How to Apply Automotive Primer Surfacer
Bare Metal or Sound Rust Surfaces: Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and allow to thoroughly dry. Remove tar, dirt, grease, and oil with a solvent cleaner such as Rust-Oleum Wax & Tar Remover. Sand the entire surface to be painted with 120-220 grit sandpaper and then remove all sanding dust with a clean cloth or vacuum to ensure proper adhesion. Protect and mask-off all surrounding areas to prevent paint splatter and overspray.
Previously Painted/Coated Surfaces: Use a wire brush to remove any loose or peeling paint, rust or coatings so that the surface is clean and completely bare. To promote proper adhesion, completely scuff sand and feather edge the entire area to be painted with 120-220 grit sandpaper. Remove all sanding dust with a clean cloth or vacuum.
Mix thoroughly to ensure any settled pigment is re-dispersed. Combine equal parts by volume of 1- part of Rust-Oleum Primer Surfacer with 1-part of Rust-OleumSpecialty Reducer. If using a conventional spray gun, the air pressure should be adjusted to 30-40 pounds. Apply 2-3 medium coats and allow each coat to dry to touch before applying the next coats. Allow a minimum of 60-90 minutes dry time before block sanding with 320 grit sandpaper. Brush application of Rust-Oleum Primer Surfacer without reducer is recommended for touch-up application only. One quart of Primer thinned with Specialty Reducer will cover approximately 40-50 square feet on a smooth surface.
