Overspray refers to a rough paint finish on the surface of the topcoat.
After application, excess paint is no longer absorbed on the newly sprayed surface, and the dried paint particles adhere to the new paint film.
Cause:
1. Insufficient thinner is used when mixing paint, and the viscosity of the paint is too high
2. The thinner dries too quickly
3.Using improper spray gun and tools
4. Improper construction technology, such as the spraying distance is too far and the spraying speed is too fast.
5. The temperature of construction environment is too high, etc
Prevention:
1. Mix the auto paint according to the ratio recommended in the technical data sheet;
2. Choose an appropriate thinner, such as a slow-drying thinner for hot and dry environments;
3. Accumulate spraying experience and improve construction technology skills such as spray gun technology;
4. If this phenomenon occurs, can deal with polishing. If the situation is serious, need to polish and then respray.
