This uncoupling membrane is a must-have if you're laying tile over concrete, plywood, or other substrates that might move or crack.

It's a 3.3-foot by 33-foot roll, giving you 108 square feet of coverage – enough for a medium bathroom or a decent-sized kitchen.

At 1/8 inch thick, it's lightweight but does serious work: it absorbs substrate movement, prevents cracks from transferring up through your tile, and provides a waterproof barrier that keeps moisture from seeping into the subfloor.

The yellow color is easy to see and work with, and the grid structure with anchor fleece ensures a tight bond with modified thin-set mortar.

Installation is straightforward – just cut it to size with standard tools, lay it over your prepared subfloor, and trowel mortar right over it.

No need to wait for the mortar to harden before you start tiling, so you can keep your project moving.

It's ideal for kitchens, basements, bathrooms, and shower rooms where water and movement are concerns.

Tear-resistant and flexible, this membrane gives you peace of mind that your tile job will last without cracks or tenting.
