Sika Gun Grade Expanding Foam

Achieve professional-grade accuracy and strong, long-lasting results with Sika Gun Grade Expanding Foam. Designed for use with a foam applicator gun, this high-performance polyurethane foam provides superior control, reduced waste, and a cleaner application compared to traditional hand-held cans.

Sika’s advanced gun-grade formula expands to fill gaps, cracks, cavities, and voids, forming a tough, durable seal with excellent thermal and acoustic insulation properties. It adheres to most common building materials, including brick, concrete, metal, timber, plaster, and plastics.

Once cured, the foam can be cut, trimmed, sanded, plastered, and painted, making it ideal for both first-fix and finishing work. Perfect for professional tradespeople such as builders, joiners, plumbers, and window installers.
