3M Fire Barrier Mortar

GIC 3M Fire Barrier Mortar firestop

3M Fire Barrier Mortar

3M™ Fire Barrier Mortar is a lightweight gypsum-based and endothermic firestop that is ready for mixing with potable water. 3M™ Fire Barrier Mortar will firestop penetrations passing through fire-rated floor or wall assemblies and other fire-rated interior building construction. 3M™ Fire Barrier Mortar exhibits excellent adhesion to a full range of construction substrates and penetrants. In addition, it will act as a heat sink, absorbing heat from penetrants and reducing the likelihood of combustible matter igniting on the unexposed side of the assembly.

Variable Mix Ratio: permits self-leveling as well as trowelable application consistencies, resulting in labor
savings.
