All surfaces must be clean, free from loose or peeling paint, grease, oil, dirt, rust, mill scale and other contaminants. If this procedure is not observed, the drying and adhesion of any coating will be adversely affected.
Previously Painted Surfaces: Dull gloss areas by light sanding to enhance adhesion. If necessary, prime with Ronan Sticktite White or Prime-All.
Metal Surfaces: Remove loose rust and scale with a wire brush, steel wool and/or sandpaper. Any rust left on the surface could cause adhesion failure. All oil, grease and contamination must be removed. For best results, treat with a mild phosphoric acid solution. Acidic or alkaline surfaces should be neutralized. Prime with Ronan Universal Metal Primer.
Galvanized Metal and Aluminum: Surface should be wiped with solvent to remove oil and grease. A mild solution of phosphoric acid should be used for etching to ensure a good bond. If acids are not available slight surface sanding will be beneficial. Following sanding by priming with Ronan Universal Metal Primer.
Concrete: A white powdery deposit (efflorescence), often found on concrete and masonry surfaces should be completely removed with a stiff wire brush. New concrete should set four (4) to six (6) weeks before coating. All concrete surfaces should be etched with a solution of four (4) parts water to one (1) part muriatic acid. Let solution soak on surface for 15 minutes before rinsing with clean water. Allow 48 hours to dry before painting. Prime with Ronan Prime-All.
MDO Plywood: Clean surface to eliminate oil, grease and other contaminants. Prime face with Prime-All. All edges should be puttied and then primed with two coats of Ronan Prime-All.
Masonite: Clean surface to eliminate oil, grease and other contaminants. Prime with Prime-All.
Vinyl Surfaces: Pretreat by wiping with xylene or alcohol to help adhesion. Allow to dry completely before painting. Prime with Ronan Vinyl Cote. Note: Because of the many different types of vinyl on the market, it is recommended that each coating be tested on each type before using. To test apply the recommended primer and/or finish coat, let dry fully (8 hours). Apply a piece of tape to the coated area, then remove tape. If coating does not lift when tape is removed, then it is suitable for use for that type of vinyl.
Fiberglass, Glass, Ceramic, Other Glossy Surfaces: Solvent wipe to eliminate oil, grease, etc. Slight sanding of surface will be beneficial. Prime with Ronan Prime-All.
