Painting discs with powder paint: testimonials. Powder painting of discs with your own hands

A popular service in the automotive environment was the restoration of the appearance of the wheels. Painting cast discs with powder paint is in great demand and is the best way to return the car to its former form.

A reliable and modern method of surface restoration

The restoration of the physical state of cast discs involves a number of SRTs. Videos and advertising are found at almost every step. Difficulties can arise with the final part of the process, as well as with bringing the disc to its original form.

Powder painting discs today has almost no competition. This modern technology is successfully combined with a moderate cost and excellent result.

Myths about the complexity of the process

For many, disc painting technology seems complicated and conjures up a picture of a documented process with exact volumes of materials, people wearing special clothes, applying modern equipment.

But in fact, everything is not as scary and difficult as it may seem at first glance. But the problem is that the powder coating of the discs is impossible in the garage. The technology requires a whole complex, the price of which is quite high.

Advantages of dyeing powders

The process is very simple and economical, of course, if you use professional equipment. Only a small amount of material is sufficient for coloring.

Powder paint is distinguished by its great durability and good resistance to mechanical damage. These coatings retain their shade and texture for a long time. Also among the advantages are a wide range of colors.

Features

In numerous car service centers, powder painting of cast discs is performed using special equipment. Professional technology implies the presence of a special pistol with electrostatic effect. Using it, the dye is applied to the metal surface of the disc.

Then the processed products are sent to a chamber with a high temperature for baking. In this case, the composition is polymerized, and the paint becomes uniform. Before applying powder to the disc surface, the disc is thoroughly cleaned and then ground.

After polymerization, the layer is varnished to increase the strength and surface resistance, as well as to fix the result. When the procedure is performed at home, this method is not used, although the work stages remain the same.

Features of self-painting

The fact that the staining procedure in the garage and in the SRT is different does not mean that the end result will be worse. Powder painting discs with their own hands - this is not only an opportunity to save money, but also a way to improve skills.

Despite the advantages of using powder dyes, it is recommended to use acrylic analogs for independent work. But the algorithm does not change. Only other tools will be needed. However, motorists agree that the process of painting discs with powder does not justify itself, if you do work in the garage.

Paints: types, brands, colors

For work with wheel disks, the following materials are used:

• Epoxy - have increased resistance to alkalis and acids;
• Polyester - withstand the effects of the atmosphere and have a high resistance to corrosion;
• Polyurethane - withstand abrasion, oils and solvents;
• Silicone - persistently withstand high temperatures.

The modern market offers products from different manufacturers. Among them are Pulverit, P-EP-45, Bishon, RADAR and other compounds. All products allow you to very accurately pick up the necessary colors, choose the texture, type of structure. It can be moire, antique, shagreen. The most common range of colors is prescribed in the standard RAL. However, the market offers other options.

Preparatory work

Some consider this preparatory stage not so important and neglect it. This is in vain. If you do not give enough strength, time and attention to grouting seams, removing old paintwork, flushing dirt and oil stains, it will be difficult to get a high-quality result, which gives powder painting of discs. Preparation involves several important steps. This treatment with abrasive tools and chemicals, etching, phosphating, drying and washing.

In the process of abrasive and chemical preparation, there will not be any work that can not be done independently. At this stage, scale, rust, old paint is removed. Also, if necessary, the surface of the disk is leveled. For this, you can use both a different hand tool and a sandblaster. In the process of chemical cleaning, alkali or acid can be used.

By etching from the surface, remove those contaminants that did not disappear after the first stage of work. These are oxides and rust. They are easily cleaned with solutions of strong acids. This work requires special care.

The phosphating process involves the treatment of iron, chromium or manganese. Chromic anhydride is also used. With the help of phosphating, the adhesion of the paint to the surface increases. After all the preparatory steps, it is necessary to thoroughly wash and dry the product. After that, the disk is ready for painting.

Primer

It is not necessary, but still desirable. Priming compounds will help the disc to acquire resistance to corrosion, and also increase adhesion. Often used for primers are epoxy materials.

How to apply

The technology requires equipment. This is not done in the garage. The process itself is performed in a special chamber using a special atomizer. It acts by electrostatic principle. So, the charged particles of a powder under the influence of compressed air get on a surface which has a neutral charge. The powder is retained on the surface due to electrostatic attraction. Then the disk with the put powder goes to the chamber for baking and polymerization.

With your hands, you can only apply aerosol paint to the disc from the can, for everything else you need equipment. And it is quite expensive, and it does not make any sense to buy it once or twice. How much is the powder coating of the discs? The price of 3-5 thousand rubles is more than affordable, and the result is high-quality and durable. When buying the whole complex of equipment for this process, painting will be much more expensive than in the workshop.

Polymerization

This process takes place in an electronically controlled furnace. This is the only thing that distinguishes these devices from conventional dryers. The temperature regime for the melting of the paint is from 190 to 220 degrees. Electronics clearly monitors temperature conditions and time. After that, the disk is cooled.

Powder coating of discs: reviews

Car owners have already appreciated this staining technology. The result exceeds all expectations. According to car owners, the surface has a high resistance to damage, differs in bright color, can be matte or glossy. It is the high resistance to wear making this technology so popular. What many do not like is the impossibility of repeating the process in the garage.

If the discs have lost their aesthetic appearance, the powder coating of the discs will help restore their previous state. Feedback from those who have already used the service is a direct confirmation of this. Comments of people who applied to SRT, only positive.
