To paint laminate countertops, first thoroughly clean the surfaces, and sand them to allow primer and paint to adhere correctly. Once the paint is dry, seal the surfaces with an acrylic sealer, which will take two to three weeks to fully cure.
- Clean the surface
Wipe the surface of each countertop with soap and warm water.
- Fill any holes and sand the top
Use wood filler to fill in any holes and cracks. Once the filler is dry, sand the surfaces of the countertops with 150-grit sandpaper. Wipe away the resulting dust with a damp rag.
- Prime and paint the countertops
Apply a 100 percent acrylic primer to the countertops. Look for a primer designed to cover glossy surfaces. Allow the first coat to dry and then add a second coat. Let the primer cure for eight hours, preferably overnight. Paint the counter tops with a couple of coats of satin or semi-gloss latex enamel paint. Let each coat dry before applying the next.
- Seal the finish
Once the paint is dry, protect the finish by applying an glossy or satin acrylic sealer. Sealant takes two to three weeks to cure, so avoid touching or using the countertops during that time.
