Expanding Foam – Polyurethane – Indoor & Outdoor Use

Product Overview

This Heavy Duty Expanding Foam in a 750ml canister is designed for general-purpose gap filling, sealing, and insulation. It features a moisture-curing formula that expands upon application, forming a stable, rigid structure. This foam adheres to most common building materials, including brick, concrete, timber, plaster, and metal, providing reliable performance in everyday construction and maintenance work.

Once cured, the foam can be cut, sanded, plastered, and painted, ensuring a precise and neat appearance. Its closed-cell structure prevents shrinkage or post-expansion, maintaining dimensional stability even in overhead applications. Additionally, the cured foam enhances both thermal and acoustic insulation, reducing heat loss and noise transmission through gaps, joints, and cavities.

The 750ml canister comes with an integrated application straw, allowing controlled, one-handed use without additional tools. This design ensures accurate placement and easy operation for efficient on-site or domestic applications.
