The floor is on a cement slab, kitchen Dining room, entry and small bathroom. There is about 600 sf. It has been checked for moisture. There wasn&#39;t any. The homeowner said the discoloration started a few months after it was installed. The sealer supposedly has silicone in it. He did say it was sealed at different times in different sections. Any where from 3 days to 2 weeks. It was raining at the time of installation.<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">My client has a Limestone floor that was installed about a year ago.  Some of the stones are turning dark, others are not.  In some areas al the Limestone is turning dark.  The homeowner used Miracle Sealants 2 part poultice.  It required 5 applications and scrubbing to lighten the stones.  Honing did not lighten the stones.  The Limestone was sealed with 511 Porous Plus after it was installed.  There is a moisture barrier and the thinset used was white.  We are trying to figure out a way to clean and lighten the stone to its original color.  Miracle Sealants 2 part liquid poultice is very harsh and melts both blue and vinyl tape.  Any ideas would be appreciated.<span><font color="#888888"><br clear="all">
