Kraken Bond Extreme Orange Fire Block Foam, 24 oz Straw Polyurethane Sealant, 1 Pack

Kraken Bond Extreme Orange Fire Block Foam is a 24 oz straw polyurethane spray sealant made for larger filling, sealing, and insulating jobs where higher output is useful. It is ideal for gaps, cracks, joints, wall cavities, door and window frames, pipe penetrations, electrical service openings, and other construction areas that require an orange fire-blocking foam. The self-extinguishing formula helps limit flame spread when applied according to instructions, while the cured foam provides a strong, durable, water-resistant, mold-resistant, and paintable seal. Its high-expansion performance helps cover bigger voids efficiently, making it practical for contractors, maintenance teams, and larger DIY projects. The straw adapter allows direct application without a separate foam gun. Clean surfaces before use, condition the can near 68°F, shake well, apply with the can inverted, and leave room for expansion.
