How to spray paint at home. How to make a great spray bottle using home remedies. For spray gun from vacuum cleaner

To create an even and high-quality coating When painting with water-based or powder paint, experts recommend using a spray bottle. But since many high-performance models cost a lot of money, it makes sense to make a real sprayer from scrap materials.

Such a device can be made from a vacuum cleaner, a refrigerator compressor, a car camera, and even from an ordinary ballpoint pen, and it will be in no way inferior to factory analogues, and in some cases even surpass them, this applies, first of all, to the price of spray guns.

Homemade spray gun ideal for whitewashing with lime and others decorative coatings. For powder coating you need professional equipment with high power, but such designs can also be made at home. Therefore, for many it remains topical issue How to make a spray gun with your own hands and get a high-quality result.

Aerosol can sprayer

Hand sprayer made of aerosol can- This is one of the simplest types of homemade paint sprayer for water-based paint, which is very easy to make from scrap materials. For work, you need to prepare the following items: a plastic bottle, a bicycle inner tube, an aerosol can, for example, from used deodorant and a bicycle pump.

The work is performed in the following order:

• cut off the nipple with a cap with a diameter of 3 cm from the bicycle tube;
• make a hole in the bottle;
• glue a nipple to the inner wall of the bottle, which will perform the function of pumping air mass;
• Using a hacksaw for metal, cut out a spray module with a valve from a can (the can must be selected so that its size matches the diameter of the plastic bottle cap);
• cold weld the valve to the plug, it is important to create absolutely hermetic connection, since the structure will function under pressure;
• test the device under pressure no higher than 3 atmospheres.

A home-made spray bottle from a can works on the principle of an airless sprayer and perfectly paints the surface, just like painting. water-based composition, and when whitewashing with lime.

If you plan to paint walls or ceilings in a large room, then working with a hand-made homemade sprayer will be quite problematic. In this case, you can try and make a device with automated air supply. To do this you will need a compressor from the refrigerator or old vacuum cleaner. Units made from a refrigerator compressor or a vacuum cleaner do an excellent job with water-based paint, but are not suitable for powder paint.

Old Soviet vacuum cleaners have an advantage over modern technology in that their design involved connecting a hose not only to the inlet pipe, but also to the outlet, and they could function in both “blowing” and “blowing” modes. Models presented on the modern market do not have such capabilities.

If you no longer plan to use the vacuum cleaner, then you can change the direction of the draft; in some cases, it will be enough to change the poles of the terminals that connect to the stator and rotor. After this, it is necessary to carry out several operations that will allow you to fully use the old unit as an electric sprayer for painting:

1. Choose a bottle made of plastic or glass with a wide neck (at least 5 cm in diameter and up to 2 liters in volume).
2. Cut a cork from foam plastic that is sized to fit the neck of the bottle. The plug should have a rectangular ledge that allows you to insert a tube from a ballpoint pen or dropper into the hole at a right angle.
3. Make holes and insert tubes, one of which will supply paint, and the second will supply compressed air.
4. Make another auxiliary hole in the cork through which air will pass into the bottle, and when the volume of paint decreases, a vacuum will occur in a tightly closed container.
5. Cut another foam plug that will combine the paint sprayer and vacuum cleaner hose into a single system.

Refrigerator for making a spray gun

An electric spray gun made from a compressor from a refrigerator is much quieter than a vacuum cleaner and provides significant savings when painting. water-based paint And . But making such a device is much more difficult.

1. As a receiver, take an old fire extinguisher, cylinder, canister or other tightly closed container.
2. Remove the compressor and start relay, to do this copper tubes snacking or sawing off with a hacksaw.
3. Turn on the power to determine which tube supplies air under pressure.
4. Attach a car gasoline filter to the tube that sucks in air using sealant or a hose, which will protect the structure from dust.
5. Connect the air injection tube with two gasoline hoses to the receiver. For this purpose, fittings secured with sealant are used.
6. Install a diesel filter, which can be purchased at an auto parts store, at the outlet of the receiver. The filter removes excess moisture from the incoming air and improves the quality of the spray gun.
7. Secure the compressor and receiver to a solid base, such as a board. After this, you can turn on the sprayer and begin the painting process.

