Can OSB plywood be used as an underlayment for ceramic tile floor? I have 5/8" existing plywood on 16" joists. I plan on adding another 5/8" OSB and 1/4" cement backer board to this. Will this work? Also how much spacing should I use between the sheets for expansion?
Thanks in advance.

Hi
OSB or particle board is the worst choice there is for ceramic tile...it just swells too much if it gets wet..including the moisture from the thin set. If your joists are 2x10 16" on center with 5/8 ply on top, then you can use 1/2 inch concrete board on top of it, and eliminate the second layer of plywood. The second layer of plywood would give you a stronger floor, but it may not be nessesary. Does you floor feel solid now, or is there some flexing when you walk on it, or if you jump up and down in the room?
