The 3M 7100009734 is a gun-grade, latex-based elastomeric firestop sealant designed for use in passive fire protection systems. It cures upon exposure to the atmosphere to form a monolithic, flexible seal. When installed in tested and listed systems, it provides up to 4-hour fire resistance. The sealant also functions as a smoke and noxious gas barrier and delivers an STC rating of 56 when tested in a qualifying wall assembly. It ships ready to use in a 20 fl oz sausage package in limestone color, with no mixing required. Licensed HVAC, fire protection, and general construction contractors typically install this product per listed system drawings.
This sealant is applied to construction joints and through-penetrations in fire-rated wall and floor assemblies. It is suited for both residential and commercial construction wherever firestop continuity is required at penetrations for pipe, conduit, cable, or ductwork. The limestone colorway integrates with concrete and masonry substrates. It meets International Building Code requirements and the intent of LEED VOC environmental regulations, making it appropriate for green-building and code-compliance projects.
Designed for use in tested and listed firestop systems at construction joints and through-penetrations in fire-rated floor and wall assemblies. Exhibits adhesion to a full range of construction substrates including concrete, masonry, gypsum board, and metal.
Installation must follow the specific tested and listed system details applicable to the penetration type and fire-rating required — do not deviate from the listed system drawing. This product is typically installed by licensed fire protection contractors, journeyman electricians, plumbers, or HVAC technicians as part of a complete firestop system. Ensure substrate surfaces are clean, dry, and free of dust or loose material before applying sealant. Consult applicable building codes including IBC and local authority having jurisdiction requirements before beginning work.
