Expanding Foam – Gun Grade – Indoor & Outdoor Use

Product Overview

Our professional-grade expanding foam is available in a 750ml canister, designed for use with gun applicators. This polyurethane-based foam expands up to 50 times its original volume, forming a dense, medium-fine cell structure that effectively fills, seals, and insulates cavities and gaps.

The formulation cures rapidly, becoming tack-free in around 8 minutes and ready for cutting or plastering within approximately one hour. This ensures an efficient, clean, and controllable application process.

This foam offers strong adhesion to a wide range of construction materials, including concrete, brick, plaster, timber, and metal, making it highly versatile across building and installation tasks. Its cured bead provides long-term load-bearing stability after about 12 hours and remains resilient to temperature fluctuations and moisture exposure.

It provides thermal conductivity of 0.04 W/mK and demonstrates excellent sound-deadening properties, improving both energy efficiency and acoustic insulation. Specifically designed for use with gun foam applicators, it delivers accurate dosing and reduced waste during application.

The cured foam withstands long-term temperature ranges between -40 °C and +80 °C, with short-term exposure up to +100 °C, ensuring stability and durability under varying environmental conditions. The 750ml can yields approximately 37 litres of expanded foam when fully cured.

Features & Benefits

• Quick Setting Time: Cures within approximately one hour, allowing the filled area to be cut, sawn, or plastered shortly after application.
• High Expansion Rate: Expands up to 50 times its can volume, enabling effective filling of wide or irregular cavities with minimal material use.
• Excellent Adhesion: Bonds securely to common building materials including wood, metal, brick, stone, and concrete, ensuring reliable structural support.
• Thermal and Acoustic Insulation: Provides a thermal conductivity of 0.04 W/mK and reduces sound transmission through filled voids and joints.
• Durable and Stable: Maintains full load-bearing performance after 12 hours and resists degradation across a broad temperature range from -40 °C to +100 °C (short-term).
• Controlled Application: Formulated for use with professional gun applicators, allowing precision control, reduced overspray, and cleaner results.
• Can Size – 750ml: Expands to approximately 37 litres of cured foam, suitable for extensive sealing and insulation work.

Applications

• Gap Filling: Ideal for sealing around pipe penetrations, window frames, door frames, and irregular masonry voids.
• Framework Fixing: Used to anchor door and window frames.
