished product. Use Rust Bullet Solvent for thinning at an approximate ratio of 3% – 5% by volume (i.e. 1.0 to 1.5 oz solvent per quart of coating). Rust Bullet Solvent should always be used when available. If unavailable in your area, acceptable alternatives would be Xylene, Toluene, or MEK. Do not use any other unapproved solvents for thinning.

Please consult with Rust Bullet Technical Support before thinning your product and do so only when advised.

Rust Bullet is moisture sensitive. It is extremely important that the surface to be coated is completely dry to allow proper curing and adhesion. Extreme care should be taken to ensure all coating projects are completely dry before, during, and for a minimum of 24hrs after application.

If it is made of iron or steel, it will rust and corrode if left unprotected. Rust Bullet should be applied even where rust is not apparent to prevent the occurrence of future corrosion. Rust Bullet not only kills existing rust, but it also seals and protects surfaces that have not yet started to rust, providing years of protection.

• Rust Bullet is a moisture cured urethane which means it is sensitive to moisture. This provides strong adhesive properties and durability but requires careful attention when handling and during application. The surface to be coated must be completely dry before, during, and after application to avoid potential failure. Ideally, keep the surface dry for at least 72 hours after application to allow a full cure before exposure to moisture.
• Never allow sweat, rain, mist or other contaminates to fall into a Rust Bullet coating. Even a drop or two can drastically affect results.
• Rust Bullet coatings require a surface profile for proper adhesion. The use of Rust Bullet Metal Blast for metal applications will etch the metal surface and provide the ideal anchor pattern to surfaces allowing superior adhesion of Rust Bullet coatings. Concrete applications require a Concrete Surface Profile (CSP) of 1 which is equivalent to about 120 grit sandpaper in texture and can be achieved by sanding with 60-80 grit sandpaper when needed.
• Rust Bullet coatings are ready to use right from the can. Thinning is not necessary. Adjust the application equipment as opposed to adjusting the coating.
• Rust Bullet coatings should be stirred thoroughly by hand for at least three minutes until homogenous. Do not shake the can or use mechanical means to mix. Avoid creating air bubbles in the coating during mixing.
• Only pour out what you intend to use in one hour and quickly re-seal the can. Wipe clean any coating from the rim of the container before resealing.
• Use Bloxygen to keep any leftover product from curing for up to six months. Bloxygen is an inert Argon gas that will displace the oxygen and provide a much longer storage life for unused portions of previously opened containers.
• Rust Bullet Solvent works best for cleanup, equipment prep, and thinning when needed. Do not use lacquer thinner, vinyl thinner, epoxy solvent, or any alcohol or unapproved solvent. If Rust Bullet Solvent is unavailable, Xylene, Toluene, or MEK may be substituted.
• When using spray equipment, flush Rust Bullet Solvent through pumps, lines, and guns prior to spraying to remove any existing moisture or other contaminates. Clean equipment immediately in between coats and when finished spraying to avoid product curing inside of the spray equipment.
• Apply it in thin, even coats. Thick coats will cause bubbling, also known as solvent popping, and eventually a coating failure.
• The optimum recoat time is between two to six hours, up to 12 hours. Touch the surface with a gloved finger about two hours after your last coat. If you have no transfer of paint, you are ready for your next coat. If 12 or more hours have lapsed, wait for the last coat to cure for at least 24 hours, then lightly scuff with 80-100 grit; enough to break the glaze to create a surface profile.

As Rust Bullet cures, it expels solvents and releases carbon dioxide gas while dehydrating the rust. The first coat of Rust Bullet soaks through the rust down to the metal below, encapsulates the rust and dehydrates it. As the first coat dries and gases off, tiny pin holes may form in the coating. The second coat is critical to fill any pin holes and seal the surface with an air-tight, armor-like shield of protection. If the pin holes are not sealed after the first coat, air and moisture may penetrate the coating exposing the surface to further damage. A two to three coat application typically achieves a DFT (dry film thickness) of the required 6 mils for general applications. Additional coats may be necessary to achieve the appropriate DFT for your project.

Brush – Regular bristle brushes. Do not use foam! Use cheaper types of brushes, as you will need to discard the brush when finished. A brush application achieves approx. 2 mils per coat.
Roller – Use a 3/8-inch microfiber nap roller. Do not use a foam roller. A roll application achieves approx. 2 mils per coat.
Spray Equipment:
Airless – Rust Bullet Industrial, DuraGrade Concrete, and Rust Bullet for Concrete can be applied using airless spray equipment. A 517 to 523 tip at approximately 3000 5000 PSI is recommended and will give you about 3-4 mils per coat.
HVLP – Rust Bullet Automotive, BlackShell, WhiteShell, and DuraGrade Color may be applied with HVLP (High Volume, Low Pressure) spray equipment. Use a 1.7mm to 2.0mm size tip, depending upon the equipment, at 40-60 PSI. An HVLP application gives about 2-3 mils per coat.

• Do not open Rust Bullet coatings until ready to use to maintain product shelf life.
• Do not open and stir a Rust Bullet coating when the temperature is below the dew point.
• Rust Bullet coatings should be stirred thoroughly for at least three minutes or until completely uniform and homogenous (avoid whipping air into product). Shaking the container prior to application may cause the formation of bubbles in the finish of the coating. Never stir the product by mechanical means; this will trap air molecules containing moisture between the coating and the surface causing improper curing and possible coating failure.
• Rust Bullet products that have been sitting for six months or longer may develop settling. Follow the same stirring instructions but increase the stir time and be sure to break up any clumps on the bottom of the container, if any.
• Pour out what you intend to use in one hour and immediately wipe clean the rim of your container and reseal to preserve coating.
• Never pour any unused coating back into the container as it will contaminate the entire can.

Both the Industrial and Automotive formulations have the same patented anti-corrosive properties and will outperform any other rust inhibitive, protective coating on the market. Rust Bullet Automotive is formulated to easily flow through an HVLP automotive spray system and will produce a smoother finish typically needed for automotive projects. What is the recommended surface preparation for Rust Bullet coatings? The surface to be coated must be completely dry and must be free of loose rust, paint, moisture, dirt, mildew, oily substances, wax and loose particles, or any other surface contaminates such as embedded chlorides etc. Remove any loose rust, loose paint, or loose mill scale by lightly scraping, sanding, media blasting or wire brushing. For a one-part solution, we recommend cleaning the surface with Rust Bullet Metal Blast which not only cleans your surface, but conditions it, allowing for optimal adhesion of Rust Bullet coatings. No additional surface preparation should be necessary. If there is existing paint on the surface, lightly scuff the surface to create a profile for adhesion. Rust Bullet works best when in direct contact with the rusted surface or bare metal, so previous paint should be removed as much as possible. Refer to the Application Guidelines for more information.

Rust Bullet Industrial and Rust Bullet Automotive are super-tough, high-performance, industrial grade coatings that can be applied on new, clean metal or directly over surface rust, providing permanent corrosion protection with phenomenal adhesion. Rust Bullet has been awarded an unprecedented two U.S. patents by the United States Patent and Trademark Office.

Rust Bullet Automotive is for automotive applications whereas Industrial is for commercial, industrial, home and farm, and marine applications. These coatings contain an aluminum flake which provides unmatched protection in salt heavy environments such as saltwater, coastal cities, areas with heavy road salts during winter months, and more. This aluminum flake also provides a sacrificial element which corrodes preferentially and protects the metal surface underneath.

