Kraft Joint PU 25 polyurethane sealant is a one-component product that transforms from a thixotropic paste into an elastic mass upon contact with atmospheric air. It is used to seal and bond similar and dissimilar materials in buildings, in vertical and horizontal joints.
It adheres to ceramics, cement, glass, wood and galvanized sheet metal, and is suitable for joints subject to high movement. It has a recovery capacity of over 90%, resists UV radiation and moisture, and can be painted with standard paints. The surface must be dry and clean before application. Clean tools immediately with Kraft White Spirit.
