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
When installed properly 3M FireDam Spray 200 will control the transmission of fire, heat and smoke before, during and after exposure to fire. Ideal for sealing building joints, penetration seals and perimeter joints between fire-rated floors (concrete, fire-proofed fluted steel decks) and fire-rated walls (gypsum, concrete). Applied as 1/8 inch (3mm) thick coating with an airless sprayer, this water-based coating dries in ambient conditions to form a flexible seal with compression/extension of up to +/- 50% of nominal joint width.
- Dries quickly to dark gray or red
