I used the premix thin-set mortar to lay 12x12 granite tiles and after 3 weeks, there is still a lot of moisture in the tiles. I applied a layer of Red Guard down first, but someone told me I was overly cautious and the moisture is trapped and could be there indefinitely. Grout has Not been applied yet. Am I screwed?
More or less. The good news is that you SHOULD be able to pull the pieces up complete. You might want to read the following thread from several years ago. Premixed thinset is no good for the use it was intended, that being the replacement of conventional portland cement based thinset.
The granite has lightened in some spots over time. I brought in a dehumidifier I think helped a bit, bringing humidity down to 40%, but by the time I shut the machine off a couple days later, it got up to 110 degrees in the small bathroom. If I’m patient and don’t grout the lines, will it eventually all dry out…even if it’s a number of months later? I’m here for a while and can put up with it and no grout if I have hope it will eventually dry though the sides of the tiles (and a little through the polished top). I'm in the San Diego area if that helps at all. What's your latest thought?
it's best to remove tile and clean them and go back install them with flex based thing set. pre mixed and mastic for wall tile is same thing not good idea for use on floor it bouth are the same it will never dry special if moisture got to it when you were doing the installation. leave and learn they say. good luck by Floors We Do Floors We Do.
