How can Rust Bullet Coatings be applied?
Brush – Regular bristle brushes. Do not use foam! Use cheaper type of brushes, as you will need to discard of the brush when finished. A brush application achieves approx. 1.5 to 2 mils per coat.
Roller – Use a 3/8 inch nap roller. Do not use a foam roller. A roll application achieves approx. 1.5 to 2 mils per coat.
Note: Rust Bullet for Concrete can be sprayed with an Airless sprayer, and applied by brush or a roller. Clear Coat for Concrete cannot be sprayed. It is applied by brush or roller only.
Airless: The Rust Bullet Standard and Rust Bullet for Concrete can be applied using airless spray equipment. A 517 to 523 tip at an approximate 2000 – 3000 psi is recommended and will give you about 3-4 mils per coat.
HVLP: The Rust Bullet Automotive may be applied with HVLP (High Volume, Low Pressure) spray equipment. Use a primer size tip, dependent upon the equipment and the psi this may range from a 1.7 to 2.0 tip at 40-60 psi. An HVLP application gives about 2-3 mils per coat.
Tips for a successful spray application:
- Rust Bullet Coatings are ready to use right from the can; thinning is not necessary, do not thin.
- Prior to spraying, run Rust Bullet Solvent through the spray equipment to remove any moisture that is trapped in the sprayer.
- 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.
- Follow Stirring Instructions thoroughly before application.
- Inspect all spray equipment and ensure it is clean and in good working order prior to application.
- Flush Rust Bullet Solvent through pump, line and gun to remove any existing moisture or alcohol from previous coatings or solvents.
- Do not re-circulate the Rust Bullet Solvent through the pump, as the Solvent will be contaminated with moisture and debris.
- 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 your 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.
NOTE: If Rust Bullet Solvent is unavailable, xylene, toluene or acetone may be substituted.
