Recently, Russian car owners often complain about the “weak” paintwork of modern cars, not only domestic, but also foreign. Although at the moment they are much more concerned
– Maxim Mikhailovich, let’s, as they say, from the stove: what is the service life of a car paint?
– There are certain standards and even GOSTs. According to them, the paintwork should last three years in a humid climate and five years in a temperate climate. In this case, it is necessary to separate the concept of “paint” and “coating”. The coating is a whole layered cake. First comes the preparation of the metal, then phosphating, application of the primary primer, then cataphoresis, secondary primer, base and lacquer. And this “cake” must be on the car for at least five years.
– A well-painted car can rust without defects?
– Here’s the whole question of how the already mentioned “pie” was prepared. Have you applied all layers? All dried according to the rules? In the USSR, cars rust, because sometimes they did not even paint with primer – only paint. If the technologies are maintained correctly, the materials are of high quality, then rust should not appear, the paint will not peel off, oxygen will not enter it, oxidation will not occur, rust will not form.
– By the way, are the paints for a new car different from those for repairing a used one?
– And how! The repair material is different, in particular different drying temperatures are specified. On conveyor belts it reaches 130 and even 160 degrees Celsius, and in repair shops they can dry at 60 and even at 20. Another chemistry designed to work in more accessible, simple conditions. The conveyor belt is a specialized technique, robots, application without the slightest defect.
In the repair shop, everything is much simpler, and the process takes more time. The master can afford to dry the car for 10 hours, but the factory cannot. A new car rolls off the assembly line every 5 minutes. Repair materials require less attention, but they also last longer in the coating. Therefore, the story about “paint from the assembly line” is a story of the Soviet era. Now everything is different.
– Is it true that for an acceptable result you should take primer, paint and varnish from the same manufacturer?
Also a myth. Of course not. Paint is a certain chemical composition, which is more or less similar for all manufacturers. There may be some characteristics, of course, but in general the composition is the same. Therefore, he behaves in much the same way. Hence the stories that house paint is bad and imported is good. Put two cars next to each other and say which one is painted with what. Never tell. It is not the country of manufacture of the paint that decides, but the exact observance of all conditions and the implementation of operations.
– Paint for plastic, for metal, for wood, for leather – are they different? Or the same composition, but in different bottles?
– These are different colors. Different products with different properties and compositions. They can also differ in terms of durability and method of application.
– Pencils to update chips. Employment history?
– In everyday life – yes. Home and a file is a tool. It is a fairly common option to remove minor scratches and chips. Very comfortable. By the way, it is very popular.
Is it possible to paint a car from a spray can?
– Very physically demanding. Yes, and expensive! Paint in an aerosol can is much more expensive and applying it to large surfaces is extremely labour-intensive. The layer thickness cannot be maintained. Easier and cheaper – spray gun.
– What should you pay attention to when buying paint?
– Don’t chase cheap. The best quality will be with a professional product. But at the expense of a well-known manufacturer – the marketing component is greater. Listen to your master: what kind of paint he worked with – buy it. Many painters have been working with compositions from the same manufacturer for several decades, they are used to it, they know how to achieve the desired result. Here’s what to buy. And for yourself it is worth relying on a product that has been on the market for a long time. If the store has been selling paint for several years, then it is quite a decent manufacturer, you can handle it. Since they have been trading for so many years, the paint deserves trust.
– Why is it necessary to paint a gas mask?
– Paint is a chemical product that should not get on hands, eyes, nose and mouth. Such a hit is fraught with health consequences. Of course, you need to protect yourself, use basic security measures. Cases of poisoning with paint are very rare, but it can give you a “head”. As however and when interacting with any other chemistry. So a respirator is a basic piece of protective equipment, it should be used especially when working in confined spaces.