DuraGrade Color is our new Low VOC rust inhibitor for metal applications. The resins in the coating are different – they are stronger than our original coatings. Because the resins are stronger, aluminum flake is not needed, and unlike Rust Bullet Automotive, we can pigment this product. This provides a colored finish and only one type of coating is needed to complete a project.

Apply two coats of DuraGrade Color to the metal surface and that is it.

Use DuraGrade Color as a topcoat to either Automotive or Industrial, providing the best of both worlds. The combined protection creates the strongest armor tough coatings available. No matter the choice, Rust Bullet coatings are meant to stop rust and prevent it from returning to the surface to which it is applied.

Rust Bullet for Concrete is an industrial strength protective moisture-cured urethane coating specially formulated for concrete. It contains aluminum flakes that create a super strong barrier to keep moisture, oxygen, and other contaminants from reaching the surface. These overlapping aluminum flakes add longevity, strength, and durability.

This special formulation improves the appearance of concrete, and provides an impervious shield allowing easy clean-up of oil, grease, and chemical spills. Finally, it provides strong protection against impacts, abrasives, and atmospheric elements. Use for all concrete flooring needs including garage floors, walkways, paths and much more.

If a different color other than metallic gray is desired, topcoat with a second coating such as DuraGrade Color.

DuraGrade Concrete does not contain this aluminum flake; however, this new Low VOC resin is stronger than our original formulation. This new resin gives DuraGrade Concrete longevity, strength, and durability. AS DuraGrade Concrete comes in 18 colors, only one product is needed to protect your floor.

DuraGrade Concrete is a bit thicker than Rust Bullet for Concrete, however it is still applied in thin even coats.

DuraGrade Clear is a high-performance, ultra-low VOC, rust inhibitive and protective coating. It’s scratch, chip, chemical and UV resistant and is ideal for indoor or outdoor surfaces. Use this to seal Rust Bullet decorative flakes.
With just 49 g/l of VOCs, DuraGrade Clear’s patent pending formula is an environmentally preferred ultra-low VOC coating compliant in every state and air quality management district.

DuraGrade Clear can be used as a stand-alone coating or as a topcoat and can be applied directly onto clean or rusted metal, concrete, wood and other surfaces. DuraGrade Clear has superior adhesion and provides excellent corrosion protection and abrasion resistance.

DuraGrade Clear is easy to apply by brush, roller, or spray equipment. Dries to a water clear finish.

BlackShell, WhiteShell, and Clear Shot are formulated specifically as topcoats for Rust Bullet Industrial, Automotive and Concrete formulations. In addition, they can be used as a stand-alone coating and provide exceptional corrosion protection. We must mention that they create a stronger and more durable protective shield when applied as a topcoat. All these products give a beautiful gloss finish and are scratch, chip, and UV resistant. They also offer unbeatable chemical resistance.

Rapid Fire Accelerator is designed for spray applications of Rust Bullet coatings. Rapid Fire decreases the drying time needed between coats, ultimately reducing project completion time up to 80% while maintaining optimal coating performance.

ProPlus is our bargain version of Rust Bullet Automotive. It’s a slightly thinner formula than Rust Bullet Automotive and provides superior coverage for rust protection. If you’re looking for rust prevention on a budget, consider Pro Plus.

ProPlus patent-pending formula is low in VOCs providing VOC compliance in all 50 states. ProPlus has outstanding adhesion to concrete surfaces and is scratch, chip, chemical and UV resistant, requiring no primer, basecoat, or topcoat

Metal Blast is a metal surface cleaner and conditioner that’s like three products in one – it dissolves rust, degreases the surface and it etches metal. Metal Blast eliminates the high cost of surface preparation by properly etching surfaces with minimal or poor adhesive qualities and providing an ideal anchor pattern for a superior coating bond. It works on any metal surface including aluminum, stainless steel, and shiny polished metal.

Metal Jacket is a non-greasy, non-dirt collecting, non-tacky, dust retardant, continuous, flexible, removable film that will not crack, peel, or flake. Metal Jacket protects all metals against atmospheric rust and corrosion, salt spray, high humidity, chemical fumes, abrasive matter, fingerprinting and fingerprint corrosion. This translucent coating allows for easy reading of identification markings stamped on parts.

Rust Bullet Solvent is for cleanup, equipment prep, and the thinning of Rust Bullet coatings. Effectively clean equipment such as paint pots, lines, guns, brushes, and rollers, as well as spills, drips and overspray. Use to thoroughly flush and clean spray equipment before, after and between coats to avoid possible damage to spray equipment. Do not thin unless directed by Rust Bullet Technical Support. The approximate thinning ratio is 3% to 5% by volume (i.e. 1 to 1.5 oz. solvent per quart of coating).

Bloxygen blocks oxygen and protects, and preserves opened Rust Bullet coatings during storage. Bloxygen uses ultra-pure Argon, an inert gas, to drive the oxygen out of partially used containers of Rust Bullet coatings and will preserve the coating for up to six months. A short spray into the container will protect the Rust Bullet from reacting with the oxygen or moisture present in our normal atmosphere.

The Rust Bullet Products SDS documents contain all safety recommendations for preparation, application and clean up, and can be found here: Rust Bullet Products Technical Documents

A certain degree of risk is involved in the use, or more properly, the misuse, of most industrial materials; Rust Bullet is no exception to this rule.

Ensure adequate ventilation and fresh air when working with Rust Bullet coatings. Use a NIOSH-approved Half-Mask Organic Vapor Respirator and a P100 filter attached with a filter cover. Filters must be changed when they become saturated. Wear protective clothing, gloves, and eye protection during set up, application, and clean up. It is critical to avoid any conditions that may cause a fire. Avoid open flames, pilot lights, sparks, heating elements, cigarettes, or all possible sources of ignition.

Warning! If you scrape, sand, or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NOSH-approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.EPA.GOV/LEAD.

Rust Bullet’s Application Guidelines are included with every order and can also be found on our Application and Technical Documents page. For the best possible results, it is extremely important that these Application Guidelines are read thoroughly before using Rust Bullet products. The selection of the right coating system should be based on an analysis of the target substrate and of the typically occurring atmospheric exposures. Rust Bullet, LLC is at your disposal to assist in this process. The information in Rust Bullet’s FAQs and Technical Data is based on extensive laboratory testing, combined with field experience. However, Rust Bullet, LLC makes no warranty nor assumes any liability or obligation in connection with its use. This edition cancels all previous editions. Data is subject to change without notice.

Rust Bullet Concrete coatings should be inspected annually for any visual cracks or chips. If any breaches in the coating are found, simply scuff the problem area, and apply an additional one to two coats to that area. If your concrete floor is subjected to high traffic and/or heavy machinery, a biannual inspection should be implemented. Using a dry film gauge is a great method of checking for coating wear.

Rust Bullet has not obtained certification from the Food and Drug Administration (FDA) for use on surfaces that come into contact with food, water or food service equipment. We cannot recommend Rust Bullet Concrete coatings be used in that capacity.

Rust Bullet was subjected to a Potted water test that conforms to the United States Environmental Protection Agency (EPA) and State of Nevada primary and secondary drinking water standards. This EPA Laboratory test approved Rust Bullet to meet the standard for both primary and secondary drinking water. You can view the test results HERE.

A cured Rust Bullet Concrete coating provides an impervious shield, allowing easy clean-up of oil, grease, chemical spills, etc. along with strong protection against impact and abrasives. You can use all common cleaning methods, from simply sweeping or vacuuming, to mopping with soap and water or even power washing to clean your floor.

