The roughness of the newly sprayed car paint may be caused by the following reasons:
1. The painting environment is not clean: there are dust, particles or other impurities in the air, which fall on the auto paint surface during painting, resulting in a rough paint surface.
2. Problems with spraying equipment: The nozzle of the spray gun is clogged or the spraying pressure is uneven, resulting in uneven paint surface, which leads to a rough feeling.
3. Automotive Refinish Paint quality issues: using low quality paint or the paint is not fully stirred, resulting in poor spraying effect.
4. Spraying technology problems: incorrect spraying techniques, such as inappropriate spraying distance, uneven spraying speed, etc.
5. Drying process problems: Poor drying environment after painting, such as too high or too low temperature, poor air flow, will affect the flatness of the automotive paint surface.
6. Improper primer treatment: If the primer is not completely dry or polished before the topcoat is applied, the final paint effect will be affected.
To avoid these problems, it is necessary to ensure the cleanliness of the painting environment, use high-quality car paint and spraying equipment and materials, master the correct spraying technology, and dry under appropriate conditions.
