Which spray gun is better for household purposes. How to choose a spray gun for your home: tips and tricks. Application of electric spray guns

If you are already puzzled by the choice of a spray gun, we need to give you credit. Indeed, despite its growing popularity, many professionals painting works still use a roller, which entails an increase in duration and a decrease in quality compared to work done with a spray gun. However, not every professional is able to navigate the diversity provided. Without studying in detail the characteristics and capabilities of the tool, you can throw money away and not get the desired result. Before comparing spray guns, let’s figure out how the device works and what its main functions are.

What is a spray gun?

The spray gun is, speaking in simple words, paint sprayer. All spray guns consist of a gun, a container for the solution and a device with which paint is pumped out of the container and pushed out of the gun nozzle. Thus, the sprayed paint lies in small droplets in a uniform layer on the surface. Spray guns are not only convenient to use, but also correct operation are able to provide a smooth, uniformly colored surface of large volumes in a short period of time. And the high cost will pay off due to the service life of the tool.

There are two main groups of spray guns based on the method of pumping and pushing paintwork materials:

• Air or pneumatic;
• Airless - electric and battery.

The design and operating features of both types are significantly different.

Painting the body with a pneumatic sprayer

Electrospray painting

Pneumatic

This spray gun works by compressed air, pumped by the compressor. The gun is connected to a compressor using a hose, which, in turn, is connected to electricity. Pressurized air converts the paint into tiny particles and pushes it out of the gun nozzle. Such tools cope with both large surfaces and small parts. The quality of painting significantly exceeds the quality of other methods, which is why they are widely used when painting cars.

Spray gun design air principle work

The main disadvantages of these spray guns are fogging and significant loss of paintwork materials at the output (up to 55%).

Considering that you are purchasing a gun and a compressor at once, the cost of the tool is undoubtedly higher. You also need to keep in mind that the compressor must match the characteristics of the gun, otherwise there is a risk of damaging the equipment. This fact further complicates the buyer's choice. But in return, the buyer receives a powerful professional device.

All available for sale Pneumatic guns are divided into main types:

• HP - technology high pressure;
• LVLP technology low pressure, small volume;
• HVLP - low pressure, high volume technology.

They differ in the pressure in the air chamber of the gun and the air consumed from the compressor.

HP - simplified technology. It is used in inexpensive pistols. The point is that high level pressure allows you to consume relatively little air. This makes for quick painting, but not the best best quality. The disadvantages of the technology are strong particle turbulence and fogging. Accordingly, we have wasteful use of paint. The percentage of its transfer to the surface is 45–50%.

A distinctive feature of LVLP technology is the highest quality atomization, low air consumption, and a significant reduction in fog formation. The percentage of paint transfer from some manufacturers reaches 90%. However, the operating speed is low due to the low pressure. Such sprayers belong to the highest price category.

HVLP is a modernized HP spray gun. The air enters the gun at high pressure and the paint is atomized at low pressure. excess pressure compressed air. Characterized by slight fogging and small losses of paintwork materials. The paint transfer rate is 65%. The quality of application is better. Their air requirement is less than that of HP pistols, but higher than that of LVLP. Such pistols have earned the title of “super economical”. They are most often used in car painting.

Electrical

These sprayers are powered by a built-in motor with a piston pump that forces paint into the nozzle. Of course, the quality of painting with an electrospray is inferior to pneumatic ones, since the paint particles are much larger due to the lack of compressed air. But you will receive an inexpensive device that does not require special maintenance or additional purchases except for material. These spray guns operate from a 220V network. Suitable for small surfaces and considered household.

Design of an airless spray gun

Electric spray guns can be: floor-mounted for professionals or hand-held for household purposes. Floor-standing have large installation with a container and a motor separate from the gun.

It is most convenient to use a sprayer with a transparent tank at home. This allows you to monitor paint consumption.

Comparison table of electric and pneumatic spray guns

How to easily decide on the choice of a successful model? Compare your goals and requirements for spray guns with the characteristics that the manufacturer offers us. To do this, let’s take a closer look at the instrument parameters that are important to pay attention to when purchasing it.

Purpose of work and purpose

To choose successful model tool, first of all, determine the purpose for which you decided to purchase.

For renovations in an apartment or house every 5 years, purchase costs pneumatic equipment with a compressor are not comparable to the result. Even if in the future you plan to periodically touch up something, it is better to purchase a standard electric spray gun.

