The Soudafoam Genius Gun Gap Filler 750ml is a high-performance expanding polyurethane foam designed for filling, sealing, and insulating gaps, joints, and cavities. Featuring the innovative Genius Gun applicator, it provides precise, controlled application without the need for a separate foam gun, making it ideal for both DIY users and professionals.
Perfect for sealing around doors, windows, pipes, and cable entry points, the foam expands to fill irregular spaces, helping to improve insulation, reduce draughts, and minimise noise transmission. Once fully cured, it can be trimmed, sanded, and painted for a neat, professional finish.
