To apply the paint in an even layer, you need to use a spray gun. This device can be purchased from a specialized store. The cost of this equipment is high. Therefore, many decide to make a spray gun with their own hands. To do this, various improvised means are used. How to create an airbrush will be discussed further.
Product Features
Do-it-yourself paint spray gun for a car or for repairs can be made from various improvised means. This device is a spray gun that is used in the process of painting different surfaces.
Hand sprayer is sometimes used for watering houseplants. More powerful varieties are suitable for painting different surfaces. This equipment allows you to apply a uniform layer of paint. The spray method is very convenient. As a result, it turns out to process different surfaces quickly, and the result will be high.
Atomizersuitable for paints and varnishes, as well as water-chalk or water-lime based products. There are several popular ways to create a spray gun. Various improvised means will be used. You can choose the best option for yourself.
Regular pen
How to make a spray gun with your own hands? There are several options for such structures. One of the easiest ways is to use a ballpoint pen. This is the most primitive design. You can assemble it in just 30 minutes.
The principle of operation of such a device is simple. A person blows into the tube of the pen body. Through it, on the other hand, splashes of paint break out. It is necessary to blow the material with high intensity. If you do this sluggishly, the drops of paint will not spread evenly over the surface. You can practice before you start.
To make a similar spray gun, you will need to purchase:
- regular gel pen,
- a container into which the paint will be poured,
- a needle from an ordinary syringe.
A small bottle can be used as a container. It should have a lid. It is better to prepare a needle not one, but several. They may break during the operation of the device.
Assembling the model
When creating a small spray gun for painting with your own hands, you need to perform several sequential steps. First you need to prepare the bottle cap. A hole is cut in it as wide as the core of a gel pen.
The tube will be inserted into the cut hole. You need to disassemble the gel pen. Its core will be in the cork. The body of the handle will be brought to it. For this, a medical needle was needed. It is put on with a wide end on the core of the gel pen. The needle is inserted into the body of the pen. Its tip should come out from its thin side.
You need to properly prepare all the components. Having disassembled the handle, a rod with paint is removed from it. His nose is cut off. The content needs to be removed. Alcohol is used for this. This procedure is done carefully, otherwise the dye will be on clothes, interior items, etc. The body and the rod are connected with a needle.
Using a spray gun
Next, you need to try the resulting product. First, water is drawn into the container. Next up is the paint. You need to blow hard into the bottle. The paint will come out through one end of the prepared mold.
To adjust the jet, you need to adjust the position of the rod and the body of the handle. The pressure of the jet depends only on the force with which the master blows into the bottle. This is how a homemade sprayer works. It is easy to assemble it with your own hands. However, the texture of the paint will not be thin and uniform. It will consist of individual drops.
This option is suitable for those surfaces for which a high degree of evenness is not important. As a result of this processing, an interesting texture is obtained. It consists of many drops. This allows you to create a certain visual effect. The quality of the work is influenced by the experience of the master. Therefore, before starting surface treatment, you need topractice.
Model improvements
Do-it-yourself spray gun for water or paint can be made according to the described scheme, but with some modifications. In this case, the device will be able to perform finer, more accurate work. To do this, you need to perform a number of improvements.
Another hole is made in the bottle cap. Another rod from another gel pen is inserted into it (it must be prepared in the same way as before). Only its diameter and length should be smaller. This is taken into account when choosing a pen. This action allows you to increase the pressure in the bottle. As a result, more paint can be blown out with less effort.
The second needle is inserted into the body of the pen. It connects to the second rod. Next, you can practice applying paint. The actions of the wizard will be the same. But now the coverage will be better. To adjust the jet, you need to move the rod that supplies the paint.
Advantages and disadvantages of the model
It is easy to make a spray gun for painting with your own hands according to the proposed scheme. Almost everyone can handle this task. The advantage of the model is the possibility of its modifications. If necessary, a hose of a compressor or a hand tool (for example, a bicycle tire pump) is connected to this structure. In this case, it will be easier to work.
The disadvantage of the model is its limited range of applications. The pattern that the paint forms may not suit the existing style of the interior or the look of the object. Therefore, before starting work, the tool musttest it on a training surface. It is also worth considering that this model is suitable for thick paint. It will be difficult to apply whitewash in this way.
If the container does not have a lid, it can be made from improvised means. If the paint is water-based, ordinary foam is suitable for this purpose. If the composition includes chemical dyes, you need to make a cork for the container from rubber or other similar material. It will not break down when exposed to solvent.
Aerosol can
There are several more options for how to make a do-it-yourself paint sprayer. A simple design can be made from a conventional aerosol can. It is suitable for water-based paint application.
To assemble such a spray bottle, you will need to prepare a bicycle tube, a plastic bottle, a regular can, for example, from deodorant, as well as a hand or foot pump. The second option is more convenient. It will be possible to work with a can with two hands.
