A method for the removal and recovery of paint overspray in a water wash spray booth is disclosed. The method uses a circulating agitated dispersion of an organic solvent component in water which collects the paint overspray. The dispersion containing the overspray is permitted to phase separate into an organic phase and an aqueous phase. The organic phase is further treated such as by distillation to separate the paint solids from an organic solvent portion which contains the original organic solvent component and the organic solvents associated with the paint. The organic solvent portion can be recycled and reused in the circulating dispersion and the paint solids can be recovered for further use such as a filler for adhesives or can be disposed of.
