OK. I put down the self leveling compound yesterday and it went
pretty well. I only needed the self leveling compound on 1/2 of the
room because the floor had dropped on one side. So the floor is half
compound and half plywood (2 layers). Do I put the ceramic tile
directly on the plywood/compound or do I need to put down backer board
first? If so, how would I attach the backer board to the compound
Your 1/4 backer board needs to be attached to 1 1/4" minimum of well secured
flooring. One inch usually works if the joists are 16" OC. It can be nailed
or screwed into place with one attacher in each of the dimples (hardiebacker
Laying up tile on a plywood substrate is an exercise in futility.
