Bad Hiding Power after sprayed car paint?

Source:本站    Release time:2022-12-06 10:56:32    Click volume:

The main function of the automotive paint is to make the object to be painted colored, and to have hiding power on the surface of the product. But sometimes when doing the paint construction, you will encounter poor hiding power. The new color paint layer cannot completely cover the original paint color, or the color of the old paint film has penetrated into the top coat layer, changing the sprayed new top coat color. So what is the reason?


1. Precipitation of the color auto paint. After the paint is diluted, it is not stirred sufficiently, and the pigment is deposited at the bottom of the container, resulting in excessive resin content in the sprayed paint and lightening of the color.


2. The hiding power of the paint used is not a high covering pigment.


3. The spraying method is wrong, the paint film is too thin, and the number of layers is few.


4. The ratio between color paint and thinner is wrong, too much thinner will make the paint coating very thin.


5. Grinding and excessive polishing reduce the thickness of the paint layer.

Of course, it may also be due to inadvertent spraying or the complex shape of the object being coated, resulting in missing spraying coatings. So how to remedy the situation of insufficient covering power?


If there is slight bleeding, enough paint can be sprayed to cover it;


If the bleeding is serious, the defective area needs to be polished, and a high-quality paint should be selected for repainting.
