Poor car paint coverage
Also known as translucent or bleed. The color paint cannot completely cover the color of the original paint surface, or the color of the old paint film and the color of the primer layer penetrate into the top paint layer, changing the color of the top paint. The red and yellow paint layers show more bleeding.
(1) Cause:
①Precipitation occurs in the paint. After the topcoat is diluted, without adequate stirring, the pigment is deposited on the bottom of the container, resulting in too high resin content in the sprayed paint and lighter color.
② Wrong spraying technology. For example, each subsequent coat was not reapplied, resulting in stripes or poor coverage.
③ Too much thinner is used, making the paint coating very thin.
④ The old paint layer or the bottom coating contains pigments that can cause bleeding, so the old paint layer should be handled with care, and an isolation layer that can prevent bleeding can be sprayed.
(2) Correction method:
If there is slight bleeding, spray enough paint to cover. For heavily bleeding paint, it should be sanded off and repainted.