Yes, Rust Bullet Concrete coatings are extremely versatile and may be used effectively on metal and wood applications. A minimum of two coats are required and you must follow the same two to six hour recoat time. Refer to the Application Guidelines for DuraGrade Color for additional information on application to a metal surface.

Spills must be cleaned up with Rust Bullet Solvent immediately or Rust Bullet Concrete coatings will harden and become next to impossible to remove. Rust Bullet coatings are permanent after curing, Rust Bullet can only be removed with rigorous abrasive action with a mechanical grinder/sander. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the container. If Rust Bullet gets on skin, wash with soap and water immediately. Protect any surface you do not want coated and wear protective equipment to keep yourself paint free.

NOTE: If Rust Bullet Solvent is unavailable, Xylene, Toluene, or MEK can be used as an acceptable substitute.

Rust Bullet Concrete coatings will be fully cured within 3-5 days. Do not put heavy items on the floor during this time. If you have a vehicle with performance tires, it is recommended to wait 7-10 days before pulling onto the floor immediately after driving. Please see “Does Rust Bullet protect against hot tire pickup” for additional details about parking on your newly coated floor.

Wait a minimum of eight hours before walking on a coated floor. When applying additional coats to your floor within the two to six hour recoat window, it is recommended to wear spiked shoes to avoid leaving footprints on the floor. Do a test in an inconspicuous place before walking on it. This time may increase in areas with low humidity.

No, we do not recommend the use of Rust Bullet Clear Shot to seal in your flakes. Alternatively, we recommend the use of DuraGrade Clear because this formula provides a higher build, allowing each coat to yield more durability. DuraGrade Clear is our toughest coating, and therefore the best option for lasting protection in abrasive environments!

Yes, Rust Bullet Decorative Flakes make a great addition to any concrete project to enhance aesthetics. Apply Decorative Flakes when the last coat of Rust Bullet is wet. Spread the flakes on a wet coat, working in sections. Once the flakes have been spread, follow the standard recoat time of two to six hours and seal the flakes with Rust Bullet DuraGrade Clear.

If doing a light to medium broadcast of flakes, one (1) coat of DuraGrade Clear will suffice to seal the flakes. If doing a heavy to full broadcast, we recommend applying two (2) coats of DuraGrade Clear to properly seal the flakes. If a slip resistant surface is desired, Tread-Tex non-skid additive should be added to the final coat of DuraGrade Clear.

TIP: Flakes are best distributed by two people – one person rolling the coating while the other person distributes the flakes. If working alone, make sure you work in sections and apply the flake while your coating is still wet.

No, a topcoat is not required. Rust Bullet Concrete coatings are a single component coating which is designed to provide durable protection against impacts and abrasions as well as chemical and acid spills. It is UV resistant to help ensure the coating does not degrade or discolor when exposed to sunlight. This makes Rust Bullet suitable for outdoor applications where it will be exposed to direct sunlight and harsh weather conditions.

Rust Bullet works best when it is in direct contact with the substrate; remove as much existing paint as possible. If there are areas that are tightly adhered, create a proper profile for adhesion by sanding the existing paint with 80-100 grit sandpaper. This will provide an anchor pattern to the surface before applying Rust Bullet Concrete coatings.

Note that if the existing coating is failing, Rust Bullet will be subject to this same behavior because it is adhered to the failing coating and not the substrate itself. Only apply to existing coatings that are in good condition and exhibit strong adhesive properties. For the best results, it is recommended to remove all existing coatings prior to application of Rust Bullet Concrete coatings.

When using Rust Bullet Concrete coatings on your floor, roller marks generally appear because the thickness of the coating is not even throughout. When rolling each section, watch the already coated sections for roller marks. If they appear, take the roller without adding more paint, and with no pressure on the roller handle, roll over the coated surface to even the coats out. For continuous issues with roller marks, pay attention to how much paint is being applied at one time and make sure the coats are thin and even. Also, use a clean, dry roller and lightly back-roll over the coating. This will generally even the coat out and hide roller markers. Rust Bullet Decorative Flakes are also a great way to hide imperfections in your concrete floor, including roller marks!

Ideal application temperature is between 50°F (10°C) and 90°F (32°C) with humidity between 30% and 70%. Never apply a Rust Bullet coating while raining or under threat of rain. Do not apply to surfaces when the existing temperature of the surface exceeds 190°F (90°C), is below 32°F (0°C), or the humidity is above 90%.

Optimum dry time between coats is two to six hours, not to exceed 12 hours. The previous coat should not be wet or too tacky; if there is no transfer of the coating to a gloved finger it is safe to apply an additional coat. If 12 hours or more have lapsed, wait at least 24 hours, and lightly scuff the surface with 80-100 grit sandpaper to break the glaze of the coating and provide a profile for inter-coat adhesion. This 12-hour time frame is decreased in higher humidity areas. It is recommend to wear spiked shoes when applying additional coats to your floor to prevent footprints. Even though the coating is dry to the touch and ready for additional coats, it is not completely cured and may potentially leave footprints if walked on.

Rust Bullet Concrete coatings require a minimum of two coats to seal the surface. Additional coats are recommended for high traffic areas and commercial or industrial applications. A minimum 6-8 mil DFT (2-3 coats) is required for residential applications, and a minimum 10-12 mil DFT (4-5 coats) is recommended for commercial and industrial applications.

Rust Bullet Concrete coatings can be applied by brush, roller, or spray equipment. If using a brush, use ones that can be discarded when the project is completed. If using a roller, use a 3/8″ microfiber nap roller. Do not use foam brushes or foam rollers. If using spray equipment, use an airless sprayer with a 517-523 size tip at 3000-5000 PSI. The best method depends on the applicator and their experience, and the application equipment. Spray application will give the smoothest, most even finish. A roller and brush combo is the most common method of application. Use a brush to do your edging and along expansion joints, and a roller for the larger areas. This method works well with two people, one using a brush and the other following behind and rolling the area in each section.

Use a mild detergent such as dish soap and water or Simple Green. Power washing is not recommended as to avoid introducing too much water to the concrete prior to application. Do not use any other type of chemical without asking Rust Bullet Technical Support. Not all products are compatible with Rust Bullet Concrete coatings.

Typically, porous floors are a good thing, up to a point, when applying any concrete coating. It enables the coating to achieve a good mechanical bond to the substrate. One thing to consider, however, is that it will reduce the coverage rate and DFT (dry film thickness) of the initial coat, so you may need additional product to account for the absorption on the first coat. It is very rare situations that a penetrating sealer should be used, and in cases where the floor is extremely porous, a densifier is usually a better option, but will require grinding of the surface after the 5-7 day reaction time needed to work. In most all cases, you do not want to use a sealer or densifier, and applying additional coats Rust Bullet concrete coatings to achieve the appropriate DFT will give the best results.

No, acid etching is not required nor is it recommended.

Theoretical coverage is approximately 300-350 sq/ft per gallon, per coat depending on the method of application and the porosity of the surface. Generally, on a concrete surface, the first coat will take the most coating as it seeps into the pores of the concrete. The second and subsequent coats will take less.

Rust Bullet coatings can offer significant protection against hot tire pickup due to their durability, chemical resistance, and heat resistance. For optimal results, follow the application guidelines carefully and ensure proper surface preparation and curing. Regular maintenance can further enhance the coating’s performance and longevity. If hot tire pickup is a significant concern, it may be beneficial to Contact Us to ensure you are using the most appropriate product and application method for your specific needs.

