Product Information

SENTINEL 539 Sealer Encapsulant is a professional strength, low-odor, fast-drying sealer encapsulant used to seal and trap smoke and other odors commonly found on restoration projects.


SENTINEL 539 works great as part of a two-part system and should be used after affected areas have been cleaned. This sealer contains a fungistatic agent which inhibits the growth of mold and mildew on the dried surface of the sealer.




SENTINEL Formula 539 Smoke & Odor Encapsulant with Antimicrobial Protection is also available in a white finish.
