Spray gun for water-based paint: varieties and tips for choosing
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 decide on the choice of a sprayer, it is necessary to study its varieties, characteristics and features.
Operational scope of spray guns for paint
Paint sprayers 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 carried out. There are other areas of active use of water-based sprayers.
Painting walls, ceilings, fences and other structures manually is a laborious process. Spray guns can significantly speed up the work, which causes the demand for them among buyers. The use of this device allows you to reduce the overall consumption of paint. This is due to the uniform spraying of the material on the surface to be painted.
Useful information! Spray guns for painting are actively used in other areas. They are used to apply paint to various land and water vehicles: cars, motorcycles, boats, bicycles, etc. The use of a paint sprayer makes it possible to apply any kind of paint and varnish products on wooden, plastic and metal surfaces.
In construction, these devices are used for applying primer, paint and varnish. As well as spray guns are used for the restoration of furniture and household electrical appliances. This is easily explained by the fact that these devices allow you to apply a high-quality layer of paint that does not contain blurred or untreated areas. Such a procedure, performed at home, is in no way inferior to the factory one.
Antiseptic treatment of residential structures is also carried out with the help of spray guns for painting walls and ceilings. 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 paint, including water-based and oil compositions, but some models still have compatibility limitations. With the help of this device, varnish, liquid rubber, and primer are applied. The reliability and practicality of paint sprayers make them an indispensable device in many operational areas.
Advantages of using spray guns for painting
Many people 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 do the work quickly. 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 solid and uniform over the entire span of the surface. When painting the wall manually, it is almost impossible to achieve such a result, even if the work is performed by a qualified specialist. Such tools make it easier to work, so they have a lot of positive feedback. Spray guns allow you to apply the composition smoothly 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 and varnish material sprayed by means of a spray gun has a smaller thickness and is distributed more evenly. This contributes to the rapid drying of the composition.
And it is also worth noting another advantage of the paint sprayer – the ability to paint uncomfortable, embossed surfaces. A roller and a brush in this case cannot provide such an effective result.
Spray gun for water-based paint 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 flat, there are no streaks, drops, streaks and other irregularities on the wall that stand out against the general background.
Spray gun for water-based paint: varieties
To date, all devices of this type are classified into groups depending on the complexity of the design and the main technical characteristics. Regardless of what type of device is used to apply the coloring composition to the surface, they all allow you to work with water-based paint. There are 3 main types of these devices:
Useful information! Paint guns equipped with a manual drive include a suction sleeve. The design of this element takes into account the presence of a filter. The spray gun is equipped with a tank for paint and a pump, which is necessary for its spraying under a certain pressure.
The spray gun for this type of paint has a simple but effective design that allows you to do the work efficiently, 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 from which the housing is made, and the number of nozzles.
Paint sprayers that include an electric drive are more technologically advanced. First of all, this is expressed in the fact that their power can be different. Many users note the convenience of using electric sprayers for applying water-based compositions. The paint is supplied using a special diaphragm, or rather its vibrations. The cost of electronic models is higher than the price of manual sprayers. This is justified by the increased efficiency of this device.
Pay attention! When choosing an electric model, one important point must be taken into account: not every kind 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 function thanks to a compressor. This element is responsible for the supply of air compressed under pressure, which contributes to the spraying of paint. The average performance of this type of device exceeds by 2 times the performance of manual analogues and is 400 m2h. Such productivity favors the rapid application of paint to any surface.
How to choose a manual spray gun for water-based paint: recommendations
Manual models are great for working with a small area. With the help of such devices, you can paint, for example, a small-sized kitchen or bedroom. For large rooms, experts recommend purchasing pneumatic pistols equipped with a compressor. The application of water-based paint on the wall or ceiling is carried out mechanically. Thus, despite the presence of this device, you still have to work.
Manual spray guns for paint have one advantage over other types of devices: they are able to function for quite a long time. Moreover, if the spray gun is broken, then it is easy to fix it. Repair, as a rule, includes the replacement of a part that has failed. Budget hand-held devices are inexpensive. For example, in the construction market it is quite possible to find models whose price is about 1000 rubles. In turn, the cost of professional hand-held devices can reach 4000 rubles and above.
The housing of these devices is made of metal, which makes it possible to increase their resistance to mechanical influences (impacts). The design of the spray tube does not interfere with its free movement. The productivity 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, since it eliminates the need to install a ladder or other support for painting a high ceiling. Manual spray guns for water-based paint have proven themselves well in work. They are most often purchased for self-painting walls and ceilings.
There are some rules for working with this device. For example, experts recommend checking the container into which the paint is loaded for leaks before starting work. To do this, it is necessary to lubricate the cylinder and the accompanying sleeve with engine oil. Next, you need to 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 in pistols of this type to adjust the flow rate of the coloring composition.
