High-performance PU sealant: Single-component, dimensionally stable with low-tension - ideal for precise sealing with high strength in a wide range of applications.
fischer Construction PU is a one-component polyurethane sealant that reacts with atmospheric moisture and cures evenly and pore-free with virtually no shrinkage. It has high strength and is specially designed for dimensionally stable joints with little movement. The sealant is very easy to apply and adheres reliably to many different substrates. Construction PU can be painted over with water-based paints and offers good resistance to weathering, ageing and UV exposure.
