Up to four hours of fire protection in construction joints and up to two hours of fire protection for through penetration systems
Easy water clean up
Highly elastic material maintains performance with up to ± 50% movement capabilities
Superior adhesion to most construction materials
Broad range of applications (extensive portfolio of tested and listed construction and perimeter joint systems)
Improved spraying pattern — applied with conventional airless spray equipment
Paintable
Robust jobsite formula (freeze/thaw resistant and uniform seal formation in hot or cold drying conditions)
Improved spraying for lower sag, uniform coating build properties (stays where it’s sprayed)
Improved hiding power to maintain proper coating thickness
3M™ FireDam™ Spray is a water-based material that dries to form a durable, elastomeric firestop coating. This material, when used as part of an assembly, will firestop building joints, perimeter joints (curtain wall), and through penetration seals.
Suggested applications
Ideal for fire stopping construction joints, perimeter joints, and through penetrations