Choosing an electric spray gun for water-based paint
Today there are many companies that produce electric spray guns for water emulsion. Among the variety of brands and models, the most popular devices produced by the following companies can be distinguished:
Pay attention! If the sprayed substance is a water-based paint, then the big role is played not by the type of device or brand, but by the size of the nozzle. 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 dilute the paint, following the instructions that in most cases are attached to it. The pressure injected inside the electric sprayer is the determining factor influencing the painting process.
The cost of electropulverizers directly depends on the pressure indicator. Therefore, before purchasing such a device, it is recommended to consider this criterion. Devices manufactured by popular companies cost at least 6000 rubles. It is important to remember that not every electronic device is suitable for working with a water emulsion. Electric paint guns are powered by 220 V. The process of applying the composition to a wall or any other surface can be carried out in two ways:
- by air;
Airless sprayers. One of the varieties of electric spray guns. Reviews of such devices are mostly positive. However, they have some features that you need to pay attention to before purchasing the tool.
In this case, the painting technology looks like this: the coloring composition is poured into and out of the tank (using a pump) it is supplied to the nozzle under high pressure. This technology eliminates the presence of compressed air, so no fog is formed during operation. This is a big plus, as it allows you to use paint as economically and efficiently as possible, which will not be sprayed into the surrounding space. The price of this type of electric spray gun is higher than for air analogues.
However, there is also a disadvantage of the airless method of applying water-based compositions. It consists in the fact that the surface after painting acquires a grain, becomes rough to the touch, like shagreen. It is because of this that spray guns with airless spray paint are most often used for outdoor work, where the result is not so noticeable. Spray guns for facade paint are used for painting the following structures:
Decorative roller for walls: features of using a painting tool
How to properly paint the walls with a roller without streaks. Features of ceiling painting.
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 paint sprayers are compact and versatile. The tank volume of such devices ranges from 0.8 to 1 liter, but there are exceptions.
Air sprayers. The difference between these devices and the first is the method of applying paint, which uses compressed air. Electric paint sprayers include a special compressor in their design. This element can be of two types:
Devices equipped with a remote 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 the reduced vibration level during operation of a paint gun of this type.
Let’s consider in which cases experts recommend using an air spray 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 situations where the work involves frequent changes of shades.
Pay attention! The main disadvantage of devices that spray paint with compressed air is the high consumption of the substance used. This is due to the fact that a cloud consisting of paint particles is formed during operation.
Sprayers belonging to the electrical group are recommended when lime is used as a finishing material. Spray guns for whitewashing with lime are most often used by specialized workers engaged in the repair of various institutions.
How to choose a pneumatic spray gun for water-based paint?
Pneumatic paint sprayers are the most effective. Using such a device allows you to paint a large area in a minimum time. They can be used to work not only with water-based paint, but also with other compositions. Experts emphasize 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 the paint. The power of the device can be different. The speed and quality of work depend on this indicator. Less powerful devices are suitable for non-professionals. The reduced pressure also allows you to expand the list of materials that will be compatible with the pneumatic device.
As for economy, these devices are able to reduce the consumption of paint consumed. The special design of pneumatic models makes it possible to exclude the dispersion of the composition into the air. Before buying a pneumatic spray gun, it is recommended to take into account the area of painting. Such devices are excellent 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.

How to choose a spray gun for water-based paint?
The appearance of the devices used for applying water-based emulsifiers to walls and ceilings does not stand out much among other types of sprayers. However, there are still differences. They are explained by some design features of the devices. For example, the structure of the air head in such devices differs from other tools. The design of the channels passing inside the spray gun is also unique.
The features in the structure of such models are due to the fact that they are specially designed for water-based paint. Therefore, it is very easy to work with it. It sprays well, does not clog the channels, and the final result pleases the eye. It is important to remember that conventional spray guns are not suitable for water emulsion, since 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 latter are easier to clean. However, plastic tanks have less weight and are transparent, which allows you to determine the level of the composition inside them.
The housing of the device must be made of metal with anti-corrosion properties. This will maximize the service life of the tool. Before purchasing a spray gun, it is also recommended to pay attention to what sealing elements it has. The effectiveness of wall painting with a spray gun depends on these details. Masters recommend choosing Teflon gaskets that 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 sprayer is suitable.
The main requirements that this tool must meet:
- small mass;
- having the right center of gravity (for ease of use);
- resistance to corrosion;
- equipped with different nozzles.
Which electric spray gun is better – battery or mains? 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 is poor performance. Such tools are great for small amounts of work. The volume of the reservoir in the battery devices does not exceed 1 liter. The battery charge is enough to work for 1-2 hours (depending on the model). In turn, network devices can function for 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 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 will not help in this case. It is necessary to use the option of electric tools.
