Preparation for installing floor tile depends on the type of subfloor in the room you are tiling. A subfloor is the bottom most structural level of your floor. According to backer board manufacturers and tile setters installing backer board directly over an old solid. When you install your vinyl on a wood subfloor the top plywood should be a minimum of 1 4 thick.

In most cases as long as the old vinyl surface is flat you don t need to do anything more for this type of underlayment. However you re not out of the woods. Concrete and wood subfloors each have their own subfloor preparation. To do this measure and cut the plywood to fit your room.

Do not line up the second layer with joints in the first layer. The best method is to refasten the subfloor then add a layer of plywood.

Concrete expands and contracts and that type of movement can also crack the tiles and the grout.
