Great Stuff Pro Series Gaps & Cracks Gun Foam, 24 oz.

Great Stuff Pro Series Gaps & Cracks Gun Foam, 24 oz. is designed to reduce drafts and save energy by sealing gaps and cracks up to 3 inches in diameter. This ready-to-use insulating foam expands to fill the shape of openings, creating a heavy-duty, fire-blocking seal that enhances comfort and safety. Applied with a foam-dispensing gun, it offers greater precision and access to hard-to-reach areas. The can is reusable for up to 30 days, helping to minimize waste. This fireblock sealant adheres to wood, vinyl, metal, and other building materials, forming a long-lasting, airtight, and water-resistant barrier that helps keep out moisture, condensation, and allergens. It becomes tack-free in 3 to 10 minutes and can be trimmed in one hour. Suitable for both indoor and outdoor use, it is paintable, stainable, and sandable for a seamless finish.
