Description: While these two terms are commonly used interchangeably because they serve the same purpose, they are indeed different. The main difference between sealants and caulks is elasticity. Caulks are relatively rigid when dry, and are recommended for application with minimal expansion and contractions. On the other hand, sealants are designed with flexible materials such as silicon that makes them ideal even for applications that are prone to expansion and contraction. If you opt to use caulks to seal your gaps, they are paintable and smears can be cleaned with water. However, their limited expansion makes them susceptible to cracking especially when the temperature swings. In the case of sealants, the smears can only be cleaned with a solvent.
