This guide describes procedures that can be used to prepare new zinc-coated surfaces for painting and improve the bond of paint to the zinc surface.
1.1 This guide covers surface cleaning and various methods of treating new zinc-coated by the continuous process (galvanized) surfaces produced by either the hot-dip method or by electroplating. This guide covers surfaces that have not been treated previously at the mill to provide temporary protection against staining by moisture other than by easily removed protective oils (see Appendix X1). For preparing surfaces of new or weathered items of zinc-coated steel produced by batch processing, refer to Practice D 6386
