PU850 Liquid Waterproofing Membrane
RLA PU850 is a one-component, moisture curing
polyurethane waterproofing membrane that cures to form
a tough elastic film with strong adhesion over most
common building surfaces.
PU850 maintains exceptional flexibility and elastomeric
properties, providing a durable waterproofing solution for
under screed, external and underground applications.
