Since DITRA is impervious, it does not deprive the mortar of its moisture. 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.

Wood Substrate: OSB, plywood and framing members should be covered with a material such as DITRA underlayment because wood is very susceptible to changes and to moisture. Wood expands and contracts with moisture and temperatures changes and flexes when bearing loads. These movements will damage tile and grout without the presence of a flexible, motion-absorbing material. Wood will also be damaged by water, something this polyethylene membrane prevents. DITRA can be installed over these wood subfloor systems:
