Tips for painting an old kitchen countertop include cleaning it thoroughly, sanding it, filling any cracks, and applying primer before painting. Use acrylic enamel paint or epoxy or water-based latex paints, apply the paint using rollers, and apply a sealer if a water-based paint is used. Avoid painting on mineral and granite countertops.Continue Reading
Clean the kitchen countertop with trisodium phosphate, which removes grease, and rinse with fresh water. After cleaning, sand the area using 120- to 150-grit sandpaper to scuff it, vacuum the sanded dust, and wipe the surface with a moist cloth to remove any debris. Cleaning and sanding help the paint better adhere to the countertop.
Fill any cracks in the countertop with spackle to smooth the surface. Use a single coat of an alcohol-based shellac primer or a water-based acrylic primer. Apply the primer on the edges and difficult-to-access areas of the countertop. Allow the primer to dry for one day before applying paint.
Avoid using oil-based paints, as the countertop may come in contact with food. Instead, use water-based latex or epoxy paints. If using acrylic enamel paint, a primer coat is not required.
Use a roller rather than a paintbrush to apply paint to give the countertop a smooth finish. Apply two coats of the paint; allow the first coat to dry completely before applying the second one. Use several coats of polyurethane sealer to increase the lifespan of the paint.
Paints adhere well to wooden, formica and laminate countertops, rather than mineral and granite varieties.Learn more about Home Maintenance
