DAP FireBreak fire‑resistant foam sealant — Orange 12 oz, Class 1 self‑extinguishing & paintable

DAP FireBreak is a bright-orange, flame‑resistant spray foam sealant engineered to fill and seal service penetrations, joints, and gaps while slowing fire spread.

Designed for both commercial and residential use, this Class 1, self‑extinguishing foam blocks air movement through HVAC, plumbing, and electrical openings where flames can travel quickly. FireBreak has been tested to industry standards (including UL‑94 V‑0 and UL‑175) and is formulated to provide a durable, identifiable seal that cures quickly and can be trimmed, sanded, and painted after full cure.

How does FireBreak help stop fire from spreading through wall and ceiling penetrations?

FireBreak fills gaps around pipes, cables, ducts, and other penetrations to limit the airflow that fuels flame movement. Its self‑extinguishing chemistry reduces oxygen at the penetration site so fire spread is slowed through those critical openings.

• Class 1 flame‑retardant rating for high‑risk applications
• Self‑extinguishing formulation reduces oxygen flow at penetrations
• Effective in joints, stud walls, stair stringers, soffits, and drop ceilings

What is the application and cure process for this 12 oz can?

Apply FireBreak between 60°F and 100°F for best expansion and adhesion. The foam becomes tack‑free in about 10 minutes and reaches a full cure in approximately one hour; once cured it can be trimmed, sanded, and painted when needed.

• Tack‑free in ~10 minutes; fully cured in ~1 hour
• Comes with a stop‑and‑restart adapter and an extra straw for multiple uses
• Paintable and sandable after full cure—paint outdoors to avoid discoloration

Where is FireBreak best used—interior, exterior, or both?

FireBreak is formulated for both interior and exterior applications, making it suitable for sealing around HVAC runs, plumbing stacks, and electrical conduit inside walls as well as in protected exterior assemblies. For exposed outdoor installations, paint over the cured foam to prevent UV‑related discoloration.

• Interior and exterior use when protected from direct, prolonged UV exposure
• Ideal for HVAC, plumbing, and electrical service penetrations
• High‑visibility orange color simplifies post‑installation inspection

How does this product perform against industry flammability tests?

FireBreak meets or exceeds several standard evaluations for fire performance, including UL‑94 V‑0 and UL‑175, and performs well in modified ASTM E‑814 testing. These ratings indicate the foam’s suitability for fire‑safety applications where limiting flame propagation through openings is important.

• UL‑94 V‑0 rated for flammability resistance
• Proven performance in UL‑175 and modified ASTM E‑814 evaluations
• Bright orange color for verification during inspections

Who this is for: DAP FireBreak is aimed at contractors, maintenance professionals, and homeowners who need a reliable, detectable fire‑retardant seal for service penetrations and wall or ceiling joints. Choose this 12 oz can when you want a compact, reusable applicator for spot repairs, compliance work in commercial buildings, or fire‑safety upgrades in residential properties.
