How to prepare the machine for painting: step by step instruction

On how well the master knows how tomachine to prepare for painting, the final result depends. The paintwork will last a long time if everything is done correctly. However, if the rules are not observed, all work can go wrong. How to prepare the machine for this operation, so you do not have to redo it? We will talk about this in our today's article.

Many car owners believe that the processtraining is not so important, but only a small oversight, to finally and hopelessly spoil the result. Painting the car on its own or in a specialized workshop takes only 10% of the time - everything else is spent on preparatory work. All its stages can be performed in 1-2 days in garage conditions. The main thing is that everything should be done strictly according to technology.

Preparation of the working area

Before the preparation of theit is important to properly prepare the room, where the machine will then be painted. The main requirement - it must be dry, warm. And of course, there should be no dust inside the room. It is worth remembering that any paint is highly flammable. This is why there should not be any sources in the room where the car is to be painted on its own, which can lead to a fire.

Required Tools and Equipment

To prepare the car for painting,you need a certain set of equipment. It's a grinder or a Bulgarian. Also in the process will be used pneumatic pistols - with their help on the body will be applied liquid putty and primer.

To thoroughly and completely dry the body afterprocessing, it is recommended to use infrared emitters - this equipment will not only allow the machine to dry out evenly, but it will also significantly speed up the process.

Preparation of the car for painting necessarily requiresapplication of putty, and therefore, you need to buy all the necessary putty and primer compositions. It is not superfluous to have a paint tape, abrasive wheels for a grinder. Many recommend using masking tape, film and clay. And, of course, you need a set of tools - putty knives, planes, paint knives and bars.

Cleaning the surface of the body

Any details that may interfere with the processstaining (and these are different moldings and other decorative details, locks, any seals) must be dismantled. If this is not done, a large amount of moisture will accumulate under these elements during the washing process, resulting in corrosion and the machine will rot immediately after painting.

Many people neglect this and consider thisaction optional. But experts who know how to properly prepare a car for painting, it is recommended to do it this way - to make a complete dismantling of all unnecessary elements.

Before driving the car into the working area, itsshould be thoroughly cleaned and wiped with a cloth. Use a rag that does not leave a pile. The dirt itself will be removed only under the influence of a strong and powerful jet.

How to inspect a car

Experts willingly share with beginners secrets,how to prepare the car for painting yourself. If you follow all the rules exactly, you can get a good result. At the next stage of work, the car must be carefully inspected.

The body is carefully inspected. In the course of this process, it is necessary to decide which parts will subsequently be repainted. Also during the inspection, the owner will understand which elements should be leveled with putty. Next, you decide which painting will be performed - partial or full.

Paint selection

Choose the right paint for the entire bodysimply, but in the case of partial coloring, everything is much more complicated. If the repainted part is even slightly different, then it looks very rough. Therefore, many SRTs have computer systems that allow you to choose the right color.

At home using a single computerthe color issue can not be solved, and therefore it is necessary to follow a different scheme. How to prepare the car for painting and choose the right color? To do this, you need to know exactly the color number printed on the body at the moment (under the hood is a metal plate with a shade code). What else you need to know about how to properly prepare the machine for painting? Of course, the required number of materials.

To fully paint the body of a 4-doorsedan, you need 4 kg of primer and 6 kg of enamel. If a partial tint is applied, then for each square meter, 110 grams of enamel and 150 grams of primer are required.

And most importantly, what beginners should knowmotorists on how to prepare a car for painting - both enamels and primers should be the same manufacturer. Otherwise, there is a risk of tearing off the coatings.

How to protect unvarnished body parts

All the elements that are not planned to be painted,carefully closed. For these purposes, professionals recommend using special stencils. They are attached to the right areas for paint tape. For places where there are even lines, you can use a medical plaster - this is the ideal solution. But often in questions, how to prepare the machine for painting with your own hands, practice other options - a special compound is used.

Mix 20% dextrin, 30% glycerol, add40% chalk and 10% water. After the painting procedure, this mixture is very easily washed off with ordinary water. The most important thing is that this drug does not get on the stained areas.

Degreasing and grinding

The best tool for this operation isWhite Spirit. After the body treatment, all surfaces to be painted should be dry. The next step in this task, how to prepare the machine for painting, is called abrasion. This is the most difficult process. There are several methods of grinding before painting. The most common are mechanical and thermal.

Features of grinding

The mechanical method is an ordinary grinding using sandpaper with a grain size of 100. Also, a special grain 240 tool is used for the final result.

What is the most important in this process? Compliance with the rules of gradation of the denominations of abrasive. The rule states that the value of the grain level between the initial and the next paper must be at least 100. Otherwise, there is a risk of precipitation of the paint.

Thermal cleaning

A blowtorch is used for this treatment option. Sites that are repainted - burned.

Paintwork as a result of heatingwill soften, and it is very easy to remove it with a brush. However, this method has a drawback - if the heating is not uniform, then there is a risk to significantly disrupt the integrity of metal and decorative elements. But so you can very quickly prepare the machine for painting.

Other ways of cleaning the body

Specialists also distinguish other methods of purification- is the use of sandblasting technology and the use of chemicals. Sandblasting is often used to remove corrosion - cleaning is carried out as quickly and efficiently as possible. The method of chemical cleaning will suit, more likely, for removal of a varnish on all surfaces of a body at its ideal condition. Solvents will perfectly cope with any paintwork.

After cleaning

After grinding or any other treatment, another degreasing is performed. Then the body is again wiped off with lint-free fabrics. After that you can proceed to the next stage.

Putty

The application technology depends on the vehicle andthe task. Sometimes the structure is additionally added with fiberglass or aluminum powder. The number of layers is determined by the task. Apply putty on the surface strictly across the dents, while aligning it.

Once the putty has lumps, it's best to stop work. If the mass begins to dry out, there is no point in touching it. Dry putty on average for 15-20 minutes.

Padding

At the final stage, the soil is applied to the body. These compounds will significantly improve the quality of adhesion of the paint and painted parts. In addition, the primer compositions protect the metal from corrosion.

Primer is performed in three stages. On the first, phosphating is carried out. Then, with the aid of leveling primers, small defects are removed. At the last stage, the soil gives the surface an ideal appearance.

Experts who know how to prepare a car forit is advised to apply the first coat of primer with a horizontal line. In this case, each of them must overlap the previous one by 50%. The second is applied vertically and with a thinner layer. Each of them must dry out within 10 minutes. Do not apply more than three layers. Further, the surface should dry for 2-3 hours. Then it is polished and degreased.

So, we figured out how to prepare the car for painting with our own hands in garage conditions.
