GE Supreme Silicone Window and Door sealant is a 100% waterproof sealant that can provide a reliable seal in weather-prone areas such as windows, doors, basements, roofs, sidewalks, siding, tuckpointing, and attics. Our sealant also has a 30-minute rain ready formula and resists stain causing mold and mildew growth. This 100% silicone sealant offers 40% more flexibility than Class 25 sealants and 7X stronger adhesion than our Silicone 1 sealant. Plus, it offers 50% joint-movement capabilities without cracking, shrinking, breaking down, or washing away. GE Supreme Silicone Window and Door sealant has a low odor that's ideal for interior applications, and it won't discolor most high-end metal finishes such as chrome, bronze, and nickel.
