Vexcolt VX Liquid Master

VX Liquid Master is a caulk-applied, one-component, hydro-swelling mastic designed for sealing smooth and rough construction joints and pipe penetrations in wet or underwater applications. It is a grey, polyurethane-based, elastic, hydro-swelling mastic supplied in cartridges and aluminium sausages, suitable for sealing expansion joints and areas around pipe penetrations.

VX Liquid Master cures and swells in the presence of moisture. Curing time depends on temperature and humidity, with higher temperature and relative humidity accelerating the process. The product will typically become firm within 24–36 hours, and its long-term performance is not affected by the curing time.
