3M™ FireDam™ Spray 200

A sprayable water-based material that dries to a tough elastomeric coating. Designed for use with Thermafiber®* Firespan®* mineral wool and safing insulation and firestops building joints, perimeter joints (curtain wall) and penetration seals. When installed properly, it controls the transmission of fire, heat and smoke.

With up to 50% movement capability, reformulated 3M™ FireDam™ Spray 200 forms a flexible seal that expands/contracts with natural building joint movement to help control the transmission of fire, heat, smoke, noxious gas and water before and during exposure to fire.
