Product details
Description
Transform your home insulation and construction projects with this advanced single-component polyurethane foam designed to fill, seal, and insulate large gaps with ease. Expanding up to three times its original size during the curing process, this moisture-curing straw foam reaches deep into awkward cavities, roof openings, and hard-to-reach structural cracks.
It forms a robust, permanent bond with standard building materials like wood, concrete, stone, and metal, delivering stellar thermal and acoustic isolation. Once fully cured, the durable formula resists mildew and water while remaining completely paintable and sandable for a clean, professional finish.
How to use
- Shake the aerosol can vigorously before application.
- Attach the straw nozzle to the valve, invert the container, and apply the foam sparingly into the gap or cavity, accounting for its triple-expansion property.
- Allow it to cure fully via air humidity before trimming, sanding, or painting over the surface.
