During the spraying operation, improper operation of the spray gun will affect the spraying effect of the product. A good spraying effect is shown in: 1. The coating is evenly distributed; 2. The coating cannot be too thick or too thin. The distance between the nozzle outlet and the object to be coated is called the gun distance. The smaller the gun distance, the greater the spraying pressure, and the greater the impact of the air pressure on the product, and the coating will be uneven, resulting in the problem of overly thick coating.


The larger the gun distance is, the smaller the spraying pressure is, and the paint is easily lost, so that the sprayed part of the object to be coated is too small, and the coating cannot reach the specified thickness. The spraying fan is in a vertical state with the surface to be coated. When manually operating the spray gun, the spray width cannot be too large, otherwise the problem of uneven coating will occur. The purpose of the spray gun operation should always be parallel to the surface of the object to be coated and perpendicular to the spraying fan surface.​​

All in all, when using spraying equipment, it is necessary to achieve moderate strength and appropriate distance, so that the desired coating effect can be obtained. After construction, some finishing things also need to be improved, and paint and help appliances are cleaned up. , the residual paint after use should be blocked and retained. This is a problem that needs attention.

The maintenance of the spray gun is nothing more than a few points:
1. If it is blocked, we will clean it.​​
2. No atomization, clean and check whether the air pressure is enough.　　
3. Intermittent, the paint may not be clean, there are air bubbles, and the paint needs to be filtered again.　　
4. As long as you don't break the spray gun yourself, you can solve the small problems of the spray gun yourself without changing the accessories.
