PU-XSEAL ULTRA
High- Performance Water Based Polyurethane Elastomeric Waterproofing Coating
hahne PU-XSEAL ULTRA is a water-based, low-solvent, highperformance elastomeric waterproofing membrane designed to form a seamless, flexible and durable protective layer over suitable building substrates. Its high elasticity and crack-bridging capability enable the membrane to accommodate substrate movement and provide reliable waterproofing performance. The product is suitablefor exposed exterior applications and is designed for applications requiring enhanced flexibility and crack-bridging performance.
