    Attach a 30-grit sanding pad to the angle grinder. You also need to purchase 60-grit, 100-grit, 220-grit, 320-grit and 600-grit sanding pads.

  2. Put on the safety equipment

    Put on the safety glasses, work gloves and dust mask to protect yourself from flying marble pieces and marble dust.

  3. Sand the marble

    Turn on the grinder. Gently press it to the marble's surface, and move it in a circular motion until you have polished the entire surface.

  4. Wipe off the dust

    Use a cloth to remove any marble dust from the surface.

  5. Switch the sand pads

    Remove the 30-grit sand pad, and replace it with a 60-grit sand pad.

  6. Sand the surface

    Repeat the sanding process with the 60-grit sand pad. Remember to sand in a circular motion.

  7. Repeat the process

    Repeat the sanding process with each sand pad, working your way up to the 600-grit pad for the highest polish. Remember to dust the surface after every round of polishing.
