How to Tile on a Wooden Floor

Old wooden subfloors and hardwood floors are both surfaces which homeowners may want to cover with the tile. Provided that both surfaces are in a good condition and level, it is likely to tile over them by the first screwing down the cement backerboard to make a smooth and level surface for the tiles to rest on. Direct tiling onto the wood is usually not recommended, because it can shrink and swell during humidity that can cause the tiles to come loose or crack.

• Lay down one by two inches thick cement backerboard all over the wood hardwood or subfloor. Cut the backerboard to fit the corners of the room through a carbide tipped scoring tool. Screwdown the backerboard to the wood by non-corrosive screws at every six inches.
• After this, apply fiberglass tape to every seam in the backerboard to shelter it. Trowel on a small layer of thinset mortar all over the fiberglass to strengthen it, and allow the mortar to dry overnight.
• Measure one of the furthest wall from the door by which you enter the room, and locate its center point.
• Then fit the tiles onto the floor without using mortar to locate the best layout for the room. Set the next tiles out to each side evenly. It will provide you a balanced installation with the cut tiles lining the corners of the room where they are less possibility to be seen as you enter the room.
• Cut any of the tile to fit the space on a tile wet saw. Spread thinset mortar all over the floor through the towel.
• Grout the installation through spreading grout all onto the tiles through a grout float.
• Clean the surface of the tiles by a damp grout sponge.