Benefits of Rust Bullet Concrete Coatings:

1. 1. Durability: Rust Bullet coatings are designed to be extremely durable, providing a hard and resilient surface that can withstand heavy use and traffic. This durability can help reduce the likelihood of rubber adhering to the surface.
   2. Chemical Resistance: Rust Bullet products offer excellent resistance to chemicals, including those found in rubber tires. This chemical resistance can prevent the rubber from reacting with the coating and sticking to it.
   3. Heat Resistance: Rust Bullet coatings are formulated to withstand high temperatures, which can help mitigate the effects of hot tires on the surface.
   4. Ease of Cleaning: The hard, non-porous surface created by Rust Bullet can make it easier to clean rubber deposits and other debris, helping to maintain the appearance and functionality of the coated surface.

Application Tips for Best Results:

1. Proper Preparation: Ensure the concrete surface is properly prepared before applying Rust Bullet. This includes cleaning, degreasing, and profiling the surface to ensure good adhesion.
2. Multiple Coats: Apply multiple coats of Rust Bullet as recommended per your application purposes. This can enhance the protective properties and create a thicker barrier against tire pickup.
3. Curing Time: Allow sufficient curing time for the Rust Bullet coating. Proper curing is crucial to achieve maximum hardness and resistance.
4. Regular Maintenance: Even with a durable coating like Rust Bullet, regular maintenance and cleaning can help prevent buildup and extend the life of the coating.

Mitigation Strategies:

1. Proper Curing: If Rust Bullet is not allowed to cure properly before the vehicle was parked on it, the surface might be more susceptible to tire pickup. Proper curing ensures the coating reaches its maximum hardness and resistance. If you have a vehicle with performance tires, it is recommended to wait 7-10 days before pulling onto the floor immediately after driving.
2. Cool Down Period: Allow the tires to cool down before parking the vehicle on the coated surface. This can help reduce the temperature of the rubber and minimize the chance of pickup.
3. Surface Maintenance: Regularly clean the surface to remove any rubber deposits before they become ingrained. Using a degreaser or specific cleaning agents designed for concrete coatings can be effective.
4. Mats or Pads: Use parking mats or pads under the tires to create a barrier between the hot tires and the coated surface.
5. Temperature Control: If possible, keep the garage or area with the coated surface cool to reduce the chances of tire pickup.

NOTE: When a vehicle is driven, the tires can become very hot, especially after long drives or high-performance driving. When these hot tires come into contact with the concrete coating, the heat can cause the rubber to soften and transfer to the surface. High-performance tires or tires with softer rubber compounds are more likely to leave rubber deposits on the surface because they are designed to provide better grip through softer, stickier rubber.

In most cases, yes. However, it is the responsibility of the user to ensure the surface temperatures are within Rust Bullet tolerances. After curing, all Rust Bullet coatings have a service temperature range of 314°F (157°C) continuous and can tolerate maximum temperatures between 617°- 662°F (325°-350°C) for up to 72-hour periods.

Concrete sealers will prevent Rust Bullet Concrete coatings from achieving good adhesion to the surface. In most cases, the surface will need to be ground to remove this sealer and create a profile for adhesion. This can be done mechanically or by hand and a basic adhesion test should be performed prior to application.

Removing a concrete sealer by grinding involves several steps and requires the right tools and materials. Here’s a general guide:

1. Preparation:

   • Clean the concrete surface thoroughly to remove any debris, dirt, or grease.
   • Ensure the area is well-ventilated and wear protective gear (gloves, mask, goggles).

2. Tools:

   • Use a concrete grinder or a floor polisher with a diamond grinding wheel.
   • Ensure the grinder has dust collection capabilities to minimize dust spread.

3. Grinding Process:

   • Start with a coarse diamond grinding wheel (16-30 grit) to break through the sealer layer.
   • Make multiple passes over the concrete surface, ensuring even coverage.
   • Gradually move to finer grit wheels to smooth the surface and remove any remaining sealer residue.

4. Cleanup:

   • Vacuum the area to remove dust and debris.
   • Optionally, rinse the surface with water and allow it to dry completely.

5. Inspection:

   • Check for any remaining sealer spots and repeat grinding if necessary.

Note: The amount of grinding needed depends on the thickness of the sealer and the concrete’s condition. It can be a labor-intensive process, so take breaks and ensure the equipment is used correctly to avoid damage to the concrete.

Rust Bullet Concrete coatings are moisture sensitive. Even the smallest amount of moisture on the surface can cause a coating failure. A moisture meter, calcium chloride test, or a plastic sheet test can be conducted to check for moisture.

To perform the plastic sheet test for moisture, cut a sheet of plastic into roughly a 1’x1′ square (one side cut from a gallon resealable bag works great) and tape the edges onto the floor. Make sure to completely seal the edges so no air can escape. Leave it for 24 hours. Look for condensation on the underside of the plastic sheet or a visible darkening of the slab below the plastic that is damp to the touch. Both are signs of an excessively moist floor.

Another way is to use a moisture meter or calcium chloride test kit which are sold at home improvement stores. Follow the provided directions if using either of these methods.

Yes, Rust Bullet Concrete coatings may be applied to unsealed concrete after the concrete has fully cured. If a fresh pour is done with the intent to coat with Rust Bullet, you want a rough or broom finish. Do not have the floor power troweled and do not use a sealer. It is also recommended to perform a moisture test to ensure the concrete is completely dry throughout prior to application and follow all provided guidelines.

To perform a moisture test, take a piece of plastic (one side cut off a gallon resealable bag works great) and tape it to the floor on all edges, making sure its sealed on all sides. Wait 24 hours and inspect to see if there is condensation or darkening of the concrete in this spot. If there is a darkening or condensation, this indicates moisture is still present and the concrete is not ready to coat. Do this in a few places, going from the outside edges to middle of the floor to ensure it is dry throughout.

Rust Bullet Concrete coatings are ideal for most concrete surfaces. The concrete substrate must be structurally sound, thoroughly clean, and dry. Make sure the substrate is free of loose paint, moisture, dirt, mildew, oily substances, wax, loose particles, and other debris, prior to application. New concrete must be cured at least 30 days, and it is highly recommended to perform a moisture test prior to application to ensure there is no embedded moisture in your surface.

Yes. Rust Bullet Concrete coatings are easy to apply and can be used by anyone from DIY consumers to professionals. This FAQ section is a great resource if you have any questions, and as with any project, it is a good idea to review the product Application Guidelines beforehand to familiarize yourself with the product details. We are also happy to lend any support if you can’t find the answer to your question, simply Contact Us and we will typically reply within 24-48 hours.

Preparing your floor properly is essential for achieving the best results with Rust Bullet Concrete Coatings. Here are the steps you should follow:

1. Clean the Surface

• • Remove Debris: Sweep or vacuum the floor to remove dust, dirt, and loose debris.

• Degrease: If there are any oil or grease stains, use a degreaser to clean these areas thoroughly. Use a gentle detergent such as dish soap mixed with water and avoid introducing too much water to the surface during cleaning.

2. Repair Any Damage

• • Cracks and Holes: Fill any cracks or holes with an appropriate concrete repair product, compatible with a moisture cured urethane. Make sure the repair material is fully cured and lightly scuff before proceeding.

3. Ensure a Proper Profile

• Profile Requirements: Rust Bullet requires a Concrete Surface Profile (CSP) of only one (1) for application. This is equivalent to about 120 grit sandpaper in texture. (see image below)
• Adhesion Test: Pour 1oz of water on your floor, if it is absorbed within 30-60 seconds, your floor has an adequate profile. If the water beads up and is not absorbed, you will need to sand to create the appropriate CSP.
• Sand if Needed: If your floor has a smooth finish, it will likely need to be sanded to provide a profile. Rust Bullet does not require diamond grinding or etching of the floor, and typically 80 grit sandpaper on an orbital or pole sander will suffice. If you have a rough or broom finish, you likely have a sufficient CSP.

