Tile Uncoupling Membrane

Use unmodified thin set to adhere the tiles to the membrane.

Tile uncoupling membrane.

Modified thin set mortars need air to cure properly and. They are only 1 8 inch thick and raise the height of the finished floor by a negligible amount. Another solution is installing uncoupling membranes or mats to provide this function in a less intrusive manner. Completely fill the square cavities of the uncoupling membrane with thin set.

They are flexible non rigid and provide no support for the tiles. Uncoupling membranes designed for ceramic and stone tile installations provide waterproofing and help prevent cracking. Uncoupling membranes differ from cementboard in three other important ways. The tiles are bonded to the top surface of the mat while the loosely bonded bottom fleece is bonded to the concrete subfloor.

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. This creates the strong bond necessary. Uncoupling membranes in the tile assembly are fast becoming an essential and affordable part of the tile installation process. They require no fasteners just adhesive to hold them to.

Uncoupling is a method that can be used with all of the most common joist spans used in residential construction. The powers that be in the tile industry want uncoupling membranes to be their own classification separate from the cis membranes. Uncoupling ditra tile has been successfully installed for thousands of years by incorporating an uncoupling layer or forgiving shear interface within the tile assembly.
