How to install ditra mat on plywood.

Subtracting the tile and ditra thickness leaves me with 3 8 left for thinset. Install the ditra heat mat one day and install the electric heat wire a different day. This is what creates the bond between the ditra mat and the plywood or o s b. This will allow the ditra mat to lay flat.

I want to install 12 porcelain tile with ditra on our foyer. Time to install the mat i grabbed the schluter ditra xl and carried it upstairs this was much easier than carrying up the 20 or so bags of concrete it would have taken for the other option the 175 sq ft roll of schluter pad we had weighed about 10 pounds. The problem is i only have enough room to install 1 4 ply over the existing subfloor. As mentioned when you have to pick a tile up and re install it you will have to do this more than once the suction of the tile can pull up the ditra mat causing it to break the bond to the plywood.

Will the thinset layers plywood ditra and ditra tile be 3 8 or less. I think i m going to be cutting it close but will be okay assuming that thinset raked with a 1 4 square notch trowel will wind up compressing to about 1 8 after setting the tile and a 1 4 v. The floor is 16 oc with a joist span of approx 65 with about half of it resting on the foundation. Step 4 embed the ditra mat into the thinset.

Again i think this is a bad idea. Lay the ditra mat on the thinset that you just troweled onto the substrate.
