How can I renew my cultured marble countertops?

26 January 2013

Cultured marble is made from powdered marble that has been cast in polymer and covered in a gel coat. Marble alone is very porous and would stain easily if installed alone. With every day use, the gel coat loses a little shine and surface scratches reduce the luster of cultured marble.

Restoring the life to your cultured marble takes some finesse and patience. You will need an electric buffer with a 1” thick wool buffing pad and a solid polishing compound. Be careful that you do not use a buffer with more than 1800-2300 RPM’s; a higher powered buffer will burn the cultured marble. We suggest a solid polishing compound over a liquid product. The solid will turn to dust when used, but dust is easier to clean up than the splashy mess that a liquid compound creates.
