RLA PU850 Liquid Waterproofing Membrane

RLA PU 850 is a one component, thixotropic, under screed polyurethane waterproofing membrane where viscosity of the liquid is paramount. In applications such as sloped roofing, flashing details waterproofing. RLA PU 850 cures to form a durable yet elastic membrane with strong adhesion to many types of substrates.PU 850 complies with AS/NZ 4858 for Class 3 membrane. RLA PU 850 is fast curing, and is tack-free in less than two hours, with exceptional elasticity. Due to its thixotropic, hydrophobic and elastomeric nature, RLA PU 850 is the perfect solution to provide excellent waterproofing on vertical and sloped surfaces without running.
