Flame Stopper 5000 Sealant is a flexible intumescent acrylic latex firestop sealant designed to prevent the spread of fire, smoke, and toxic fumes through wall and floor penetrations. When exposed to extreme heat, the sealant expands (intumesces) to block openings and help maintain the fire rating of construction assemblies.

This professional-grade firestop sealant is commonly used around cables, pipes, ducts, and construction joints in residential, commercial, and industrial buildings.

Key Features

• Intumescent firestop technology – expands when exposed to heat to block fire spread

• Flexible acrylic latex formula that resists cracking and vibration

• Stops smoke, toxic fumes, and fire migration through penetrations

• Interior and exterior applications

• Paintable once cured

• Easy cartridge application using a standard caulking gun
