The StoGuard Gold Coat TA is the newest addition to Sto Corp.’s StoGuard air and moisture barrier product suite. The fluid-applied vapor-permeable membrane integrates with continuous insulation systems and can be troweled directly onto vertical, above-grade wall sheathing and concrete masonry. The company says the treatment minimizes the risk of water damage and condensation, eliminates the problem of air leakage between an air barrier and sheathing, and remains stable under air pressure or wind loads. StoGuard Gold Coat TA is low-VOC and safe for both interior and exterior use. Pricing varies.
