In large rooms and rooms with high ceilings, the use of paint brushes and rollers is not practical - these tools make the process more time-consuming and lengthy. In this case, the best solution would be a spray gun for water-based paint - it greatly simplifies the painting of walls and ceilings and allows you to create a high-quality surface with your own hands. In order for the repair work to bring the desired result, it is very important to choose the right spray gun and learn the basic rules for its operation.
to contents ↑Advantages of using a spray gun
- Significant reduction in painting time. The spray gun increases productivity and reduces the time spent by almost half.
- Applying a uniform and thin layer of paint reduces the consumption of material and provides quick drying of the ceiling and walls.
- Lack of stains and streaks - the dispersion is distributed on the surface in an even layer, and unlike brushes and rollers leaves no traces.
- Ease of use and simplicity of the mechanism, thanks to which you can easily perform high-quality decoration of the premises with your own hands.
Manufacturers of spray guns strive to provide maximum ease of painting, so they supply a set of interchangeable nozzles. Nozzles or nozzles have different diameters from 0.5 to 3 mm, which greatly expands the possibilities of using the tool. The nozzle can be selected depending on the required spraying intensity, the smaller the nozzle diameter, the lower the air pressure, therefore, to work with viscous paints larger nozzles are recommended.

How to choose a spray gun
The modern market offers a huge range of spray guns, so everyone can choose the best option for painting walls and ceilings with their own hands. With such a variety, it is very important to choose the right professional spray gun for coloring, for this you should know a few rules.
First of all, it is recommended to pay attention to the material from which the device body is made. The best solution is a device with an aluminum body and a corrosion-resistant coating of nickel. Cases made of plastic have a lower mass, which, of course, makes painting the walls of the ceiling more convenient, but unlike the previous version, the plastic casing is short-lived. The holes in the spray lid can be made of aluminum, brass or stainless steel.
Spray guns differ in the location of the paint tank and the material of its manufacture. In modern models, the tank can be located above or below, which does not have a significant impact on the quality of painting. As for the material, metal cans are easier to wash, and transparent plastic can control the consumption of water-based paint.
Important! Sprayer housing with lower tank location must be held horizontally for greater convenience. When painting ceilings, this is problematic, so in this case it is better to choose a model with a lower tank.
Airbrush for water-based paint is represented by three varieties, which differ in principle of action:
- manual;
- electric;
- pneumatic.
Characteristics of manual spray guns
The manual spray gun has a simplified design, which includes a tank with an integrated pressure pump and a tube with a hose for spraying paint on the surface of the ceiling and walls. A manual device is the most budgetary, but it is quite difficult to work with it, since its resource is limited by the amount of compressed air, and every 5 minutes it is necessary to replenish it with a hand pump. Also a significant drawback of this device is the large dispersion of the surface to be painted, to reduce which it is recommended to use high-quality water-based paints and control their viscosity during the staining process.
Despite some difficulties in use, using this spray gun for an hour you can paint a surface of up to 250 sq.m.
to contents ↑Features of electric sprayers
Electric spray gun compared with a hand-held device greatly simplifies the painting of walls and ceilings with their own hands, especially for those who first decided to do such work. In addition, this device is irreplaceable for ceiling decoration - it is characterized by high performance and ease of use.
The device operates on AC 220 V and for its operation does not require auxiliary equipment, as is the case with a pneumatic sprayer. Staining can be done in two ways: by airless spraying and spraying due to low pressure, the first option is the most common. The manufacturers of the device have adjusted the nozzle diameter so that the work is as efficient as possible, so there is no need to worry about the quality of the jet.
By its design, the electric spray gun resembles a hair dryer, where a spray module is located at one end and a paint tank is fixed at the other. The main disadvantage of the electric atomizer is the need breed acrylic paints in water, as a result of which the viscosity of the composition decreases, and several layers of material have to be applied to the surface.
to contents ↑The specifics of using a pneumatic spray gun
Pneumatic sprayer is the most effective option not only for water-based paint, but also for all coloring materials. A professional airbrush allows you to process about 400 sq.m. within an hour, but at the same time its cost is much higher than electric and manual analogues.
The pneumatic apparatus works with the help of a compressor, which provides continuous supply of compressed air under high pressure, mixing it with paint and further spraying it onto the surface of walls and ceilings. Convenience and ease of use makes this device an ideal option for both professional finishers and beginners who decide to do the repair themselves. Before starting work, it is necessary to prepare material for coloring, for this water-based paint is diluted with water and mix well the resulting composition.
to contents ↑Advice! If you do not plan to paint walls and ceilings in a large room, and the work is one-time in nature, then it does not make sense to purchase an expensive pneumatic sprayer, in this case you can use a conventional hand-held device.
How to use a spray gun
In the process of using a spray gun, there are some nuances that affect the quality of work and require special attention:
- When painting the ceiling with your own hands, you can not hold the device for a long time in one area, otherwise drops will appear in this place that will violate the aesthetics of the coating.
- The stream of paint should be clearly perpendicular to the base, since the slope will increase the consumption of paint, which does not hit the walls, but splashes in the air and settles on objects located in the room.
- Painting must be done in a circular motion, constantly checking how evenly the paint lies.
- It is impossible to put the subsequent layer on the dry surface. The drying time of the paint is at least 5-7 hours, and in the case of water-based compositions - up to 12 hours.
- Before painting, it is necessary to thoroughly clean the base, remove small particles of dirt, dust and oil stains. If the technology is followed, the use of a spray gun will ensure high-quality repair work with your own hands and will help to significantly save paint.
Conclusion
As a conclusion, it can be noted that the airbrush serves as an indispensable assistant for home repairs, especially when it comes to high ceilings and large rooms. However, everyone who did this kind of work with their own hands encountered certain problems.
Sometimes in the process of painting, bubbles form on the surface, which, after drying, begin to crack and peel off the wall. In this case, it is recommended to clean the areas with cracked paint, after which it can be treated with putty, then sanded and painted again.
