Choose a countertop color that will compliment the kitchen décor and color scheme.
Clean the countertop with a mild cleaning spray or a mild ammonia-based cleaner diluted with water. Dry countertop with a soft cloth.
Lightly sand the counter top with a 150-grit sandpaper. Sanding the counter top can smooth out any imperfections on the surface.
Prime the surface with 100 percent acrylic primer. Invest in a flash bond primer so that it can securely stick to the laminate. The flash primer will also allow the paint to stick more securely to the countertop's surface. Use a paint brush to evenly coat counter with primer, as directed on product label.
Allow the primer to dry for 30 minutes. Apply a second coat of primer. Allow the primer to set for 24 hours before applying color. Ventilate the area to allow the primer to dry faster and to remove toxic fumes from room.
Apply desired paint color enamel. Apply two or three thin layers of paint to the countertop's surface. Allow each layer to dry 30 minutes before recoating it.
Seal the paint with three coats of satin or high-gloss nonyellowing polyurethane to add durability to the countertop's surface. According to the New Homemaker, use a water-based sealer, so that it will not alter the paint's color when it dries. Allow the sealer to dry 24 hours.
