Sealants are special materials used to fill gaps and cracks in various surfaces, helping to prevent water, air, and dirt from entering. They are commonly applied in construction and home improvement projects, especially around windows, doors, and roofs. By sealing these areas, sealants protect buildings from damage caused by moisture and improve energy efficiency. There are different types of sealants, including silicone, latex, and polyurethane. Each type has its own unique properties, making them suitable for specific applications. For example, silicone sealants are great for areas exposed to water, while latex sealants are easier to clean up and paint over.