For garage painting of cars, whether you are an amateur or a professional, contact the manufacturers of pneumatic sprayers. In painting parts, quality is the main indicator clean work. Inexpensive pneumatic devices, but always of a proven brand, cope with all stages of preparatory and finishing finishing better than others. The speed of painting will depend on many factors: torch size, outlet pressure, your skills.

Viscosity of compounds

Electric spray guns are more capricious when it comes to paint materials. The DIN viscosity index indicated in the passport of any spray gun must be no lower than the viscosity of your composition. Therefore, builders often resort to diluting paint with water. But thick compounds and putty will most likely not be applied with such devices.

Pneumatic spray guns are capable of working with more viscous compounds. However, here too everything depends on the type of gun, needle size and pressure. With high-pressure spray guns, the exiting jet of primer, paint, varnish or other viscous materials lies on the surface in an ideal layer, without drips, streaks or layers. As for low-pressure tools, while LVLP can be easily matched with thick paint, it won’t have enough pressure for putty.

Availability of adjustments

When choosing a spray gun, electric or pneumatic, be sure to check for adjustments. With their help, you can customize your device for the surface to be painted and the specific composition, changing the pressure, the limitation of the needle stroke, which is responsible for the supply of paint, the shape and size of the torch.

Also pay attention to the equipment included with the tool. It is best if the kit includes replacement nozzles with different diameters, a pressure gauge, and hoses of different lengths.

Tank location

When choosing a sprayer important has the location of the tank for the composition. It all depends on the distance and location of the surface to be finished. For example, when working with a device with a bottom-mounted tank, it is recommended to hold it strictly vertically to pump paint. However, the vertical position of the tank is inconvenient for painting ceilings.

Tool mobility

Do you ever find yourself spray painting away from electricity? You decide. For this case, we suggest getting acquainted with an airless battery spray gun.

What is its advantage? Of course, in mobility. But there are a number of disadvantages:

• Weight of the tool due to the presence of a battery;
• Low power;
• Limited operating hours;
• A drop in pressure when the battery is discharged and, as a result, poor-quality painting.

Therefore, even if you are going to perform only small household tasks, and the mobility of the tool is not in the first place, we recommend purchasing a spray gun from the category of household spray guns that operate from an outlet.

Performance and Power

Finally, when choosing a sprayer, often the first thing a buyer looks at is its performance and power. And here we need cold calculation.

When buying a pneumatic device, it is recommended to first purchase a gun, and then select a compressor based on its characteristics. Based on the performance indicators of the gun, that is, the air consumed, select a compressor with a “reserve”. If the compressor is selected incorrectly, the pressure drops too quickly or the motor operates at the limit, which can result in overheating, shutdown and early wear of the piston group.

When comparing tools, it is also worth paying attention to the fact that the company indicates input productivity in the passport. Depending on the model, losses occur due to air compression. Therefore, the actual output productivity is 65–70% of the specified one.

The compressor power averages 1.2–1.8 kW, which is enough to operate the entire unit. The volume of the receiver for most types of work is sufficient in the range of 24–50 liters.

With airless spray guns things are simpler. The manufacturer has provided and balanced the characteristics of the gun and the motor with the pump. Based on price and performance, you can choose the best device for yourself. But keep in mind: the greater the power and performance, the better the device will cope with thick compounds.

Experts advise adjusting the gun for each composition and material and testing it on a separate surface. Optimal choice needles - 1.3–1.4 mm.

Summing up the choice of a spray gun, we present to you the most popular proven brands of manufacturers that are in demand among professionals and amateurs.

• Bosch. The Bosch company produces inexpensive and compact spray guns with an electric motor for home use. Most famous models: PFS55, PFS65. The pump and motor of smaller power models are designed to be built-in. Bosch spray guns are used for treating the surfaces of walls and ceilings and for painting small parts. Average productivity is 0.11 l/min. The tools are easy to use and maintain. The main disadvantage of these spray guns is the restriction on the use of certain types of paints and varnishes, such as: alkaline, latex, dispersion paints and other difficult-to-spray compositions. Therefore, prices for spray guns start at 4,000 rubles.
• Wagner. German Wagner air spray guns are good competition for Bosh. Models costing from 5000 rub. (Wagner W550) are suitable only for liquid coatings, productivity is 0.13 l/min.

