How to paint the car
Car Painting in the workshop is expensive, many motorists prefer to paint in the home and with his own hands. Therefore, we consider the painting process, the cost and nuances.
Any defect on a car body always pulls the painting . But unfortunately not everyone manages to do it, because not respected technique and sequence of actions when painting cars. And even this is not enough to be, if you do not carry out this process using special equipment. Especially, the motorist must have special skills in this matter.
Preparatory work and inspection body
Corrosion and chipped on the body
Before painting, it is recommended as carefully as possible to wash the car. It is this detail will consider the entire surface for defects. The first and main defect is the vehicle corrosion. But this list does not end there, and swell the ranks of his grain of sand, stones and all sorts of small abrasives. And it’s all because of these “minor pests” hurt the car body and its bottom. The result is that there are various kinds of scratches and dents, which must be removed before painting.
It is recommended to carry out preparatory work before taking up car paint. Car Coloring usually is of three kinds: partial, spot, or capital. It depends on the damage to the vehicle surface.
Usually, car painting takes an average of 10% of the total time of the process, but the remaining 90% takes preparation. For a start it is recommended to remove all locks, seals, moldings, and everything that can interfere with high-quality paint. But when it is ignored, and the elements and remain fixed on the car or else they simply sealed with masking tape, then the accumulated moisture that fell through the cracks of these parts in the future adversely affect the car paint.
Rust under paint
After removing unnecessary elements of the car body surface is trimmed, puttied and apply a prime coating. Next, the surface of the old coating is removed, and the place of distribution of corrosion are processed.
By the way, when the vehicle paint is necessary to use the products of one manufacturer, since materials from different manufacturers are usually rejected. It is because of the painted surface will not last long.
Body cleaning before painting
In the process of “fighting” with road dirt and dust in car washes are ideal autoshampoos and, of course, water. Such spots as bitumen or fat is recommended to remove special tools or using White spirit otherwise they spoil the painting process. All tools are available in every auto shop. But in such situations may not use gasoline or any other solvents as when painting, it will manifest itself immediately.
In case of full polkraski car body is necessary to dismantle the front and rear bumper, remove the decorative grille, headlamps with front and the radio antenna, external lighting equipment, direction indicators and other details that may hinder paint or leave a trail of mud after the application of paint. After removal of all parts should be thoroughly washed the body. If the wheel arches is present or impact protection from dirt, then it must also be removed.
Scraping and leveling surface defects of body
In order to best examine the defects of varying degrees it is recommended or else put the car on a well-illuminated place in the garage, or else go to an open area on a sunny day for a better perception of the condition of the body. Suffice visible defects, such as, for example, dents or cracks are marked, usually with acrylic paint or colored chalk. After the first inspection, it is desirable to again look at everything in order to avoid undetected defects, which may eventually become a hotbed of corrosion and stop painting details.
The next step is trimming defective places. To do this you need a chisel or a sharpened screwdriver (width of the tip of which should be 3-5 mm), and the sandpaper with the numbers 60, 80, 100. It should be noted that surface dressing area should be as good as possible approximate to the area, “the affected places” . This will avoid future additional costs of material and time when further adjustments painting.
It is also important that the transition should be smooth from a defective non-defective surface of the car body. For a sense of “evenness” enough to run your hand along the surface of the body, there should be no gaps or waves on the surface.
Removal of small defects in the body
This is followed again and attentively as possible to wipe the surface of the body from dust. To the stripped sites is desirable to use a cotton cloth and dampen her pre-White-spirit. After that, the body must dry. But when the car made major repairs, then necessarily need to wipe the entire surface of a cloth body differently during the painting emerge all the dirty places.
The next point in the car’s paint is putty defects. For this need: rubber and metal spatulas and polyester synthetic automotive putty. Do not forget the finishing putty, as it helps to plug the problem areas. It’s all because of its characteristics, as it is fine-grained, and therefore, for grinding work will be carried out “like clockwork.” Special steel blade will stir putty and hardener. Typically, this solution obtaining proportions indicated on the jar.
