thin set dry time requirements
I recently had ceramic tile installed on 2 bathroom floors and tile tumbled stone backsplash in kitchen (2 days ago). I do not think the tile installers allowed the mortar to dry allotted time before grouting, as they were in hurry to finish. I am concerned as to what damage this may cause me in future. They used a thin set, powder mortar (they mixed) and sanded grout on all applications. I have not found any info on this problem. I am to seal the grout myself, but want to be careful that mortar and grout have thoroughly set. In some areas, they allowed 3 - 4 hours before applying grout, other areas, not even 1 - 2 hours. Please advise. Thank you.
