Waterstop-GunGrade is a single component hydrophilic waterstop, designed for sealing smooth to very irregular construction joints and pipe penetrations. It cures and swells in the presence of moisture or water. Curing time depends on temperature and humidity, for example cure time decreases when temperature and RH are higher. Waterstop-GunGrade cures 24-36 hours. Waterstop-GunGrade is available in cartridges and sausages.
