3M LM 120 FIRE STOP 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.
Features :
- Re-enterable/repairable with common hole saw
- Paintable with primer
- Halogen-free formula
- Water clean up (prior to cure)
Applications :
3M Fire Barrier Mortar is a cost-effective firestop typically used to seal mechanical and electrical service penetrations, blank openings and other large annular spaces in fire-resistance rated wall and floor assemblies with ratings up to 3 hours.
The firestop material can be mixed to a self-leveling consistency (2 parts mortar mix: 1 part water) for floor applications or it can be mixed to a trowelable consistency (3 parts mortar mix: 1 part water) for application to vertical and horizontal substrates.
