Consult the home with a colored panel spray white paint process

Your master's current practice is a more common and common practice.

Economical and practical. Save labor and materials.

But unscientific so leads to the current ills and results.

The scientific approach is to scrape the oily putty twice.

Spray white primer 2-3 times after sanding and smoothing.

Burnish. Spray white noodles 2-3 times.

The effect and quality of this is the most reliable.

The cost of materials is also not high.

It is that the construction operation is more troublesome and labor-intensive.

The reason is simple.

One. Now the scraped ash and the plaster that others say are water-based.

The construction is to increase the moisture content of the plate.

Swelling inevitably leads to cracking.

Two. These materials themselves do not have high adhesion and are not suitable for use on wood-based materials.

So it's easy to fall off.

In particular, it cannot withstand long-term hot and cold.

Wet and dry climate change.

Putty is economical and practical, and it is the kind used to make car paint.

THE TWO-COMPONENT IS ABOUT 10 YUAN.

It's just that it dries faster.

It has to be adjusted a little bit and used a little.

Slow work. Hope my advice is helpful to you ...

Fill in the defects first, then sand the object lightly, then do a good job of hygiene, and then apply two to three times of polyester transparent bottom or white primer, preferably white bottom, each time to sand, and finally two to three times of polyester white topcoat.

Precautions when painting.

1. The requirements for protection and closure work are particularly high. There are two aspects here, one is that the environment should be as dust-free as possible; Second, it is necessary to protect the paint film after spraying and do not damage the paint film.

2. All high-grade varnishes are used, and special color essence is used for color mixing, and organic pigments must be used for color essence, and inorganic pigments cannot be used.

3. Use different color ratios, spray 5-8 samples, choose the model with satisfactory tones, and then prepare the paint according to the fixed ratio, not too much each time, and finally start spraying.

4. During the spraying process, the change and contrast of the color difference on the paint surface should be observed at any time, and the color difference should be adjusted by using the residence time of the spray gun or the number of spraying times to make the paint tone on the surface consistent.

5. Every 1-2 sprays of paint, it is required to polish once, and water sandpaper must be used when grinding, gradually increasing from No. 300 to No. 1000, and a small amount of water should be dipped in water when polishing. The surface should be cleaned after sanding.

6. Generally, it needs to be sprayed 5-8 times, and the last 1-2 times of topcoat can not be added, so that the decorative effect of the paint surface can have a sense of hierarchy and three-dimensionality.

It is better to apply it first with paint remover, and then.
