Appendix A
Construction reference
(reference)
A1 Before painting, remove the rust and oil stains on the metal surface, and then apply a layer of phosphating primer. Before construction, the paint must be stirred evenly and diluted with a mixed solvent of xylene and butanol. It can be applied by spraying or brushing. After the paint film is dry, it should be polished with water sandpaper, and then putty or topcoat can be applied after it is dry.
Products that exceed the storage period can be inspected according to this standard. If they meet the technical requirements, they can still be used. A2
