The Cleaning Institute

Most homeowners are well aware of the importance of using caulk to seal holes and cracks that form, as well as limit the amount of cold or warm air that transfers out of the house. Caulk is useful in increasing the energy efficiency on the property and is easy to apply without the help of a professional contractor. Our team reviewed many types of caulk products to ensure we could provide our consumers with a few of the top picks. Our top pick is the Flex Shot Rubber Adhesive Sealant Caulk, because it bonds and seals virtually everything. It’s also convenient to use because it doesn’t require the use of a caulking gun to apply. The Gorilla Clear 100 Percent Silicone Sealant Caulk is named our honorable mention because of its versatility and ability to dry clear. We also suggest trying the Food Grade NSF FDA RTV Silicone Sealant Adhesive, because it’s a non-slump silicone paste which has excellent resistance to extreme temperatures, ozone, moisture, vibration, and weathering.
