Great Stuff Wide Spray is a closed cell insulating foam sealant that coats and air-seals seams, joints, large gaps, and irregular surfaces (up to 6 in. wide). Wide Spray provides broad coverage, fast application and reach, allowing for rapid air sealing over large surfaces, in tight spaces, hard-to-reach areas, and adheres to vertical and horizontal surfaces. Wide Spray comes with two 18oz cans and can cover up to 60 linear ft. (at a 4 in. wide band). The 1-component formulation means no mixing and requires no respirators or coveralls while spraying. Great Stuff Wide Spray expands to take the shape of cracks and voids and forms a durable, airtight and water-resistant bond that eliminates unwanted airflow and helps reduce condensation.
