Supreme Silicone 10.1 oz. White Window and Door Caulk

By developing strength and adhesion quickly, Supreme Silicone window and door can be exposed to water in just 30 minutes. When using most caulks, the project may have to be delayed or canceled if rain is in the forecast. In fact, some caulk requires up to 24 hours or longer before it can be exposed to water. Otherwise, the caulk may wash away, wasting time and money. A shorter waiting period increases convenience, speed, and efficiency for consumers and pros. It also has extra flex and can withstand 2 times the joint movement of other top-selling silicone caulks for consumer applications. With +/- 50% joint movement, Supreme Silicone window and door can withstand extreme expansion or contraction that can occur with temperature fluctuations. Movement capability allows the caulk to move within the joint, helping to keep the caulk from tearing or pulling away from the substrate. This movement can cause degraded acrylic caulk 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. 100% silicone sealant is widely considered to be the best caulk for sealing areas that will be exposed to water.
