Abstract: A method of encapsulating and providing barrier containment for asbestos which forms an integral part of existing building structures includes applying an encapsulating coating comprising a water soluble polyvinyl acetate emulsion to the exterior surface of the structure. The encapsulating coating is dried to permit maximum penetration and encapsulation prior to performing subsequent steps which may disturb the asbestos fibers in the surface of the building structure. A primer coating comprising a stronger formulation of polyvinyl acetate emulsion is applied to the structure surface. An adhesive coating comprising the stronger formulation of the polyvinyl acetate emulsion is applied to the gypsum side of a sheet of a surface covering product that comprises a substantially dry, semi-hydrated gypsum. The sheet of gypsum product is applied to the surface of the structure by contacting the primer and adhesive coatings with one another.
