AQUABLOK WPU is formulated on water based polyurethane polymer technology. The cured membrane is a class 3 with high flexibility. WPU is a premixed, single component, elastomeric waterproofing membrane for use in internal and external applications and under tiled finishes including shower recesses, bathrooms, laundries, decks, balconies, podiums and rooftops. WPU is water based with low VOCs and forms a flexible, seamless waterproofing membrane. It bonds to a wide variety of substrates and is UV stable and may be left exposed. WPU may be recoated in 4 hours, tiled over after 48 hours and can be flood tested 72 hours after the final application. WPU contains micro fibre reinforcement which provides excellent tensile strength and elongation.
