Prepare countertops for painting by cleaning, sanding and priming the surface. Apply latex satin or semi-gloss enamel paint and finish with clear acrylic. Avoid scrubbing the surface until the paint has two to three weeks to cure.
Oil, grease, wax or accumulations of dirt on the countertop prevent the paint from adhering as it should. Clean the surface with warm water and soap. Rinse the laminate and dry it with a soft cloth. Use 150-grit sandpaper to sand the counter lightly and wipe away any dust from sanding.
Select a color that helps to coordinate the floor and walls in the room. Avoid trendy colors that are likely to be out of style quickly, unless you intend to replace the existing countertop within the next couple of years.
Choose a flash-bond primer that states on the label it is for gloss or high-gloss surfaces. Apply the first coat and follow the label directions for drying time before applying the second one. Once the primer is dry, apply two coats of acrylic paint. Avoid flat or eggshell paint that does not provide the hard finish needed for the countertop.
Apply the clear acrylic to the dry countertop. It should dry quickly but takes time to cure to its full hardness. Protect the counter during the curing time to ensure you have a long-lasting finish.
