Pattex PU Foam Fix & Fill is a versatile expanding polyurethane foam designed to deliver high-quality sealing, filling, and insulating performance for a wide range of construction, repair, and installation tasks. Formulated for both professional and DIY users, this foam provides exceptional expansion and strong adhesion to multiple building materials, making it a dependable solution for projects that require durability and precision.
The foam expands upon application to effectively fill gaps, voids, cracks, and cavities, creating a firm and stable structure that prevents air leakage, water penetration, dust infiltration, and noise transmission. It adheres securely to surfaces such as wood, brick, concrete, plaster, metal, and PVC. This makes Pattex PU Foam Fix & Fill particularly useful for installing and sealing window and door frames, insulating pipe penetrations, filling wall openings, and reinforcing roof junctions.
With its high-yield formula, the product offers excellent coverage, making it ideal for both small household repairs and larger construction projects. Once cured, the foam becomes rigid, weather-resistant, and long-lasting, maintaining its shape without shrinking or cracking over time. It can be easily cut, shaped, sanded, and painted to achieve a clean, finished look that blends seamlessly with surrounding surfaces.
Pattex PU Foam Fix & Fill is user-friendly and designed for smooth and controlled application with a standard foam gun or applicator. Its fast-curing properties enable quicker project completion without compromising bond strength or insulation performance.
Whether you are sealing gaps around windows, filling wall cavities, improving home insulation, or handling detailed installation work, Pattex PU Foam Fix & Fill provides consistent and dependable results. Its strength, versatility, and ease of use make it an essential foam product for enhancing energy efficiency, structural reliability, and overall construction quality in residential, commercial, and industrial environments.
