Our 3M™ FireDam™ Spray 200 is a sprayable material that dries to form a tough, elastomeric coating. It will firestop building joints, curtain wall perimeter joints and through penetration seals to control the transmission of fire, heat, smoke and noxious gas. This water-based firestop sealer is applied with conventional airless sprayers, dries quickly and cleans up easily.

Effective Fire Protection in a Flexible, Durable Coating
Formulated for flexibility that stays where it’s sprayed, our 3M™ FireDam™ Spray 200 controls the transmission of fire, heat, smoke and noxious gasses before, during and after exposure to fire. It provides up to 4-hour fire protection in construction joints per ASTM E 1966 (UL 2079) and up to 2-hour protection for through penetration systems per ASTM E 814 (UL 1479) & CAN/ULC-S115. It also provides up to 3-hour fire protection in perimeter fire barrier systems (curtain walls) in accordance with ASTM E 2307. This firestop coating is Ideal for sealing building joints, penetration seals and perimeter joints between fire-rated floors and fire-rated walls. It also minimizes noise transfer (STC Rating of 56 when tested in a STC 56-rated wall assembly).

This elastomeric coating forms a durable, flexible seal with up to +/- 50% compression/extension of nominal joint width without cracking. It resists sag for vertical applications, and displays excellent hiding power which makes it easier for technicians to maintain the proper coating thickness.
