Wet sanding cultured marble.

Sanding marble is a time consuming process. Dirt and dust will compress into the marble further scarring or discoloring the surface. With a little elbow grease. 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.

Change your damp pieces of sandpaper as required. Cultured tops are made of polyester resin with a clear topcoat called the gel coat. This diy project shows how we saved all the cultured marble countertops in our project house by polishing polishing polishing. 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.

Wipe your vanity surface again with a clean soft cloth. 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. 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.
