Do I need to finish painting before making a closed painted wooden door?

1. Sealing paint is a painting process, and its main feature is that the brown holes on the wood surface are completely closed by paint. Its main component is unsaturated resin with high concentration, indicating that the coating on the surface of furniture is plump, thick, bright and smooth. This painting process is widely used in furniture on the market now.

2. The basic process flow of sealing paint is: grinding-primer-grinding-background color-secondary primer-grinding-surface color change-topcoat.

3. The sealing primer plays the role of fiber conduit for sealing the pores of the substrate, and it is gelatinous to form a film, which is not easy to polish. Generally diluted, the viscosity is still high. The secondary primer is generally thick, which is convenient for polishing and leveling. By making the background color and top color, the surface can be smoother and brighter.
