The main difference between a sealant and caulking is flexibility. Caulking fills gaps and cracks in areas with minimal movement, while sealant remains flexible to handle joint expansion and contraction. Sealants, such as silicone, are used in high-moisture or shifting areas, whereas caulk is best for trim and molding.
Sealants and caulking are both used to fill gaps and prevent the passage of air, water, or other substances. The primary difference is that sealants are generally more flexible and durable, making them suitable for areas that experience movement or expansion, such as joints in building materials. Caulking, on the other hand, is often used for aesthetic purposes or to fill small gaps and cracks in stationary areas, like around windows or baseboards, and may not be as elastic as sealants.
