Expanding Foam – Gun Grade – Indoor & Outdoor Use

Product Overview

Our Professional Expanding Foam in a 750ml canister is a versatile, one-component polyurethane foam designed for gap filling, sealing, and insulation. The moisture-curing formula expands upon application to create a stable, rigid structure that adheres to most common building materials such as brick, concrete, timber, plaster, and metal. Suitable for non-fire-critical areas, it offers reliable performance in construction and maintenance tasks.

Once cured, the foam can be cut, sanded, plastered, and painted for precise adjustment and a neat finish. Its closed-cell structure ensures resistance to shrinkage and maintains dimensional stability even when applied overhead, contributing to thermal and acoustic insulation by reducing heat loss and noise transmission.

The 750ml canister is designed for use with a professional foam applicator gun, offering precise flow control, adjustable output, and reduced waste during application. The gun-grade format enhances accuracy and efficiency for larger or repeated installations.
