What size trowel for 12x24 floor tile over ditra.

Including 12 24 s 16 16 s 18 18 s 12 12 marble and granite and the popular 6 24 porcelain plank tiles. 15 inches and larger. I am setting 12 24 porcelain tile on a shower s walls and ceiling. I use this trowel size for any large format tiles.

If your floor is flat and your tiles are flat you might do well with a 1 4 x3 8th square notched trowel. The most common recommended trowel for this seems to be 1 2 x 1 2 square notch trowel but my test pieces show i am easily getting 100 coverage with a 1 4 x 3 8. If one of the tiles is fairly flat with minimum warping cupping you may meet the proper coverage requirement using a 3 8 square notched trowel. What trowel notch size is recommended for 12 24 floor tile.

1 2 x 1 2 square notch. If however the other tile has quite a bit of cupping you may need to use a larger 1 2 square notched tile trowel to get proper coverage. Tools and tips for the actual mortar application process for 12 24 tile as i mentioned before mix your mortar to be a little bit on the thick side and use a 1 2 inch notched trowel to apply it to the subfloor where you want your tile. With your 12 24 tiles you should use a 1 2 notched trowel on the wall and back butter each tile but just with a skim coat.

1 2 x 1 2 square notch. After determining correct trowel notch size based on tile type and size refer to the mortar coverage chart below in the thin set mortar technical data sheet or on the mortar packaging. Mix your thin set mortar to a fairly fluid consistency but still able to hold a notch and solidly embed the membrane into the fresh mortar with a float or screed trowel. How much thin set do i need to install tile over ditra or ditra heat.
