Hi there. I've got a kitchen floor i grouted about 6 months ago, using polyblend (home depot's) sanded grout. it's about 1/16th" grout joints i think. fairly tight.
The tile is laid directly on a plywood subfloor, which i screwed the hell out of. Problem is, there is a creak in one spot. Enough that the grout is cracking up for a couple tile lengths.
Is Mapei a more flexible grout? what about epoxy mapei? any suggestions here? I don't think i can pull the tiles up and fix it from underneath. I was thinking maybe regrouting and grabbing a matching caulking for the spot that cracks up? Is there another product someone would recommend? i don't mind regrouting.
I'm picky for cleanliness, and i used what i assumed was the best sealer, sealed it 4 times, and it's still getting dirty.
Please help! its a small kitchen and a complete eyesore!!