Advice! The compressor must be installed in the same position as it was in the refrigerator, otherwise the device will not start. In addition, the oil in the compressor spray gun must be changed periodically. For this purpose, there is a third tube, which is inserted into the housing.

The manufactured spray can be used equally effectively both for painting with water-based paint and for whitewashing with lime.

Spray gun holder

A simple holder for a spray gun with your own hands can be made from ordinary plywood sheet about a centimeter thick. To do this you need:

• cut a square measuring 25 x 25 cm from a sheet of plywood, and cut it out with a jigsaw round hole, the size corresponding to the filling tank of the spray gun;
• insert the gun handle into the groove cut from the edge of the plywood board to the hole;
• install the stand on legs made of wooden blocks, the height of which should be chosen so that there is space below to place the hose;
• To such a stand, you can additionally make a holder for a filter funnel; for this, aluminum wire is used, which is attached to the plywood with screws.

Ballpoint pen spray

A homemade spray gun based on a refrigerator compressor or vacuum cleaner is enough a complex system, which requires certain knowledge, but anyone can make a simple mini-spray from a ballpoint pen. This hand-held device is used with a small bottle of up to 1 liter, ideal for small finishing works, involving painting with water-based paint.

To make such a sprayer you need:

• disassemble the handle and remove the paste from it so that you end up with an empty tube through which air will flow freely;
• cut off the tip of the bottom of the handle to create a widened hole;
• disassemble the rod, remove any remaining paste from it using alcohol;
• make in the center of the traffic jam through hole the same size as the rod;
• a hole for the handle body is drilled perpendicular to the hole for the rod;
• Insert the rod and body into the bottle, after which you can begin painting. You will have to inhale the air into such a device yourself, so this method is not suitable for complex powder coating.

Making a spray gun for powder paint

Making a powder paint sprayer is not an easy task and requires professional skills and electrical knowledge. Common spray gun manufacturing technology includes the following tasks:

1. Assemble the electrical module. To do this, the core is formed from a piece of plastic water pipe and a wire with a ferrite element wound on it. This module is placed in a plastic vessel and filled with paraffin.
2. Assemble the pistol. An electric core is mounted into a plastic tee, and it must fit very tightly into it. The inside walls must be treated with glue to ensure the stability of the mechanism. All electrical wires are brought out through the lower holes, which are sealed with paraffin, and the exposed core is covered with a casing.
3. Connect the structure to the paint tank. A hole is drilled on the tee into which the tank is inserted, and the flow of paint is regulated by a rubber trigger.
4. Disconnect the removed wires and short-circuit them to the power supply, after which you can begin testing and filling the device with powder paint.

conclusions

Thus, making a spray gun with your own hands is a doable task. For more complex painting processes and frequent use, it is advisable to make a powerful electric spray gun from a compressor - such a unit is not inferior in performance to ready-made models. And for small one-time painting jobs with water-based paint, a simple sprayer from a pen or an aerosol can is quite suitable.

The advantages of a spray gun over traditional methods of applying paint and varnish are undeniable. The paint is applied in an even layer, without smudges. Both flat and embossed surfaces can be painted equally well. Penetration of paint into hard to reach places do not cause difficulties, unlike working with a brush or roller.

However, any convenient device costs money. Knowing the structure and operating principle of this tool, you can make a homemade spray gun literally from scrap materials that you simply throw away as unnecessary.

Types of spray guns according to the method of supplying the coloring composition

Let us consider the design features that differ in the supply of working fluid to the sprayer.

Suction feed

The paint container is located below the nozzle, which either surrounds (diameter in diameter) the supply tube or intersects with it at a 90-degree angle at a minimum distance. Air under pressure escapes from the nozzle, creating a vacuum in the supply tube.

Under the influence of vacuum, paint is sucked into the supply tube from the reservoir, captured by the air flow from the nozzle, and sprayed in the form of tiny drops onto the surface to be painted.
This is the simplest method of spraying the composition, previously used in hand-held sprayers.

Advantages: low manufacturability and cost. You can use any size tank by inserting a longer feed tube into it. Disadvantage: low productivity and poor ability to regulate paint supply. The solution must be liquid.

