Description

GE Silicone II* Concrete & Masonry 100% Silicone THREE-HOUR RAIN-READY - Caulk has to have enough time to build adhesion to the surface and cure or dry adequately so it won't wash away when exposed to water. That means if rain is in the forecast, homeowners and pros typically will have to delay or cancel a project when using most caulks. If not, the rain might wash the caulk away and the job will have to be redone. Silicone caulk, such as GE Silicone II* Concrete & Masonry, develops strength and adhesion quickly so it can be exposed to water in as little as three hours. Some caulk requires up to 24 hours or longer before it can be exposed to water. For homeowners trying to squeeze home maintenance projects into the weekend or pros who are looking to move to the next job, GE Silicone II* can decrease the waiting time, helping increase convenience, speed and efficiency. SUN-/FREEZE-PROOF - The outside of a home is exposed to harsh outdoor elements throughout the year. Extreme heat, the sun's UV rays and freezing temperatures can cause acrylic caulk to lose its flexibility and degrade. The permanent flexibility of GE Silicone II* keeps it from breaking down so it can protect a home over time. Degraded acrylic caulk can 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. Why 100 percent silicone? Unlike acrylic, silicone is permanently: WaterproofAcrylic breaks down in water over time. FlexibleAcrylic becomes less flexible and can even freeze at low temperatures, making it more likely to crack. Shrink-proofAcrylic shrinks as the caulk dries. This shrinking can cause cracks over time. Crack-proofAcrylic hardens, cracks and crumbles over time when exposed to extreme heat and the sun's UV rays. Made in USA.
