SPRAYMAN Fire Block Foam Sealant offers excellent sealing and insulation for extensive 'gap filler' and 'fireproof insulation' needs. Available in both 20 oz with a gun applicator for larger applications and 12 oz with a straw applicator for precision control. Ideally suited for sealing around electrical outlets and water pipes, this polyurethane expanding foam features 'fire foam' and 'fire block spray foam' properties that are self-extinguishing, making it perfect for filling wide gaps. Environmentally friendly and free from harmful propellants, this foam sealant also serves as a waterproof expandable foam sealant, mold-proof and over-paintable. Meeting stringent safety standards, it is compliant with ASTM E84201 and UL Classified (ICC-ESL-1058).
Key Features:
- Versatile Use: Ideal for door and window insulation, this fire resistant insulation foam not only seals large gaps but also effectively insulates electrical outlets, water pipes, and walls, providing robust adhesion as both door frame foam and window foam to enhance safety and energy efficiency with its airtight sealing capabilities.
- Enhanced Adhesion: Strong adhesion capabilities make this foam an effective foam filler for gaps, particularly useful as a window and door sealer foam and firestop foam, excluding problematic surfaces such as polyethylene and silicone.
- Superior Efficiency: Functions as a fire retardant foam, offering exceptional thermal and acoustical insulation values, ideal for boosting safety and efficiency in both residential and commercial settings.
- Fireproof and Mold Resistant: This fireproof expanding foam is not only mold-proof and waterproof but also fire-resistant, offering comprehensive protection. It can also be painted over to seamlessly integrate with any decor, enhancing both the appearance and functionality of your installations.
- Eco-Friendly: Free from ozone-depleting substances, supporting a healthier environment.
Application Guidelines:
- Safety Precautions: Contains Diphenylmethane-4,4'-Diisocyanate, posing potential health hazards if inhaled or upon contact with the skin. Always wear protective clothing and gloves during application.
- Surface Preparation: Surfaces must be clean, dry, and free of dust, grease, or rust to ensure optimal adhesion. Lightly moisten surface to improve foam expansion and adhesion.
- Optimal Conditions: Best applied at temperatures from +41°F to +86°F. Can should be at room temperature (+68°F) for optimal performance.
- Installation: Shake the can vigorously before use. For gun applicator, attach to the gun, keep the can upside-down, and dispense slowly. For straw applicator, attach the straw, keep the can upside-down, and apply the foam slowly. Start from the bottom of the gap and work upwards to avoid overfilling as the foam will expand.
- Curing and Finishing: Foam is tack-free within approximately 3-6 minutes and cures fully in 24 hours. Once cured, it can be trimmed, shaped, and sanded for precise adjustments. Requires immediate painting or covering to prevent UV damage.
