Ditra Not Sticking To Floor

Thinset and sticking with ditra don t equate the only way ditra kerdi stata mat hydro ban sheet and any other fleece covered membrane designed to be applied with thinset relies on the thinset fully encasing and coating the fibers not sticking to them.

When installing heated tile floors with ditra heat mat or ditra heat tb there s two instructions that i would encourage you to avoid. In some applications the vertical section of the floor wall transition will not accept a bond to schluter set schluter all set schluter fast set or unmodified thin set mortar.

While ditra is my preferred membrane for floor tile installation as well as countertops and tub decks it absolutely needs to be installed correctly.

This allows the cement to properly hydrate resulting in a strong dense bond coat. 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. I don t see a scenario where ditra can be blamed for a tile failure.
