The key to a successful coating is proper and thorough surface preparation. Surfaces to be coated must be free of dust, dirt, oil, grease, paints, glues, sealers, or any other contaminant that may serve as a bond breaker. They should also have a porous, textured profile comparable to 80-grit sandpaper or rougher. Popular methods of surface preparation include grinding with 20-30 grit metal diamond discs, shot blasting , or pressure washing with a turbo-tip in conjunction with Proline’s Dura-Clean and Dura-Etch products.
