She moved the coffee table outside and onto a drop cloth to protect the legs. The process was simple: Using a water spray bottle to wet the marble surface and a palm sander, she moved in small circles until polish was gone. She worked section by section until the entire surface was honed.
Since it was difficult to tell when the polish was off, she kept a wet cloth and dry towel on hand to wipe off the wet dust and dry the surface before tilting it in the sunlight.
For the beveled edges, I sanded them by hand using a small piece of sand paper and the spray bottle. It’s important to keep the surface wet, but it doesn’t need to be drenched.
