Kraken Bond Extreme Orange Fire Block Foam, 12 oz Straw Polyurethane Sealant, 2 Pack

Kraken Bond Extreme Orange Fire Block Foam is a 12 oz straw-applied polyurethane sealant designed for filling, sealing, and insulating gaps, joints, wall penetrations, window and door frames, and service openings around pipes or wiring. The orange color helps make applied areas easier to identify during fire-blocking work, while the self-extinguishing formula helps reduce flame spread when used as directed. This high-expansion foam adheres to many common building materials and cures into a durable, mold-resistant, water-resistant, and paintable seal. The included straw adapter makes application simple for DIY repairs, maintenance jobs, and professional construction use without a foam gun. For best results, apply to clean surfaces, lightly mist with water when appropriate, use the can near 68°F, and avoid overfilling because the foam expands after application.
