There could be a couple of possible scenarios... One, there is efflorescence. Check for moisture in one of two ways. One, get moisture meter (www.moisturemeters.com) or another option for testing for moisture is to take a good sized piece of Saran Wrap and tape it over the area nice and tight. Wait 24 hours. If condensation appears, then you've got a moisture issue. If that's the case put a fan on it to dry it out.

Another possibility might be if there was an acrylic coating and the mat got wet under there it will turn the acrylic coating a milky coating. If that is the case, remove the coating use using a floor stripper or acetone. Put some on the area, agitate it and see what happens. If it looks like that is the problem you will want to strip the entire floor, then reseal and treat as needed.

Hi Guys!

We have a problem with a limestone floor. The original floor is gray/charcoal gray limestone with a pillowy surface--not honed. The floor was flooded and a carpet sat on the wet floor. The original surface not affected by the carpet is still dark but the 6 tiles that were under the carpet appear stripped and lighter. We cleaned and enhanced it but it did nothing. If it is etched we cannot hone it (we don't think). It also appears that something is on it more than it looks etched.

Any suggestions?

Thanks

Paula
