Note: Coverage may vary with mortar consistency, angle at which the trowel is held, substrate flatness, etc. Part of the beauty of DITRA is that it’s easy to cut, and there’s no minimum size requirement. Since the matting is virtually incompressible within the tile assembly, the advantages of uncoupling are achieved without sacrificing point load distribution capabilities. It does not have to be uniformly covered. 2. The area between the cut-out squares is actually flexible, but the squares themselves are rock-solid. Made of polyethylene, DITRA will serve as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB. The thinset is also so thin (and absorbed by the fleece layer) that it isn’t displaced by foot traffic either.

Ditra is an uncoupling membrane and still has requirements for proper substrate in order for it to do as it is designed. Or maybe I am wrong altogether and DITRA set is magical and does not conform to the laws of physics like gravity and displacement (the most likely explanation). ft. is rated 4.4 out of 5 by 13.
