Matte paint is more difficult to serve than ordinary paint ~ There are many factors that cause this phenomenon.

1, the distance is too far (the best effect of normal pen/sprinkler irrigation is about 10CM), and the paint particles spread seriously too far. Within the distance of 20cm, most of the solvent volatilizes before it reaches the surface of the parts, and the particles of matte paint are special, which makes the paint particles advance. Of course, there is no adhesion, and they will be wiped off. It is suggested that the distance of LZ spraying should be kept around 10CM, and the small part can be closer.

2, dilution ratio (this is in the case of using a pen), matte paint don't spray thick, extinction will make the color below white, (usually not obvious) I tried, spray more layers of parts obviously white. LZ, add more solvent and spray it thin.

3. Pay attention to the humidity when using matte paint: when matte meets water (referring to the moisture in the air), it will turn white. It doesn't matter if it's sunny. Don't spray in rainy or humid weather, it will turn white seriously. It's really white You can spray a thin layer of solvent when the weather improves.

By the way, briefly list the influence of humidity on various paints (from heavy to light): extinction-metal-ordinary paint.

4. The difference between extinction effect and extinction effect can still be seen. Finally, the lack of particles means that these particles have no adhesion and naturally fall off; Extinction won't have any effect. The adhesion process of paint is accompanied by solvent, and the spraying distance is too long, which leads to the premature evaporation of solvent in the air. LZ can judge whether the paint is attached to the surface of the part normally: in the correct spraying process, even matte paint will produce a mirror-like effect through the refraction of light within 3~7 seconds (indicating that the solvent has been attached to the surface of the part). Spray painting, to put it bluntly, is the process from fog to liquid and finally to solid.
