paint finishing forms two kinds of transparent (varnish) and opaque. The evaluation of finishing quality is carried out from the following aspects:

(1) the appearance color of the coating is transparent finishing. The appearance color should be bright and uniform, and the wood grain should be clear

(2) the surface shape of the paint film should be flat and smooth, without sagging, shrinkage, edge expansion, blistering, wrinkle and other finishing defects

(3) the polished surface of bright decoration should have mirror like luster without grinding defects, and the strict matte decorative surface should meet the required extinction degree. Opaque decoration requires the same as transparent decoration, except that the wood grain is not exposed, and the appearance color formed by the color paint film should be uniform and pure

(4) the paint film should reach a certain thickness and have high adhesion, wear resistance, cold resistance and temperature difference resistance
