Application and Surface Preparation
For best results, ensure all surfaces are clean, stable and free from dust, grease and loose contaminants. Lightly dampening the substrate before application helps improve curing performance and foam expansion.
Shake the can thoroughly before use and unfold the integrated Genius Gun applicator. Apply the foam carefully into the cavity or joint, filling approximately one-third of the available space to allow for expansion during curing.
For deeper voids, apply in multiple layers and lightly moisten between applications. The Genius Gun system allows precise foam control, helping reduce waste and improve accuracy in difficult areas.
Fresh foam can be removed using a suitable PU foam cleaner. Once cured, excess foam should be trimmed mechanically using a sharp knife or cutting tool.
Where used externally, cured foam should be protected from direct UV exposure by covering, painting or sealing with an appropriate product.
Advantages
- Combines professional foam performance with easy application.
- Provides precise dosing and improved control.
- No need for a separate foam gun.
- Excellent thermal and acoustic insulation properties.
- High filling capacity for larger gaps and cavities.
- Reliable long-term stability after curing.

Frequently Asked Questions
What is Soudal Gap Filling & Expanding Foam Genius used for?
This expanding polyurethane foam is designed for filling, sealing and insulating gaps, cavities and penetrations in construction projects. It is commonly used around pipework, roof openings, structural voids and service installations. The foam expands after application to create an effective seal while improving thermal and acoustic performance.
What is the Genius Gun system?
The Genius Gun is Soudal’s integrated applicator system that provides greater control than standard foam straws. It allows more precise dispensing, reduces product waste and makes application easier in difficult-to-reach areas. The system also enables the can to be stored and reused more conveniently.
Can the foam be used outdoors?
Yes, the foam is suitable for many external sealing and insulation applications. However, cured polyurethane foam is not resistant to prolonged UV exposure. For long-term durability, the foam should be protected with paint, sealant or another suitable covering material.
How much should I fill a gap when applying the foam?
Because the foam expands significantly during curing, cavities should generally be filled to around one-third of their volume. This allows room for expansion and helps prevent overfilling. Larger voids should be completed in multiple layers.
