The goal is to remove the scratches without sanding deeply enough to remove the entire gel coat from the surface of the cultured marble. Keeping the sanding level prevents development of dips that might hold water.

It is recommended to remove any cultured marble sinks and other smaller pieces before beginning the process. Use water to keep the surface wet when sanding and rinse away any dust that forms during the polishing process. Be sure to dry thoroughly before proceeding.

The shine is restored by applying a second coat of buffing compound. Allow it to dry, and buff using an automotive buffer and pad. Once this process is complete, washing and drying removes any dust that forms. A dust mask protects the lungs from the dust due to the polishing process.

Upon completion of the process, the cultured marble is ready to reinstall. Owners should avoid using abrasive cleansers to prevent future scratches.
