Foam Sealant Soudal GENIUS GUN 750 ml — polyurethane application foam, 750ml cartridge

Soudal GENIUS GUN 750 ml is a one-component polyurethane application foam supplied in a 750 ml cartridge for use with a dispensing gun. It is formulated for filling, sealing and insulating gaps and joints in building and renovation work. The foam cures to a closed-cell structure that provides adhesive bonding as well as thermal and acoustic insulation, making it suitable for perimeter sealing around windows and doors, filling cavities and sealing pipe penetrations.

Advantages

The product offers controlled dispensing when used with a compatible foam gun, enabling precise application and reduced waste. It provides good adhesion to common construction substrates such as concrete, brick, wood and metal without the need for a primer on many surfaces. After curing, the closed-cell foam has low water absorption and contributes to thermal insulation and sound reduction. The cartridge format is suitable for trade and professional use where larger volumes are required.

Suitable for

• Sealing and insulating gaps around window and door frames
• Filling cavities and voids in walls and floors
• Sealing penetrations for pipes, ducts and cables
• Bonding lightweight building elements and panels

Key specifications

• Formulation: one-component polyurethane foam
• Application method: cartridge for use with a dispensing gun
• Volume: 750 ml
• Cell structure after curing: predominantly closed-cell
• Properties: adhesive bonding, thermal insulation, acoustic insulation, low water absorption after curing

How to use

Prepare surfaces by ensuring they are clean, dust-free and free from loose material and grease. Fit the 750 ml cartridge into a compatible dispensing gun and attach the application nozzle. Apply foam from the bottom of the gap and move the nozzle to fill the cavity progressively, allowing for foam expansion. After application, trim excess cured foam with a knife and, if required, finish with sealant, plaster or paint following manufacturer surface preparation recommendations. Observe curing times which depend on temperature and humidity.

Usage recommendations

Store cartridges upright in a cool, dry place and protect from direct sunlight and temperatures outside the recommended range. Use personal protective equipment such as gloves and eye protection during application. For best results, use Soudal GENIUS GUN 750 ml with a suitable professional foam gun and follow local regulations for ventilation and waste disposal.
