The mains drive device has a limited scope. Therefore, carefully select the type of mixture for high-quality spraying on the surface. Thick mixtures and multi-component formulations with filler are not suitable for the apparatus. An electric spray gun for painting a car is best chosen for acrylic formulations.
It is convenient to apply paintwork on the surface of the machine using automatic mixture spraying devices. You can choose from several models of electric spray gun for painting a car. The main criteria are performance, cost and type of compositions for application to the surface of a car.
Features of the electric spray gun
The principle of operation of the device is mixing paint with compressed air in a chamber and spraying through a small hole - a nozzle. The pressure is created by a vibrating flexible diaphragm or a built-in compressor. The mixture begins to flow from a container located on the device or through a hose. The spray gun is controlled by an electronic button that regulates the flow of the working solution.
The device is powered by batteries or an external network. Typically, spray devices allow you to change the diameter of the nozzle outlet. The high pressure created in the chamber of the device allows you to evenly paint the surface. The characteristics of electrical and pneumatic devices are the same in terms of parameters. Therefore, the type of apparatus is chosen for operation, depending on access to communications - an air line or a household network.
Types of electric spray guns
The devices are economical, compact and with satisfactory coating quality.
Design differences of devices:
- Pressure in the mixing chamber by means of a vibrating diaphragm.
- With different arrangement of the tank with paint. For thick mixtures, it is preferable to receive the composition from the upper tank.
- With the ability to manually adjust the spray pattern using the adjustment buttons.
- Various weights: heavy floor-standing with a remote gun or small compact devices for beginners.
- Made from plastic or metal parts.
- A spray gun combined with a small mobile compressor.
Devices are also of two types: with spraying the mixture with compressed air and supplying paint to the nozzle using a pump.

- spare nozzles for applying the mixture.
Usually, complete with a spraying machine, they offer a spare tank, nozzles for nozzles with different hole diameters and a cleaning kit. The filter funnel insert cannot be reused. The stirring rod must be of a neutral material. When preparing the working mixture, it is necessary to check the viscosity with a viscometer in order to obtain a good quality coating without smudges and shagreen.
What paints to choose for an electric spray gun
The mains drive device has a limited scope. Therefore, carefully select the type of mixture for high-quality spraying on the surface. Thick mixtures and multi-component formulations with filler are not suitable for the apparatus. An electric spray gun for painting a car is best chosen for acrylic formulations.
Also, these guns are used for priming the metal plating of machines. The devices have good performance, therefore they are able to paint large surfaces with quick-drying mixtures until they set.
Instructions for using an electric spray gun
Before starting work, you need to put on personal protective equipment: overalls, shoes, gloves and a respirator. Prepare the components of the working composition, materials and fixtures.

Instructions for using the electric spray gun for beginners:
- Clean and degrease the treated metal surface. Grind rusty spots and even out defects.
- Prepare a working mixture from the paint components according to the recipe. Check the viscosity with a viscometer and add thinner if necessary. Pass the composition through the filter funnel.
- Adjust the size of the spray gun and the solution flow rate on the test surface. The paint should be applied in an even layer without smudges and roughness.
- Spray the mixture onto the metal surface with smooth overlapping movements. Direct the jet of paint vertically from a distance of 15-25 cm.
- After the end of the application of the paintwork, disassemble the spray gun and clean it from the remnants of the mixture.
Painting work must be carried out in a ventilated area.
Pros and cons of an electric spray gun for painting cars
Positive aspects of electric spray guns:
- the possibility of staining with a thin layer;
- no external source of compressed air required;
- small weight and size of the device, mobility;
- suitability for professional work.
Cons of devices with a network drive:
- large losses of the mixture during application;
- engine noise and body vibration;
- frequent clogging of nozzles;
- limited use of types of paints;

An electric spray gun is best used for painting cars with a primer and base acrylic enamel. Devices are usually not used for applying multi-component or filled formulations.
Which electric spray gun to buy
For household-powered devices, it is necessary to evaluate the requirements for auto-painting in terms of coating quality and productivity.
Let's review the parameters of popular electric spray guns:
- Compressor type with external or built-in arrangement.
- Power supply of the device from a stationary mains or battery.
- Permissible types of paint mixtures for use.
- The shape of the paint spray jet is round or elongated.
- The ability to adjust the power and flow of the mixture.
- Completeness - spare parts and a set of additional devices.
Spray guns with a built-in compressor are heavy and not designed for continuous operation. Battery power is convenient, but requires frequent recharging. Adjusting the shape of the torch allows you to paint complex surfaces. Additional devices are needed to prepare the solution and maintain the apparatus. An electric spray gun for painting a car is chosen based on price and customer reviews.
Preference Criteria
Coating devices for the metal surface of a car differ in their set of functions and performance. It is necessary to correctly consider the conditions for the use of materials and tools.
Parameters for choosing an electric spray gun:
- way to connect to power;
- engine power;
- pump type;
- the volume of the container with the composition;
- availability of additional features.
