Abstract
Abstract Water-based foam paints are provided in aerosol applicators. Water-soluble, non-toxic color additives are added to a foam-producing emulsion base to form a foam when the emulsion is sprayed from a conventional aerosol bomb. In the preferred embodiment, a system of three aerosol applicators corresponding to the three primary colors is utilized so that secondary colors can be created by mixing the appropriate portions of the primary colors.
