Remove 3/4 inch plywood (this was my contribution to the job!)
Evaluate and repair planking, squeaks and lose boards.
Lay backerboard 3/8 inch on top of planking
Lay the tile
Work is in progress as I type. I will send finished pics.
Why did they remove and not replace the 3/4" ply ?!?.. Or drop down to 1/2"?... I don't recall you telling us how thick the planks were any less then 3/4" won't prevent movement.
I take it you did 3/8 instead of 1/4" because you think this will prevent movement?
I don't see that they are using thinset mortar for the backerboard to be placed in?..... This makes me think that they won't tape the seams either
Which will make putting backer board down pointless if avoided both methods of cbu install.
