A marble bathroom countertop is a great addition to any bathroom. Marble lasts longer than other materials, and it's natural appearance quite lovely. Every slab of marble is unique. No one else will have the same countertop as you. Eventually, the marble will wear. Follow these instructions to repair your marble bathroom countertop and restore it to its original beauty.

Step 1 - Clean the Countertop

Remove everything from the countertop and put it away for safekeeping. Add marble cleaner to your soft cloth. Thoroughly clean the marble, removing any stains, dirt, grime and grease. Dry it with a soft towel.

Step 2 - Apply a Glaze

If the marble only damaged on the surface with no deep gouges, use a simple marble glaze to refinish the small scratches. Apply the glaze with a small putty knife. Wipe off any excess. Glaze is available in a range colors for a perfect match.

Step 3 - Allow to Dry

Allow the marble to dry. Use a towel with some cleaner to shine the marble.

Step 4 - Sand the Marble Top

If your marble countertop has many scratches and gouges, you will need to complete a few extra steps in order to repair it. Wet the countertop thoroughly. Use a sander and 1000-grit sandpaper to sand the entire top. Start with the surface and sand until you remove all of the deep scratches. If the marble is cultured, do not go any further than the gel top coat. If the top is solid, continue to sand to repair deep gouges.

Step 5 - Rinse and Try

Use a dry towel and mild detergent to wash the marble. Rinse the surface with warm water and dry.

Step 6 - Buff the Top

Use a marble cleaner to completely buff the countertop. Apply a deep penetrating glaze and continue to buff until you have fully restored the marble. Wait until the surface has dried before replacing the countertop items.


If your countertop is made of cultured marble and cannot sand it because the gouges are too deep, fill them with silicone sealant or car wax. Add a cultured marble polish to finish the cultured marble.
