3M™ Fire Barrier Sealant FD 150+ Limestone Sealant - 591ml Sausage

Features
This sealant acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 56 when tested in a STC 56-rated wall assembly). 3M designed this fire barrier sealant to be water-based for easy installation, cleanup and disposal. In addition, the high-solids formula produces limited shrinkage. This halogen-free sealant is sag-resistant and has an excellent caulk rate (applied with conventional caulking equipment). It dries to the touch in within 60 minutes and can be painted. This sealant has also been engineered to be re-enterable and repairable.
