OSI Quad sealant is a versatile, all-weather caulk designed for window, door, siding, gutter and roof applications. This advanced formula stays flexible across temperature ranges, ensuring reliable performance in both hot and cold weather. It adheres without primer to most common building materials, including vinyl, aluminum, steel, wood, fiberglass, fiber cement board, masonry, concrete, brick, glass and plastics, making it ideal for both new construction and renovation projects.
The sealant is engineered for superior adhesion and easy extrusion even in cold weather, eliminating common application frustrations.
