How to spray paint at home. How to make a great atomizer from home remedies. For paint sprayer from a vacuum cleaner

To create a smooth and quality coating when painting with water-based or powder paint, experts recommend using a spray gun. But since many high-performance models cost a lot of money, it is advisable to make a real atomizer 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, while it will not be inferior to factory counterparts, and in some moments even surpass them, this applies, first of all, to the price of spray guns.

Homemade spray gun ideal for, for whitewashing with lime and others decorative coatings. Powder coating requires professional equipment with big power, but such designs can 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.

Sprayer from an aerosol can

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 improvised materials. For work, you need to prepare the following items: a plastic bottle, a bicycle inner tube, an aerosol can, for example, from a used deodorant, and a bicycle pump.

Work is performed in the following order:

• cut off a nipple with a cover with a diameter of 3 cm from the bicycle chamber;
• make a hole in the bottle;
• glue a nipple to the inner wall of the bottle, which will perform the function of forcing the air mass;
• cut out a spray module with a valve from a can with a hacksaw (the can must be selected so that its size matches the diameter of the cork from a plastic bottle);
• attach the valve to the plug by cold welding, while it is important to create an absolutely hermetic connection, since the structure will function under pressure;
• test the apparatus under pressure not higher than 3 atmospheres.

Homemade canister sprayer works like an airless sprayer and paints the surface like a paint job water-based composition, and when whitewashing with lime.

If it is planned to paint walls or ceilings in a large room, then working with a manual home-made sprayer will be quite problematic. In this case, you can try and make an apparatus with an automated air supply. To do this, you need a compressor from the refrigerator or old vacuum cleaner. Units made from a refrigerator or vacuum cleaner compressor do an excellent job with a water-based composition, 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, but also to the outlet, and they could function both for “blowing” and “blowing”. The models presented on the modern market do not have such capabilities.

If the use of the vacuum cleaner is no longer planned, then it is possible to change the direction of thrust in it, in some cases it will be enough to change the poles of the terminals that are connected to the stator and rotor. After that, it is necessary to carry out several operations that will allow you to fully use the old unit as an electric spray gun for painting:

1. Pick up 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 out a cork from the foam, which fits the size of the neck of the bottle. The cork 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 ensure the flow of 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 with a decrease in the volume of paint in a tightly closed vessel, a vacuum will occur.
5. Cut another foam plug that will combine the paint sprayer and the vacuum cleaner hose into a single system.

Refrigerator for the manufacture of airbrush

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

1. Take an old fire extinguisher, cylinder, canister or other tightly closed container as a receiver.
2. Remove the compressor and start relay, for this copper tubes bite or saw off with a hacksaw.
3. Turn on the power to determine which tube is supplying pressurized air.
4. Attach a car gasoline filter to the tube that sucks in air with a sealant or hose, which will protect the structure from dust.
5. Connect the air injection tube with two petrol hoses to the receiver. For this, fittings fixed with sealant are used.
6. Install a diesel filter, which can be purchased at an auto parts store, on the receiver outlet. The filter eliminates excess moisture in the incoming air and improves the quality of the airbrush.
7. Fix the compressor and receiver on a solid base, for example, on a board. After that, you can turn on the sprayer and start the painting process.

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

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

Spray gun holder

A simple do-it-yourself spray gun holder can be made from ordinary plywood sheet about a centimeter thick. For this you need:

• cut out a square of 25 x 25 cm from a sheet of plywood, in which to cut out with a jigsaw round hole, corresponding in size to the filling tank of the spray gun;
• insert the pistol handle into the groove cut from the edge of the plywood board to the hole;
• install a stand on legs made of wooden blocks, the height of which should be chosen so that there is space below for placing 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 plywood with screws.

Ballpoint pen sprayer

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

To make such an atomizer, you need:

• disassemble the handle and remove the paste from it, so that you end up with an empty tube through which air will pass unhindered;
• cut off the tip of the bottom of the handle to get an enlarged hole;
• disassemble the rod, remove the remnants of the paste from it with alcohol;
• in the center of the cork do through hole the same size as the rod;
• perpendicular to the hole for the core of the plug, a hole for the handle body is drilled;
• insert the rod and body into the bottle, after which you can start staining. The air in such a device will have to be inhaled on its own, so this method is not suitable for complex powder coating.

Making a spray gun for powder paint

Making a powder paint spray gun is not an easy task that requires professional skills and knowledge in the field of electricity. A common airbrush manufacturing technology includes the following tasks:

1. Assemble the electrical module. For this, the core is formed from a piece of plastic water pipe and a wire wound around it with a ferrite element. This module is placed in a plastic vessel and filled with paraffin.
2. Collect pistol. An electric core is mounted in a plastic tee, while it must fit very tightly into it. The walls from the inside 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, where the tank is inserted, while the flow of paint is regulated by a rubber trigger.
4. Separate the wires and close them on the power supply, after which you can start testing and filling the apparatus 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 its performance to ready-made models. And for small one-time works on painting with water-based paint, a simple spray gun from a pen or an aerosol can is quite suitable.

