1. You can choose the color of the paint according to your preference. It is recommended to use alkyd primer as the base and alkyd topcoat to cover the surface.

2. The galvanized sheet does not need any processing and can be directly sprayed with an air compressor + spray gun.

3. For outdoor use, it is recommended to use iron red anti-rust paint or medium gray anti-rust paint.

4. Let it dry naturally outdoors. If conditions permit, galvanized parts can be phosphated, or a thin layer of phosphating primer can be sprayed first. Or sand the surface of smooth galvanized parts. Wipe the surface of galvanized workpieces and galvanized pipes with solvent (i.e. epoxy zinc yellow primer diluent) to remove the protective layer of crude oil on the workpiece and increase cleanliness.

Two-component epoxy zinc yellow primer: Prepare the paint strictly according to the ratio of paint and curing agent, and after curing for 30 minutes, adjust the appropriate construction viscosity before spraying. One-component epoxy ester zinc yellow primer: adjust the appropriate construction viscosity and apply it with the correct construction method.

Galvanized parts are non-ferrous metals, and non-ferrous metals have poorer adhesion than black all-metal. Commonly used alkyd iron red primers and epoxy iron red primers on the market are not suitable for use on galvanized parts, otherwise they will easily fall off.
