A one component moisture curing, paintable, high modulus polyurethane sealant and adhesive. It has excellent adhesion to most building substrates and is fast curing with permanent and durable elasticity.


For interior and exterior waterproof joints in building and metal constructions. For gluing, sealing, mounting and anchoring in building applications. For use in metal and mechanical construction, ship building and container sealing joints, refrigeration plants, automotive, caravan, mobile home, aircraft and the railway industry.


Surfaces must be sound, clean, dry and free from oil and grease. Any residues must be thoroughly removed prior to application of sealant. Priming is not usually necessary – most substrates only require priming if testing indicates a need. Once fully cured all harmful solvents will have evaporated off and the product will be safe for the introduction of aquatic organisms. Cut the cartridge seal and screw on the nozzle, which should be cut to your required size. Using a skeleton gun, apply the sealant firmly into the gap or joint ensuring a good solid fill, making sure no air is trapped behind. If required place masking tape along edges, removing within 10 minutes of application.
