This kit can be used for different working life depending mainly of this thickness:
IMPERTHANE MEMBRANA PU is a liquid applied roof waterproofing kits based on pure polyurethane. It consists of a polyurethane resin, liquid-applied, mono-component, elastomeric with or without internal protection layer. IMPERTHANE MEMBRANA PU / IMPERTHANE MEMBRANA PU TIXOTRÓPICO reacts with the environmental humidity (direct reaction). WOLLTHANE AC 1C FLEX is moisture triggered cured (indirect reaction).
Once polymerised they conform an elastic lining, in form of a layer completely bonded to different supports (steel and other types of metals, concrete, mortar, ceramic, timber, polyurethane foam and other waterproofing membranes like PVC, EPDM and bituminous). Depending on support condition, other type of primer may be advisable.
