Waterproofing Membrane Application (Schluter-KERDI)

What happens here

The Schluter-KERDI waterproofing membrane, a sheet-applied system, is installed over the moisture-resistant drywall. Thin-set mortar is applied to the wall surface with a flat trowel and then combed with a notched trowel to create an even bed. The KERDI membrane is then pressed firmly into the fresh thin-set, ensuring full contact and no air pockets. A flat trowel or screed is used to embed the membrane and remove excess thin-set. Joints and corners are overlapped by at least 2 inches, and KERDI-BAND is used for all seams, ensuring a continuous waterproof layer. The membrane is also applied to the ceiling of the shower.

Goal: The Schluter-KERDI waterproofing membrane is applied to the shower walls and ceiling using thin-set mortar, ensuring a continuous and watertight barrier.
