Common problems with automotive repair paint
Why are the orange lines on the surface of the varnish so heavy after each spray? Why on earth? How can we prevent a decrease?
Answer: The thinness of the varnish, the amount of paint produced by the spray gun, the size of the standard air pressure, and the spraying technique are often mentioned. It is often said that if the varnish is too thick, I will use a ratio of 2:1 for varnish 2. Epoxy curing agent 1, and add a little paint thinner after spraying one talent; The second option is that when you spray varnish, the gun is too thin and you have to press it down.
2. How can silver powder paint be sprayed to make the particles exceed the fine size?
Answer: It depends on whether the car paint itself is coarse silver or fine silver. If fine silver is used, even if the paint is sprayed in proportion, it will still be fine; Coarse silver needs to be sprayed thinly and thinly. Only when the base is well prepared, can it be ground with fine sandpaper before spraying thinly.
The selection of paint thinner should also be based on the external temperature. Slow drying paint thinner should be used on hot days, and quick drying thinner should be used on cold weather. It is necessary to follow the manufacturer's instructions for actual operation. The spray gun used is also very important. If the actual effect of atomization is not good, it will immediately endanger the actual effect. It is recommended to choose a brand spray gun.
3. How does the insertion of saliva appear inconspicuous?
Answer: Turn down the atomization and the standard air pressure to a smaller white point. The actual effect of the test gun is good, and the atomization is fine. When spraying the nozzle, wet it a bit, and then dry it to see how the actual effect is.
If it's not ideal yet, spray it multiple times again. If the water at the nozzle is too wet, it will cause tears. Car paint thinner is not easy, and if the nozzle needs to be polished, using paint thinner is stronger. There are also sockets that need to be sprayed with varnish, and a little more paint thinner needs to be used to make it very thin. Similar to what I mentioned earlier, it means that there is no need to blow after spraying.
4. How can white pearls be sprayed stronger?
Answer: The bottom layer needs to be treated well, sprayed with white base, which is very easy to bite. Then, sprayed with white base, sprayed with real pearls. Remember: the viscosity of real pearls needs to be adjusted accurately, and do not thicken them anymore.
At the beginning of spraying, it is usually only possible to float the pearl twice. After each spraying, unravel the newspaper and compare the color tone to see if it is close. If the color tone is good, it is slightly lighter than the original car and can only be sprayed with clear paint.
5. Shortly after, I sprayed a sedan, Ma Liu, and there were no problems with the first coat of varnish. The second coat of varnish was always a good idea. I used to use water before spraying, and I have been working as a painter for more than 5 years. In recent days, I have always had problems spraying one car after another, which has left me confused. It seems like I have returned to the time when I first started my apprenticeship and want to switch careers.
Answer: You can see if the water is good and the idea is making a small nest! There will be epoxy curing agents for varnish that have expired and will not change! Some also say that after mixing the varnish, it needs to be mixed for a while longer! Mix it and wait for 15 minutes before spraying!
