1.1 This guide covers surface cleaning and various methods for treating new, continuous zinc-coated (galvanized) steel surfaces produced by either the hot-dip method or by electroplating. This guide is applicable to only surface preparation for application of liquid paint and coating products, and not for powder coating applications. 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 D6386.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


4.1 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.
