Marble Chip Repair

Homeowners install marble tiles on floors, walls, saddles over thresholds and countertops in kitchens and baths. Marble comes in a variety of colours, making it fit into many different decorating themes. Marble offers a durable surface, but it is not impervious to accidental damage. Heavy items dropped on the floor or countertop or a forceful impact to the wall can cause marble to chip. Marble is an expensive material and replacement is not always financially possible, but chips in marble surfaces are repairable.

  1. 1

    Wipe the recesses of the chip with an equal mixture of ammonia and water to remove grease, oils and dirt. Rinse with plain water and dry with a lint-free cloth.

  2. 2

    Apply low-tack masking tape as close to the edges of the chip as possible to protect the surface surrounding the damage.

  3. 3

    Mix two-part epoxy repair putty according to the manufacturer's instructions. Wear latex gloves when mixing and kneading repair putty between your fingers. Choose an epoxy repair putty in a colour that closely matches the existing marble.

  4. 4

    Press the putty into the chip with a flexible plastic putty knife or tongue depressor. Flatten the top of the repair putty so it sits flush with the existing surface. Use care so as not to touch the putty to the existing marble surface.

  5. 5

    Allow the epoxy repair putty to dry thoroughly, typically less than 30 minutes.

  6. 6

    Rub the surface of the repair with a wet micromesh sanding cloth to smooth it. Dry the surface with a lint-free rag.

  7. 7

    Remove the low-tack masking tape. Remove excess epoxy repair putty from the marble surface with a straight edge razor blade. Hold the blade at a severe angle so as not to scratch the marble. Carefully scrape the excess repair putty away.

  8. 8

    Apply marble sealer with an artist's paintbrush over the repair to blend it with the rest of the marble surface. Choose a sealer with the same level of gloss as the current surface.

Tips and warnings

  • Choose a marble repair kit when shopping for epoxy putty. Kits usually contain everything you will need to complete the repair.
  • If possible, bring a scrap piece of marble with you to help find a good match in terms of colour.
