Sand the countertop thoroughly using an electric sander and medium-grit (80- to 100-grit) sandpaper. This step is essential. The paint will not adhere to an unsanded laminate or formica surface. (Painting stone granite, marble or other countertops is not recommended.)
Sweep up the dust and then run a damp cloth over the surface. Rinse the cloth and continue until you are certain all of the dust has been removed. Paint does not stick to dust.
Sand the primer lightly by hand using 220-grit sandpaper and clean up the dust as in Step 2. Roll on a high-quality paint and allow it to dry thoroughly. Sand lightly by hand with 220-grit sandpaper between coats. Apply two or three coats of paint until you have an evenly painted surface.
Decide whether you want a faux finish for the countertop. Several companies sell kits that provide the materials to make a faux granite surface. Or you can use any faux painting technique to apply glazes using rags or special rollers to give specific effects.
Roll on several layers of a high-quality clear protective top coat, sanding lightly between each coat.
Clean the existing countertop thoroughly with tri-sodium phosphate (TSP). Rinse and allow to dry for at least 24 hours.
Roll on a coat of primer as described in Step 2 above.
Apply a coat of epoxy finish following the manufacturer's instructions.
Roll on the protective finish following the manufacturer's directions. Allow the countertop to cure before using it.
