Everbuild Expanding Foam Gun Grade 750ml

Everbuild Gun Grade Expanding Foam supplied in a 750ml canister is a professional polyurethane-based expanding foam designed for use with gun applicators. It 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, tack-free in around 8 minutes and ready for cutting or plastering within approximately one hour, offering an efficient, clean, and controllable application process. This foam provides 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 delivers long-term load-bearing stability after around 12 hours and remains resilient to both temperature fluctuation 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. Designed specifically 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, and 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.
