Rapid Bathroom Waterproofing with ARDEX WPM 750

*To be installed by a certified installer*

ARDEX WPM 750 Undertile Butynol is a premium Weldtec sheet membrane specifically designed for waterproofing tiled areas like showers and bathrooms. This high-performance system ensures a consistent waterproofing gauge, eliminating the risks associated with uneven liquid membrane application.

Efficiency and Speed

Streamline your workflow with the ARDEX Weldtec system. As a sheet-applied membrane, it requires no curing time for the membrane itself. Applied like wallpaper using a solvent-free adhesive, tiling can begin in as little as 60 minutes. The dual-fleece design provides the legendary durability of Butynol while ensuring high-strength lap joins for a permanent waterproof seal.
