Xtreme Pro Fire Block Spray Foam 24 oz, Gun Use

Xtreme Pro Fire Block Spray Foam is a professional-grade, one-component polyurethane insulating foam sealant designed for fire blocking, air sealing, and gap filling in residential, commercial, and industrial construction applications.

Developed specifically for foam gun application, this high-performance formula delivers superior control, higher yield, and cleaner results compared to straw-applied foams. Once cured, it forms a durable, airtight, and moisture-resistant seal that helps improve fire safety, energy efficiency, and long-term structural integrity.

Features & Benefits

• Mold-Proof & Waterproof : Creates a moisture-resistant seal that helps prevent mold growth and water penetration once cured.
• Heat Resistant Performance : Remains stable in extreme temperatures ranging from -40°F to 194°F.
• Reusable with Applicator Gun : Designed for professional gun use, allowing precise control, reduced waste, and repeated applications.
• Over-Paintable : Can be painted over after curing for a clean, finished appearance.
• Eco-Friendly Formula : Engineered to meet modern environmental standards while delivering professional-grade performance.
• Blocks Air Leaks : Seals gaps and penetrations to reduce air infiltration and improve energy efficiency.
• Excellent in Dry & Humid Climates : Performs reliably in both dry and high-humidity environments.
• No Shrinking or Melting : Maintains dimensional stability over time without shrinking or melting.
• Class A Fire Rating (ASTM E84) : Meets Class A fire performance requirements under ASTM E84 testing.
• Fills Gaps from 1/4" to 3" : Effectively fills and seals gaps ranging from ¼ inch to 3 inches.

Application Areas

• Fire blocking around pipe, conduit, and cable penetrations
• Sealing electrical boxes, junction boxes, and service openings
• Air sealing in basements, crawl spaces, attics, and garages
• Filling gaps around window and door frames
• Sealing construction joints, framing gaps, and wall-to-floor connections
• Professional insulation and fire-stop preparation work

How to Use

• Shake the Can & Attach to Gun : Shake the can thoroughly before use, then securely attach it to a compatible professional foam applicator gun.
• Apply at Proper Temperature : Apply the foam when ambient temperature is between +32°F and +112°F to ensure optimal expansion, adhesion, and curing performance.
• Hold the Can Upside Down : Always hold the can upside down during application to maintain proper foam flow and consistency.
• Allow Full Cure : The foam becomes fully cured in 24 hours, depending on temperature and humidity conditions.