The construction is assembled according to a certain scheme. With the help of such an airbrush, it will be possible to perform a high-quality application of liquid material to the surface. Spraying in this case will be more uniform than in the previous version. Yes, and it will be easier to work with this device. Air will be supplied to the cylinder using a pump. This ensures good atomization of the paint.
Assembly procedure
If you want to make a do-it-yourself spray gun for whitewashing with lime or water-based paint, a design option will dofrom a balloon. First you need to cut the nipple from the bike tube. Its lid has a diameter of approximately 3 mm. A hole is made in the bottle.
Next, you need to fix the nipple on the inner wall of the bottle. It will force air inside the tank. After that, the sprayer must be removed from the can. To do this, you need to cut the body of the container with a hacksaw for metal. The spray module with valve must match the diameter of the bottle neck.
The valve must be cold welded to the bottle cap. The connection must be tight. This is a prerequisite. After all, the system is under pressure. After the manipulations, the device is tested under a pressure of 3 atm. You should also try applying paint on the training surface.
Spray gun from a vacuum cleaner
There is another way to make a spray gun with your own hands. If you need to paint walls or ceilings, a manual spray gun will be quite tricky to apply. To process a large area, you will need a device with automated paint supply. In this case, a refrigerator compressor or (easier) an old vacuum cleaner is used.
Such structures spray water-based paint well. It is not suitable for powder dyes. It is also worth considering that only an old Soviet-era vacuum cleaner is suitable for such work. Their design was significantly different from modern models.
The hose of the old vacuum cleaner could be connected to both the inlet andoutlet pipe. This allowed the technique to work both for blowing and blowing. It is the second mode that will be required when creating an airbrush. If the owners still have a similar unit somewhere in the pantry, this will be an ideal option for painting walls and ceilings.
Creating an atomizer
Do-it-yourself paint spray gun is assembled from an old vacuum cleaner. In some cases, a new model that is no longer planned to be used for its intended purpose is also suitable for this. In such a vacuum cleaner, you will need to change the direction of the thrust. To do this, you need to change the poles on the terminals. They are adjacent to the stator and rotor.
After the unit starts working in the desired mode, you need to select a suitable container (bottle) for the paint. The neck of such a container should be wide. The cork should have a rectangular ledge. It will allow you to insert a tube from a gel pen here at a right angle. You can also use a dropper for this purpose.
Holes are made in the lid and tubes are inserted into them. One of them will provide paint supply, and the second - compressed air. You also need to make another hole in the cork. It is necessary in order for air to enter the bottle. When the volume of paint in the container decreases, a vacuum occurs in a tightly closed container. Another plug should connect the hose from the vacuum cleaner and the paint spray system.
Fridge compressor
You can assemble an atomizer with your own hands from a compressor left over from an old refrigerator. This unit will run quieter thanvacuum cleaner. When whitewashing ceilings with lime or water-based paint, such equipment will provide significant savings in materials.
It will be more difficult to assemble such an airbrush. It is necessary to choose a sufficiently large sealed container (receiver). It can be a canister, a fire extinguisher, a cylinder or other similar item.
You need to remove the compressor with the start relay. Copper tubes need to be sawn off with a hacksaw or a bite to eat with a special tool. Next, the system is connected to the network. It is necessary to pay attention to which tube the air is supplied. A gasoline filter from the car is attached to the structural element that sucks it in with a hose and sealant. This prevents dust from entering the gun.
Assembly continued
When assembling a spray gun with your own hands, you need to connect a tube to the receiver to inject air. For this, hoses of the appropriate size are also used. They are connected with a fitting and sealant. On the receiver you need to install a filter for diesel fuel. This will prevent moisture from the air from entering the system. The spray gun in this case works more efficiently.
On the board you need to fix both the receiver itself and the compressor. Next, you need to check how the system works. If everything is fine, you can get to work. During the verification process, it is also worth practicing working with such an aggregate.
It is worth considering that the compressor must be installed in the same position in which it worked in the refrigerator. If this is not done, the equipment simply will not work. Also, during prolonged use of suchsprayer, you need to periodically change the oil in the compressor. To do this, you need to find the third tube in the unit housing. If all actions are performed correctly, the device can be used to spray thick water-based paint, as well as whitewash or other types of materials.
Holder
You can make a holder for a spray gun. To do this, you need a board with a thickness of 10 mm. A square of 250 x 250 mm is cut out of plywood or wood. A hole in the form of a circle is cut in it with a jigsaw. It must match the paint tank of the unit. The handle of the pistol is inserted into the groove. It is cut from the edge of the plywood to the hole. The structure must be installed on a support of 3-4 legs.
Having considered the options for creating a spray gun with your own hands, you can design a suitable type of design. This will allow you to apply paint, whitewash quickly and efficiently.
