Generally, caulk describes any waterproof material that fills and seals joints between building materials. It is used for both new construction and repairs. Caulks are typically made from a flexible polymer such as latex, silicone, rubber or any combination of the polymers. These materials are used because they are fully waterproof, can expand with temperature changes and absorb vibrations well.
Caulk and sealants come in cartridges or squeeze tubes. There are several types of caulk and sealants you can use inside and outside your building: latex caulk, silicone sealant, polyurethane foam and specialty caulks like butyl-rubber caulk.
“What is the difference between caulk and sealant?” is a question commonly asked. In fact, the terms “caulk” and “sealant” are often used interchangeably, since both are used to fill joints and seams. However, the biggest difference between caulk and sealant is elasticity.
Caulk is more rigid than sealants when dry. Sealants hold up better in spaces that are prone to a lot of expansion and contraction. For example, the best caulk for windows is usually a “sealant” instead of a true “caulk.” When choosing caulk vs. sealant for your project, decide based on how much stress there might be on the sealed area.
VMS stocks many caulks that can adhere to multiple surfaces and can connect materials on two different surfaces. For example; adhering glass to metal or granite.  Our Lexel brand of clear or white can adhere to virtually any surface whether wet or dry.
