What is ditra matting.

It is made of polyethylene creating a waterproofing layer protecting the substrate. Ditra mat underlayment for tile is a tile backer that has some great benefits when installing tile over o s b. Thus ditra effectively manages moisture beneath the tile covering. The free space provides an escape route for excess moisture and vapor that could otherwise cause damage to the tile layer above.

Ditra matting is specifically designed for tile and natural stone installations. Or plywood sub floors. Vapor management the distinguishing feature of ditra is the existence of free space created by the configured channels on the underside of the matting. These cavities are filled with thin set mortar that produces a mechanical bond between the mortar and the tile.

Ditra is a polyethylene uncoupling underlayment with a grid ditra is an uncoupling membrane designed for ceramic and stone tile installations on floors. Ditra mat reduces the movement of the o s b. A test performed by the tca showed that using non modified thinset to mount porcelain tile to ditra achieved an average shear bond strength of 190 psi over the minimum spec of ansi 118 4 i make sure porcelain tile is back buttered before setting over ditra. From what i understand ditra is about 1 8 thick.

The short answer is that it s an underlayment used under tile and stone flooring to decouple the ceramic tiles from the subflooring which may be subject to expansion or deflection which can cause tiles or grout lines to crack. Being transferred to the tile. Subtracting the tile and ditra thickness leaves me with 3 8 left for thinset. The matting has a grid structure of square cavities which are each cut back in a dovetail configuration.

By isolating the tile from the wood floor beneath it eliminates cracking in the tile and grout joints. With a grid structure of square cavities. Ditra matting is a polyethylene membrane with an anchoring fleece laminated to its underside. It provides uncoupling to prevent cracked tile and grout.

This is especially important in. What the heck is ditra. The minimum height that my new dishwasher can be adjusted to is 33 3 4 and the cabinet height is 34 1 2. The schluter ditra matting is a flexible waterproof form of it.
