CEM 805 Active is a one-component, polyurethane-based, solvent-free, hydroswelling sealing agent for sealing construction joints and around pipe penetration. It cures and swells in the presence of moisture.
CEM 805 Active will typically become firm in 24 to 36 hours. Curing time is dependent on temperature and humidity conditions. For example, curing time will reduce if the relative humidity and temperature are higher.
