Subfloor Directly On Perimeter Wall Tiling

In my experience tile applied directly to plywood will be a short lived installation and more likely to encourage rot in areas near a tub or shower.

Subfloor directly on perimeter wall tiling.

Check for dips in the floor by sliding a 4 foot to 6 foot straight edge in different directions all around the room. Rogeraugust 21 2015 at 4 58 pm. It is a good idea to put half inch plywood underlay to strengthen the floor before using modified thin set to put the tile directly on wood. One advantage of this method is that it allows the installer to accommodate small flaws and unevenness in the subfloor.

The subfloor is 5 8 t g. Because most old homes only use 1 2 plywood or osb. Then install the wall tile 3 6 subway leaving a gap of 1 8 grout line width and caulking. Most of the cabinets are on the perimeter on the room with a peninsula that runs to the center of the room 7 from the outside wall.

If you find hollows and valleys you must fill them with a self leveling underlayment. We are planning on using ceramic tile with granite counter tops. It can also account for the gap or overlap between tiles. Fill seams in the subfloor with caulk.

I plan on installing the floor tile small mosaic first with a perimeter gap un caulked. The layer of mortar usually has a wire mesh reinforcement embedded in it. A successful tile installation project requires a level surface. I think the wall tile over the floor tile will look the best and hide the movement joint the best since it is on the wall and not the floor.

When the tile installer enters the room and is ready to begin working the subfloor must be completely flat and clean and all mortar used to install the underlayment must be dry. I have visited several tile stores and received conflicting subfloor thickness requirements. Once very common mortar bed installations involve pouring a thin layer of cement mortar and embedding the ceramic tile directly into it. This free tile calculator estimates the total number of tiles needed to cover an area such as a floor wall or roof.

I ll either use 1 4 inch cement backerboard or a proprietary product like schluter ditra. It s usually a good idea to vacuum the floor just prior to spreading the thinset for the tiles.
