① Brushing: When brushing with a paint brush, the brushing direction should be up and down first and then left and right, and the paint brush should not be dipped too much to prevent dripping. When painting heavy anticorrosive paint, the distance between paint brushes should not be too large to avoid the film being too thin. If the surface is rough, angular, protruding, etc. , pay special attention to, with * * first.
② Roller coating: When roller coating is used, the paint dipped on the roller should be evenly distributed. When painting, the rolling speed should be kept constant and not too fast. Don't push the drum too hard. Special attention should be paid to dents such as welds and incisions, and * * coating should be pre-coated.
③ High-pressure airless spraying: This is the fastest painting method, and a very thick paint film can be obtained. Therefore, in order to achieve the specified film thickness, airless spraying is adopted. In actual painting, vertical and horizontal spraying methods should be adopted, such as up and down before left and right or up and down before left and right. The use of lacquerless spraying requires high skills. The spray gun should keep a horizontal distance from the surface of the coated object, and the spray gun should be prevented from swinging in a long distance or in an arc shape during operation.