4. Check for Moisture

• Moisture Test: Perform a moisture test to ensure the floor is dry enough for coating. Tape a piece of plastic to the floor and leave it for 24 hours. Look for condensation on the underside of the plastic sheet or a visible darkening of the slab below the plastic that is damp to the touch. Both are signs of an excessively moist floor.
• Confirm No Moisture: Rust Bullet is a moisture cured urethane and it is imperative for proper adhesion that the surface is completely dry. If you have any signs of moisture, do not apply! Only apply the coating after you have confirmed there is no residual moisture in your floor.

5. Final Cleaning

• • Vacuum or Sweep Again: Make sure the floor is completely free of dust and debris.

• • Tack Cloth: For a final touch, use a tack cloth to remove any fine dust particles.

6. Masking and Protection

• • Mask Off Areas: Use painter’s tape to mask off any areas you do not want to coat, such as walls and baseboards.
  nnnn
  • Protect Adjacent Areas: Cover nearby surfaces with plastic sheeting or drop cloths to protect them from splashes and spills.
  nnnn
  • Wear Proper PPE: It is recommended to wear gloves, protective clothing, protective eyewear, and an organic vapor respirator when working with Rust Bullet.

NOTE: Rust Bullet coatings are permanent after curing, Rust Bullet can only be removed with rigorous abrasive action with a mechanical grinder/sander. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the container. If Rust Bullet gets on skin, wash with soap and water immediately.

7. Ensure Proper Ventilation

• Ventilation: Make sure the area is well-ventilated during application and curing. Open windows and doors or use fans to promote air circulation. Be cautious when circulating air as this can increase the risk of particles coming into contact with the coating while drying, and becoming permanently stuck in the cured coating.

Once these steps are completed, your floor will be properly prepared for applying Rust Bullet Concrete Coatings. Following these preparation steps carefully will help ensure a smooth, durable, and long-lasting finish.

When comparing Rust Bullet Concrete coatings to an Epoxy coating, there are several specific advantages to consider, particularly in terms of application, durability, and maintenance:

1. Ease of Application: Rust Bullet Concrete coatings are a one-part, multiple coat process. This means there are no precise, messy mixing ratios. Rust Bullet is easier to apply as it often does not require the extensive surface preparation (like acid etching or grinding) that epoxy coatings might need. This makes Rust Bullet a more user-friendly option for non-professionals or for situations where quick, efficient application is needed.
2. No Primer Required: Unlike many epoxy systems, Rust Bullet can be applied without a primer. This reduces the number of coats, labor, and overall time required for application.
3. Durability and Resistance: Rust Bullet Concrete coatings are known for their durability and resistance to a variety of chemicals and abrasives. This makes them suitable for high-traffic areas or environments where the coating is likely to encounter harsh conditions.
4. UV Resistance: Rust Bullet coatings have strong UV resistance, which helps prevent the coating from yellowing or degrading under sunlight. Some epoxy coatings may yellow or degrade when exposed to UV light unless they are specifically UV-resistant.
5. Flexibility: Rust Bullet coatings offer more flexibility compared to some epoxy coatings. This flexibility can be advantageous in environments where the concrete might expand or contract due to temperature changes or other factors.
6. Lower Maintenance: Due to the robustness and resistance to various elements, Rust Bullet Concrete coatings might require less maintenance over time compared to epoxy coatings, which can be prone to chipping or cracking in certain environments.
7. Versatility: Rust Bullet is versatile in terms of the types of surfaces it can be applied to, which includes not just concrete but also metal, wood, and other materials. This can be beneficial in projects that involve multiple types of surfaces.
8. Cure Time: Rust Bullet is fully cured at around 72 hours after the last coat is applied. Epoxy coatings generally take 7-10 days to fully cure, some even require force curing. Additionally, Rust Bullet can cure at temperatures as low as 32°F, which is advantageous during the winter months. Epoxy coatings require temperatures of about 50°F.

Like many surfaces, Rust Bullet Concrete coatings can become slippery when wet, and the necessity of a non-skid additive will depend on several factors:

1. 1. Location and Use of the Area: If the concrete floor is in an area prone to wet conditions, such as near swimming pools, in bathrooms, garages, or outdoor spaces, a non-skid additive can enhance safety by reducing the risk of slips and falls.
   2. Traffic Type: High-traffic areas, especially where people might be moving quickly or carrying heavy items, would benefit from a non-skid surface for added safety.
   3. Local Regulations and Standards: Certain industries or public access buildings may have regulations requiring non-skid surfaces for safety reasons.

1. Personal Preference: For residential spaces, the decision may also hinge on personal preference regarding the floor’s texture and appearance.

Rust Bullet recommends the use of Tread-Tex as a compatible additive to combine on your final coat for a non-skid finish.

NOTE: While non-skid additives improve safety, they can also change the floor’s texture and might require different cleaning methods. Non-skid additives can also reduce the sheen of the gloss coating to some degree.

•Do not power wash the surface to be coated. Rust Bullet coatings are moisture sensitive. Rule of thumb is for every inch of slab; it takes 30 days for the concrete to dry., i.e. for a 3-inch slab, that would be 90 days to dry completely. If there is moisture left behind, there will be adhesion issues.
• Rust Bullet coatings are moisture cured urethanes, so it’s important that your surface is COMPLETELY dry prior to application to avoid potential adhesion issues. Test to see if your concrete is still holding moisture by doing a simple moisture test; take a piece of plastic (one side cut off a gallon Ziplock bag works great) and tape it to the floor on all edges, making sure it’s sealed on all sides. Wait 24 hours and inspect to see if there is condensation or darkening of the concrete. Do this in a few places, going from the outside edges to middle of the floor to ensure it is dry throughout. If it darkens, it is still too wet to coat.
• Rust Bullet coatings only require a concrete surface profile equivalent to about 120 grit sandpaper. Frequently with new concrete, it will be power troweled or sometimes even coated with a sealer. If it was power troweled, it will likely require sanding the floor to create the necessary profile to ensure a good adhesion. If a sealer was used, remove this sealer to ensure a strong adhesion and prevent potential adhesion failure. Test to see if the floor has a sufficient profile by pouring just 1oz of water on the floor. See how fast it is absorbed. If it soaks into the floor within the first 30 seconds, this is a good indication that there is a profile for adhesion. If the water beads up on the surface and is not absorbed within thirty seconds, create the profile by sanding the floor with 80-100 grit sandpaper. This can be done using various methods, from stand-up orbital sander to a manual pole sander.
• Remove dirt, dust, etc., with an air hose, vacuum, broom etc. Rust Bullet is moisture sensitive. Spot treat oil or grease spots with a light detergent such as Dawn dish soap and water or Simple Green. Allow it to dry completely before applying any Rust Bullet coating.
• Do not open the can of the Rust Bullet until you are ready to start your project. Pour out what’s needed and close the lid to keep air away from the remaining coating. Rust Bullet coatings have phenomenal adhesion so clean any paint from the rim before replacing the lid to reopen the lid.
 • Use a 3/8-inch nap roller for the best coverage. Do not use foam as foam tends to slide the coating around as opposed to achieving a thin, even coat. Microfiber rollers will give the smoothest coverage. The main goal here is to achieve thin, even coats.
• Start with small 4’x4′ sections at a time. This will ensure the areas are covered evenly.
• Do your edging first. A paint brush may be used for the edging.
• Dip the roller into the roller pan several times during application to keep a wet edge. Keep in mind to not have too much paint on the roller. When the roller slides, that means it is not coating, and proper coverage will not be achieved.
• Rolling a pattern with a medium amount of pressure on the roller handle to achieve the best coverage.
• Thin even coats are best! Do not assume that applying Rust Bullet in thick coats will provide better protection. It will not. In fact, if Rust Bullet is applied too thick, solvent popping occurs, and the coating will not cure properly. Again, thin, even coats.
• Seeing roller marks? When using Rust Bullet as a concrete floor coating, the roller marks generally appear because the thickness of the coating is not even throughout. When rolling each section, watch the already coated sections for those roller marks. If they start to appear, take the roller without adding more paint, and with no pressure on the roller handle, roll over the coated surface to even the coat out.
• Even though the roller is the most common method of application, Rust Bullet can also be brushed or sprayed. If spraying, we recommend an Airless sprayer with a 517-523 tip, 3000-5000 psi.
• Remember that all Rust Bullet requires a minimum of two coats, and the recoat time frame of approximately 2 to 6 hours between coats must be followed.
• If more than 12 hours have passed since the last coat of Rust Bullet, wait for the paint to cure for 24 hours. Scuff up the surface with 80 – 100 grit sandpaper to create a profile for adhesion and apply it to the next coat.

