Impey WaterGuard Waterproof Membrane Kit

This kit provides a complete, high-performance leak-proof sealing solution designed for both wetroom floors and walls.

Featuring a 1mm thick, highly flexible, self-adhesive butyl rubber backed membrane with a polypropylene fleece facing, it acts as an impenetrable barrier against water ingress.

Engineered for rapid, clean application with zero curing time required, WaterGuard enables installers to tile immediately after laying.

It features highly elastic de-coupling properties to protect tiled surfaces from structural movement and is fully tested to support vertical wall loads of up to 30kg/m2 across various substrates including plasterboard, cementboard, and plyboard.

Fully compatible with Impey wetroom systems and Aqua-Mat underfloor heating systems, WaterGuard offers ultimate peace of mind backed by Impey's Lifetime Watertight Guarantee.