For stirring the mixture required 30-40 seconds. Immediately after mixing, the mixture must be applied on the problem areas. Thus it is necessary to create a cross-motion with a turn of 90 degrees. The result is a flat and smooth surface of the damaged area, which is not much to separate from the surface of the car body and is ideal for painting.
This means that within five minutes after it begins to generate heat stirring. It is therefore necessary to work quickly but accurately. The main thing is not to miss the time, because then begin to appear in the filler lumps. And this putty can not be applied to the surface.
Putty should be given time (which is about 30-45 minutes) to become solid. To check the surface ready for painting, you can simply wipe it zashpatlevannoe place sandpaper dry sandpaper (number 80). When the putty does not stick to the paper grains, it means that it has already dried up.
The skins number 120-600 will help in cleansing shpatlevannoy surface of the car, which is carried out by hand to painting. We clean the surface should be as long as equals on the geometry and roughness of the body. It is recommended to carry out this cleaning in several steps, and from time to time and if necessary lubricate putty. Also, you should avoid contact with the water putty, because then it loses its quality and coloring will not work.
Again, to control from time to time is to hold a hand on the treated surface to check for dryness. When the filler is dry and leveled all the geometry, it is necessary to clean the appropriate place for the painting from dust with a cloth. Tatters need to moisten White spirit and dry.
Next, before painting the surface of the body is applied to the primer layer with a light-brown tone and with “zahlestom” on a clean surface. Also do not forget about the quality control has a clean surface ready for painting.
Preparation for vehicle painting
This is followed by masking tape to stick precisely those places that will not give in color. The same applies to car wheels. Also note that the height of the indentation between the painted and unpainted body elements should be approximately 0.02 millimeters. Features of these elements is to place on the outskirts of the bend or on the edges of the necessary car parts on the body surface.
After the above is necessary to apply the sandpaper number 1200 zashkurki paint matt. Again, again, using rags and White spirit is good to wipe the treated surface and leave for a while to dry.
Garage for car paint
Now, however, it is worth mentioning the workroom, where the car will be painted. In most cases, car painting is done on a large enough garage, but then, to around the perimeter of the auto working area is not less than 2 meters. This situation must be considered to be clean garage. That is, that there was no dust and dirt from the ceiling to the room is not sprinkled with fine particles. Also, you must first wipe the floor with a wet cloth. Often the walls and ceiling pull the film, it protects from excessive dust.
At home, car painting conditions it is necessary to give preference to enamel drying ability, and not baking. But the choice of brand paints and enamels depends on the motorist and his financial capabilities.
Paint the car surface
The first step is to paint, need to dissolve the enamel with solvent to the desired consistency by following the instructions. Thereafter, the compound materials need a special mesh filter through a funnel. The mixture is then poured into the paint gun. It is noted that in such cases it is necessary to use a gun nozzle № 1,4 which air pressure of 2.5 – 3.0 bar.
It is best to start the vehicle painting process itself, with its roof, keeping the nozzle at a distance of 1.5 – 2.5 cm from the surface to be coated.. Movement should be smooth. After applying the first layer, you need to wait about 15 minutes until the enamel to dry and do not hold paint more 1-2 times with a time interval.
Three health protection rules when painting:
Car painting is done only in well-ventilated room and dressed in a respirator; in the room where the painting is done, in any case do not smoke; as far as possible is constantly ventilate the area after painting.
As with any paint color starts normally only occur after the second staining. A drying the entire surface of the car need 24-36 hours following the temperature conditions of + 20 ° C.
The choice for car paint painting cost will largely depend on how large the portion requires painting. On average, for every detail of the car professional painters take about $ 50, it refers to domestic cars and conventional cars. If we take the foreign cars with premium, the cost could rise to two or more times.
Count is the fact that they themselves paint and varnish materials for painting are not cheap. In addition, you will need to purchase sandpaper, and other tools for painting. The average price of a car paint starts at $ 10 per 1 liter. Nail coating of paint will cost from $ 5 per 1 liter.
