The counter posed grains and strong inter sheet adhesive give this manufactured wood material its strength and resistance to warping. The short edges of the plywood must be centered over joists. Make sure the subfloor will not deteriorate when it gets wet. Plan the layout of the plywood sheets so the long dimension of the plywood runs perpendicular to the floor joists.

To be sure maybe drill up to 6 evenly spread out holes in the plywood at least 4mm deep or straight through in the areas to be tiled so the adhesive sinks into the holes and hardens hence creating a stronger fix. It s pretty easy when you know how. Cement backerboard is made for tiling. Plywood is made with layers of wood veneer laid with the grains at approximately right angles and then glued together.

The safest most prudent course is to install tile on top of a cement backerboard such as durock wonderboard or hardiebacker.
