LAVA 20 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). LAVA 20 CATALYST is added to LAVA 20 (3 % weight) during application of thick layers as an accelerator for faster curing.

LAVA 20 TOP COAT is a mono component liquid applied roof waterproofing based on an aliphatic polyurethane, that is applied on LAVA 20 (once it is dry, following the manufacturer instructions).
