A method and formulation for separating airborne overspray mists of paint and lacquer from ambients which includes the steps of exposing the mist to an aqueous solution of a deactivating formulation, permitting the contact to continue until the paint has become deactivated, and thereafter separating the deactivated paint from the aqueous solution. The formulation which comprises the aqueous solution includes an alkaline agent consisting of calcium hydroxide, sodium metasilicate, and mixtures thereof, bentonite clay, an aliphatic petroleum distillate having a lower boiling point of greater than about 150 DEG C., and a fatty acid nitrogen derivative selected from the group consisting of primary, tertiary, 1,3-propylenediamines, and quaternary ammonium chlorides, each with a fatty carbon chain length of from 10 to 18 carbon atoms. The formulations of the present invention are effective for deactivating and removing paint overspray of a variety of compositions, including both oil base and latex type paints, as well as epoxy and polyurethane base paints.
