StenCoat® PUM 301 is a single-component, polyurethane-based, highly elastic, thixotropic and easy-to-apply decorative waterproofing and protective coating. Applied as a liquid, it forms an elastic, breathable and waterproof coating. Thanks to its thixotropic structure, it can be applied to sloped and vertical surfaces as well as horizontal ones. Its high elasticity and crack-bridging ability make it resistant to substrate movements, and it keeps its mechanical properties under outdoor conditions. StenCoat® PUM 301 complies with the ASTM C 836 waterproofing membrane standard and is classified as type PI-C according to EN 1504-2.
Areas of Use
