High-Performance Expanding Foam for Filling, Sealing and Insulating
The Soudal Soudafoam Gap Filler Hand Held 750ml delivers a fast, reliable solution for filling gaps, sealing cavities and improving insulation across a wide range of construction and home improvement projects. This one-component polyurethane expanding foam expands into voids and hard-to-reach spaces, creating an effective seal against air movement, moisture and noise.
Whether you need to install window and door frames, seal pipe penetrations or fill irregular gaps within roofing and construction applications, this expanding foam provides excellent adhesion to most common building materials. Furthermore, the hand-held application allows quick and convenient use without the need for a foam gun.
As the foam cures, it delivers outstanding thermal and acoustic insulation. Consequently, it helps reduce heat loss, minimise draughts and improve energy efficiency throughout the building.
Why Choose Soudal Soudafoam Gap Filler?
Builders, roofers and tradespeople rely on expanding foam to fill voids quickly and effectively. Therefore, Soudal developed Soudafoam Gap Filler to combine high expansion performance with excellent ease of use.

Installation Advice
Firstly, shake the can thoroughly before use and ensure all surfaces remain clean, dry and free from dust, grease or loose debris. Next, apply the foam into the gap, filling approximately one-third of the cavity to allow sufficient room for expansion during curing. Additionally, lightly moistening porous surfaces can help accelerate the curing process and improve overall foam performance.
Once the foam has fully cured, carefully trim away any excess material to achieve a neat finish. Thereafter, you can sand, plaster or paint the cured foam to match the surrounding surface. As a result, you can create a professional-looking finish while maintaining excellent sealing and insulation properties.
