Cambridge Foam Sealant 12 oz – 1‑Component Expanding Polyurethane Spray Foam (Model 200583)

The Cambridge Model 200583 Foam Sealant is a 12‑oz one‑component expanding polyurethane spray foam, expertly engineered for sealing and insulating applications in both commercial and residential settings. With a high-expansion formula, it effectively fills cracks, gaps, voids, and spaces up to 1", forming a tight air, moisture, and pest barrier.

Ideal for a variety of substrates—including wood, concrete, metal, masonry, PVC, and fiberglass—this foam demonstrates excellent adhesion and structural integrity once cured. It sets to a semi-rigid consistency and can be trimmed, sanded, painted, or stained, making it suitable for finishing work.

The product is suitable for interior and exterior use, delivers a quick tack-free time (under 10 min), and achieves full cure in 1–2 hours depending on conditions. Packaged in a compact 12‑oz aerosol can with a spray straw, it’s easy to apply even in tight spaces. Contains no HCFCs/CFCs, making it environmentally preferable.
