3M™ FireDam Spray 200 is a sprayable water-based material, that dries to form a tough, elastomeric coating. This material when used as part of an assembly will firestop building joints, perimeter joints (curtain wall), and through penetration seals.
Up to 4-hour fire protection in construction joints and up to 2-hour fire protection for through penetration systems
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
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
Easy water clean up
Ideal for firestopping construction joints, perimeter joints, and through penetrations.
