Moistop Sealant makes it easy to get extraordinary results from an ordinary caulking gun. A continuous bead on the window nail flange gives long lasting protection against moisture infiltration. Even though Moistop Sealant is tough enough to repair torn weather-resistive barriers, it is smooth enough to take paint in visible application areas.
Effective on wood, vinyl and aluminum flanges, Jumbo Tex® building paper, WeatherSmart®, PlyDry®, and all Fortifiber flashings
Exceedes ASTM C-920 and AAMA 808.3-92 (Exterior Perimeter Sealing Compounds) standards
