Professionals involved in painting cars claim that it is impossible to paint a car in a garage in a quality manner. The body needs to be processed in specially equipped chambers under certain conditions. But the price of such high-quality painting will be quite high. And it is relevant for fresh and expensive cars. Usually, owners of older cars decide that car painting can also be done in the garage, with their own hands. How to do this, we will consider further.

Preparing the garage

The main rule of painting a car with your own hands in the garage is cleanliness. Dirt, dust, insects - all this is very dangerous for a freshly painted surface. Before work, the walls, ceiling and all elements are blown from dust, the floors are thoroughly washed. Concrete floors are covered with water two hours before the staining process.

Preparation

To get a quality result, you should start not with the purchase of paint and the necessary tools, but with preparatory measures. The result will bespectacular if the car is disassembled. Before the process, it is better to dismantle everything that is being removed from the machine.

Then, very carefully, all surfaces that need to be painted are washed with water and dried. To make this process go as quickly as possible, use a building hair dryer. Experts do not recommend drying the car in the sun - even a small wind will inflate dust on the body. An ordinary car dryer will not work due to its low power.

Protecting Items

Before painting a car, removable parts are dismantled from it, but there are also those elements that cannot be removed. These non-removable parts need to be protected somehow. A special paste or masking tape can help with this. You can buy pasta or make your own. For its preparation, chalk is mixed with glycerin and dextrin. Then add a little water and stir thoroughly.

This paste is used with a brush to cover parts that will not be painted. Work continues until the product is completely dry. While this mass dries, you should find rust on the body and remove it. Places of corrosion are carefully ground to metal, and then coated with a primer.

Removing paintwork

Some motorists prefer to remove old paint with a metal brush or sandpaper. However, these improvised means turn this process into painful and lengthy work. It is much more efficient to use homemade solvent.

In order to prepare this potion, we need pureedcandle on the grater. Then the mass is mixed with xylene. Then all this is heated in a water bath. After the transparent mass has cooled, acetone is added to it.

Then the resulting product is applied to the body - you need to spread it with a thick layer. Next, you need to wait a bit. After about half an hour, all that remains is to remove the old paint with a spatula and wipe the car thoroughly. If the paint is partially removed from the body, then it is removed mechanically.

A body without a protective coating will not be able to stand for a long time - it will begin to rust. Do not leave a car prepared for painting on the street for a long time.

Degreasing, puttying

All surfaces to be painted must be thoroughly degreased. It is best to use white spirit and lint-free cloths for this. The rag is rubbed with the product, and then grease and dirt are removed.

If there are mechanical defects, dents, various scratches on the body, putty is used to eliminate them. It is applied in a thin layer to the defect. It is better to use semi-liquid formulations and apply with a spray gun. When the putty dries, the area is cleaned with fine sandpaper.

Painting

Great if you have a spray gun for painting cars. If not, then you can use a vacuum cleaner. It is necessary to remove the filter, and a hose with a gun is connected to the outlet. The result is an atomizer. The paint is diluted and poured into a special container in a vacuum cleaner. In order not to stain the entire garage with paint, a film is placed under the workpieces.

First of all, the first developing layer is applied. Then, after it dries, irregularities will be clearly visible. They should be eliminated. Then the remaining layers are applied. When the last one is applied, the car is left for some time to dry. Then it remains only to apply varnish and polish.

About spray painting

Painting a car from a spray can is a favorite pastime of dealers. Many professionals are against this approach, but if the defect is small, then there is no better way than a spray can. The main thing is to choose the right color. There are also craftsmen who spray-painted their cars completely in garages. The quality turned out to be quite tolerable.

Technology has both disadvantages and advantages. Among the latter is the maximum simplicity of the procedure, which does not require additional tools and materials. If you paint with skill, you can get a good uniform layer of paint. The disadvantages include the lack of instructions included with the balloon. It is not on his body either. Paint for painting cars in cylinders is not always of high quality, and there are certain difficulties with the selection.

Preparatory work is the same as when using a full-fledged spray gun. It is better to spray paint from 30 centimeters. It is advisable to check the color and how the can sprays on a test surface that is not a pity. When working with spray paints, it is necessary that the room temperaturewas at least 20 degrees.

The paint is applied in several layers. First, apply the base, then, after 15-20 minutes - the next. The boundaries of the applied layers should expand. The drying time of the last layer should be at least one hour. Next, the surface is covered in several layers of transparent varnish. The technology is similar.

Liquid rubber

This compound is applied in order to protect the paintwork of the car. This material is able to protect the paintwork from various mechanical and chemical influences. Due to the wide range of colors and shades, you can adjust the color. The process of preparing for painting is similar to that already described above. Therefore, many choose liquid rubber for themselves. Reviews about painting a car in this way, by the way, are pretty good. I just need to add that some car owners recommend using isopropyl alcohol for degreasing.

Next prepare the composition. To paint a car with liquid rubber, the paint is mixed with a drill. This way you can better control the quality of the mixing of the components. With proper mixing, there will be no sediment at the bottom of the container. It is important to remember that the pigment contained in the composition quickly settles to the bottom. Before filling the spray gun, you need to mix the paint well with a stick in the container. After that, you can paint.

The car is painted strictly with a spray gun. If it is not there, then you can use a pistol with a nozzle of 1.8 millimeters. It's worth saving the paint. The air must be supplied in such a way that, from a distance of 30 centimeters, verysmall drops. This effect can be achieved if the pressure is 1 atm, and the torch has an average scattering angle.

To get a high-quality result, apply at least 5 layers. Each has a transparency of 50%. This technology provides a smooth color change. As for the color, it is better to choose the native color of the car. You can, of course, choose another one - the desired result is determined only by the number of these layers.

It is better to start painting from the roof. Layers should be thin and even. Each one takes about 20 minutes to dry. It will take about two hours to apply six layers. Without skills, it will take a little longer.

It must be taken into account that the last element needs at least an hour to dry. Then the car is left for a day for the paint to dry completely.

Raptor

Recently, car painting with the Raptor has become popular. This is a modern protective coating similar to liquid rubber. The coloring process is very similar to working with liquid rubber, and the result looks very impressive. Even non-professionals will be able to paint the car with the Raptor. The technology is no different from the above. As we have already seen, it is possible and necessary to paint cars in the garage if there is a goal to save money.
