Sealing Exterior Surfaces in the Summer Sun



So… it’s officially the first day of summer and the longest day of the year.

While there is much in that to be celebrated, it is also another reason to choose your caulking materials carefully. Especially if you are sealing exterior surfaces. 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. 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.

Even though longer exposure to the Summer Sun will bring a smile to most faces, it will also bring more wear and tear to your sealed surfaces. This is why you will want to choose a good exterior grade silicone sealant for all of your exterior applications.