If the diameter of the supply tube is sufficient, a suspension of large paint particles is allowed. A typical example of use is a spray gun based on a vacuum cleaner and a lid for a paint can. Widely used in home painting work.

Gravity feed

The principle of operation is similar to the previous mechanism. Only the reservoir is located on top of the nozzle, due to which the coloring composition enters the spray formation chamber under gravity. You can vary the shape and saturation of the torch, control the volume of supply of the coloring composition. This spray gun allows you to pour a thicker solution.

The liquid in the reservoir should not contain large particles or lumps of undissolved paint. The construction cost is slightly higher. The disadvantage is that the volume of the tank is limited, since it is inconvenient to hold a large weight in your hand. This design is most widespread in auto repair shops.

Pressure feed

Compressed air is supplied directly to the paint tank, pushing it out with its pressure. Under high pressure, the coloring composition escapes from a specially shaped nozzle, forming a finely dispersed torch at the cut end. The saturation of the spray pattern is quite high, the shape and intensity can be adjusted by limiting the air pressure.

This design option is called an airless spray gun, since the spray cloud is formed not by mixing with air (according to the principle), but by a mechanical (injection) method. The system is quite easy to use, but requires a powerful compressor and a special paint tank that can withstand high pressure.

The paint must be homogeneous and completely dissolved. If it is impossible to properly prepare the solution, a filter is installed on the supply tube. This method of applying paint is widely used in aerosol cans.

Painting a car is a difficult and expensive task. It is necessary to take into account the quality of paint application; it is necessary to use the most technologically advanced equipment. A homemade spray gun has become a definite dream of many car owners who want to save money on painting services. If you hire a professional painter, painting your car will cost several times more than you expected. In this case, most motorists begin to watch video lessons and prepare to work with their own hands.

Carrying out the necessary work at home is difficult, but nothing is impossible. Design homemade devices for painting a car has become one of the most popular topics on all forums on this topic. It’s interesting that many people even manage to assemble a spray gun with their own hands, which performs everyday tasks quite well. Let us immediately warn you that to perform high-quality work and produce good paint job machines using homemade means is extremely difficult. For most people without experience this will be impossible.

If you are wondering how to make a spray gun with your own hands, you should immediately figure out technical issues. See what equipment you can use for this task. Create a device with your own hands painting works with a car is a bold and ambitious goal. There are several DIY paint sprayer options available. Let's take a quick look at the options for spray guns with a simple design:

1. A homemade tool made from a ballpoint pen and foam. You can find a number of videos and instructions on how to create such a tool. But it’s better not to waste time, since it can only be used to paint approximately.
2. DIY spray gun from an aerosol can. It is advisable to take a can of expensive paint, drill a hole in it for pouring paint, as well as for connecting a compressor. This is a working, but unprofessional tool.
3. Equipment from an old vacuum cleaner. Of course, such a solution will not work for a car, but at home it will be possible to carry out certain painting work and perform household tasks.
4. Option homemade device from an old non-functional paint gun that can be restored. In this case, you can get fully functional equipment with a long list of benefits.
5. Using commercially available parts to create a quality paint sprayer. This is quite a worthy option if you have technical savvy and an understanding of how such a device can be made.

Today we will talk more about the latter option, since only such a homemade spray gun can make it possible to repair a car body. In order for your DIY painting to be of more or less high quality, do not use the popular methods of creating devices from a ballpoint pen and a piece of foam plastic, which are revealed in dozens of videos. Such a device will definitely not be able to serve for a long time and give normal results.

Preparing equipment for painting your car yourself

Before deciding how to make a spray gun with your own hands, it is worth considering the rest of the set of devices. This may be a minimal set for supplying paint, but it is better to organize good camera, albeit homemade. It will be impossible to paint a car with your own hands with an even layer of paintwork if the painting is done outside and the pressure from the compressor is uneven.

Therefore, to carry out painting work, you will definitely need a room that can be dried. There should not be a lot of dust in it, and you can also come up with homemade equipment for injection high temperature. This will allow the camera to dry the car after painting. But you can’t do all the steps yourself to achieve professional quality.

