With heat-welded laps, ARDEX WPM 750 is a premium solution for undertile waterproofing.
A watertight solution for wet area projects such as bathrooms, kitchens and laundries, ARDEX WPM 750 is a heat-welded rubber sheet waterproofing system that is not only safe and secure with a 15-year material guarantee, but can also fast track project completion time.
Unlike liquid waterproofing membranes, ARDEX WPM 750 Undertile Sheet Membrane gives a thin and consistent 0.5mm waterproofing gauge with no need to wait for liquids to dry. Solvent-free adhesive is first applied, followed by the membrane — rather like hanging wallpaper — and tiling can commence just one hour after the membrane is installed.
A fleece on both sides of the fabric helps 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 to ensure a standard thickness, limited application error and that all laps are securely joined, creating a fail-safe waterproofed area.
ARDEX WPM 750 meets durability standard NZBC B2.3.1 (b) 15 years and has BRANZ Appraisal (No 727). The product is also part of the Warmup Wetroom BRANZ Appraisal for use with undertile heating systems.
New Zealand's most secure undertile waterproofing system, ARDEX WPM 750 is suitable for use on a variety of substrates, including plywood and timber, concrete, fibre-cement sheeting, and wet wall linings such as Gib Aqualine and Villaboard. The product can be used internally on both walls and floors and should be installed by an ARDEX Approved Applicator.
For fail-safe waterproofing and fast-tracked project timing, ARDEX WPM 750 offers superior benefits for all wet area projects.
