About this item

SpecSeal® Smoke 'N' Sound Sealant is a high‑quality acrylic latex sealant engineered for sealing through‑penetrations—including pipes, conduits, cabling, busways, and various mechanical openings—as well as membrane penetrations such as P‑traps and electrical outlet boxes in smoke‑rated wall assemblies. This versatile sealant also performs exceptionally well in linear joint applications, including wall‑to‑wall and head‑of‑wall joints designed to be static or minimally dynamic. Manufactured as a single, multipurpose grade, SpecSeal Smoke 'N' Sound Sealant offers excellent caulking, high‑build, and adhesion properties, making it ideal for vertical and overhead applications. It can be applied using standard cartridges, bulk loading, knifing, or troweling techniques, providing installers with maximum flexibility on the jobsite. Free of PCBs and asbestos, this sealant delivers a safe, and durable solution for controlling smoke migration, restore acoustic performance, and supporting long‑term assembly integrity in commercial, industrial, and multifamily construction.