Where can I get a compressor if I have no ideas?

One of the ideas for making a homemade simple compressor is a spare tire from the trunk of your car. Inflate using a foot or electric pump pressure of 3 atmospheres, treat the hose for connecting the spray gun so that it is screwed onto the wheel and presses the lever inside the device to release the pressure. While the air descends to 2 atmospheres, you will have a certain time to apply paint.

Anyone can do this with their own hands. But you must also understand that the quality of your car’s painting in this case will be very low. It is better not to resort to such perversions and use standard aerosol cans. If you have absolutely nothing to paint, it is better to go to the station and order all necessary work.

How to assemble a spray bottle for a car from scrap parts?

There can be many options for organizing a remote control for applying paint to car body parts. With your own hands you can assemble a quite presentable spray gun, which can work much better than a regular aerosol can of paint. Of course, only a person who has a certain technical mindset and understands some of the complex aspects of this technique can assemble a spray gun with their own hands. Here is one option for making a part with your own hands:

1. Go to your nearest market and look for a quality water or pesticide sprayer with adjustable spray pattern. The main thing is that the working mechanism is metal.
2. You will have to build a homemade compressor hose mount, so you will immediately have to select the optimal components, nuts, and gaskets for sealing. This will help you assemble everything yourself.
3. You will also need a paint container that will feed the material into the spray gun. It can be an ordinary plastic bottle, but it is better to look for something more reliable and presentable.
4. The paint container should be installed on top of the future gun so that the material flows freely into the supply chamber. In this case, a pressure supply will be organized in the lower or side part.
5. Can be used various options adjustments to get maximum performance and paint any surface without any streaks or gaps.

It is worth noting that even with a more or less correctly assembled pistol, it will be extremely difficult to achieve high efficiency with your own hands. Painting homemade means will rarely bring you satisfaction from the results. So it’s better to buy a factory-made spray gun, even a Chinese one, and not invent a bicycle. But if you have all the parts to create such a tool, you can try making a spray gun for painting a car. At the same time, it is important not to waste money, but simply to test your technical abilities.

Let's sum it up

As much as you might want to develop an effective spray gun, manufacturing companies do it better. There are many interesting offers on the market, even in price categories up to 5,000 rubles. Therefore, developing a homemade tool most often does not make sense. If you want to paint a car yourself, it is important to take into account all the details of the equipment, find best option places to do this work. It’s worth thinking about how well you can apply the paint. Material for painting work is very expensive, and wasting it is an unacceptable luxury for a car owner.

For painting to be effective, use the services of specialized workshops. This is often cheaper than organizing your own set of equipment. If you want to do this procedure often, organize a professional module for painting work. You will be able to buy all the necessary devices in the middle price range for little money.

Spray gun - universal tool for applying paint, which allows you to paint any object as quickly and efficiently as possible. However, buying a spray gun is an expensive process that is not always justified. It is much cheaper to make a spray gun yourself. We will learn further about how to build spray guns for various purposes.

Manual spray gun: features and advantages of the tool

A manual spray gun has a simpler structure than a pneumatic one. The principle of its operation is to push out the coloring composition with air. Among the main components of the spray gun are:

• body part - characterized by the presence of two valves that pump air and suck in paint, this part rotates freely and changes the direction of paint supply;
• pressure part in the form of a sleeve - is responsible for the pressure when supplying paint;
• suction part - has a filtration system that prevents clogging of the nozzle;
• fishing rod - has two parts, adjusts the length of the tool itself;
• pump - located in the inner part of the housing, works due to the interaction of pistons with each other;
• paint tank;
• a lid covering the tank.

Among the advantages of using a manual spray gun for paint, we note:

• affordable cost - this tool costs less than a manual pneumatic spray gun;
• ease of use - even a person with no experience in painting can handle a hand-held spray gun;
• quick, uniform application of the coloring composition to the wall;
• The simple design of a manual lime spray gun allows you to quickly repair it if breakdowns occur.