Useful information! Which electric spray gun should I choose? Experts recommend purchasing models that are capable of pumping pressure above 4 atmospheres.
As for the manufacturers of electric models, the most popular among them are such brands:
Before you buy a spray gun for water-based paint, it is important to understand how much power the device has. Not all models are compatible with a water-based emulsion, so you should definitely consult with the seller about this before purchasing. For high ceilings, it is advisable to choose tools that have a long hose, otherwise you will have to use a stepladder or other means.
When using an electric sprayer, the risks of smudges, drops and other defects are minimized. Therefore, such devices are the most appropriate when painting ceilings. Manual spray guns are not suitable in this case, since they are not characterized by high quality of applying a layer of paint. In addition, they are not capable of pumping pressure exceeding the standardized indicator of 2 atmospheres.
Spray gun for painting walls and ceilings: compressor
This device largely determines how the spray painting will be done. Therefore, the selection of a compressor should 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 they do not directly affect the coloring process. It is important to remember that the operating pressure of the compressor is not at the same level during the 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 home, it is necessary to pay attention to the pressure change. Pressure fluctuations must necessarily be indicated in the technical data sheet that comes with the spray gun. In no case should you ignore this point.
Compressors for painting walls can have different performance. As a rule, this parameter depends on the power of the device. Performance data is indicated taking into account the standard temperature, which is 20 °C. This is very important, since this indicator can change at different temperatures.
Pay attention! 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 it is 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 they will not work in a single-phase network. To get acquainted with the operation of this device, experts recommend watching a video of painting with spray guns. They can be easily found on the Internet using the search bar of your browser.
The volume of the receiver. To maintain the desired pressure indicator, the compressors are switched off from time to time. Then they are turned on – and the work continues. The regularity of shutdowns directly depends on how much volume the air cylinder has. In this case, the following pattern can be traced: the smaller the volume, the more often the compressor is turned off.
Noise level. This indicator is not decisive, but 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, in which the principle of operation is based on the movement of the piston, then you will not be able to cope alone. You will need a second person who will be responsible for the air supply. It is also important to remember that this action must be carried out smoothly, otherwise the paint will be applied unevenly.
Many people are interested in the question of how to use a spray gun. In fact, the process looks very simple. You need to hold the device strictly perpendicular in order to achieve the highest quality result. If the tool is positioned unevenly, then there will be smudges. During operation, you need to change the position of the nozzle smoothly, without sudden movements. Otherwise, streaks will form on the treated surface.
Before starting work, it is recommended to make a trial staining. This will allow you to configure the paint sprayer. If you paint the walls, then you need to remember that you need to keep a certain distance to the ceiling and floor so as not to splatter them with the composition. The missing areas are then treated with a brush or roller. Electric spray guns for painting houses are the most effective, but they are more expensive than manual models. The choice of the device is made based on the volume of future work.
Pay attention! While working with the spray gun, you should not forget about the safety rules. It is worth preparing protective glasses, a respirator and gloves on your hands.
Painting is done 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 going to paint. It is necessary to clean them from wallpaper or any other coatings and eliminate minor defects. For this purpose, sandpaper is most often used. The surface should be as smooth as possible. If the painting is carried out in several layers, then it is necessary to wait for the complete drying of the previous layer. Only after that the next one is applied.
Be sure to read the instructions attached to the paint. Spray guns for thick or liquid formulations must 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 you to perform all actions in accordance with the instructions.
How to dilute the spray gun paint: tips
Several types of paint are used in construction. Each of the compounds has its own properties. The base for the paint plays a very important role, since it is this parameter that determines the operational scope of the substance. The following paint and varnish compositions are the most common:
- water – based emulsion;
The necessary consistency of the composition can be obtained with your own hands. The paint sprayer should be suitable for the viscosity level. The desired consistency is achieved by adding special solvents. They can be different depending on the type of paint.
Pay attention! It is important to remember that a solvent released by another manufacturer may not be suitable for the coloring composition. In order to eliminate incompatibility, it is recommended to purchase products from the same company.
Dilution of the paint is carried out clearly according to the instructions. It is advisable to consult with the seller when selecting a solvent, who will advise which of the compositions is most suitable for a particular paint.
For water emulsification, ordinary distilled water is most often used. In addition, it can be diluted with alcohol or essential solvents. Drying oil is used for oil paints. In this case, it is advisable to choose a spray gun with a metal balloon. In order to bring the oil paint to the desired consistency, you can use White alcohol.
Various compositions are used as a solvent for enamels. They may have a digital designation (for example, No. 645). And also for this purpose, solvents such as solvent, xylene and gasoline are suitable.
When choosing a spray gun for a water emulsion, it is necessary first of all to ask the question of 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 desired, you can always consult with a specialist who will help you choose the tool best suited to your situation.
