Joint sealants are used to seal joints and openings (gaps) between two or more substrates, and are a critical component for building design and construction. The main purpose of sealants is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates. While sealants may seem like a small detail item on your building, they can contribute to the development of large problems if they fail and allow moisture to get into the walls. ARDEX ENDURA offers excellent solutions for all these requirements