The product comes with additional components.
• Paint Zoom. In Russia the spray gun is also known as “SPECTRUM”. The cheapest and easiest to use electrospray. However, you should not rely on its reliability. Can be used to perform small-volume work that does not require high quality. The productivity of the spray gun is about 0.3 l/min. The cost of a spray gun is from 1000 rubles.
• Black&Decker. HVLP air spray guns of the American company have proven themselves in production painting works medium and large surfaces, especially on household level, in houses, apartments, dachas. But if available good experience they are also suitable for automotive painting. Popular models are HVLP200 with built-in compressor and HVLP400. Black&Decker spray guns are equipped with special system adjusting the configuration and size of the nozzle, which saves material. The tool can be easily disassembled and washed. The models belong to the middle price category of spray guns, and the cost starts from 4000 rubles.
• Elmos. Elmos airless spray guns are used in domestic environments. Good performance allows painting medium surfaces. The sprayer works best with paints on water based, varnishes and polishes. Thanks to the extended flexible nozzle, you can paint hard-to-reach places, horizontal and vertical surfaces without turning the gun over. The Elmos PG-80 model has proven itself well, with a capacity of 0.3 l/min, which is equipped with a special turbine that creates required amount air to increase dyeing speed. The cost of such a spray gun is from 4000 rubles.
• Sata. Chinese brand produces pneumatic spray guns of high and low pressure. Sata tools are suitable for professional painting work, for large and small surfaces. Maximum operating pressure 0.7 bar, a good uniform spray of paint and sufficient speed contribute to uniform application of the composition. Material transfer is more than 60%. It should be taken into account that it is for spray guns high blood pressure A fairly powerful compressor is required. Some models are specially designed for applying viscous compounds, thick paints or putties. The price of Sata spray guns ranges from 13,000–50,000 rubles.
• Walcom. Italian Walcom spray guns are designed to perform large volumes of painting work and are considered professional. There are several lines of sprayers on sale depending on their purpose. There are both basic models for primer and thin paints costing from 7,000 rubles, and sprayers for body work and aero design starting from 22,000 rubles. Spray guns are considered the most economical and environmentally friendly; paint transfer is more than 80%.

Before deciding which spray gun to choose, you need to pay attention to the following components:

1. productivity - the ability to cover as much area as possible with paint in a certain period of time;
2. power – the possibility of uninterrupted use of the device for at least half a working day (4 hours);
3. quality of coating - the higher the functionality of the spray gun to break the paint into the smallest particles, the better the paint coating;
4. ergonomics - ease of use of the device, which includes ease of operation, compactness, weight, ease of transfer from place to place, etc.

Considering that today there are only two types of spray guns (pneumatic and electric), then, based on the above criteria, understand how to choose an electric spray gun for home use or a pneumatic one for professional activity, it won't be difficult.

The pneumatic spray gun for painting a car and other surfaces is characterized by high performance, good power and high-quality application of the paint layer. This is achieved, first of all, by design features. In a sealed tank, called a receiver, pressure is created by pumping and compressing air using a pump. Compressed air is supplied to a small paint container built into the spray gun. When the trigger is pressed, the contents of the container are pressurized through the sprayer, creating fine particles of paint and evenly spraying over the entire painting area. Such paint sprayers perform well when used professionally. The only drawback is the limited working space due to the length of the hoses. For example, to paint a house you will have to drag all the equipment from place to place.

An electric spray gun, unlike a pneumatic one, has a simple design. In this type of spray gun, paint is pumped into the nozzle using small pump, built into the pistol body. It should be taken into account that due to the lack of a receiver for compressing and supplying air under pressure, paint spraying occurs at a lower quality than in pneumatic devices. However, if the question arose of which spray gun to choose for painting walls and periodic work around the house, then an electric spray gun is quite suitable for performing the assigned tasks. First of all, due to the fact that they are compact, lighter, easier to operate, convenient to move from place to place, and also much cheaper than pneumatic analogues.

Pneumatic spray gun: how to choose

Experts have no difficulty in choosing a spray gun for car painting and other professional needs. Because they know how to do it and are aware of the amount of work ahead. First, you should select a compressor based on receiver volume, maximum operating pressure and performance.

– if painting will be carried out on an industrial scale, then accordingly they opt for the largest stationary receiver with a volume of 300-500 liters with a maximum operating pressure of up to 10 atm and a compressed air capacity of more than 500 l/min. This will allow you to use several pistols in a fairly intensive mode;

– for workshops involved in bodywork, carpentry or fabrication wooden furniture a compressor with average performance is quite suitable: receiver – within 100 l, operating pressure – about 8 atm, productivity – 200-500 l/min;

- For finishing works and for home use, the question of which spray gun to choose for painting a house, windows, doors, floors and walls is easily resolved. That is, the most compact and lightest of compressors with a receiver volume of up to 50 l, operating pressure from 6 atm, productivity up to 200 l/min.

