Older versions of ASTM D2092 suggested allowing galvanized steel to weather outdoors for 6–12 months before painting. because:

This is the most common industrial method. It involves applying a zinc phosphate solution that reacts with the surface to form a crystalline layer, providing an excellent mechanical "tooth" for the paint. The ASTM D2092 PDF document includes the following

The status of ASTM D2092 is complicated. The standard guide for painting has been by other standards, such as ASTM D3794 - Standard Guide for Testing Coil Coatings. However, ASTM D2092 remains a highly referenced and historically significant document. Many industries and specifications still call it out by name, and obtaining the last active version (e.g., D2092-95) is often necessary for compliance with legacy contracts or internal quality systems.

Apply the acidic solution directly to a clean zinc surface to micro-etch the metal and passivate it simultaneously. Older versions of ASTM D2092 suggested allowing galvanized

Implementing ASTM D2092 requires identifying the current state of the galvanized surface, which generally falls into three categories: Galvanized Surface State Characteristics Recommended ASTM D2092 Action

The galvanized steel is treated with a hexavalent or trivalent chromium solution.
