UniverSeal US-100 liquid tape is a polyether based, moisture curing, elastomeric sealant. It forms a seamless, monolithic exterior working surface that will keep the structure watertight. Its distinctive blue color allows for quick & easy visual verification that all seams and gaps have been effectively sealed from wind and rain.

Universeal US-100 liquid tape is a non-shrinking, 100% solids, moisture-cure polymer and contains no solvents and trace amounts of VOC’s.  It skins in one hour, cures completely in three to seven days (cure rate varies with temperature and relative humidity) and is paintable within 24 hours.
