Product description
Soudal Trade Expanding Gun Foam – High-Performance PU Expanding Foam for Gap Filling & Insulation
The Soudal Trade Expanding Gun Foam is a professional-grade polyurethane expanding foam designed for gap filling, insulation, and sealing applications. Perfect for both trade professionals and DIY users, this high-yield expanding foam delivers excellent adhesion, thermal insulation, and acoustic performance across a wide range of building materials.
Engineered for precision application with a PU foam gun, it provides controlled expansion and maximum efficiency, making it ideal for window installation, door frames, roofing voids, and general construction sealing.
Key Uses & Applications
This versatile expanding foam insulation is ideal for:
- Installing windows and door frames
- Filling gaps, cracks, and cavities
- Sealing openings in roof constructions
- Improving thermal and acoustic insulation
- Internal and external building applications
Its strong adhesion to most construction materials makes it a go-to solution for professional sealing and insulation jobs.
Surface Preparation
For best results and maximum expansion performance:
- Remove dust, debris, grease, and contaminants using a brush
- Treat any organic growth with a suitable fungicide
- Lightly moisten surfaces with water to improve curing and expansion
Minimal preparation is required, but proper cleaning ensures optimal bonding and performance.
How to Apply Soudal Expanding Foam
- Shake the can thoroughly for at least 20 seconds before use
- Attach to a PU foam gun applicator securely
- Lightly dampen the surface to accelerate curing
- Hold the can upside down and fill approximately 65% of the void
- Allow expansion to complete the fill
- For multiple layers, let the first layer cure, then reapply with light moisture
This method ensures maximum expansion, efficiency, and a professional finish.
Limitations & Important Notes
- Cured foam must be removed mechanically
- Uncured foam can be cleaned with a damp cloth
- Always moisten surfaces to improve curing speed and foam performance
