Painting surfaces in rooms with a large area or high ceilings can be done using conventional brushes and rollers. However, such a solution is not advisable, since it takes too much time and effort to work. In this situation, it is best to use a spray gun for emulsion paint or any other composition. To determine the choice of spray gun (air brush), it is necessary to study its varieties, characteristics and features.
Operational field of spray guns for paint
Spray guns are common devices used in the construction field (and not only). The range of their application is very wide. With the help of such devices, not only internal, but also external finishing works are performed. There are other areas of active use of water emulsion sprayers.
Manual painting of walls, ceilings, fences and other structures is a laborious process. Spray guns can significantly speed up the work, which determines the demand for them among buyers. The use of this device can reduce the overall paint consumption. This is due to the uniform spraying of the material on the painted surface.
Useful information! Spray guns for painting are actively used in other areas. They are used for applying paint to various land and water vehicles: cars, motorcycles, boats, bicycles, etc. The use of a spray gun makes it possible to apply any type of paint and varnish on wooden, plastic and metal surfaces.
In construction, these devices are used for applying a primer, paint and varnish. And also spray guns are used for restoration of furniture and household electrical appliances. This is easily explained by the fact that these devices allow you to apply a high-quality paint layer that does not contain blurry or untreated areas. A similar procedure, performed at home, is in no way inferior to the factory.
Using spray guns for painting walls and ceilings, antiseptic treatment of residential buildings is also carried out. This procedure is performed from the outside of the buildings. Spray guns are often used to treat plants in the garden. This measure allows you to cope with insect pests.
Such a device can be used for all types of paints, including aqueous emulsion and oil formulations, however, some models still have compatibility restrictions. Using this device, varnish, liquid rubber, and primer are applied. Reliability and practicality of spray guns make them an indispensable device in many operational areas.
The benefits of using spray guns for painting
Many are used to painting various surfaces in the old way, using brushes and rollers. But this method is not convenient, and also does not allow you to quickly complete the work. The quality of the final result is much lower than when using specialized devices with which you can achieve a completely different effect. Paint sprayers have other advantages that you should pay attention to before purchasing the device.
The spray gun independently controls the distribution of paint. Therefore, its layer remains continuous and uniform over the entire gap of the surface. When painting a wall manually, it is almost impossible to achieve such a result, even if the work is performed by a qualified specialist. Such tools can simplify the work, so they have many positive reviews. Spray guns allow you to apply the composition evenly and efficiently.
Controlled spraying of the composition contributes to its economy. When using a spray gun, the paint consumption is reduced by at least 2 times, which, accordingly, reduces financial costs by a similar figure. The paint material sprayed by means of a spray gun has a smaller thickness and is distributed more evenly. This favors the rapid drying of the composition.
And also it is worth noting another advantage of the spray gun – the ability to paint uncomfortable, embossed surfaces. The roller and brush in this case cannot provide such an effective result.
Airbrush – is most often used in construction. It is used for painting ceilings and walls. The quality of the coating obtained as a result of working with this device is quite high. The layer lies evenly, smudges, drops, stains and other irregularities that stand out against the general background do not form on the wall.
To date, all devices of this type are classified into groups depending on the complexity of execution and basic technical characteristics. Regardless of what type of device is used to apply the paint composition to the surface, they all allow you to work with water-based paint. There are 3 main varieties of these devices:
- hand held;
Useful information! Manual spray guns include a suction hose. The design of this element takes into account the presence of a filter. The spray gun is equipped with a paint tank and a pump, which is necessary for spraying it under a certain pressure.
This type of paint spray gun has a simple but effective design that allows you to perform quality work, and in the shortest possible time. It is worth noting that the performance indicator of a good hand-held device reaches 200 m² / h. As for the price of such models, it varies depending on two criteria: the material of which the body is made, and the number of nozzles.
Sprayers for paint, including an electric drive, are more technological. First of all, this is expressed in the fact that their power can be different. Many users have noted the convenience of using electric sprayers for applying water-based emulsion formulations. The supply of paint is carried out using a special diaphragm, or rather its fluctuations. The cost of electronic models is higher than the price of hand sprayers. This is justified by the increased efficiency of this device.
Note! When choosing an electric model, one important point must be taken into account: not every type of water-based paint is suitable for devices of this type. In this regard, it is advisable to consult with the seller.
Pneumatic spray guns for painting walls and ceilings operate thanks to a compressor. This element is responsible for the supply of air compressed under pressure, which helps to spray paint. The average productivity of this type of device exceeds 2 times the performance of manual counterparts and is 400 m²h. Such productivity favors the rapid application of paint on any surface.
