The problem of sagging and its solution

During the car repair spraying process, sagging (commonly known as "tears" or "paint hanging") refers to excessive accumulation of paint on vertical surfaces, causing the paint film to flow downward, forming strip-shaped paint flow marks. This not only affects the appearance, but may also cause uneven problems after the paint film dries. The following are the main causes of sagging and their solutions:

1.Spraying too thick

2.Gun air pressure is too low

3.The distance between the spray gun and the workpiece is too close

4.Incorrect spraying angle

5.Spraying speed is too slow

6.Improper diluent ratio

7.Effect of ambient temperature and humidity

8.Improper substrate preparation

Solution

1.Control spray thickness

2.Adjust the gun air pressure

3.Maintain proper spray gun distance

4.Adjust the spray angle

5.Control the spraying movement speed

6.Adjust paint ratio

7.Optimizing environmental conditions

8.Correct substrate preparation

9.Choosing the right solvent
