A sealant is a substance used to block the passage of fluids through the surface or joints or openings in materials.
Sealants and caulking also serve the purposes of blocking dust, sound and heat transmission.
Sealants may be weak or strong, flexible or rigid, permanent or temporary. Sealants are not adhesives but some have adhesive qualities and are called adhesive-sealants or structural sealants.
