The selection of the coating method and the arrangement of the coating process can be summarized as the coating design, which is based on the clear coating purpose, the understanding of the properties of the substrate, and the coating theory. Process and other optimization combinations to achieve the complete planning of the expected coating quality

(i) Purpose or function of coating:

1. Protective effect

2. Decoration effect

3. Special function - color mark, adjust the environment, etc.

The purpose of painting is to first emphasize the protective effect, and then consider its decorative effect. If this is ignored, painting will be meaningless.

(ii) Classification of livery:

1. According to the degree of appearance of the wood grain of the substrate:

A. Clear coating (natural color)

B. Opaque coating (solid color)

C.Translucent coating

2. According to the gloss of the paint film:

A. Bright coating - gloss above 80%

B. Semi-gloss finish - gloss at 50±5%

C. Matte finish - gloss at 20±5%

D. Full matte finish - gloss below 10%.

3. According to the degree of appearance of wood eyes:

A. Fully enclosed coating

B. Semi-closed (semi-open) painting

C.Fully open paint

(iii) Influencing factors related to paint design:

1. The type of substrate to be coated

2. Properties of decorative materials (paints)

3. Painting technology level

4. Duration of construction period, working environment and site

5. Cost and grade effect.