However, a manual spray gun also has certain disadvantages:

• the manual process of work involves constant pumping of air, which is not very convenient when carrying out the work process; when the pressure drops and surges, the jet turns out to be uneven, which is especially important for novice craftsmen;
• the possibility of using only water-based paint compositions; only paints on a water-based basis are placed inside the spray gun water based or solutions for whitewashing, however, there is a wide variety of coloring compositions with which coloring is also carried out; they are not used in manual version paint cult;
• During the work process, so-called fog is formed, small particles of paint fall not only on the painting site, but also settle on other objects. To avoid this, all objects located near the painting site are covered with a polyethylene film.

Pneumatic and combined airless spray guns - their features

Depending on the technology of spraying the coloring composition, spray guns are divided into three categories. The airless option involves pushing out the coloring composition using its own pressure, which is created inside the mechanism. At the same time, the paint splits into small droplets that cover the object. Among the advantages of this device, the absence of fog during the work process is noted first of all. They also note the lack of ability to adjust the droplet size. To obtain high quality dyeing, it is necessary to use expensive equipment.

The pneumatic method of spraying paint involves the action of air on the paint composition as it exits the nozzle. Air currents under high pressure push out the paint by spraying it. At the same time, the paint splits into small elements, forming a cloud. Most of paint settles on the object that is being painted, but small particles also fall on foreign objects. This option equipment is budget-friendly, but at the same time has high performance in the work process. In this case, the paint consumption is quite large, so the equipment is rarely used in everyday life, and is more suitable for industrial painting.

Combined devices are often used; the principle of their operation is to move paint through a mechanism without contact with air, however, at the exit from the device they are acted upon by a pneumatic element that pushes the paint out great strength. Thus, it is possible to save workplace clean, there is no foggy cloud, significant savings in the coloring composition are achieved.

Do-it-yourself hand-held spray gun for water-based paint

If the amount of work is small, then make a spray gun from a handle. Such a device will work with a volume of paint up to one liter. During the work process you will need:

• regular ballpoint pen;
• a piece of rubber, plastic or foam - rectangular in shape.

At the bottom of the handle you need to remove the tip. Remove the paste from the empty tube. If you cannot remove the rod, cut it off. The air flow should pass freely through the cavity of the tube without delay.

The cone-shaped part of the handle also needs to be cut off, this way you can get a good hole. Choose the diameter through trial and error, using many pens, until you are happy with the color result.

To clean the rod from the paste, use alcohol and rinse it with it. Next, proceed to the construction of the body of the spray gun. For these purposes, previously selected material will be required. Using a drill, drill a hole in the wall of the rectangle; the diameter of the hole should be such that a tube with a rod passes through it. To fix all parts more tightly, first coat them with glue and then insert them into the rectangle. The rod extends into the handle no more than three millimeters. Correct fixation of all parts among themselves is the result of high-quality operation of the mechanism.

Place the rod part in the tank containing the paint, fill it with compounds and blow into the paint spray tube. An air vortex will form at the place where the parts are fixed, pushing out the paint on the tool. If the paint does not rise up the spray gun, then it is quite viscous; care must be taken to further dissolve it.

Manual electric spray gun - we build it ourselves

If you have a special compressor unit, you have the opportunity self-made electric spray gun. It is characterized by high functionality and ease of use.

Of course, with the help of such a spray gun it will not be possible to paint a car efficiently, however, it is suitable for applying paint to walls, distributing it evenly over the surface. This spray gun does not require additional maintenance, is easy to fold and is unpretentious in operation.

To make a hand-held spray gun you will need:

• several gel pen refills;
• handle body;
• thin hose, about 25-30 cm long;
• several blocks;
• self-tapping screws, with the help of which the parts are fixed to each other;
• plastic bottle cap;
• several metal strips, 2 mm thick.

To build your own spray gun, follow these steps:

1. Install plastic cover on one block, secure it with self-tapping screws. Install the fasteners so that a small hole is drilled in the center of the cover. After fixing the cover, use a drill to create a hole. Please note that the diameter of the hole must match the diameter of the rod from the handle being used.

2. Place the rod inside the hole, the metal tip should protrude a few millimeters from it. Do not throw away the steel tip, as in the first case, the paint will flow through it more evenly.

