Priming and Mixing. Before you mix your epoxy coating, apply an adhesion primer or promoter to the countertop with a sponge roller. Epoxy coatings require this coating to ensure a durable finish, but you can also use a primer labeled for use on shiny surfaces like laminate. Once the countertop is primed and dry, mix the epoxy coating, which is typically packaged in two parts: resin and hardener. Mix these immediately prior to application.
Red oxide primer is intended for use on interior and exterior ferrous metal and is not usually suitable for galvanized or nonferrous metals like aluminum, copper or brass. Ferrous refers to metals that contain iron.If youâre uncertain whether your metal is ferrous or nonferrous, use a magnet to test it.hen applying red oxide primer, use a brush or a short pile roller. Thinning is not normally required if applying with a brush or roller. If you use an airless sprayer to apply red oxide primer, thin the primer 10 to 15 percent by volume with acetone, xylene or synthetic reducer.
