ARDEX WPM 750 - Heat-Welded, Undertile Waterproofing Membrane

Product Description

ARDEX WPM 750 is a weldable sheet membrane system that is used for waterproofing tiled areas such as bathrooms, kitchens, laundries, and wet areas.

Compared to liquid waterproofing membranes, ARDEX WPM 750 Undertile Sheet Membrane gives a thin and consistent waterproofing gauge. This system can fast track installation as there is no need to wait for liquids to dry – simply apply the solvent free adhesive and then the membrane (like wallpaper).

This product has a fleece on both sides of the fabric that help with tile application, while still excelling in durability and waterproofing capabilities.

The laps of the membrane can be heat-welded using a Leister Hot Air Gun ensuring a standard thickness and that all the laps are securely joined, creating a fail-safe waterproofed area.