3. Next, the rod is built up using subsequent rods. After this, connect the body of the handle with the hose. Fix it in that position, at the exit of the steel tip from the rectangular section. The body of the handle is in contact with the tip so as to provide a slight protrusion above the surface of the edge.

4. Create an element to block the air flow. Thus, it is possible to improve the comfort of using the spray gun. There is no need to run to the compressor every time, if necessary, to stop the painting process. To do this, it is necessary to ensure that the hose is clamped and air is supplied. To do this, make several holes on the block. One is closer to the tip, and the other is further away. The hose enters through one hole and leaves the block through the second. Thus, it is possible to create a loop. At the same time, it is possible to automate the process of stopping the air supply from the compressor. By installing a handle next to the hose, you can pinch the hose with your fingers. This method is easier to implement.

After making the sprayer, connect it to a compressor, such as from an old refrigerator or vacuum cleaner. The pressure in it will be about two atmospheres. With this spray gun you can easily paint walls or necessary furniture.

Do-it-yourself manual spray gun for whitewashing

We offer another option for manufacturing a universal mechanism, with which you can not only paint, but also whitewash walls. Using this method of manufacturing a spray gun, it is possible to improve the versatility of the design. First of all, for work you will need a plastic or glass reservoir for liquid, the diameter of which is at least 3 cm. In addition, you need to prepare a copper or aluminum tube with a diameter of 4 cm and a length of 200 mm. The tube must be bent and connected to a spray bottle or a hose from a vacuum cleaner.

The tip will be a brass nozzle, made independently or purchased. It is possible to manufacture several variants of nozzles, thus the spray gun will have several operating modes.

Next, you need to prepare a socket from the plug connector and install a tube inside it, the diameter of which is two millimeters. Build a metal bracket and connect one end of the tube to the conical part of the mechanism.

Connect all the previously prepared elements of the manual whitewash spray gun, set up a tube that sucks in air flows. Make sure it is located in the same place as the axle. Fix the tube to the socket using glue or a soldering device. Additionally, install a nut on the connection. Check the functionality of the device. Spraying should be uniform and of high quality.

Features of choosing a compressor and repairing a manual spray gun

To produce a high-quality spray gun, it is necessary to choose the right compressor that provides a certain pressure for spraying paint. Older models of vacuum cleaners have the function of not only blowing, but also blowing air. The compressor from them will cope perfectly with the functional load of the spray gun.

To achieve high-quality coloring and constant air supply, you must use a receiver. For this purpose we recommend using soccer ball or rubber car tire. It is the receiver, the pressure reducing valve, that regulates the air supply to the spray gun. All parts must be tightly connected to each other. Having achieved this condition, it is possible to obtain a high-quality supply of paint from the mechanism. This spray gun allows you to paint walls, whitewash walls and even trees.

Making a spray gun will require a minimum of cost and time, but its usefulness in household matters is quite high. However, when performing coloring, you should not forget about safety rules. For work, use special clothing, a mask and a respirator, as small particles of paint can get into your eyes and respiratory tract.

Before starting work, check the paint for viscosity; a composition that is too viscous will not spray, clogging the spray gun. Adjust the nozzle on the gun to the size of the spray of paint. For these purposes, use a piece of paper. Select the interval between the spray gun and the surface to be painted yourself as you work. Move the gun from bottom to top and vice versa, overlap the layers together. In order to achieve evenness and uniformity, at the moment when you move the gun over the object, press it, and when you stop the spray gun, stop feeding the paint.

In order to avoid repairing the spray gun, you must adhere to certain rules for its operation. First of all, use it when working with homemade instrument only water-based paints or lime. After use, wash the tool thoroughly, Special attention pay attention to the nozzle. Otherwise, uneven distribution of paint occurs or the nozzle becomes completely clogged.

To wash off paints of different compositions, use water or other solvents in the form of gasoline. Pay attention to the filter of the device - it must also be washed thoroughly. The paint used in the work should not contain lumps or foreign inclusions. In general, before starting work, check all parts for absence of paint on their surface. If it still exists, use special solvents to remove dried paint from the mechanism. Only after this can you assemble all the parts into a single mechanism and start working with the device.

