Fire Barrier Mortar
3M Fire Barrier Mortar is a lightweight cementitious firestop product. It is available in poly/paper bags and ready for mixing with potable water. 3M Fire
Barrier Mortar does not contain MMMF (man-made-mineral-fibers) or asbestos and does not require fibrous damming materials. 3M Fire Barrier Mortar contains binders free of portland cement and therefore has greater resistance
