Burnt Marble Fireplace

by Nancy W.

QUESTION:

I have marble surrounding my fireplace and a hot ember landed on the marble and burned the marble surface. What can I used to restore the marble. It is a light green color. Many thanks!

ANSWER:

The solution depends on what type of finish you have on the marble... polished or honed.

If it's polished, I would really recommend hiring a marble restoration pro if you want the best results.

You can try some DIY options, but it will likely leave a blemish. Probably not as obvious as the burn, but unless the burn is very light it will be difficult to restore it to its previous condition.

If the marble is honed, then it is easier to handle on your own likely with satisfactory results.

First, whether honed or polished you'll need to clean the burned area as best you can using BLAST Mildew Remover... yes a mildew remover, but it works well for this purpose and won't further damage your marble like most other products will.

Spray on, let sit 5-10 minutes, scrub with soft-bristle brush.

For polished: use 0000 grade steel wool on the burn mark and see if you can get more off. Use BLAST some more, steel wool, BLAST, etc.

If this doesn't get it all, then you should call a pro if you want the to truly restore the area.


If you are willing to gamble a bit you can get more aggressive and follow the procedure....

For honed marble... and sand the area with 120, 240 or 400 grit metal sand paper until you remove all the burnt marble.

Start with the 400 and go to the more coarse grits if you need to go deeper.

NOTE: This will ruin the polish leaving a dull spot and slight depression. You may be able to get the shine back by sanding the area with 0000 steel wool until smooth and then using SCP- Marble Polishing Paste. But no guarantees on this... as I recommend... it's really a job for a professional.

On honed marble sanding will remove the burn and then you just sand the area with fine paper (400 grit) and then 0000 steel wool until it blends with the rest of the finish.

Good Luck,