How to choose a manual spray gun: recommendations
Hand models are great for working with a small area. Using such devices, you can paint, for example, a small kitchen or bedroom. For large rooms, experts recommend purchasing pneumatic guns equipped with a compressor. The application of water-based paint on a wall or ceiling is done mechanically. Thus, despite the availability of this device, you still have to work.
Manual paint spray guns have one advantage over other types of devices: they are able to function for quite some time. Moreover, if the spray gun is broken, then it is easy to repair it. Repair, as a rule, includes the replacement of a part that has failed. Manual budget devices are inexpensive. For example, in the construction market it is quite possible to find models whose price is about 14,40$. In turn, the cost of professional hand-held devices can reach 57,64$. and higher.
The case of these devices is made of metal, which allows to increase their resistance to mechanical stress (shock). The design of the spray tube does not impede its free movement. The performance of such models can reach 150-200 m² / h. A long hose allows you to make the painting process as convenient as possible for the master, as it eliminates the need to install a ladder or other support for painting a high ceiling. Manual spray guns for aqueous emulsion ink have proven themselves in work. They are most often purchased for independent painting of walls and ceilings.
There are some rules for working with this device. For example, experts recommend checking the container into which paint is being loaded for leaks before starting work. To do this, lubricate the cylinder and associated sleeve with machine oil. Next, check the spray gun with water. During operation, it is not necessary to pull the trigger of the device, and a ball valve is provided for adjusting the flow rate of the coloring composition in pistols of this type.
The choice of electric spray gun
Today, there are many companies that produce electric spray guns for water emulsion. Among the variety of brands and models, the most popular devices manufactured by the following companies can be distinguished:
Note! If a water-based emulsion paint acts as a sprayed substance, then the size of the nozzle plays a big role not in the type of appliance or brand. This is due to the fact that the density of the composition may be different. This indicator affects the consumption of water-based paint and the final result.
It is recommended to breed paint, guided by the instruction, which in most cases is attached to it. The pressure injected inside the electric spray is the determining factor that affects the painting process.
The cost of electro-spray is directly dependent on the pressure indicator. Therefore, before purchasing such a device, it is recommended to consider this criterion. Devices produced by popular companies cost at least 86,46$. It is important to remember that not every electronic device is suitable for working with a water emulsion. Electric paint guns operate from a 220 V network. The process of applying the composition to a wall or any other surface can be done in two ways:
- by air;
Airless sprayers. One of the varieties of electric spray guns. Reviews about these devices are mostly positive. However, they have some features that you need to pay attention to before purchasing a tool.
In this case, the painting technology is as follows: the coloring composition is poured into the tank and from it (with the help of a pump) enters the nozzle under high pressure. This technology eliminates the presence of compressed air, so fog does not form during operation. This is a big plus, as it allows the most economical and efficient use of paint, which will not be sprayed into the surrounding space. The price of this type of spray gun is higher than for airborne counterparts.
However, there is a drawback to the airless method of applying water-based compositions. It consists in the fact that the surface after painting acquires granularity, becomes rough to the touch, like shagreen leather. It is precisely because of this that airless spray guns are most often used for outdoor applications where the result is not so noticeable. Spray guns for facade paint are used for painting the following structures:
- the veranda;
- farm buildings.
For painting surfaces that have a more complex shape and texture, as a rule, such devices are not used. For such work, models are used that can provide “soft” painting. Airless spray guns are compact and versatile. The volume of the tank in such devices ranges from 0.8 to 1 liter, but there are exceptions.
Air sprayers. The difference between these devices from the first lies in the method of supplying paint, which uses compressed air. Electric paint sprayers include a special compressor in their design. This item can be of two types:
Instruments equipped with an external compressor are less mobile. But users note that they are more convenient to use than devices with an integrated spare part. This is due to reduced vibration during operation of this type of paint spray gun.
Consider in which cases, experts recommend using an air gun. First of all, such a device will be more convenient if you need to paint a small area. When using paint with a liquid consistency, it is also better to purchase an electric spray gun for painting with a compressor. And also these models are recommended in those situations when the work involves frequent changes in shades.
Note! The main disadvantage of devices spraying paint with compressed air is the high consumption of the substance used. This is due to the fact that in the process a cloud is formed, consisting of particles of paint.
Sprayers belonging to the electrical group are recommended when lime is used as a finishing material. Spray guns for whitewashing lime are most often used by specialized workers involved in the repair of various institutions.
How to choose a pneumatic spray gun?
Pneumatic spray guns are the most effective. The use of such a device allows you to paint a large area in minimal time. They can be used to work not only with water-based paint, but also with other compounds. Specialists focus on the fact that a professional device is capable of painting up to 400 m² / h.
