Using a thin set mortar that is suitable for the substrate apply the thin set mortar mixed to a fairly fluid consistency but still able to hold a notch using a 1 4 x 3 16 6 mm x 5 mm or 5 16 x 5 16 8 mm x 8 mm v notched trowel. In general we don t recommend the use of modified thin set mortar to set tile over the membranes because these mortars must air dry to cure properly. Skip to primary sidebar.

Another reason would of course be too much deflection in the subfloor or bad prep. I don t see a scenario where ditra can be blamed for a tile failure.

Kerdi band must overlap ditra and ditra xl at seams and at floor wall transitions by a minimum of 2 50 mm in order to maintain waterproof integrity. Ditra can not cause a problem it can only prevent them. Skip to primary navigation. Skip to main content.
