3、Causes and solutions
Causes | Solutions |
Improper coating method and uneven film thickness. | Strengthen operator training to maintain proper spraying speed, spraying distance, coating sequence and coating frequency. |
Before the paint is used, the settled pigment has not been stirred up or stirred insufficiently, resulting in a decrease in covering power. | Stir thoroughly before use and during coating process. |
The paint was not diluted in accordance with the construction process instructions during the paint dilution process. Then over-diluted or sprayed paint film is too thin. | Appropriately increase the construction viscosity or increase the number of sprays to increase the thickness of the paint film. |
The color contrast between the primer and topcoat is too great. | The color of the primer should be as close as possible to the color of the topcoat. |
