WEBERDRY PUR SEAL is a mono component liquid applied roof waterproofing based on polyurethane consisting of a polyurethane elastomeric membrane without or with internal mesh; which once polymerized conforms an elastic lining, in form of a layer completely bonded to the support (steel, concrete, mortar, ceramic, PU, PU) and other waterproofing membranes like PVC, EPDM and bituminous (for each kind of substrate application with suitable primer, following the indications of the manufacturer). WEBERAD CATALISER is added to WEBERDRY PUR SEAL (3 % weight) during application of thick layers as an accelerator for faster curing.
WEBERDRY PUR COAT is a mono component liquid applied roof waterproofing based on an aliphatic polyurethane, that is applied on WEBERDRY PUR SEAL (once it is dry, following the manufacturer instructions).
The minimum layer thickness of the assembled system has to be 1.0 mm without internal mesh and 1.2 mm with internal mesh.
