Grey Acoustic Sealant 825ml

The Black Jack Acoustic Sealant is a high-performance acoustic sealant made from a blend of synthetic rubber polymers specifically formulated to provide exceptional adhesion when installing a polyethylene vapor barrier. It adheres effectively to most common building materials, ensuring a durable and reliable installation. Thanks to its flexible, non-film-forming formula, it remains supple, does not dry out, and maintains its adhesive strength over time, even under demanding conditions. Versatile, it can also be used as a filler compound around vibrating elements, electrical boxes, or any component recessed into or passing through walls, ensuring optimal sealing. Designed for use on unexposed surfaces, it offers water resistance and consistent performance in both residential and commercial applications. Its gray color allows for discreet integration within assemblies.