How to choose a pneumatic spray gun? Pneumatic paint guns have a compressor that compresses air under high pressure. Then this air is mixed with paint. The power of the device may be different. The speed and quality of work depend on this indicator. For non-professionals, less powerful devices are suitable. Reduced pressure also allows you to expand the list of materials that will be compatible with the pneumatic device.
As for economy, these devices can reduce the consumption of expended ink. The special design of the pneumatic models eliminates the dispersion of the composition into the air. Before you buy a pneumatic spray gun, it is recommended to take into account the area of painting. Such devices are great for both external and internal wall decoration.
The quality of work in this case depends on the professionalism of the master, as well as the viscosity of the colorful material. If all the rules are followed, there will be no smudges on the surface. The finish coating made by such a device is of high quality. For independent work at home, it is still recommended to use less professional equipment.
Bosch spray guns: characteristics and price
All electrical appliances manufactured by the German company Bosch are famous for their high quality. It is important to note that sprayers from this manufacturer include a minimum number of plastic parts, which increases their resistance to mechanical stress.
Air consumption during operation of Bosch spray guns is on average about 40 l / min. The nozzle in sprayers from the Bosch brand is located in front of the device.

How to choose a spray gun?
The appearance of the devices used for applying a water emulsion to the walls and ceilings does not stand out among other varieties of spray guns. However, there are still differences. They are explained by some features of the design of the devices. For example, the structure of the air cap in such devices is different from other tools. The design of the channels passing inside the spray gun is also unique.
Structural features of such models are determined by the fact that they are specially designed for water-based paint. Therefore, working with her is very simple. It is well sprayed, does not clog the channels, and the final result is pleasing to the eye. It is important to remember that conventional atomizers are not suitable for a water emulsion, as it has a high drying rate. In order to answer the question of which spray gun is better, it is necessary to focus on some points.
It is very important what material the paint container is made of. Plastic tanks are not considered as reliable and durable as metal ones. In addition, the second is easier to clean. However, plastic containers are lighter and transparent, which makes it possible to determine the level of composition inside them.
The body of the device must be made of metal with anti-corrosion properties. This will maximize the life of the tool. Before purchasing a spray gun, it is also recommended to pay attention to what it has sealing elements. The effectiveness of painting walls with a spray gun depends on these details. Masters recommend choosing Teflon gaskets, which are the most effective and durable.
For painting surfaces at home, you should not buy expensive models. For these purposes, a budget manual or electric spray gun is suitable.
The main requirements that this tool must meet are:
- light weight;
- the presence of the correct center of gravity (for ease of use);
- resistance to corrosion;
- equipped with different nozzles.
Which electric spray gun is better – battery or network? Devices that include a battery in their design are more versatile. The autonomy of such devices is a serious advantage, but they have one drawback, which consists in poor performance. Such tools are great for small amounts of work. The volume of the tank in the battery devices does not exceed 1 liter. The battery is enough to last 1-2 hours (depending on model). In turn, network devices can function an unlimited amount of time.
Features of choosing a spray gun for the ceiling
Most spray guns are universal. They can be used both for painting walls and for ceilings. If you need to paint only the ceiling, then you can purchase a device that is most suitable for this purpose. It is important to remember that manual models in this case will not help. You must use the option of electric tools.
Useful information! How to choose an electric spray gun? Experts recommend purchasing models that can pump pressure above 4 atmospheres.
As for manufacturers of electric models, the following brands are most popular among them:
Before you buy a spray gun for water-based paint, it is important to understand what power the device has. Not all models are compatible with the emulsion, therefore, before purchasing, you must always consult with the seller about this. For high ceilings, it is advisable to choose tools that have a long hose, otherwise you will have to use a stepladder or other tool.
When using an electric atomizer, the risks of smudges, drops and other defects are minimized. Therefore, it is precisely such devices that are most suitable for painting ceilings. Manual spray guns in this case are not suitable, since they are not characterized by high quality of applying a layer of paint. In addition, they are not able to build up pressure in excess of the standardized figure of 2 atmospheres.
Airbrush for painting walls and ceilings: compressor
This device largely determines how spray painting will be done. Therefore, the selection of a compressor must be taken seriously. When choosing a compression element, it is recommended to pay attention to several main factors, among which 3 main ones can be distinguished:
The auxiliary parameters of this device include its dimensions and weight. They are very important criteria, but do not directly affect the painting process. It is important to remember that the operating pressure of the compressor is not at the same level during application of the spray gun. It varies depending on the nature and duration of use of the device.
