In the interior design is becoming more and more fashionable airbrushing. To paint the walls of your own home, you don't have to be an artist or a professional. To do this, it is enough to be patient and know how to use an airbrush.
Airbrush in section.
Airbrush: which tool to choose?
It is very important to choose the right apparatus for painting. There are several varieties of airbrushes.
First of all, the choice of tool depends on the skills and professional level of the specialist in painting.
So, devices for the professional and the fan will differ. When choosing a device, it is necessary to carefully study its characteristics in order to choose one that will meet all your requirements. So, when choosing a pneumatic sprayer, you need to pay attention to the following characteristics:
The principle of the airbrush.
- The nozzle and its diameter. That nozzle is responsible for the flow of paint. Depending on the surface area to be painted, an airbrush is selected with one or another diameter of the nozzle. For example, to paint the background you need to choose an airbrush with a nozzle, whose diameter is 0.35 mm, and for drawing details a nozzle with 0.2 mm in diameter will be suitable. There are airbrushes with a set of nozzles of different diameters, which significantly saves finances, since it is difficult to manage with one nozzle. However, it is necessary to spend time re-installing the nozzle of the desired diameter.
- Tank, its location on the machine. From the tank depends on how the flow of paint. It can be located on the side, bottom or top. The tank may be completely absent. Then the flow of paint through the slot directly on the needle. An airbrush with a needle is indispensable in cases where complex painting is performed, where the drawing consists of fine details. If the drawing consists of a large number of different colors, an airbrush with a needle is also needed, since it allows changing the paint frequently.
Airbrushes for professional and amateur will be different. In this case, there are 2 types of devices:
According to the type of supply of paint material, an airbrush is divided into: from an airbrush with a lower supply of material, with an upper supply of material and with a supply of material under pressure.
- Single action. They will suit amateurs, since it is not difficult to paint with an airbrush of this type.
- Double action. They differ in that they can be controlled both through the needle and through the air supply. These devices are suitable for professionals. They allow you to perform more complex painting, the pictures are more realistic.
- Automatic airbrush. It is a kind of golden mean, especially for beginners. It differs in that the management of the needle is possible only after turning on the machine.
In addition to the apparatus itself, you will need a respirator, a hose, an air filter, a stand.Back to table of contents
Elements of the airbrush
Before you start working with an airbrush, you need to be clear about what elements (nodes) it consists of and what each of them is responsible for:
In order to do airborne paint under pressure you need a suitable compressor.
- Nozzle. It regulates the diameter of the jet of paint that is applied to the spray. Located at the end of the spray gun.
- Tank. In this capacity there are paints with which the master is currently working. The most convenient are those models of airbrushes, in which the tank is located on top.
- Needle. It regulates the flow of paint from the tank. If it is necessary to paint a large area, it is better to choose an airbrush with an external spray, it does not have a needle.
- Lever arm. It regulates the flow of color and air.
- Adjusting screw It provides independent adjustment of air pressure to the total pressure in the compressor.
- Air valve. Thanks to him, the air passes through the nozzle.
- A pen. In fact, not all devices are equipped with this part, but it definitely makes working with an airbrush more convenient, otherwise you need to keep the machine by the body.
- Power parts. These include air hoses and a compressor fitted with a receiver. They compress the air and feed it to the unit.
Airbrush designs may vary, but the details that make up the devices remain, as a rule, unchanged.Back to table of contents
Airbrush: preparing the device to work
The technology of applying paint with an airbrush is that you need to do everything in stages:
In working with an airbrush, a stencil is usually made of cardboard, thick paper, film or special foil.
- Surface preparation. In particular, it is necessary to eliminate any defects (chips, cracks, etc.).
- Treat the surface with putty, plaster, primer. The latter must be chosen on the basis of the type of paint chosen for coloring.
- Surface degreasing. It should be dry and clean.
- Even out the tone if the surface has a grayish tint. Usually, for this, the surface should be painted with white paint or the lightest color, which is present in the future drawing. 1 or 2 layers is enough.
All these stages concern only the preparation of the surface, which will later be signed. Before starting work, it is important to either take the furniture out of the room or cover it with a film.Back to table of contents
Tricks that are not written in the airbrush instruction manual
The technical side of the issue, that is, how the airbrush is activated and worked with it directly, is described in detail in the operating instructions of the specific apparatus. In general, it looks like this:
- the hose of the machine must be connected to the compressor;
- compressor on;
- blow air through the nozzle (this should be done aside).
The main characteristic of an airbrush is the diameter of its needles and nozzles, which determine the potential of the tool.
Before using each new color in the process of painting it is necessary to blow a nozzle. To do this, fill the tank with solvent. This is important to avoid mixing paints. In addition, it will be better to check the purity of the color before applying the paint to the surface. To do this, spray the paint onto the mixing palette, which can even serve as a thick sheet of paper. This will prevent unwanted mixing of shades, getting a “dirty” color and will provide a neat and beautiful result.
The paint in the airbrush tank is filled with a medium-sized brush or pipette (pharmacy or designed specifically for airbrush).
Tricks to help avoid mistakes and achieve excellent results:
- Dynamism. It is important not to hold the device in one place for a long time, otherwise there will be a leak.
- Contactless. Do not in any way contact the apparatus with the painted surface.
- The angle of the machine. The optimum angle due to which errors in operation can be avoided is 90 ° relative to the surface to be painted.
- The optimal number of layers of paint. It directly depends on the complexity of the picture and on how voluminous it should be in the end. For a volume effect, you need from 5-6 layers. In this case, the overlay method is often used when the layers intersect.
- Drawing techniques. Of course, aerobatics is the painting that artists perform. However, there are more simple ways to apply the picture. For example, screen graphics. The stencil can be made in any graphic editor (for example, Picasa), in which the image is decomposed into layers. Then each layer is separately printed on the printer. You need at least 4 components: the contour, the main color basis, shadow and partial shade.
- The distance between the device and the surface. The smaller the part or the thinner the line, the closer the airbrush should be to the surface. If you can not draw a line with the machine, it is better to use a regular brush.
- Drying. After applying to the surface each layer must be thoroughly dried.
- Varnishing. The whole picture varnish is not worth it. It suffices only in some places to work the surface with a brush in order to obtain additional optical effects. It is advisable to do this in bright or very dark colors.
Briefly, the mechanism of action of an airbrush can be described as follows: air is blown into the apparatus under pressure, which creates an air jet; it gets a dye, as a result, sprayed. This allows you to create original drawings on almost any surface.Back to table of contents
Paints for painting: varieties
The choice of paint is another important stage at the stage of preparing the surface for painting. There are several types of paints that are used in airbrushing:
- Oily. Their advantage is ease of use. They are ideal when painting roofs or walls. The downside to oil paints is that they dry for a long time.
- Acrylic. The undoubted advantage of these paints is their moisture resistance. This makes them an ideal option, because they are not afraid of wet cleaning.
- Latex. The peculiarities of these paints are their resistance to moisture and the possibility of applying them directly to the wallpaper. This is ideal for painting on the walls.
- Water emulsion The undeniable advantage of this type of paints is their non-toxicity and safety for the body of people and pets. In addition, this paint has no peculiar smell. This is an ideal option for coloring the kitchen and bathroom. However, water-based paints have one drawback: before applying them to the surface, you must first apply a glossy paint.
A lover is enough to buy the optimal set of colors: yellow, red, black, blue, white - they will be quite enough. However, more complex shades will have to be achieved by mixing these basic colors.
