Description

Waterproofing Membrane is designed for application to walls and floors beneath a ceramic, porcelain or natural stone tile finish in wet areas and installations where problems with water ingress are possible. The use of Waterproofing Membrane Tape and Matting reinforces the membrane to allow for extra movement in areas such as junctions between walls and floors, internal and external corners, suspended floors, around floor drains and channels and in heavily trafficked areas such as communal showers.

Preparation:

Surfaces to be clean, completely dry, sound and free from contamination and be capable of standing the loading of the tiled finish. The surface must be flat and free from any gaps or cracks.
