Airbrush for modeling is used to work with crafts and their components. Usually these are small details, the coloring of which should be carried out especially carefully, taking into account chiaroscuro and the creation of different shades. The model is pre-prepared, after which paint is applied in layers. A step-by-step description of the process and practical tips can be found in this article.

Before you start using an airbrush with a compressor for modeling, you need to prepare the object. The main procedures are:
- Matting, that is, applying an abrasive with a sandpaper. Fine particles remain on the surface and provide good adhesion to the paint.
- Degreasing - for this, a silicone-based cleaner is used, as well as a special thick napkin. After processing, it is no longer possible to touch with your hands, so as not to introduce other contaminants.
- Priming - apply 1 or more layers. This procedure should be started only when the entire surface of the part becomes matte.
How to paint a model
An airbrush for models is used in much the same way as for painting other objects:
- Place your hand at a distance of 15-20 cm from the surface to be painted.
- Make smooth strokes and press the trigger.
- Press the air valve and press the lever to release the paint.
You should not just press the trigger and drive with your hand, because in this case the paint will lie down with the formation of bumps and air bubbles. Therefore, it is better to apply the base coat without haste. And after it dries, apply a new layer.
During work, you need to immediately think about chiaroscuro, the distribution of shades. You need to immediately think about where the light comes from. If a shadow is planned somewhere, the tone should be darker.
Separate areas are painted in other tones. Therefore, they must first be covered with masking tape or vinyl.
Practical tips for using an airbrush
Airbrushing models is in many ways a creative process, but it also requires accuracy and knowledge of the characteristics of paints. To make the part look beautiful, it is recommended to consider a few tips:
- Use mostly acrylic paints. They do not burn films, do not pose a danger to children.
- Do not combine paints with different properties, such as particles of different sizes. It is highly not recommended to use compositions based on a mixture of enamel and acrylic paints.
- If a complex model is being painted, for example, a tank, you should consider it and think about how to get to each part with the device, as well as plan a sequence of actions. Small parts are best removed and painted separately, and then installed on the model.
- Since any composition gradually stagnates, immediately before work, the paint must be thoroughly mixed. If the consistency is too thick, add a little thinner.
- Before work, always carry out test staining on the surface of plastic or paper. If the device spits, the layer is uneven, resembles crumbled semolina, it is necessary to adjust the pressure, clean the nozzle, dilute or replace the paint.
The use of an airbrush for modeling has its own characteristics. The detail should turn out neat and beautiful, often with different shades. Therefore, it must be carefully prepared, and then gently apply the composition under optimal pressure. For this, test staining is done, after which they proceed to the main work.
