ABSTRACT:
A self-levelling continuous coating composition is disclosed. The composition is adapted for application on a surface of flooring material which contains asbestos. The composition encapsulates the hazardous material there in the floor and allows the addition of another layer of flooring to be installed thereover. The composition is comprised of about 40-55 parts by weight of a latex emulsion binder; about 2-7 parts by weight antifreeze; about 38-53 parts by weight hollow ceramic microspheres; and about 6-16 parts by weight water. The resulting composition can be applied in a single step application and does not require mixing of separate ingredients at the workplace.
