Abstract

The invention is an improved process for denaturing and coagulating paint in an aqueous medium in which denatured and coagulated paint must remain in a dispersion in the aqueous medium. The aqueous medium contains a coagulant and the aqueous medium is maintained at an alkaline earth metal ion equivalent of less than 1.0 mmole/liter.
