There is a small pit of millet after the door is brushed.
There are three reasons why a pit the size of a small grain of rice appears after the door is brushed. The first is that there is no putty leveling before painting, which leads to uneven spraying position. When the paint dries, these uneven positions will become very obvious. The second reason is that when the paint is wet or water is added, even if a drop of water enters the paint, pits will appear on the painted leather surface, so don't inject water when shunting the paint. The third reason is that the paint was not wiped with degreasing agent before painting, and the paint could not adhere to the greasy paint surface, thus forming a small pit the size of rice grains.
How to avoid paint leakage when spraying varnish in winter?
First of all, when painting, check the viscosity of the paint. If the viscosity is too high, the spray is not flat enough; If the viscosity is too low, the adhesion is too poor. Secondly, the adjustment of spray gun is also very important, so it is necessary to pay attention to the collocation of spray valve and valve, which has a great influence on the quality of spray painting. Finally, choose a quiet room when painting, and never paint in windy conditions, otherwise the paint flow problem will be more serious.
