StenSeal® PU 300 is a single-component, cold-applied, chemically curing, polyurethane-based, non-sag elastomeric joint sealant and waterproofing material. It has high movement capability and is resistant to dynamic movement. It is resistant to short-term contact with organic and inorganic acids and alkalis, oils, fuels, and many chemicals, and is completely resistant to UV radiation. It offers high bearing strength, and its non-sag structure allows smooth application even in vertical joints.
Areas of Use
StenSeal® PU 300 can be used for all interior and exterior joints. Thanks to its high elasticity, it is especially recommended where connection and joint movements are high, and for joints constructed narrower than required. It is used on floors subject to pedestrian and light vehicle traffic where both high elasticity and bearing strength are required. It can also be used to seal joints in floor coverings between marble, tiles and ceramics, joints between walls and joinery, and pipe passages.
