Soudal Trade Gap Filler Foam Genius Gun 600ml Expanding PU Foam | 135234

General-Purpose Expanding Foam with Reusable Genius Gun® Applicator

The Soudal Trade Gap Filler Foam Genius 600ml is a professional moisture-curing polyurethane expanding foam designed for filling, sealing and insulating holes, gaps, voids and joints throughout general building and construction work.

It combines high filling capacity with excellent thermal and acoustic insulation, adhering to most common building materials and providing resistance to water, heat and ageing. Once fully cured, the foam can be cut, sanded, plastered and painted to achieve a neat finished installation.

A major advantage is Soudal's patented Genius Gun® applicator, which provides controlled, single-handed application without requiring a separate professional foam gun. The applicator is also resealable, allowing the can to be reused for up to six weeks after first use when correctly stored.

Soudal describes the product as a general-purpose gap-filling foam offering high thermal and acoustic insulation together with high gap-filling yield.

Patented Genius Gun® Applicator

The standout feature of this Soudal expanding foam is the Genius Gun® application system.

Unlike traditional hand-held foams with a basic straw applicator, the patented trigger mechanism is designed to provide easy, controlled and precise single-handed application.

This makes it particularly convenient for tradespeople who need the control of a purpose-designed applicator without carrying a separate PU foam gun.

Reusable for Up to 6 Weeks

The Genius Gun® system also incorporates a resealable applicator.

When correctly resealed and stored after use, Soudal states that the product can be reused for up to six weeks after its first application.

This can significantly reduce waste where only part of the can is required for a job, making it particularly useful for maintenance teams and tradespeople carrying out multiple smaller filling and insulation tasks.

High Gap-Filling Yield

The 600ml aerosol provides excellent filling performance.

Soudal's technical data specifies an approximate free foam yield of 22 litres from the 600ml can, with a stated joint yield of approximately 14 metres under the manufacturer's test conditions.

This high filling capacity makes the foam suitable for tackling everything from small gaps to larger construction voids.

Thermal & Acoustic Insulation

In addition to filling gaps, the cured polyurethane foam provides effective thermal and acoustic insulation.

Soudal's technical data specifies:

• Sound Insulation: 58dB
• Thermal Conductivity / Insulation Factor: 37mW/m.K

This makes the foam useful around building penetrations, frames, pipes and other areas where reducing heat transfer and sound transmission is beneficial.

Ideal Around Windows & Doors

Soudal identifies window and door frames as one of the applications for Trade Gap Filler Foam Genius.

The expanding foam fills irregular spaces around frames, helping close gaps and provide additional thermal and acoustic insulation around the installation.

Correct installation practices should always be followed, particularly where movement, structural fixing or specialist fire/acoustic performance is required.

Excellent Adhesion to Building Materials

The foam adheres to most common construction substrates, making it highly versatile for general building work.

Soudal's technical information states that it offers good adhesion to most surfaces, with PE, PP and PTFE specifically excluded.

This broad compatibility makes it useful for filling and insulating a wide range of construction gaps and cavities.

Easy to Finish After Curing

Once completely cured, Soudal Trade Gap Filler Foam can be:

• Cut
• Trimmed
• Sanded
• Plastered
• Painted

This allows excess material to be removed and the filled area finished to suit the surrounding construction.

The cured foam is not UV resistant, so exposed foam should be covered with a suitable sealant, paint, plaster or other appropriate finish.

How to Apply

Shake the can thoroughly for at least 30 seconds before use. Open the cover and unfold the Genius Gun® tube into its horizontal operating position.

Hold the aerosol upside down while dispensing and only partially fill the gap – Soudal recommends approximately one-third of the available space to allow for expansion.

Regularly shake the can during application. Slightly moistening the substrate can accelerate curing and improve the foam's cellular structure. When building up multiple layers, repeat the moistening process between layers.

For storage after use, reseal the nozzle according to Soudal's instructions and store the aerosol upright.
