The shelf life of water based metallic paint is generally 3 to 7 years. For ordinary industrial environments, the anti-corrosion validity period of water based metallic paint coatings is usually between 3 and 5 years; for marine environments and highly corrosive climates, the shelf life of the coating may be slightly shorter, generally 2 to 4 years.

Whether metallic water based paint can cover old paint depends on two main factors: the type of old paint (whether it is water-based paint or solvent-based paint) and the surface condition of the old paint. Generally speaking, metallic water based paint can cover old paint, but it must be ensured that the old paint layer is in good condition and has not fallen off, cracked or severely peeled off.

Water-based metallic paint usually requires a good adhesion foundation, so the effect of the paint on wood may not be as ideal as on metal surfaces. In particular, the humidity fluctuations and texture changes of wood may affect the stability of the coating.
