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. If necessary, we recommend cleaning the surface with Rust Bullet Metal Blast. 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.
