The sprayed paint is dry, like dust

Nippon Paint wood paint powder is heavier, spray the plane when the temperature is high in summer, if the furniture such as the wine cabinet or bookcase, the corners will not be smooth, it is recommended that you use a special thinner in summer, do not spray when the temperature is high, do not hit the valve too much, do not add too much thinner, and, spray the bottom of the cabinet first, then spray both sides, and finally spray the top, in short, you are doing home decoration, slowly comprehend.

It is recommended to close the paint tightly, otherwise the dust in the air will be adsorbed on the surface of the paint, and the harmful gases in the paint are not easy to volatilize.

Also, before spraying paint, be sure to clean the base layer, otherwise, it will not only affect the color, but also affect the adhesion, and it is easy to peel off the paint.

If it is not for the above two reasons, it is recommended to check the paint, whether it has been placed for too long, or it may be too much moisture in the air, which will also affect the color of the paint.

The principle is that the paint thinner volatilizes too quickly, the viscosity becomes larger, and the spray gun spray paint is more accelerated volatilization, so the paint will dry and form particles. Solution, when the temperature is high, change to a thinner that evaporates slowly, and increase the spray volume in the appropriate range.

The main thing is the proportion, and the thinner is not used in summer, I have been doing Nippon paint for a few years, and every year I have done oily paint, and there has been no such problem, but I use a paintless sprayer, and there is no dust on the wall, if there is, then spray it out, just like you said.

I guess the paint is expired.

Hello, there are three reasons why the paint is sprayed and spreads out like oil: first: the paint itself is a problem.

Solution: Try to replace another paint Second: the problem of the construction crew, mainly the paint is too thick; Improper paint mix or mixed use of different brands of paint, leaving it for too long.

Solution: Try to add thinner appropriately, try to use the same stool to stack the paint and then replace the paint: solid:

Diluted proportions. Third: the surface of the furniture being constructed is not well treated.

Solution: Re-sanding the jujube mold solution with sandpaper.

First: the problem of the paint itself. Solution: Try changing to another type of paint.

Second: the problem of construction personnel, mainly the paint is too thick; Improper paint mix or mixed use of different brands of paint, leaving it for too long. Solution:

Try to add thinner appropriately, try using the same paint and then change the paint:solid:thin ratio.

Third: the surface of the furniture being constructed is not well treated. Solution: Re-sand with sandpaper.

The face oil is loose and oily, whether it is a problem of wiping color.

After spraying the topcoat, there is a lot of dust on the surface, and there are a lot of things on the surface of the paint.

The cause is that the spraying workshop is not clean, for example, there is no filter cotton on the surface of the paint room, and the filter cotton on the roof has not been replaced for a long time. The compressed air is not clear, the key is not clean, the painting operator does not wear special work clothes, and the spraying surface is not clean. The paint is not effectively filtered before spraying.

2) Correction method Keep the paint workshop clean, regularly replace the filter cotton in the paint room, and strictly prohibit grinding putty in the paint room. Ensure that the compressed air is clean and change the filter regularly. The sprayed surface should be cleaned with compressed air or a dust cloth before spraying.

Properly seal and store the paint, and the paint should be fully stirred before spraying, and filtered before use. If there are already dust spots, they should be sanded to a smooth surface before recoating. For slight dust spots, fine sandpaper should be used for sanding and polishing.

What kind of lacquer? One is that the paint quality is not good, and the other is that it is not used correctly. For alkyd paints, in addition to poor quality, it is possible that it is not dry if it is too thick, the temperature is too low, and the humidity is too high.

The situation is similar for acrylics. For two-component paints, it may be that the mixing ratio is not right. And look at the bottom of the treatment?

Oils, waxes, etc., or thinners that are not matched can also cause the above problems. It is recommended to warm (sun) to see if it can be solved.

Just continue to polish, polishing can remove dust;

1. Polishing is a method to test the quality of painting, and after polishing, you can identify whether the thickness of the painting is uniform, which can expose the problem of cutting corners in the painting process.

2. Polishing can remove tiny dust and pores during the painting process, making the paint surface brighter.

3. It is important to wait for 3-5 days for the paint surface to completely dry before polishing, otherwise it will backfire.
