Description
Bostik Expanda Foam (350g/350ml) is a high-performance, one-component, multi-purpose polyurethane expanding foam designed to seal, fill, bond, and insulate gaps and cavities.
Key Features: It cures into an airtight, moisture-resistant, and waterproof seal that will not shrink over time. It provides excellent thermal insulation against heat/cold and significantly reduces noise, dust, draughts, and pest access.
Application & Finish: Supplied with a convenient straw adapter for easy application at any angle. Once fully cured (12–24 hours), the foam can be cleanly cut, sanded, plastered, or painted.
Adhesion: Bonds powerfully to timber, brick, concrete, galvanized steel, aluminum, glass, fiber cement, and plasterboard.
Usage: Suitable for both interior and exterior applications, such as filling around window and door frames, pipe penetrations, and wall cavities.
