Full Answer

  1. Clean the cultured marble

    Using warm, soapy water, wipe down the surface of the faux marble, and dry it with a cotton rag.

  2. Sand the surface

    With 150 grit sandpaper, lightly sand down the surface of the marble, and then wipe it clean with a damp cloth.

  3. Prime the surface

    Apply a high-quality acrylic primer on top of the cultured marble. Use a flash bond prime such as Bullseye 1-2-3, XIM Primer or Benjamin Moore Fresh Start. Allow the first coat of primer to dry, and then add a second coat.

  4. Paint the cultured marble

    Brush or spray on interior satin or semi-gloss latex paint, or use a specialty countertop spray paint. Let the first coat of paint dry, and then apply a second coat.

  5. Seal the paint finish

    Once the paint is dry, apply two coats of waterproof polyurethane sealant. To avoid damaging the finish, allow the acrylic seal to cure for two to three weeks before heavy use.
