In order to be more perfect and accurate, it is necessary to use sculpture technology to make up for the defects.

3. Primer: It fills the sand marks and micropores at the bottom of the workpiece, increases the adhesion of the lower coating, and also has the function of defect indication.

4. Intermediate primer: prepare a well-lubricated working surface for the top coat, complete the last procedure of all primer work, increase the adhesion of the participating layers and have a certain isolation effect to ensure the quality of the top coat is not chaotic.

5. Topcoat: Topcoat is divided into single-layer paint and multi-layer paint, which is a color fixing layer and a decorative maintenance layer.

The difference between furniture painting and automobile painting;

1, the furniture is painted with wood, and the car is painted with metal, which is resistant to high temperature. It is much more troublesome to paint cars than furniture.

2. Furniture is generally painted with ordinary paint and dried or cured at room temperature. Metal paint for automobile has a curing temperature above 100℃, high ultraviolet resistance, and is not easy to turn yellow, which is more expensive than ordinary paint.
