  1. Gather the supplies

    You need a variable-speed drill and a flexible round sanding pad. If you are using a stone grinder, you also need a special mounting base to attach the sanding pad. Silicon-carbide sanding paper is made for stone polishing, and you need it in numerous grits. You can also use diamond polishing pads, which come in even finer grits.

  2. Prepare the work area

    Since dry sanding creates dust, remove or cover any furniture or objects in the room. Wear a respirator and an eye mask to avoid ingesting silica dust, which is hazardous to your health.

  3. Sand the marble

    Use the 24 grit sandpaper to remove any scratches or grooves. Applying medium pressure, slide the drill over the surface of the stone. Keep the drill moving to avoid creating any indentations. The initial sanded surface is going to be rough, but it should be on an even plane. Continue sanding, working gradually from 24 grit sandpaper all the way up to 1,000 grit. Once sanding is complete, clean the surface with a wet cloth to remove the dust.
