For many years sprayed metal coatings have been generally regarded as being undercoats for paint systems on iron and steel surfaces, thin coatings of zinc, aluminium or zinc aluminium alloy being applied to increase the adhesion of the paint and to prevent corrosion at the paint/base metal interface. This mode of practice was probably logical when the paint formulations changed to the use of the more resistant resins such as epoxides and before the need for adequate surface preparation was accepted. Sprayed metal coatings have always needed adequate surface preparation as an integral part of their application, so that understandably the good performance in service of such thin metal coatings followed by the application of these resistant paints encouraged the use of cognate coatings, as they represented a measure of insurance against premature failure.
