Blockade 18858 Fire Blockade Acrylic Sealant, Red, 10.1-oz.

Dap Blockade is a single-component, water-based intumescent acrylic firestop sealant designed to seal penetrations and gaps where fire protection is critical. When exposed to heat during a fire, the sealant expands to fill voids created by burning combustible materials, maintaining the integrity of fire-rated assemblies. This product treats general firestopping applications for combustible and noncombustible penetrations, including cables, pipes, ducts and other building elements.

Dap Blockade meets ASTM E 814 and UL 1479 specifications for fire tests of penetration firestops, giving builders and contractors confidence that their firestopping systems will perform when needed most. The red color makes completed applications easy to inspect and verify coverage, ensuring thorough protection throughout the structure.
