This product creates a long-lasting barrier that?helps prevent the release of particulates, which can irritate breathing and carry strong odors. When offensive particulate matter is encapsulated and sealed away, overall air quality and occupant comfort are improved. Unsoot #1 can be applied to structural wood, duct work, or ceiling plenums. It can also be combined with odor control agents to give it additional odor-control capability.