When spraying Rust Bullet Automotive or Rust Bullet topcoats, the following recommendations should be followed for optimal results:

• • Spray Gun Type: HVLP (High Volume Low Pressure)

• • Nozzle Size: For HVLP, a nozzle size of 1.7mm to 2.0mm is recommended.

• • Equipment Preparation: Run Rust Bullet Solvent through the spray equipment prior to spraying to remove any moisture that may be trapped in the equipment.

• • Mixing: Stir the Rust Bullet coating thoroughly by hand before application. Do not thin the product unless necessary; if thinning is required, use no more than 5% Rust Bullet Solvent.

• • Surface Preparation: Ensure the surface is clean, dry, and free of loose rust and paint, oil, grease, and other contaminants. Sand or blast the surface to create a rough profile if necessary. Metal Blast will also clean and condition a metal surface for application.

• • Coat Thickness:
    
    • • Automotive Coating: Apply 2 to 3 coats to achieve a total dry film thickness of approx. 6 mils.
    
    
    • Topcoat: Apply 1 to 2 coats, aiming for a total dry film thickness of 2 to 4 mils.
  • Spraying Technique:
    
    • • Maintain a consistent distance from the surface (6-10 inches).
    
    
    • • Apply in even, overlapping strokes to ensure uniform coverage.
    
    
    • • Avoid heavy application to prevent runs and sags.
  • Temperature: Ideal temperatures to apply are between 50°F and 90°F (10°C to 32°C). Rust Bullet can be applied in temperatures ranging from 35°F to 110°F (2°C to 43°C).

• • Humidity: Ideal humidity levels are between 40% and 70%. Avoid application if humidity exceeds 85%.

• • Maintenance: After the application of each coat of Rust Bullet, flush the gun or submerge the tip in Rust Bullet Solvent. It is important to keep the equipment and sprayer clean. If the spray gun has a filter, it must also be cleaned.

• Safety: Wear appropriate personal protective equipment (PPE) such as gloves, goggles, and an organic vapor respirator. Be sure to allow adequate ventilation during application and drying.

Following these guidelines will help achieve a durable and high-quality finish with Rust Bullet Automotive and any Rust Bullet topcoat product. For additional details about application, please refer to Rust Bullet’s application and technical documents.

NOTE: If Rust Bullet Solvent is unavailable in your area, Xylene, Toluene or MEK may be substituted.

Yes, you can apply a truck bed liner on top of Rust Bullet. Rust Bullet is a high-performance, industrial-grade protective coating that can serve as an excellent base layer for additional coatings, including truck bed liners.

Apply the minimum two coat application of Rust Bullet and allow it to fully cure, then scuff the surface with 80-100 grit sandpaper to provide a profile and ensure good adhesion of the truck bed liner. Check compatibility to ensure the bed liner is suitable for use with Rust Bullet.

No. After curing, all Rust Bullet coatings have a service temperature range of 314°F (157°C) continuous and can tolerate maximum temperatures between 617°F (325°C) and 662°F (350°C) for up to 72-hour periods. Rust Bullet provides excellent protection for most engine components; however, is not recommended for coating exhaust systems due to the excessive heat produced on headers, exhaust manifolds, catalytic converter, or exhaust pipes.

Yes, Rust Bullet is an excellent choice for undercoating your vehicle. Its advanced formulation provides superior protection against rust and corrosion, making it ideal for the harsh conditions faced by a vehicle’s undercarriage. Unlike traditional coatings, Rust Bullet creates a seamless, non-porous barrier that effectively seals out moisture, salt, and other corrosive elements. This ensures long-lasting durability and extends the lifespan of your vehicle.

Additionally, Rust Bullet is easy to apply and dries quickly, allowing for efficient application and minimal downtime. Its self-leveling properties ensure even coverage, eliminating the risk of missed spots that could lead to rust formation. With Rust Bullet, you can confidently protect your vehicle’s undercarriage from the damaging effects of road debris, chemicals, and environmental exposure.

For the best results, the surface should be coated with a high-build sand-able primer prior to applying the desired automotive finish paint. Always follow the recommendations of the manufacturer of primers, sealers, and finish paints for a proper application. Once a Rust Bullet coating has dried for at least 24 hours, a primer may be applied directly to the Rust Bullet coating after scuffing with 80-100 grit sandpaper.

For automotive projects, Rust Bullet is best applied using a High Volume Low Pressure (HVLP) sprayer, which can provide a smooth and even application. It is recommended spray applications are done by experienced users to ensure a successful application. Here are the recommendations for using Rust Bullet with an HVLP sprayer:

• • Rust Bullet’s high solids content requires a robust sprayer capable of handling thicker materials. A nozzle size of 1.7mm to 2.0mm is generally recommended. This size allows for efficient spraying of the coating without clogging.

• • Stir the Rust Bullet coating thoroughly before use to ensure even distribution of the solids. Stir by hand until homogenous, approximately 3 minutes. Avoid whipping air into the coating and do not use mechanical means to mix.

• • Rust Bullet coatings are ready to use right from the can. Thin only with Rust Bullet Solvent when necessary, not to exceed 5%. Do not over-thin, as this can affect the coating’s performance.

• • Perform a test spray on a piece of cardboard or a similar surface to adjust the sprayer settings and ensure a smooth, even spray pattern.

• • Prior to spraying, run Rust Bullet Solvent through the spray equipment to remove any moisture trapped in the sprayer. Flush Rust Bullet Solvent through pump, line, and gun to remove any existing moisture or alcohol from previous coatings or solvents.

• • After each coat of Rust Bullet is applied, flush the gun, or submerge the tip in Rust Bullet Solvent.

• • Application equipment and filters must be cleaned after use to avoid damage to the sprayer. Any remaining Rust Bullet coating will cure and likely destroy the equipment.

• • When the spray gun is not in use, such as between coats, it should be completely submerged in a container of solvent.

• • Straining through a nylon bag strainer is recommended.

• • Inspect all spray equipment to ensure it is clean and in good working order prior to application.

• • Do not re-circulate the Rust Bullet Solvent through the pump, as the Solvent will be contaminated with moisture and debris.

• • Apply Rust Bullet in multiple thin coats rather than one thick coat. This helps to achieve an even application and better curing.

