    What is the purpose of joint sealants?

    The integrity of a structure is often as good as the sealants used whenever two surfaces are joined together. Generally, joint sealants perform four basic functions: 

    • ​Prevent the passage of air, water and other environmental elements in or out of a structure
    • Accommodate movement of structures
    • Adhere to a wide variety of substrate materials to which they are applied to
    • Prevent the intrusion of solid materials which could block the joint space and prevent movement