In order to answer the question of which is better to buy an electric spray gun for the home, you need to pay attention to the pressure change. Pressure fluctuations must be indicated in the technical passport that comes with the spray gun. In no case should you ignore this item.
Compressors for wall painting can have different capacities. Typically, this parameter depends on the power of the device. Performance data is based on a standard temperature of 20 ° C. This is very important, since at different temperatures this indicator can change.
Note! It is advisable to select a compressor with a small margin of performance. For example, HVLP devices need 350 liters of air per minute.
There are other characteristics of compressors that are recommended to pay attention to when choosing a device:
- receiver volume;
- noise level.
Voltage. Before you purchase a compressor, you need to ask how many phases are required for it. Some devices are compatible with three-phase power supply, so in a single-phase network they will not work. To get acquainted with the operation of this device, experts recommend watching a video of paint spraying. You can easily find them on the Internet using the search bar of your browser.
The volume of the receiver. Compressors are shut off from time to time to maintain the desired pressure reading. Then they turn on – and the work continues. The frequency of shutdowns directly depends on how much air the cylinder has. In this case, the following pattern can be traced: the smaller the volume, the more often the compressor switches off.
Noise level. This indicator is not decisive, however, it affects the possibility of convenient use of the device. It is recommended to select not very noisy devices, for this it is necessary to test the unit before purchasing.
How to paint with a spray gun : recommendations and algorithm of actions
If you have purchased a manual spray gun, for which the principle of operation is based on the movement of the piston, then you cannot cope alone. It will take a second person who will be responsible for the air supply. It is also important to remember that this action must be performed smoothly, otherwise the application of paint will be uneven.
Many people are interested in the question of how to use a spray gun. In fact, the process looks very simple. It is necessary to hold the device strictly perpendicularly in order to achieve the highest quality result. If the tool is not positioned smoothly, then smudges will appear. During operation, you need to change the position of the nozzle smoothly, without sudden movements. Otherwise, stains form on the treated surface.
Before starting work, it is recommended to make a test stain. This will adjust the spray gun. If you paint the walls, then you need to remember that you need to adhere to a certain distance from the ceiling and floor, so as not to splash their composition. Missed areas are then treated with a brush or roller. Electric spray guns for painting a house are most effective, but they cost more than manual models. The choice of device is based on the volume of future work.
Note! When working with the spray gun, you should not forget about the safety rules. It is worth preparing safety glasses, a respirator and gloves on your hands.
Painting is carried out in a ventilated room, so it is recommended to open the windows in advance. Before starting work, you need to prepare the surfaces that you are about to paint. It is necessary to clean them from wallpaper or any other coatings and eliminate minor defects. For this, sandpaper is most often used. The surface should be as flat as possible. If painting is carried out in several layers, then you must definitely wait for the previous layer to completely dry. Only after that the following is applied.
Be sure to read the instructions that came with the paint. Spray guns for thick or liquid formulations should be compatible with the viscosity index of the substance. Spray paint should not contain lumps, so it is recommended to clean it before use with a filter. Experts advise to perform all actions in accordance with the instructions.
How to dilute paint for a spray gun : tips
In construction, several varieties of paint are used. Each of the compositions differs in its properties. The basis for paint plays a very important role, since it is this parameter that determines the operational sphere of the substance. The following paints are most common:
- water emulsion;
The necessary consistency of the composition can be obtained with your own hands. The spray gun should be suitable for the viscosity level. The desired consistency is achieved by adding special solvents. They may be different depending on the type of paint.
Note! It is important to remember that a solvent produced by another manufacturer may not be suitable for the coloring composition. In order to eliminate incompatibility, it is recommended to purchase products of one company.
Dilution of paint is carried out clearly according to the instructions. When choosing a solvent, it is advisable to consult with the seller, who will advise which of the compositions is most suitable for a particular paint.
For a water emulsion, ordinary distilled water is most often used. In addition, it can be diluted with alcohol or ether solvents. Drying oil is used for oil paints. In this case, it is advisable to choose a spray gun with a metal cylinder. In order to bring the oil paint to the desired consistency, you can use white alcohol.
As a solvent for enamels, various compositions are used. They can be numbered (for example, No. 645). Also, solvents such as solvent, xylene and gasoline are suitable for this purpose.
If the liquid is sprayed in large drops or does not spray at all, add 5% of the appropriate solvent to the spray gun tank
When choosing a spray gun for an aqueous emulsion, it is first of all necessary to ask whether the device is compatible with such a composition. Further selection of the unit depends on the individual preferences of the master, as well as on the nature of the work and its quantity. If you wish, you can always consult with a specialist who will help you choose the tool that best suits your situation.
