Is uncoupling membrane necessary over plywood?

Although some substrates absolutely require uncoupling membranes, they can be installed on a range of surfaces, including cement mortar, backerboard, OSB, and plywood. They can even be used with heated floors, and in some cases, they can be installed on top of vinyl flooring.

Can you put mortar on plywood?

Tip. Plywood and the flooring to which it is attached must be at least 1 1/8 inch thick to support the weight of thinset and tiles. Only exterior-approved plywood will support the weight; interior plywood and particleboard do not have the same strength and will buckle under the tiles.

How thick should plywood be for tile?

Use at least 1/2 in. underlayment-grade plywood, but I’d recommend 5/8 in. or ¾ in. plywood in your case as the stiffness of the framing is in question. Also you need to stiffen the plywood over the 24 in.

What is the proper subfloor for tile?

Exterior-Grade Plywood

Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
