RPM PU Foam Spray

The foam expands several times its liquid volume (typically 3–5x) after application. It cures under low pressure, allowing easy shaping. You’ll reach a workable firmness after about 2 hours, with full cure typically within 24 hours. It’s designed to reduce bubbles and oozing for cleaner seals.

It bonds well to most common building materials such as wood, metal, glass, brick, and concrete. It is formulated to resist cracking and shrinking over time and to help improve energy efficiency by sealing gaps effectively.

This SKU is the 500 ml can of RPM PU Foam Spray. RPM also offers a larger 750 ml Multi-Purpose PU Foam for bigger jobs, which shares similar expansion and bonding characteristics.

Yes, the foam is described as fire retardant and water-resistant, making it suitable for both insulation and weather-sealing tasks in appropriate applications.

Wear protective gloves and eye protection, ensure adequate ventilation, and avoid skin contact. Keep away from heat, sparks, and open flames. Follow the safety instructions printed on the can label.

Use RPM PU Foam Spray for gaps around windows and doors, sealing pipe penetrations, insulating hard-to-reach spaces, and air-sealing around electrical or mechanical fixtures. It can also be used to dampen noise and improve energy efficiency in buildings.

Store the can upright in a cool, dry place away from heat sources. Keep the container sealed when not in use. Check the expiration date on the can and use the product within the recommended timeframe after purchase.

Return eligibility depends on Fepy’s return policy. If the item is unused and returned within the allowed window, you may be eligible for a return or exchange.

Both products offer similar expansion, bonding to common materials, and curing behavior. The 750 ml option provides a larger volume for bigger jobs, while the 500 ml can is convenient for smaller projects.

Both are PU foams with fire-rated properties, but the 750 ml Fire Rated variant is targeted toward areas where fire safety ratings are required and may have different performance specifications. Compare the two at: https://fepy.com/product/rpm-fire-rated-pu-foam-750ml

If oozing occurs, apply smaller amounts and wipe away excess before it cures. For bubbles, apply in thin layers and allow time for curing between passes. If curing seems uneven, ensure proper ventilation and follow the application steps carefully. For persistent issues, remove cured foam with appropriate tools and reapply.
