I just got done remodeling my kitchen and I am currently having a 12 x12 Travertine tile floor installed. I noticed the Tile Contractor did not use any thin set between the plywood subfloor and wonderboard. It was my understanding you nail/screw it down into a bed of thinset. Will this cause the floor to fail, should I have the contractor ripe up the WonderBoard and reapply it with thinset underneath it.
Thanks in advance for you help
