Wet Sanding Cultured Marble

This is the same material that s used with fiberglass and it buffs out.

Wet sanding cultured marble.

While this method will work fine for statues tile and marble countertops sanding large areas of marble like marble floors requires a completely different process and technique. If the cultured marble surface still isn t smooth and shiny try wet sanding with 1 000 grit wet dry sandpaper also available at auto supply stores followed by buffing with rubbing and polishing compounds to remove any scratches from the sandpaper. Keep the sanding even level and straight. Change your damp pieces of sandpaper as required.

Cultured tops are made of polyester resin with a clear topcoat called the gel coat. Dampen a piece of 400 grit sandpaper and beginning again at one end evenly sand the entire cultured marble vanity surface as you did before. This will require using a wet sanding process to achieve the desired results. This diy project shows how we saved all the cultured marble countertops in our project house by polishing polishing polishing.

Sanding marble is a time consuming process. With a little elbow grease. Wipe your vanity surface again with a clean soft cloth.
