I am trying to figure out what went wrong. I had someone come about 2 weeks ago to regrout my master shower floor. He regrouted the tile as I had seen it done before by starting with scraping out the old grout, etc. The problem that I have is that the grout seems to have stopped drying (even with a fan blowing on it as suggested by the contractor) and there are areas of grout, sometimes 6 X 8 tiles that have a dark, almost wet looking grout (dry to the touch) and then there are areas where the grout has dried to the light bisque color.
The contractor has told me that there must have been water under the tile (new home!) and that the grout he installed is soaking up the water that was underneath. I was told to try drying the grout with a a hair dryer which has had little or no effect at all.
Any suggestions? I am totally frustrated and don't know what to do next. We aren't using the shower as we intended on sealing it, but now I don't know if this is from a bad grout mix or could he be right?
Thanks in advance for all of your help!
