Polyurethane sealant is a one-component, moisture-curing, and polyurethane-based sealing material.
It is used for filling the joints between the building elements, laying the roof tiles, assembling PVC window joinery, wooden doors and windows, filling the gaps between the wall and the joinery, joints of the prefabricated building elements and the rainwater collection pipes on the roofs and the rain gutters. It is also intended for filling the working margins left open between the precast concrete blocks.
