GE Silicone I* All Purpose caulk can withstand all weather conditions, and will remain permanently waterproof, flexible, and shrink-/crack-proof. Outdoor elements such as heat, sun (UV rays), and extreme cold can cause acrylic to crack and crumble over time, leaving gaps for air and water to seep through. Those leaks can lead to water damage, mold growth, and higher energy bills.
TYPICAL USES: Windows, doors, siding, trim, molding, baseboards, vents, around wires/pipes, and other attic/basement applications
ADHERES TO: Most wood, metal, vinyl siding, drywall/plaster, glass, and plastic