• • Overspray is unavoidable with a spray application; however, most sprayers now have adjustable pressure control to spray a wider range of materials with more control and reduced overspray.

• • Overspray is controlled by the operator and the choices made, such as tip size, tip condition, pressure, distance, angle of spray gun in relation to surface, wind, etc.

• • Any sprayer will produce some form of overspray, but there are two main ways to help reduce the overspray; a) set the pressure control at the lowest possible pressure, while still maintaining a solid fan pattern; b) ensure that the correct tip size is being used. Using a tip that is too large will only result in excess paint being applied to the surface.

• • Ensure that minimum cure times are followed before the application of a subsequent coat, approximately two to six hours.

Yes. Most body fillers, fiberglass and automotive primers may be applied directly over Rust Bullet. Two coats of Rust Bullet should be applied to the metal surface. The body filler, fiberglass or primer should be applied directly over the second coat of Rust Bullet between the time that the last coat of Rust Bullet is dry to the touch, about two to six hours, up to 12 hours. The previous coat should be dry to the touch and not wet or tacky; if there is no transfer of coating to a gloved finger it is safe to apply a filler. If 12 or more hours have lapsed, wait for Rust Bullet to cure for at least 24 hours then lightly scuff with 80-100 grit sandpaper; enough to break the glaze to create a surface profile. This 12-hour period is decreased in areas with high humidity levels.

NOTE: Fillers tend to absorb moisture which will cause further rusting of the metal and bubbling of the filler if applied directly to a rusted area that has not been protected with Rust Bullet. Rust Bullet works best when it is in direct contact with the metal.

Yes. Rust Bullet can be used as an automotive primer that will provide corrosion control and a durable barrier of protection. Before applying a finish color to a surface coated with Rust Bullet, we recommend applying a high-build, sand-able primer to the coated surface. Rust Bullet produces a very hard surface when cured; therefore, applying a sand-able primer to the final coat of Rust Bullet will accomplish two things: remove any imperfections in the coated surface and provide a surface that is easier to sand smooth. It will also allow you the luxury of applying the final color whenever you choose to do so. Many body shops use this method to save time and work. Always follow the manufacturer’s recommendations.

No. Rust Bullet is not affected by gas but was not designed as a small engine tank sealer on the inside of a small engine gasoline tank. We have not tested this application and can offer no promise as to what the outcome will be if used as such. Rust Bullet can be used on the exterior, but it was not designed for internal use on a small engine gas tank. There is no guarantee the inside of the tank is covered evenly or thoroughly. The inside of the tank does not receive proper air circulation for the coating to cure properly.

Rust Bullet does pass the Environmental Protection Agency (EPA) Standards for Potable Water; however, Rust Bullet has not been approved as a coating for containers for food or water consumption by the Food and Drug Administration (FDA). Until Rust Bullet has obtained certification from the FDA for use on surfaces that meet food, drinking water or food service equipment, we cannot recommend Rust Bullet products be used in that capacity.

Yes, Rust Bullet Industrial can be used on wrought iron fencing, furniture, and fixtures. Rust Bullet is a versatile rust-inhibitive coating that provides excellent protection against corrosion and rust on a variety of metal surfaces, including wrought iron.

Yes. Rust Bullet Industrial will provide superior protection from corrosion and abrasives to chain-link fencing, adding years of life to the integrity of the steel.

Yes. Rust Bullet is currently used by many divisions of the United States Military. Rust Bullet has strong resistance to chemicals and abrasives in addition to its superior, patent awarded technologies for controlling rust and corrosion. Based upon the attributes of a properly applied and cured Rust Bullet coating, it may be used as a chemical agent resistant paint system.

Rust Bullet Industrial can be easily top coated with the Rust Bullet BlackShell, WhiteShell, or DuraGrade Color, as well as other standard military topcoat paints. Rust Bullet has been awarded a Schedule Contract with the General Services Administration (GSA), allowing qualifying entities to purchase from the GSA Schedule.

• The National Radio Astronomy Observatory’s Very Large Array (VLA)

Yes, Rust Bullet is compatible with cadmium. Cadmium is mostly used in the electroplating of metal and steel. It is used as a form of corrosion protection. Before applying Rust Bullet on electroplated surfaces, the surface must be clean and free of contamination. We recommend cleaning and etching the electroplated surface with Rust Bullet Metal Blast to ensure proper adhesion.

Rust Bullet is a protective coating designed to provide superior corrosion resistance. However, exposure to chemicals like fertilizers and lime can affect any coating over time. Here’s a general idea of how these substances might interact with Rust Bullet:

1. Fertilizers: Many fertilizers contain chemicals such as ammonium nitrate, potassium chloride, and urea, which can be corrosive. Continuous exposure to these chemicals might degrade the coating, especially if the fertilizer is highly acidic or alkaline.
2. Lime: Lime (calcium carbonate or calcium hydroxide) is less likely to be as aggressive as some fertilizers, but it can still affect the coating over time, particularly if it is frequently in contact with the coated surface.

If the coated surface will be frequently exposed to these harsh chemicals, it is recommended to apply an additional topcoat for added protection. A properly applied and cured Rust Bullet coating (Rust Bullet Industrial) with a DuraGrade Clear topcoat will hold up extremely well to fertilizer and lime. For the best results, apply thin even coats of Rust Bullet Industrial to achieve the minimum dry film thickness (DFT) of 12 mils (four coats) and two to three coats of DuraGrade Clear as a topcoat. A regularly scheduled inspection and maintenance program is recommended for all harsh environments, allowing for immediate identification and repair of any breaches or imperfections in the coating.

Yes. Rust Bullet provides excellent protection for an air duct system. We recommend not running air through the system for at least 72 hours after the final coat of Rust Bullet has been applied. Rust Bullet will encapsulate the rusted areas adding strength to the coated surfaces.

Yes. Rust Bullet protects metal from direct contact with magnesium chloride. Magnesium chloride is used as a deicer on roads in many states. It is very corrosive and will cause significant damage to concrete and metal. A very high concentration of magnesium chloride on a frequent basis will reduce the protective properties of any corrosion control coating, including Rust Bullet. Rust Bullet with its armor-tuff coating will last longer and provide better protection than any other product available. A dry film thickness (DFT) of 12 -15 mils or four to five coats is recommended for surfaces exposed to magnesium chloride. Regular inspection of the surface to identify breaches in the coating for immediate and easy repair is recommended.

The recommended application method for Rust Bullet on galvanized corrugated roof projects is an airless spray system with a 517 to 523 tip at approximately 3000-5000 PSI. Multiple coats should be applied to achieve the recommended DFT (dry film thickness); each coat of Rust Bullet will add strength and durability, increasing the life of the roof.

Yes. Rust Bullet is the ideal coating for protecting galvanized metal buildings and roofs. It not only provides protection from rust and corrosion but will make your metal roof stronger and more weather resistant. Following the application guidelines, application of Rust Bullet coatings to a clean galvanized surface will exhibit no issues with adhesion or compatibility. Rust Bullet applies easily and quickly by brush, roller, or an airless spray system. Costly roof and building replacements can be avoided by simply applying Rust Bullet.

An epoxy primer is not an anti-corrosive coating and will not furnish the protection provided by urethanes such as Rust Bullet coatings. Urethane coatings provide a high degree of chemical and moisture resistance as well as excellent adhesive properties. Additionally Rust Bullet products have demonstrated high competition with epoxy coatings due to the ease of application, one-component product, and ease of repair, when necessary. A properly applied and cured Rust Bullet coating will not break like the epoxy and powder coatings. Although Rust Bullet coatings do not require a catalyst for curing like the Epoxy coatings, using the Rust Bullet Rapid Fire Accelerator will decrease curing time by up to 80%.

