Wet Sanding Cultured Marble

This diy project shows how we saved all the cultured marble countertops in our project house by polishing polishing polishing.

Wet sanding cultured marble.

Before sanding or grinding any marble surface it is important to clean the area thoroughly. Wipe your vanity surface again with a clean soft cloth. 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. Keep the sanding even level and straight.

I was disappointed by how quickly my cultured marble countertop lost its shine so one day i took out my auto polisher and went at it. With a little elbow grease. This will require using a wet sanding process to achieve the desired results. This is the same material that s used with fiberglass and it buffs out.

Cultured tops are made of polyester resin with a clear topcoat called the gel coat. 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. Dirt and dust will compress into the marble further scarring or discoloring the surface.
