Spots in black marble

I have a polished black marble bathroom floor (actually its called "triple brown" from Home Depot). Its been installed about 2 years and gets a lot of use. I am now getting whitish spots in certain areas, while others seem to be losing their shine. From your website, I gather that the whitish spots are actually etchings, and that it will probably be necessary to have the affected areas repolished with MB 11. If this is done, and corrects the problem, is there a recommended sealer to help keep it from happening again? Or should I just break out the affected areas and replace them? ( I do have an extra box or two left)

 

Dear Marc:

Had you simply reported me the problem about the etching I would have confirmed to you that MB-11 was the product to try, but you're also reporting severe wear and tear patterns. Under the circumstances, I would encourage you to hire a bona fide stone restoration contractor in your area to refinish your floor by slighty grinding (honing) its surface and then polishing it up back to factory specifications.

Now, you'd better watch out! I consider stone refinishing as the very pinnacle of all the activities related to stone from a professional point of view. Unfortunately, there are a lot of quacks on the loose out there! You get one of those, and you may even have to kiss your stone bye-bye!

How could you tell a champ from a chomp? Could you trust the recommendation of your local stone distributor, or contractor, or your interior decorator? Hardly!

We have available a very comprehensive article on how to select a bona fide stone restoration contractor, which will give you all the intelligence you need to make a competent choice. It does carry a small price tag, and you can order it by logging on the Educational Literature section 0f our website at:   http://www.mbstone.com/literature/literature.htm. It's available in pay-per-download format and I consider it a cheap “insurance premium” to pay when there are thousands of $ involved! Not to mention the little and much needed support you'd be giving to the cause – YOUR cause, since every single penny of the cost of the article will be used to support it.

About the “Magic sealer” that could prevent etching, it does not exist.