If an epoxy finish is desired, and the existing surface is an epoxy finish, scrape off any loose rust and epoxy coating, rough-up the remaining epoxy with 80-100 grit sandpaper prior to applying Rust Bullet, then re-apply the epoxy coating over the final coat of Rust Bullet.

NOTE: For best results, the surface should be prepared down to bare metal, removing as much of the existing failing coating as possible. Rust Bullet works best when it is in direct contact with rusted or clean metal.

Yes. Rust Bullet Industrial is appropriate for most industrial or commercial type projects. A minimum dry film thickness (DFT) of 12 mils is recommended for most industrial and commercial applications.
Rust Bullet provides superior protection even under the harshest conditions common in industrial and commercial environments. It protects surfaces with an impenetrable, nonporous, armor-like shield that repair, defends, and maintains surface integrity. Rust Bullet Industrial received two United States patents for its technology in rust prevention and protection. Rust Bullet is UV resistant, scratch, chip and chemical resistant and provides outstanding protection from abrasives and corrosives that damage and destroy surfaces.

Rust Bullet is a one-part, multiple coat urethane that can be applied with little or no surface preparation, reducing the high cost of product, labor, and the containment of waste. Rust Bullet requires little or no maintenance, consequently saving money and minimizing down time. If surface preparation is necessary, Rust Bullet Metal Blast can be used to dissolve rust and properly etch the metal prior to the application of Rust Bullet. Always allow the surface to completely dry before applying Rust Bullet. Although it is not always necessary to blast surfaces prior to a Rust Bullet application, soda blasting, dry ice blasting and hydro-blasting are three methods of media blasting that are effective, clean, and environmentally safe. All media are sound options and clean-up will be relatively minor. Surface prep on industrial and commercial projects may vary dependent upon the condition of the substrate.

Yes. Rust Bullet can be applied directly to the clean surface of an aluminum hull. Etching the aluminum surface with Rust Bullet Metal Blast prior to the application of Rust Bullet is recommended for optimal adhesion.

Rust Bullet provides durable surface protection that is scratch, chip, chemical and UV resistant. Anti-fouling bottom paints reduce or eliminate marine growth that develops on a boat’s underwater surface. Anti-fouling paints do this by using chemicals that slowly release to repel underwater aquatic life. Most anti-fouling paints require a chemical reaction with the surface to which it is applied for proper adhesion. If using anti-fouling paint, please refer to the FAQ regarding the use of a marine tie-coat. Always check with the anti-fouling paint’s manufacturer before applying an anti-fouling paint over Rust Bullet.

A marine tie-coat is a general-purpose chlorinated rubber type product used on metal surfaces and as a tie coat between different types of coatings to prevent galvanic corrosion. This versatile product can be used successfully above and below the waterline and over a variety of coatings as a tie coat. It is generally compatible with anti-fouling bottom paints and various types of topside finishes.

Rust Bullet contains aluminum flake, which effectively makes it an aluminum surface. As most anti-fouling paints contain copper, applying it directly onto a cured Rust Bullet coating would create an undesirable, dissimilar metal (galvanic) corrosion. This galvanic corrosion occurs when two dissimilar metals (in this case aluminum and copper) are in contact with each other in an electrolyte (salt water). Due to the distance between aluminum and copper in the galvanic series, a non-conducting insulator (e.g. rubber) should be placed between them or they must be isolated from the electrolyte. On an ocean-going vessel the isolation is not an option and therefore the tie-coat must be applied when using Rust Bullet with an anti-fouling paint.

A minimum 12 mil DFT (dry film thickness) is recommended for marine applications. Additional coats or mils may be needed for adequate protection dependent upon substrate and exposures. Sea temperatures vary, as does the salt content; these factors may also help determine the appropriate DFT.

Rust Bullet is formulated to provide excellent corrosion resistance, even in harsh marine environments. The coating forms a tough, durable barrier that protects the underlying metal from the corrosive effects of saltwater. When properly applied, Rust Bullet adheres strongly to the substrate and maintains its protective properties over time. It is designed to withstand the physical and chemical stresses associated with marine environments, including constant exposure to saltwater.

Refer to ASTM B117 Seawater Spray (Fog) Test Results and ASTM D870 Seawater Immersion Resistance Test Results for further technical and engineering data on saltwater exposures.

It is recommended that a minimum 12 mil DFT is achieved for any marine or industrial applications for optimum protection. Rust Bullet can be applied by brush, roller, or spray equipment. The application method used will determine the number coats that are needed to achieve a minimum DFT of 12 mils. When using a roller or airless sprayer, three to four coats of the Rust Bullet Industrial will generally achieve a DFT of approximately 12 mils. It is our experience that a brush application will generally achieve a 1.5 – 2 mils DFT per coat.

For a marine applications, surface preparation is crucial to ensure the effectiveness and longevity of Rust Bullet coatings. Here are the general recommendations for surface preparation:

Surface Preparation Steps

1. • Remove Contaminants: Thoroughly clean the surface to remove all dirt, grease, oil, salt, and other contaminants. Use a degreaser or Rust Bullet Metal Blast for best results.Clean the Surface:
   • Rinse: Rinse the surface with fresh water and allow it to dry completely.
2. Remove Rust and Loose Material:
   
   • • Mechanical Cleaning: Remove any loose rust, paint, or coatings using a wire brush, scraper, or mechanical tools. For heavily rusted areas, consider media blasting; soda blasting and dry ice blasting are two methods of media blasting that are effective, clean, and environmentally safe. Both media are sound options and clean-up will be relatively minor including the drying procedure after the dry ice blasting.
   
   
   • Hand Tools: For smaller areas or less severe rust, hand tools like wire brushes and sandpaper can be effective.
3. Surface Profiling:
   
   • • Create a Profile: Ensure the surface has a rough profile to enhance adhesion. Metal Blast will etch a metal surface and is an effective way to condition your surface for application.
   
   
   • • Surface Roughness: Aim for a surface roughness of 2 to 4 mils for optimal coating adhesion.
   
   
4. Remove Dust and Debris:
   
   • • Blow Off Dust: Use compressed air or a clean, dry cloth to remove all dust and debris from the surface.
   
   
   • Final Wipe: Perform a final wipe with a clean cloth dampened with Rust Bullet Solvent to ensure the surface is clean.

Specific Considerations for Marine Applications

• • Moisture: Ensure the surface is completely dry before application. Moisture can significantly affect the adhesion and curing process.

• • Salt Contamination: Marine environments often have salt contamination. It is crucial to remove all salts using a salt remover such as Chlor*Rid and by thoroughly washing with fresh water.

• Temperature: Apply Rust Bullet in recommended temperature ranges (between 50°F to 90°F) and avoid high humidity conditions during application and curing.

Maintenance

Regularly inspect the coated surface for signs of wear or damage and perform touch-ups as needed to maintain protection.

For detailed and specific instructions refer to Rust Bullet’s application guidelines and technical documents, or Contact Us for technical support.

Rust Bullet coatings can be applied by brush, roller, or spray equipment. An airless spray system using a 517 or a 523 tip at 3000-5000 PSI pressure is the suggested method for marine, industrial, or other commercial applications. A minimum dry film thickness (DFT) of 12 mils is recommended. It is recommended that before and after each coat of Rust Bullet is applied, the pump, lines, and sprayer be flushed with Rust Bullet Solvent. It is essential to keep the application equipment clean and the line free of any buildup of Rust Bullet product.
