DESCRIPTION AND USES
Rust-Oleum Automotive Primer Surfacer is designed to improve adhesion of the final topcoat and enhance the finish color. When brush or spray applied, this high build, rust resistant, sandable primer will hide sanding scratches and fill uneven surfaces. This product must first be combined with an equal 1:1 part of Rust-Oleum 248877 Specialty Reducer before spray application. This all purpose primer is suitable for use on metal, fiberglass, and wood. Do not use of surfaces that will come into direct contact with heat or temperatures exceeding 350°F.
PRODUCT APPLICATION
READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING PROJECT
SURFACE PREPARATION
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.
APPLICATION
Use outdoors or in a well ventilated area such as an open garage. Apply when temperature is between 50-90ºF (10-32ºC) and humidity is below 85% to ensure proper drying. Avoid spray application in very windy and dusty conditions. Cover surrounding area to protect from spray mist.
Mix thoroughly to ensure any settled pigment is redispersed. Combine equal parts by volume of 1- part of Rust-Oleum Primer Surfacer with 1-part of Rust-Oleum Specialty 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 gallon of Primer thinned with Specialty Reducer will cover approximately 160-200 square feet on a smooth surface.
DRY & RECOAT
Dry and recoat times are based on 70ºF and 50% relative humidity. Allow more time at cooler temperatures. The first coat will dry to touch in 10-15 minutes. Apply a second coat after the first coat is dry to touch. Allow a minimum of 60-90 minutes before block.
CLEAN-UP
Clean tools and equipment with Rust-Oleum Specialty Reducer immediately after use. Clean dried product with Rust-Oleum® Specialty Reducer. Clean up overspray, drips, or spatters with Rust-Oleum Specialty Reducer IMMEDIATELY as dried product is very difficult to remove. Properly dispose of all soiled rags and protect unused product from freezing.