The advantages of the airbrush over traditional methods of applying paintwork are undeniable. The paint is applied evenly, without smudges. Both flat and embossed surfaces are equally well painted. Penetration of paint hard-to-reach places do not cause difficulties, in contrast to the work with a brush or roller.

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

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

Consider the design features that differ in the supply of working fluid to the atomizer.

Suction feed

The ink reservoir is below the nozzle, which either surrounds (diameter diameter) the supply tube or intersects with it at a 90 degree angle at a minimum distance. Pressurized air escapes from the nozzle, creating a vacuum in the supply tube.

Under the action of vacuum, the paint is sucked into the supply tube from the reservoir, captured by the air flow from the nozzle, and sprayed onto the surface to be painted in the form of tiny droplets.
This is the simplest way to spray the composition, previously used in hand sprayers.

Advantages - low manufacturability, and cost. Any size tank can be used by immersing a longer feed tube into it. The disadvantage is low productivity and poor ability to adjust the paint supply. The solution must be liquid.

With a sufficient diameter of the supply tube, 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 can of paint. Widely used in home painting.

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 the force of gravity. You can vary the shape and saturation of the torch, control the amount of supply of the coloring composition. Such an airbrush allows you to fill in a thicker solution.

The liquid in the tank should not contain large particles and 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 widely used in auto repair shops.

Pressure feed

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

This embodiment 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 simple to use, but requires a powerful compressor and a special paint tank that can withstand high pressure.

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

Painting a car is a complex 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 for many car owners who want to save money on painting services. If you turn to a professional camera, painting your car will cost several times more than you expected. In this case, most motorists begin to watch video tutorials and prepare for work with their own hands.

Doing the necessary work at home is difficult, but nothing is impossible. Design homemade devices for painting cars has become one of the most popular topics in all forums on this topic. It is interesting that many manage to assemble with their own hands even an airbrush, which performs household tasks quite efficiently. We will warn you right away that we will perform quality work and produce good painting machines using homemade tools is extremely difficult. For most people without experience, this will not be possible.

If you wondered how to make a spray gun with your own hands, you should immediately deal with technical issues. See what equipment you can use for this task. Create a device for yourself with your own hands painting work with a car is a bold and ambitious goal. There are several options for paint sprayers that you can do yourself. Let's take a quick look at the options for atomizers with a simple design:

1. Homemade tool from a ballpoint pen and foam. You can find a number of videos and instructions for building such a tool. But it’s better not to waste time, since you can only paint with it approximately.
2. Do-it-yourself spray gun from an aerosol can. It is advisable to take a bottle 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 is not suitable 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-working spray gun that can be restored. In this case, you can get fully functional equipment with a large list of benefits.
5. Use of commercially available parts to create a quality paint sprayer. This is quite a worthy option if you have the technical savvy and understanding of how such a device can be made.

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

Preparing equipment for painting your car with your own hands

Before deciding how to make an airbrush with your own hands, it is worth considering the rest of the set of devices. This may be a minimal paint supply kit, but it's 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 painting is carried out on the street, and the pressure from the compressor is uneven.

Therefore, for painting work, you will definitely need a room that can be dried. It should not have a lot of dust, and you can also come up with homemade equipment for injection high temperature. So the chamber will allow you to dry the car after painting. But not all actions can be performed with your own hands in order to achieve professional quality.

Where to get a compressor if there are no ideas?

One of the ideas for the production of a homemade simple compressor is a spare tire from the trunk of your car. Inflate with foot or electric pump pressure of 3 atmospheres, process the hose for connecting the spray gun so that it wraps around the wheel and presses the lever inside the device to release pressure. As long as the air descends to 2 atmospheres, you will have a certain time for applying paint.

Everyone can do this with their own hands. But you should also understand that the quality of painting your car 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 for painting, it is better to go to the station and order all necessary work.

How to assemble a spray gun for a car from improvised 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 completely presentable spray gun that can work much better than a regular spray can of paint. Of course, only the person who has a certain technical thinking and understands some of the complex aspects in this technique can assemble an airbrush with his own hands. Here is one of the options for making a part with your own hands:

1. Go to your local market and look for a quality water or pesticide sprayer with an adjustable spray pattern. The main thing is that the working mechanism is metal.
2. You will have to build a home-made hose mount from the compressor, so you will immediately have to choose the optimal components, nuts, gaskets for sealing. This will help to collect everything with your own hands.
3. You will also need a container for paint, which 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 the future gun from above 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 much streaks and gaps.

