A long lasting primerless, paintable, Kraton G® block copolymer based, elastomeric sealant. When used as directed, the material will seal joints or cracks to resist the passage of light, heat, cold, air, snow, wind, odor, dust and chemical contaminants. Material has a 30 year life expectancy.

Highly recommended for commercial or residential buildings and their roofs, walls, and window openings. The product adheres to brick, glass, wood, copper, concrete, fiberglass, steel, aluminum, and most plastics, in wet or dry conditions.
