Isomat VARNISH-PU 2K-W impregnating varnish is a two-component, water-based polyurethane coating. It protects and waterproofs trowel-finished cement screed, concrete, natural stone, and wood, forming a transparent satin-matt film that does not yellow when exposed to ultraviolet radiation. It is resistant to weather, cleaning agents, oils, seawater, and alkalis. The coated surface can withstand pedestrian traffic and light vehicle traffic.
Apply with a roller, brush, or spray in 2 to 4 coats. The substrate must be dry and clean, with a moisture content below 4%, and relative humidity must be below 65%. Mix components A and B at a ratio of 100:25 by weight. The mixture can be diluted with up to 10% water. Clean tools with water while the product is still wet.
