The luster of marble and granite comes from the multi-step process of polishing. Polishing smaller pieces of marble or precious stone can be done by hand and achieved by using either a sanding block or palm sander. On a larger scale, industrial machinery is equipped with coarse “shoes” or sanding blocks and along with constant force and pressure, it can polish a huge slab with efficiency.
1. Begin my clearing the area you would like to clean. Spray the marble with water and be sure the surface area is completely wet prior to sanding.
2. Using a palm sander (or sanding block), attach a piece of 120-grit sandpaper on the pad.
3. Begin sanding the marble in a circular motion and apply a consistent amount of pressure. Once you have completed sanding the area, clean it off to remove any reside grains, and repeat the process with a 300-grit sandpaper, and follow it up with yet another session using 600-grit.
4. Wipe the marble with a damp sponge to remove dirt or any sanding dust.
5. Once dry, inspect the area you worked on. If you are happy with the results we suggest you seal your precious stone using oil-resistant sealers.
