Plywood’s got moves—this expansion and contraction puts your tile installation at risk. Instead, choose a stable cement board for your subfloor.
When it comes to installing tile, what is the best underlayment? In the old days, they just went over plywood. But there's a reason not to do that: Your tile is more prone to cracking.
Remember, plywood is still wood. Wood expands and contracts. That movement breaks the bond between the tile and the subfloor and cracks the mortar.
So remember, the best subfloor choice for ceramic and porcelain tile is not plywood. It's cement board. It's Durock, it's HardieBacker—any product like that is a rigid cement board made for tile installation.
