Product Properties

  • Type Sealants and Mastics


SENTINEL® Universal Sealant can be applied using a standard caulking gun or pneumatic cartridge applicator. Apply a 3/8” bead to surfaces free of any dirt and debris or other contaminants that may prohibit adhesion. Tooling of the bead of sealant may be needed to ensure maximum adhesion and to shed water from the detail. Petroleum solvents will negatively affect adhesion if used to clean the substrate.