It is worth noting that even with a more or less correctly assembled pistol, it will be extremely difficult to get high work efficiency with your own hands. Painting homemade means rarely will you be satisfied with the results. So it's better to buy even a Chinese, but a factory airbrush and not invent a bicycle. But if you have all the details to create such a tool, you can try to make an airbrush for painting a car. At the same time, it is important not to spend money, but simply to test your technical abilities.

Summing up

As much as you would like to develop an efficient spray gun, manufacturing companies do it better. There are many interesting offers on the market, even in price categories up to 5000 rubles. Therefore, developing a home-made tool most often does not make sense. If you want to paint a car yourself, it is important to take into account all the subtleties of the equipment, find best option places to do this work. It is worth thinking about how well you can apply paint. The material for painting work is very expensive, and wasting it in vain is an unacceptable luxury for the owner of the car.

To make painting effective, use the services of specialized workshops. Often this is cheaper than organizing your own set of equipment. If you have a desire 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.

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

Manual spray gun: features and benefits of the tool

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

• body part - it is distinguished by the presence of two valves that pump air and suck in paint, this part freely rotates and changes the direction of paint supply;
• the 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, regulates the length of the tool itself;
• pump - located in the inner part of the housing, it works due to the interaction between the pistons;
• tank for paint;
• lid that closes the jar.

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 coloring can handle a manual spray gun;
• fast, uniform application of the coloring composition to the wall;
• The simple design of the manual lime spray gun allows you to quickly repair it in case of breakdowns.

However, the manual spray gun also has certain disadvantages:

• the manual process of work implies constant pumping of air, which is not very convenient during the work process, with pressure drops and surges, the jet turns out to be uneven, especially important for beginners;
• the possibility of using only water-based coloring compositions, only paints on water based or solutions for whitewashing, however, there is a wide variety of coloring compositions, with which staining is also carried out, they are not used in manual version paint cult;
• in the process of work, the so-called fog is formed, small particles of paint fall not only on the place of staining, but also settle on other objects, in order to avoid this, all objects located near the place of staining are covered with a polyethylene film.

Spray guns pneumatic, combined airless - 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 with the help of its own pressure, which is created inside the mechanism. In this case, the paint is split into small droplets covering the object. Among the advantages of this device, first of all, the absence of fog during the work process is noted. Also note the lack of the ability to adjust the size of the droplets. To obtain high quality staining, it is necessary to use expensive equipment.

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

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

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

If the amount of work is small, then make an airbrush from a pen. Such a device will work with a volume of paint up to one liter. In the process of work, you will need to have:

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

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

The tapered part of the handle also needs to be cut off, so you can get a good hole. Choose the diameter by trial and error, using a variety of pens, until the result of dyeing suits you.

To clean the rod from the paste, use alcohol, rinse it with it. Next, proceed to the construction of the body part of the spray gun. For these purposes, previously selected material is 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. For a tighter fixation of all parts, pre-spread them with glue, and then insert into a rectangle. The rod goes into the inside of the handle by three millimeters no more. The correct fixation of all parts among themselves is the result of the high-quality work of the mechanism.

Install the rod part in the reservoir containing the paint, fill it with compounds and blow into the paint spray tube. At the place where the parts are fixed, an air vortex will form, pushing out the paint of their tool. If the paint does not rise along the spray gun, then it is quite viscous, you need to take care of its additional dissolution.

Hand-held electric spray gun - we build it ourselves

If you have a special compressor unit, you have the opportunity self-manufacturing electric spray gun. It is highly functional and easy to use.

Of course, with the help of such an airbrush it will not be possible to paint a car with high quality, however, it is suitable for applying paint to walls, evenly distributing it over the surface. This airbrush does not need additional care, it is easy to fold and is unpretentious in operation.

For the manufacture of a manual spray gun, you will need:

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

In order to independently build a spray gun, follow these steps:

1. Install plastic cover on one bar, fix 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 used.

2. Install the rod inside the hole, the metal tip should protrude a few millimeters out of 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 with the help of subsequent rods. After that, connect the body part of the handle to the hose. Fix it in that position, at the exit of the steel tip from the rectangular area. The body of the pen is in contact with the tip so as to provide a slight protrusion above the edge surface.

4. Create an element to block the air flow. Thus, it is possible to improve the comfort of using the spray gun. No need to run to the compressor every time, if necessary, to stop the painting process. To do this, it is necessary to ensure the clamping of the hose and the air supply. To do this, build a few holes on the bar. One approaches the tip, and the second further. The hose enters through one hole and exits the bar through the second. Thus, it is possible to create a loop. At the same time, it turns out to automate the process of stopping the air supply from the compressor. Having installed a handle next to the hose, it is possible to pinch the hose with your fingers. This method is easier to perform.