When choosing by performance, you should take into account that compressors indicate the air injection at the inlet - this is what you should select according to. If you need to find out the air flow at the outlet, then you need to multiply by a factor of 0.65-0.7.

The second part of the answer to the question of which spray gun to choose for painting a car, for finishing work, for a home or for painting walls, is to select a gun for the compressor. In other words, you will need to balance the selected air supply mode and the painting mode of the sprayer using the following three technologies:

– “high pressure” (HP) technology is based on supplying paint under high pressure up to 5-6 bar at minimum consumption compressed air. Shows well when painting industrial volumes in closed, unventilated rooms and workshops. It is characterized by a high consumption of dye, where about half ends up on the object being painted, and half evaporates into the air;

– “low pressure at high air flow” (HVLP) technology, where splitting paint and varnish material occurs due to the rapid supply of compressed air with a pressure of only 0.7-1 bar at the outlet. It is quite economical, versatile and effective, both on an industrial scale and in small-scale production, where losses due to spraying into the air are reduced to 35%;

– “low pressure at low air flow” (LVLP) technology, where atomization losses into the air are reduced to 20% with sufficient high speed work and high-quality paintwork. But it is practically not used on an industrial scale due to low efficiency.

Which spray gun is better from the above technologies is decided according to the conditions of the upcoming paint and varnish work.

Finally, the third part of the question, how to choose a spray gun for painting a house, car and other needs, is to select one or another design of the gun and nozzle:

– according to the location of the barrel: When positioned at the top, the gun is easy to use and speeds up the production of paint and varnish work, thanks to good unbalancing. However, the capacity of the tank is small, up to only 1 liter, and it also cannot be placed vertically during breaks in work. With the tank located at the bottom, the tank capacity is more than 1 liter and can be placed vertically during breaks in work, but it is a little heavy and less convenient to use;

– according to the diameter of the nozzle: for paint and varnish work, use replaceable ones with a hole diameter from 1mm to 3mm, or universal ones in the range of 1.4-1.7mm; for application and spraying building mixtures replaceable nozzles with a hole diameter of 6-7mm;

– according to the set of functionality: in this case, how to choose a spray gun is decided by the possibility of adjusting the stroke of the needle, by adjusting the power of compressed air supply to the nozzle, by giving one or another form of spray (torch).

How to choose an electric spray gun

Despite the fact that an electric spray gun is much simpler than its pneumatic counterpart, deciding which electric spray gun to choose has its own characteristics. The only plus is that there is no need to select a gun based on air supply power and tank volume, the manufacturer has already produced everything necessary calculations on balancing these components. All that remains for the consumer is to understand which spray gun is best to choose for painting a car or outbuildings, for use in decoration or for small household needs.

The first thing you should pay attention to is the capacity of the tank and its location. This will determine which spray gun to choose based on the volume of work to be done. For small jobs around the house and for household needs, a spray gun with a built-in tank with a capacity of about 1 liter or more is quite suitable when you need to paint small areas and surfaces. For finishing work, when periodically you have to paint fairly large areas of walls, doors, frames, ceilings and other elements of the room and facades, it is better to choose a spray gun with a separate floor tank with a capacity of 7-10 liters. And how to choose an electric spray gun for serious construction projects, a powerful electric spray gun without a tank will show you most effectively. The main unit of such equipment is placed on a wheelbase, a high-pressure hose up to 60 m long runs from a powerful pump to the gun, and the paint and varnish material is collected from any container, bucket, barrel of paint, etc.

The second criterion for the question of how to choose a spray gun for painting a car, walls and other surfaces implies what kind of paint will be used for the work. Some types of spray guns work only with water-based paints, others are more versatile and allow you to work with varnishes and solvent-based paints. If this is overlooked, the device may become unusable, since choosing a spray gun for painting a car from the line of spray guns for painting walls can lead to a negative result.

Third and no less important aspect The question of which electric spray gun to choose lies in the availability of various functional settings. At a minimum, it should be possible to adjust the paint supply volume and change the spray pattern (torch). At the same time, when purchasing, you should pay attention to the weight of the device, the level of vibration in the hand and the convenience of placing the handle in the palm - not only the quality of work, but also the comfort and labor intensity of painting surfaces largely depends on these little things.

First, let's look at the accepted designations for spray types - they directly indicate characteristics spray gun.

