Great Stuff Multipurpose Black Insulating Foam Sealant is a ready to use, minimal expansion polyurethane insulating foam sealant that fills, seals and insulates gaps up to 3/4 in. It expands to take the shape of gaps, creating a long lasting, airtight and water resistant seal. The black color blends naturally into the surrounding environment and allows cured foam to hide well and not be noticeable in shadows. New Smart Dispenser design eliminates mess and product waste by providing a precise application with no drips. The application is maneuverable and intuitive to use with a simple, trigger gun which saves time. The Smart Dispenser allows the user to reuse Great Stuff for up to 30 days.