After making the atomizer, connect it to a compressor, for example, from an old refrigerator or vacuum cleaner. The pressure in it will be about two atmospheres. With the help of this spray gun, it is possible to paint walls or the necessary furniture without any problems.

Do-it-yourself manual spray gun for whitewashing

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

A brass nozzle, made independently or purchased, will act as a tip. It is possible to manufacture several nozzle options, so the spray gun will have several modes of operation.

Next, you need to prepare the socket from the plug connector and install a tube inside it, the diameter of which is two millimeters. Build a metal bracket, 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 the tube that sucks in air currents. Make sure it is in the same position as the axle. Fix the tube to the socket with glue or with a soldering device. In addition, 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

For the manufacture of 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 perfectly cope with the functional load of the spray gun.

To achieve high-quality coloring and constant air supply, it is necessary to use a receiver. For this purpose, we recommend using soccer ball or rubber car tire. It is the receiver, with a 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. Such an airbrush allows you to paint walls, whitewash walls and even trees.

For the manufacture of an airbrush, a minimum of cost and time will be required, but its use in household matters is quite high. However, when performing staining, one should not forget about safety rules. For work, use overalls, a mask and a respirator, as small particles of paint can get into the eyes and respiratory tract.

Before starting work, check the paint for viscosity, too viscous composition will not be sprayed, clogging the spray gun. Adjust the nozzle on the gun to the size of the colorant jet. For these purposes, use a paper sheet. The interval between the spray gun and the surface to be painted is selected independently in the process of work. Drive the gun from the bottom up and vice versa, overlap the layers with each other. In order to achieve evenness and uniformity, at the moment when you drive the gun over the object, press it, when the spray gun stops, stop the paint supply.

In order to avoid repair of the spray gun, it is necessary to adhere to certain rules for its operation. First of all, use in working with homemade tool only water-based paints or lime. Wash tools thoroughly after use Special attention give the nozzle. Otherwise, there is an uneven distribution of paint or even clogging of the nozzle.

To wash off paints of different composition, use water or other solvents in the form of gasoline. Pay attention to the filter of the device - it must also be thoroughly washed. The paint used in the work should not contain lumps and foreign inclusions. In general, before starting work, check all parts for the absence of paint on their surface. If it does exist, use special solvents to remove dried paint from the mechanism. Only after that it is possible to assemble all the details 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 - an airbrush or a spray gun. It avoids the formation of irregularities on the painted surface. But since many factory models cost a lot of money, it will be more economical to assemble an airbrush with your own hands from improvised materials.

Airbrush at home

Such a design can be made from a variety of materials that most people have, for example, from a vacuum cleaner, a car camera, a refrigerator, a ballpoint pen, etc. In addition, such models will not be inferior to factory counterparts in any way and even surpass them to some extent. This applies directly to the price of such equipment.

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

Sprayer from an aerosol can

An aerosol spray gun is one of the easiest homemade options for water based paint. It will not be difficult to make it from improvised materials.

To create such an apparatus, it is necessary to prepare the following materials:

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

After preparing all necessary materials you can proceed directly to the execution of work:

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

Vacuum cleaner sprayer

In the event that you need to paint large surfaces, a manual sprayer is not suitable, as the process will be delayed. In such cases, it is necessary to manufacture a device with automatic system air supply. For these purposes, a compressor from a refrigerator or a vacuum cleaner is perfect. Such a "torch" at home is easy to make. Such designs are ideal for creating a home-made automated compressor that will cope with water-based paint, but they are unsuitable for powder.

For these purposes, old Soviet vacuum cleaners are suitable. Their advantages over the new ones are that the design of the new ones does not provide for two hoses: one for blowing in, and the second for blowing out.

In the event that 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 rotor. Next, you need to do a few things, 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 not more than 1.5 liters.
2. From the foam, cut a cork to fit 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 cars, and with the help of nozzles from a vacuum cleaner, you can change the direction and volume of the jet.

Refrigerator as starting material

This option is distinguished by great reliability and performance, it will work for a long time and benefit in 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, because in the end you can get a very good device.

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

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

Before starting work, you need to find a thing that will perform the function of the receiver. A fire extinguisher, a canister, or any container that can be hermetically sealed may be suitable for this.

Using a pre-prepared board, it is necessary to fix the compressor from the refrigerator on it. Next, you need to understand in which direction the device works, where the air comes from and where it enters. To do this, you need to connect it to the network and run it. The pipe from which air will come out will serve as an outlet. 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, which will tightly clamp the tubes, 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.

Two holes must be drilled in the receiver. A large hose is connected to one, which, in turn, is connected to the compressor inlet on the other side. A smaller hose is attached to the second hole of the receiver and the compressor outlet pipe from the back.

To control the pressure in the system, it is necessary to install a pressure gauge. Only then should the sprayer be connected. For mobility of the device, wheels can be attached to it.
