Don’t just tape it, Seal it! Hardcast^® Foil-Grip 1402 is a UL classified, pressure-sensitive, 40-year cycle, general-purpose rolled mastic sealant designed to provide an airtight seal on metal or flexible duct work. This Zero-VOC rolled sealant bonds to metal instantly with no mess or cure time—and you can perform pressure tests right away. Available with an unprinted or printed foil facer, this mastic rolled solution is ideal for change-outs and installations. Use alone or pair with Hardcast Liquid Sealants for long-lasting performance. Also available, UL 181B-FX-listed rolled mastic sealants Foil-Grip™ 1403, that offers easy tear, and Foil-Grip™ 1404 that offers colder applications temperatures.

With no VOCs, fast application, and superior flexibility, it’s the smart choice for pros who demand lasting seals. As Jake Greenberg of Delta Mechanical states, “We have had such success with Foil-Grip that we have eliminated liquid sealant on all external connections…Crews can pressure test the same day the sealant is applied, keeping projects on schedule while meeting strict leakage standards.”