The most simple systems- This HP (High Pressure) spray guns. They are demanding on pressure and compressor performance; the operating pressure in the air head is higher than other types. Due to this, the paint breaks into small drops, gives a powerful torch, but also spreads it “by”. Therefore, these types of spray guns have the highest consumption of material; when working, we must not forget about a respirator and a hood. The surrounding area should be protected from pollination. But, for example, if you need good varnish breaking, then it won’t hurt to have an HP pistol in stock. A more interesting option for work is RP (Reduced Pressure). Essentially it's the same classic design, but working softer, pollination less.

HVLP (High Volume, Low Pressure) spray guns They operate at low pressure in the air cap, so their torch is soft and does not shoot far, and paint consumption is economical. On the other hand, it is already more difficult to create a “mirror” on the varnish. That is, for example, when painting metallic, it is more convenient to apply the base with an HVLP spray gun, and for varnish use the “good old” HP. Please note that the torch of such sprayers is “short”, and, for example, they are inconvenient to spray on the roof of a car.

What does it mean then LVLP? Based on the definition of Low Volume, Low Pressure, such spray guns not only operate at low pressure, but also supply the material in small quantities. Good option for small areas, with which it is better to work from a short distance. For example, when painting a forged lattice, more efficient spray guns will either instantly drip, or too much paint will “fly” into the free space. However, in any case, it is not the gun that paints, but the hand - a certain skill is always needed.

Electric spray guns- a specific thing. They are convenient primarily for large areas without special requirements to quality. For example, to paint walls with water-based paint using a pneumatic spray gun, you will need such a compressor that not everyone can drag it into an apartment. But an electric spray gun, which only a very undemanding person can use to paint a car, will help out here. Due to the low air pressure at the inlet, they have minimal pollination, which is important indoors. But productivity will allow you not to spend a lot of time on work.

Until recently, mechanized painting was considered possible in construction only on a huge production scale. However, the improvement of the method is gradually replacing the roller or roller methods in favor of special equipment, which allows you to quickly and efficiently spray not only paint, but also primer, anti-corrosion compounds, and putty.

What is a mechanical method of painting surfaces with paint?

Mechanized paint application involves the use of a special sprayer. The spray gun is most often used to treat large surfaces.

The mechanical method is used for painting and priming surfaces in apartments, houses, hangars and warehouses, offices, parking lots. This method is especially justified when processing outbuildings, building facades, fences and other large objects.

A paint sprayer is an expensive piece of equipment that requires certain operating skills, so when choosing this painting method, it is better to resort to the services of professionals.

Advantages

Mechanized painting has a number of advantages:

• high processing speed - up to 150 m2 per hour;
• economical paint consumption - about a quarter less than with any other method;
• uniformity of the resulting coating - thorough painting without streaks or missing spots;
• no hard-to-reach places - spray paint perfectly fills any shape.

Flaws

Disadvantages of using a spray gun:

• noise of the operating device;
• the high cost of purchasing or renting equipment, which is only advisable if it is necessary to paint a large area of ​​surfaces;
• operation on electricity, which can be a hindrance in a new building with an unstable network or forced outages.

Mechanized painting: how to apply paint

Mechanized painting devices differ in the spraying method:

1. Pneumatic spray. The essence of the device is to crush the jet into tiny droplets with a stream of air. Air spray guns of this type are divided into three types of international designations:

• HP (High Pressure), or conventional, transfers 30-45% of the paint and varnish material to the surface while the rest settles on the floor. International markings are white or silver.
• HVLP (High Volume Low Pressure) transfers the dye in an amount of about 70% and is marked in green.
• LVLP (Low Volume Low Pressure) is a device with improved operating pressure and compressor performance, which allows it to transfer up to 90% of the paint to the surface. Marking - blue.

1. Airless spray. The process occurs due to the pressure difference at the outlet of the paint from the nozzle. Airless spray guns give the most high percent transfer of paint to the surface, however, they require expensive components (pumping station, hoses, nozzles) and their thorough and labor-intensive washing.
2. Combined spraying. Distributes paint most evenly, combining airless crushing and dosed air flow at low pressure. The advantages of the method are less loss of dyes and greater flexibility of the sprayer, but a significant disadvantage is the high cost of the necessary compressors - piston and air.

How to choose a spray gun for painting

The range of paint guns is incredibly wide, providing users with many models, varying in price, method of application and technical specifications. It is difficult for amateurs to decide on a specific mechanism, so it is worth turning to a consultant for help, outlining the expected scope of work as clearly as possible. The main difference between sprayers is the type of compressor.

