Continue Sanding: Gradually move up to finer grits, such as 180, 220, and 320, until the surface is completely smooth. Each grit level will remove finer scratches and imperfections.
-
Seal the Marble: Once the surface is smooth, apply a marble sealer according to the manufacturer’s instructions. This step is crucial for protecting the marble from stains and etching.
Common Mistakes to Avoid When Sanding Marble
While sanding marble, it is essential to avoid certain mistakes to ensure a successful outcome:
