A process which allows elastomeric materials of different colors, durometers and/or other material characteristics to chemically bond to one another so as to eliminate any possibility of delamination. Latex-based liquid elastomer solutions having different material characteristics are applied sequentially to a heated mold to form a series of layers making up the article, with rapid partial curing taking place between each application; the partial curing forms a skin coat over each layer which prevents intermixing of the different solutions, but which still permits a chemical bond to form during full curing of the materials. The process applies equally to dip (immersion) molded and flat molded goods. An example of the invention as it relates to flat-molded goods is an athletic shoe sole, and an example as it relates to dip-molded goods is a resilient, one piece watersports boot which can be fitted over a human foot without a zipper.