Positive displacement compressors

The mechanism of operation of a positive displacement compressor is to inject a fixed portion (volume) of gas and then displace it. The power of such mechanical devices depends directly on the frequency of filling and pumping out gas manipulations.

Dynamic compressors

Focused on a constant work process “in dynamics” for pumping a continuous flow of gas. The movement is carried out due to the functioning of a blade machine with a rotor responsible for the compressor power received at the output.

By type of drive mechanism: electric or mechanical

An electric spray gun, equipped with a simplified system for using the device, is becoming a frequent choice for beginners.

The simplicity of the device’s operation scheme allows you to master the spray gun in the shortest possible time. The main disadvantage of an electric sprayer is that it operates on mains power, which requires strict adherence to safety regulations when using flammable paints and varnishes.

A mechanical sprayer involves manually pumping pressure into the pump using a special lever. Due to this feature, it does not differ in accuracy, and is used either for a primer layer or finishing without requirements for the smoothness and accuracy of the coating.

Performance

The performance parameter shows how much paint the device applies to the surface per unit of time. The higher the spraying ability and, accordingly, the speed of painting, the higher the productivity. Spray guns of different systems operate on compressors of different capacities, so choosing a universal one will not work.

Even a compressor with the highest possible performance will not be suitable for all painting systems without exception.

When purchasing a compressor, you should make a choice based on the calculation of “maximum consumption of the spray gun + 20%,” which will be the minimum desired performance.

Cooling type

Sprayers are divided into devices with liquid or air type heat removal. Regulation of the operation of the cooling apparatus depends on the presence of the spray gun:

• pressure gauge safety valves;
• automatic shutdown functions when overheating;
• built-in fans and filtration systems.

Spray gun by application

The possibility of using a sprayer largely depends on the location of the container, which directly affects the quality of the liquid supply. So, a paint filling glass for water-based paint attaches to the spray gun itself. When using thicker paint and varnish material, the upper position of the container is justified, in which coloring matter flows due to its own gravity.

For water emulsion

A spray gun for water-dispersed compositions must meet the following requirements:

1. It is better to choose a paint tank and nozzle made of metal (aluminum, stainless steel, brass).
2. To prevent the gaskets from being damaged by the solvents contained in the water emulsion, make sure that they are made of a resistant material (for example, Teflon).

For enamel paints

An enamel sprayer must have a special marking indicating the device’s ability to work with viscous substances, which also include varnishes and metallic paints. The enamel will be sprayed in an even layer only if there is high pressure in the paint gun. In addition, it is necessary to take into account the severity of the enamel particles when applied to the wall.

The optimal distance between the spray gun and the wall should not be outside the range of 30-40 cm.

How to paint with a spray gun

The technology for using a paint sprayer consists of several sequential operations:

1. (protecting furniture and floors with film, applying masking tape along the boundaries of application, choosing protective equipment for a person - suit, glasses, respirator, gloves, etc.).
2. The second stage is a test application, which is necessary to check the condition of the device for tightness of fasteners and absence of leaks.
3. The spray gun container is filled two-thirds with the coloring composition; if necessary, paint is added during the process.
4. At the end of the work, it is necessary to pass a solvent through the system to remove paint residues and prevent sticking.

Airless application techniques

Airless painting occurs parallel to the wall surface in compliance with the following rules:

• fast movement to protect against drips;
• overlap the previous strip by 50% to avoid bald spots;
• Regularly clean the nozzle from blockages by turning it 180°.

Quick DIY painting

Self-painting using a spray gun will be of high quality with preliminary training on an unnecessary surface (remnants of drywall, utility wall, etc.).

It is possible to work out the best paints if the equipment is working correctly, then the process will not take much time. The best way to use the sprayer for the first time, it is a clearly defined surface, spray coloring composition which is needed from a distance of 15-20 cm.

Special requirements

The peculiarities of working with a paint sprayer for beginners are to follow recommendations for cost-effectiveness, since it is in this aspect that errors lead to an excessive increase in financial costs.

Before starting work, it is necessary to do a test painting, which will help to avoid the formation of spots of too thick application and the need to cover the uneven coating with an additional layer.

Choice the right tool- guarantee of easy and quality work, therefore, when selecting a paint sprayer, it is worth considering the most important indicators:

• compactness of the set;
• availability of a case for storage and transportation;
• correspondence of cost to available functions;
• ease of paint supply control;
• completeness of the set.

Thus, mechanized application using a spray gun has firmly entered the list of basic repair technologies that continue to improve and become available not only to professionals, but also to amateurs.
