| GE 100% Silicone I 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.
Unlike acrylic, silicone is permanently waterproof, flexible, shrink-proof, and crack-proof. When cured, the color is white.
