The thin set will squish down to maybe 1 16 using the proper trowel you also need to factor in the thickness of the tile i used the regular ditra to match my 3 4 hardwood my tile was slightly thicker than usual i used a 3 4 notched trowel and also back buttered my tiles to give some extra height and of course to ensure good coverage contact.

Mortar single layer of plywood or osb joists i joists or trusses areas of application over any even and structurally sound osb or plywood subfloor with 16 406 mm o c.

This results in an integrated heating mat. In general we don t recommend the use of modified thin set mortars to set tile over the membranes because these mortars must air dry to cure properly. I will be installing ditra and wonder 1 if the thinset to install the ditra is sufficient as also the skim coat to protect the heat may.
