What Is Ditra Matting

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.

What is ditra matting. Ditra matting is a polyethylene membrane with an anchoring fleece laminated to its underside. Vapor management the distinguishing feature of ditra is the existence of free space created by the configured channels on the underside of the matting. So it looks like i ve got 3 4 in which i need to fit the ditra tile and thinset. What the heck is ditra.

The free space provides a route for excess moisture and vapor to escape from the substrate that could otherwise cause damage to the tile layer above. 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. Ditra mat underlayment for tile is a tile backer that has some great benefits when installing tile over o s b. With a grid structure of square cavities.

Ditra matting is specifically designed for tile and natural stone installations. This is especially important in. Or plywood sub floors. Ditra is a polyethylene uncoupling underlayment with a grid ditra is an uncoupling membrane designed for ceramic and stone tile installations on floors.

Being transferred to the tile. From what i understand ditra is about 1 8 thick. It provides uncoupling to prevent cracked tile and grout. It is made of polyethylene creating a waterproofing layer protecting the substrate.

The minimum height that my new dishwasher can be adjusted to is 33 3 4 and the cabinet height is 34 1 2. The distinguishing feature of ditra is the existence of free space created by the configured channels on the underside of the matting. The free space provides an escape route for excess moisture and vapor that could otherwise cause damage to the tile layer above. Ditra mat reduces the movement of the o s b.

Subtracting the tile and ditra thickness leaves me with 3 8 left for thinset. By isolating the tile from the wood floor beneath it eliminates cracking in the tile and grout joints. The matting has a grid structure of square cavities which are each cut back in a dovetail configuration. These cavities are filled with thin set mortar that produces a mechanical bond between the mortar and the tile.
