Learn About Asbestos Sealing and How it is Used to Bind the Fibers
Encapsulation: Treating Asbestos Material by Sealing the Fibers Together Asbestos sealing (encapsulation) involves treating the material with a sealant that either binds the asbestos fibers together or coats the material so fibers are not released. Pipe, furnace, and boiler insulation can sometimes be repaired this way. This should be done only by a professional trained to handle asbestos safely.
