Aluminum should be blasted with aluminum oxide or sand, and not with steel or metal grit.Excessive blasting may result in a warped or deformed surface. After blasting, wash aluminum with a commercially available aluminum cleaner. Allow to dry, then prime.
Brass and Copper: Brass and copper should be blasted with sand, and not with steel or metal grit. Remove all dust and grease prior to applying primer. Galvanized Surfaces: Clean and degrease any contaminated surfaces before priming. Do not blast galvanized surfaces with an abrasive grit. An adhesion test is recommended prior to starting the project.
Fiberglass Reinforced Plastic: The gel coat should be lightly blasted or sanded with 80 grit sandpaper and cleaned.
Plastic Foams: Enhanced adhesion is obtained when the foam is mechanically abraded. When coating polystyrene, do not use a solvent-based primer.
Textiles, Canvas, Fabrics: Adhesion to most fabrics, geothermal membranes and textiles does not require a primer. Stainless Steel:Stainless steel may be grit blasted and degreased before priming. Some stainless steel alloys are so inert that it is not possible to achieve a satisfactory bond. An adhesion test is recommended prior to starting the project.Also See: Surface Preparation, Stainless Steel, Industrial Coatings, Recommended Prior, Coatings, Steel, ResistanceTop Searches - Trending Searches - New Articles - Top Articles - Trending Articles - Featured Articles - Top Members
