3M™ Fire Barrier Sealant, FD 150+, limestone, 20 fl. oz.

An acrylic latex caulk typically used to firestop metal pipes and cables through concrete or gypsum and for use in dynamic head-of-wall systems.

The 3M Fire Barrier Sealant offers a economical alternative to firestopping applications. This 3M fire barrier sealant is a single-part, sag-resistant, water-based acrylic latex sealant and has excellent adhesion characteristics to most common construction materials. In addition, since it dries to the touch within one hour, it can be painted for a more professional-looking job.
