Transparent, brushable, durable, semi-rigid / elastic aliphatic, single-component polyurethane-based membrane, used for long-term waterproofing over paving. It is not affected by ultraviolet radiation (UV), does not yellow, is not attacked by the alkalis of the substrate, and even after aging remains transparent and elastic. It waterproofs ceramic, stone, and glass surfaces and protects them from moisture, acid rain, smog, and ice. Oxidized, transparent, polycarbonate surfaces appear more transparent after being coated with MARIΤRANS®.
