Tile Uncoupling Membrane

The powers that be in the tile industry want uncoupling membranes to be their own classification separate from the cis membranes.

Tile uncoupling membrane.

Schluter ditra membranes provide uncoupling through free space which allows for in plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile thus eliminating the major cause of cracking and delaminating of the tiled surface. Uncoupling membranes differ from cementboard in three other important ways. They are flexible non rigid and provide no support for the tiles. The tiles are bonded to the top surface of the mat while the loosely bonded bottom fleece is bonded to the concrete subfloor.

Uncoupling membranes seem like they would prevent cracks also. Uncoupling is a method that can be used with all of the most common joist spans used in residential construction. Another solution is installing uncoupling membranes or mats to provide this function in a less intrusive manner. Modified thin set mortars need air to cure properly and.

Completely fill the square cavities of the uncoupling membrane with thin set. Uncoupling membranes designed for ceramic and stone tile installations provide waterproofing and help prevent cracking. Uncoupling ditra tile has been successfully installed for thousands of years by incorporating an uncoupling layer or forgiving shear interface within the tile assembly. They are only 1 8 inch thick and raise the height of the finished floor by a negligible amount.

This creates the strong bond necessary. But the fact is that they haven t been officially tested as crack isolation membranes. Here are a few tips to ensure all goes as planned.
