Abstract:
Laboratory evidence is presented to demonstrate that pretreatment is invaluable if not essential to the successful use of oil-base paints on concrete surfaces. An effective pretreatment is described as consisting of a water solution of 2 percent zinc chloride 3 percent phosphoric acid. With proper pretreatment, it is indicated that paint on concrete may last longer than paint on wood and that the customary extended aging period for concrete prior to painting may be omitted.
