A spray gun is a device due to which painting of any surface is performed better. The equipment is a modern replacement for brushes and rollers and is a container with a mechanical part that feeds paint under pressure through a hose. Therefore, the working composition is applied evenly and in a thin layer.
To fully experience the benefits of a spray gun, you need to study its characteristics, functionality and model range. The tool is produced in several types, which differ in power and principle of operation. When choosing, it is important to take into account the amount of work, requirements for the quality of the coating and the experience of the master.

The types of equipment produced have a similar design and differ only in details. The main components of the spray gun are:
The tool breaks the material into small particles and transfers them to the surface through a nozzle that shapes the jet. Models differ in the need to build up pressure before painting. One type is connected to compressors, while the other is powered by turbines or built-in pumps.
You should not only know how to choose a spray gun, but also how to set it up. The adjustment is done with the screws on the back. As a result of the adjustment, the air jets located around the nozzle expand or contract the ink jet. For finishing a large area, the torch, that is, the stain of paint formed on the wall, must be wide. If the primary layer is applied, then a narrow torch is better.
The device on sale is divided into 3 types: electric, pneumatic, mechanical. There is also combined equipment, which combines several principles of pressure generation. A hand and floor spray gun is available.
Equipment also differs in the location of the tank: top or bottom. In the first case, the volume of the container is 1 liter or more. The device should be kept as level as possible and used when working with liquid formulations. The spray gun with the bottom tank is suitable for thick compositions. Small surfaces are painted with it, since the capacity is designed for 1 liter.
If ease of use is a key consideration when choosing equipment, you should pay attention to the electrical model.
This option is ideal for home use, since the power varies in the range of 0.18-0.27 kW, and the productivity is 255-265 m2 / h. The electric model does not require pressure control, and the flow rate is adjusted at the push of a button. The container is most often located at the bottom.
The pneumatic spray gun is equipped with a mini-compressor that blows air, due to which the paint is sprayed. Models of this type operate at low or high pressure. Low pressure guns provide a soft layering that covers the surface tightly. The equipment is economical in consumption, but the length of the standard hose included in the kit is usually not sufficient when processing large areas. Its length is only 5 m, so you have to buy extension cords.
The high-pressure sprayer even sprays materials with a dense structure, such as putty. Painting is faster, and the finish is good. The pneumatic device is used in everyday life and industry.
There are popular models for summer cottages - a battery spray gun, more mobile. In appearance, the device resembles a construction screwdriver. How long it will last depends on the size of the battery and its composition.
The mechanical device is operated manually by pressing the lever. Equipment of this type is used for whitewashing or finishing of outbuildings, when high precision and smoothness of the coating are not a priority. Regardless of the type of spray gun, it is important to observe safety precautions, as well as to know the selection criteria.
Not knowing which model is better to buy, they pay attention to the power. A spray gun with this parameter below 500 W is used exclusively for domestic needs. When purchasing a pneumatic model, the power of the connected compressor is taken into account.
The higher the power of an electric or cordless spray gun, the smoother the material lays down and the more comfortable it is to work. The optimal pressure for applying different types of paint is 4-5 atmospheres. Devices with a pressure exceeding 6 bar are convenient to use, but the loss of working composition reaches 40%.
The package usually includes a container, a pistol and a power supply system. Replacement nozzles, blowing nozzles and other accessories are sometimes purchased separately. The diameter of the nozzle is selected depending on the particle size of the composition:
Material | Solution type | Diameter, mm |
---|---|---|
Primer, whitewash, stain | Liquid | 0,8-1,2 |
Base paint, varnish | Middle | 1,3-1,6 |
Putty, resin, glue | Thick | 1,6-3,0 |
When buying a spray gun, it is determined whether you need an air or airless device. The first type is intended for high viscosity formulations, the pressure is 530 bar. The minus of the model is the poor quality of the coating, the formation of a fine mist during painting.
In hardware stores, there are budget and expensive models with a different number of functions. In order not to get confused among the wide range, it is important to know the device, which company is better and how much it costs.
The spray gun from the German company is popular among users due to its durability and reliability, excellent performance and high quality. The device is suitable for spraying paint on a medium area. The supply of the working composition is horizontal, vertical and point.

Before buying an apparatus, you should figure out how a spray gun differs from an airbrush. They are similar in design and material, but not in scope. The spray gun is designed for processing large objects, and the airbrush is for jewelry work.For example, painting a car. It is important to find an online store or a regular store where it is profitable to buy a device, since the cost can vary greatly.
When buying a spray gun, remember that the performance indicator reflects the amount of material being taken, not spraying. In fact, this parameter will turn out to be much less than the figure indicated in the passport. To work in any type of composition, it is better to purchase a device with a nozzle diameter of 1.3-1.5 mm.
The best manufacturers do not always provide the right model for a particular room. Therefore, the tool is chosen for the price, its characteristics, suitable for water-based paint or other composition. The rating of quality models introduces popular tools, and the choice is up to the buyer.
