DeWALT PowerFoam Expanding Polyurethane Foam Spray from DeWALT ANCHORS & FASTENERS is a single-component, moisture-curing polyurethane foam designed for sealing, insulating, and filling gaps throughout residential and commercial construction. Whether you are air-sealing around window frames, filling voids in concrete forms, or insulating pipe penetrations, this expanding spray foam bonds to a wide variety of building substrates - including concrete, brick, wood, metal, aluminum, and steel - delivering a durable, water-resistant seal that holds up over time without rotting or deteriorating with age.

Key Features

• Single-component, moisture-curing polyurethane formula - no mixing required, cures automatically on contact with ambient moisture for fast, reliable results on the job site
• 2-3 times expansion after dispensing - fills irregular gaps and voids thoroughly with minimal product, reducing material waste
• Surface dries in 1-5 hours, fully cured in 12-15 hours - allows for trimming and finishing the same day on most projects
• R-5 equivalent insulation value - delivers thermal and acoustic performance comparable to traditional insulation methods when used to seal gaps and penetrations
• Excellent insulation against heat and noise - hardened foam structure reduces energy transfer and sound transmission through building assemblies
• Class B2 flame retardant - meets fire-resistance classification requirements for use in common construction applications
• CFC-free propellant - environmentally responsible formulation that avoids ozone-depleting chemicals
• Contains no urea formaldehyde or PCBs, and is physiologically harmless when fully cured - safe for use in occupied buildings once the cure cycle is complete
• Water resistant - maintains adhesion and structural integrity in moist or damp conditions after curing
• Does not rot or deteriorate with age - provides a long-lasting seal that retains performance over the life of the building assembly
• Adheres to concrete, brick, wood, metal, aluminum, and steel - versatile compatibility across the widest range of building materials eliminates the need for multiple adhesive products
• Dispensed through a straw-like plastic tube - precise application in tight or hard-to-reach areas reduces overspray and cleanup time
• Works best at room temperature - straightforward storage and use conditions with no special temperature management required on most job sites

Why This Product

• Tackles both insulating and filling applications in a single product - from sealing around window and door frames to filling pipe penetrations and voids in concrete forms, eliminating the need to stock multiple specialty products
• The R-5 equivalent thermal value combined with noise-dampening properties means one application addresses both energy efficiency and acoustic comfort - a practical advantage for residential remodeling and new construction alike
• A safety-conscious formula - free of urea formaldehyde, PCBs, and CFC propellants, and physiologically harmless when fully cured - makes it a responsible choice for contractors working in occupied or sensitive environments
• Broad substrate compatibility across concrete, brick, wood, metal, aluminum, and steel means this foam can be used throughout a project without needing to verify material compatibility at each application point

Frequently Asked Questions

What surfaces can DeWALT PowerFoam bond to?

PowerFoam is formulated to adhere to a wide range of common building substrates including concrete, brick, wood, metal, aluminum, and steel. This broad compatibility makes it suitable for use across many different construction and remodeling applications without needing a separate adhesive for each material type.

How long does it take for DeWALT PowerFoam to cure?

The surface of the foam initially dries within 1-5 hours after application. Full cure is reached in 12-15 hours. The foam works best when applied at room temperature, which supports a consistent and predictable cure cycle.

How much does PowerFoam expand after being dispensed?

After leaving the plastic straw-like dispensing tube, the foam expands approximately 2-3 times its initial volume. This expansion should be factored in during installation to avoid overfilling gaps or voids, and to ensure the foam fills the target area completely without excessive buildup.

Is DeWALT PowerFoam safe to use in buildings once it has cured?

Yes. The product is physiologically harmless when fully cured and contains no urea formaldehyde or PCBs. It also uses a CFC-free propellant. Once the 12-15 hour full cure cycle is complete, the hardened foam is considered safe for contact with common building assemblies in occupied structures.