In order to paint with high quality, any experts in this field advise using additional equipment - a spray gun or spray gun. It avoids the formation of unevenness on the painted surface. But since many factory models cost a lot of money, it will be more economical to assemble the spray gun yourself from scrap materials.

Spray gun at home

Such a design can be made from a variety of materials that most people have, for example, from a vacuum cleaner, car camera, refrigerator, ballpoint pen, etc. Moreover, such models will be in no way inferior to their factory counterparts and even surpass them to some extent. This directly concerns the price of such equipment.

A hand-made spray bottle is ideal for painting with water-based paint, for whitewashing or other necessary work. Powder paint, in turn, requires more expensive, high-quality and powerful equipment. Therefore, for many it remains interesting question on how to make a homemade spray gun with your own hands.

Aerosol can sprayer

An aerosol can sprayer is one of the simplest homemade options for water-based paint. Making it from scrap materials will not be difficult.

To create such a device, you need to prepare the following materials:

• bicycle camera;
• plastic bottle;
• bicycle pump;
• aerosol can (for example, deodorant).

After preparing everyone necessary materials You can proceed directly to the work:

Such a spray can will cope perfectly with the assigned tasks: painting with water-based paint and lime.

Spray bottle from a vacuum cleaner

If you need to paint large surfaces, a hand sprayer will not be suitable, as the process will be delayed. In such cases, it is necessary to make a device with automatic system air supply. A refrigerator compressor or vacuum cleaner is perfect for these purposes. It is not difficult to make such a “torch” at home. Such designs are ideal for creating a homemade automated compressor that will cope with water-based paint, but they are not suitable for powder paint.

Old Soviet vacuum cleaners are suitable for these purposes. Their advantages over the new ones are that the design of the new ones does not provide for two hoses: one for “blowing” and the second for “blowing”.

In the case when the old vacuum cleaner is no longer needed, in order to change the direction of inflation, sometimes it is enough to simply change the direction of the terminals that connect the starter and the rotor. Next you need to do a few steps, thanks to which you can use an old vacuum cleaner to paint surfaces:

1. Prepare glass or plastic bottle with a neck diameter of at least 4 centimeters and a volume of no more than 1.5 liters.
2. Cut a cork from foam plastic to the diameter of the bottle opening.
3. Make two holes, one of which will supply compressed air, and the second - paint.

Such a device is perfect as a spray gun for painting a car, and with the help of attachments from a vacuum cleaner you can change the direction and volume of the jet.

Refrigerator as raw material

This option is characterized by great reliability and performance; it will work for a long time and bring benefits to household. But on the other hand, its production will require a lot of effort and energy, as well as time. Although it is worth it, since in the end you can get a very good device.

To make a spray bottle from refrigerator elements, it is necessary to prepare the appropriate materials and tools:

• large container for paint;
• one hose 45 centimeters long and two 15 centimeters long;
• several clamps;
• machine gasoline filter;
• steel wire;
• screws;
• board.

Before starting work, you need to find something that will serve as a receiver. A fire extinguisher, a canister, or any container that can be hermetically sealed may be suitable for this.

Using a pre-prepared board, you need to attach the compressor from the refrigerator to it. Next you need to understand in which direction the device operates, where the air comes from and where it enters. To do this, you need to connect it to the network and start it. The pipe from which the air will come out will serve as an exit. The second tube will be the inlet, and the third on such compressors is closed.

It is necessary to connect hoses to the inlet and outlet openings, which will clamp the tubes tightly, and additionally clamp the joints with clamps.

As for the third closed tube, it serves to lubricate the compressor itself, and it is not recommended to touch it until the first malfunctions appear.

You need to drill two holes in the receiver. A large hose is connected to one, which, in turn, on the other side is connected to the inlet pipe of the compressor. A smaller hose is attached to the second hole in the receiver and the compressor outlet pipe on the reverse side.

To monitor the pressure in the system, it is necessary to install a pressure gauge. Only after this should you connect the spray gun. For mobility of the device, you can attach wheels to it.

Making a spray bottle at home is not a lot of work with a little effort.

From a ballpoint pen

You can also make a spray gun with your own hands at home from a ballpoint pen. This is the most primitive version of such a low-pressure device.
