The new tile floor in my kitchen with 14 inch tiles are clicking. We pulled up a few and reset with more mortar but more are clicking and I think a few of the originals.
I am afraid the subfloor (two 5/8" plywood sheets) moves too much. It has been suggested that I pull up the bad tiles and then screw the floor to the joists. Will this be sufficient? The floor does seem to move when my 250 lbs walks on it - the movement can not be seen from the basement - it is not the joists. Would additional cross bracing installed from below help? Would additional wood from below then screw up and pull down work (plywood does not hold screws well. I do have full access from below.
