How to fill an aerosol can with paint. We make an aerosol can with our own hands

Today we will teach you how to make an aerosol can with your own hands from improvised means. This process is not as laborious as it might seem at first glance.

So, from the tools you will need: a clerical knife, a drill and drill bits, a saw and a bicycle pump. As for the materials for manufacturing, these are: a bicycle inner tube, rubber-based glue, an empty plastic bottle, an empty can and paint.

Well, let's get started?

Step 1.

First you need to release the remaining pressure from an empty can. This will protect you from its possible explosion. This can be done by releasing all the air from it. After that, you need to saw off the tip of the can and get its base, as well as a glass ball.

Step 2

Next, we cut the inflation tube from the bike tube and glue it close to the base of the plastic bottle. And yes, don't forget to drill a small hole where you stick this straw! Rubber-based glue is just perfect for this purpose.

Step 3

Now we need to make a nozzle. To do this, we drill a hole in the bottle cap suitable for the tip of the can with a straw, which we received by completing the first step. To fix it, glue also does not interfere.

Step 4

It's time to pour the paint. To do this, you can use a homemade paper funnel. IMPORTANT! You need to mix oil paint with oil, and acrylic with acrylic. Mixing oil paint with acrylic is not worth it!

Step 5

And now our spray can needs pressure. For this we use a bicycle pump.

So, if you did everything right, then with this simple invention you can create at least something like this:

To a person without experience, it may seem that using a spray can for staining is very simple. Indeed, a simple, ordinary matter, what could be complex in it. It is necessary to press on the valve and after that the composition will immediately begin to be sprayed - beautifully and evenly, on the surface on which it is necessary.

Alas, the reality is quite different. Moreover, you need to carefully prepare for painting this or that surface with a spray can - this is also important.

If you do otherwise, the resulting layer may lie poorly (or not at all), or the paint will peel off very quickly. The result of such work: money wasted, a surface that was spoiled.

Simply put, it’s worth talking in detail about how to spray paint correctly so that the result is great (this tool can affect).

Why paint the right way

If you need to paint a bench, a stool, some kind of children's toy or other not very large thing, there are no particular problems. But the situation changes dramatically when you want to apply paint to a car / bicycle, some kind of large structure.

What can be said here:

Painting a car with a balloon is completely realistic. However, experts advise contacting a car service - the costs will be approximately comparable;
One more thing: since there is a lot of work, it is not easy to maintain a decent level of quality, and a beginner can make mistakes. Let professionals do this responsible job.

Spray painting is an ideal option in a situation where some kind of fragmentary repair is needed (for example, if you need to restore the aesthetic appearance of the bumper or carefully decorate scratches of serious depth).

Little things to remember

To put it bluntly, the process of staining with a balloon is not so difficult - there will not be any special problems here. Another thing to consider: prepare the surface correctly. It is worth acting step by step, systematically, only with this approach you can achieve an ideal result.

For example, consider working with cars, since it is precisely such tasks that are the most relevant today, spray cans are used for automotive repairs everywhere.

in detail:

It is known that automotive compounds are able to dry very quickly. As a rule, the result is ready in an hour. But the staining itself must be done carefully and carefully - rushing here is simply unacceptable;
In accordance with the instructions, it is first necessary to carry out preparatory work for the painting work, aimed at the room itself. They usually paint in boxes, garages, sometimes they work right in the open air - this is normal. The main thing, if you decide to work in the open air, do it not on a sunny day, but also in calm weather;
Lighting is an important aspect of spray painting. It must be good. The ideal option is uniform illumination of the work surface. The bright sun is not suitable for this, as are spotlights - let them be directed exactly where they need to be.

It's all about the glare - they will definitely interfere with the master, they will mislead him. The ideal solution is a luminous flux that will be diffused. Fluorescent lamps are recommended.

How do they work:

First, the room should be vacuumed. Doing this work is worth conscience, because the quality of the future result depends precisely on the thoroughness of cleaning - it is much more pleasant to be clean;
There are tricks: floors, for example, are usually moistened with water (but not too plentifully so that there are no puddles). When water is applied, there will be much less dust;
It is better to refrain from using fans - they will only complicate the work. Operating temperature - from 15 to 25 degrees. It is these indicators that are ideal if you need to paint with a spray can;
Earlier it was said that the work must be carried out in a step-by-step mode. That is, it is necessary to apply the next layer of paint or primer only when the previous one has already dried out. If the temperature in the box where spray painting is carried out is high, a film may appear on the paint. Under it, most often still raw paint is hidden - because of this, the effect of shagreen appears (there is such a possibility);
Another nuance: when asked how to properly paint from a spray can, experienced people recommend dismantling the part on which the composition will be applied, working with it individually. If there is a car in the box, it should be protected with a cover or protected with a special screen - in order to avoid unpleasant incidents;
The personal safety of the master is also an important aspect. Enamels and varnishes for cars are toxic, quite harmful to human health, which is no secret. Accordingly, goggles, a respirator, overalls and gloves should be at hand before staining.

Painting different surfaces - an overview of technologies

If we talk about painting technologies, then in the automotive field it is customary to distinguish two basic areas: repair of plastic surfaces (torpedo, bumper, etc.), as well as repair of a metal body (fragmentary).

About working with plastic

Using the example of a car bumper, the process of painting the plastic elements of a car will be considered. First of all, this product should be dismantled from the machine.

An interesting fact: experts recommend degreasing the surface after any procedure performed. The composition for such work is selected depending on what material the base is made of. Degreasing plastic and metal is often performed by different means (and they are not interchangeable).

And now in detail:

The place that is damaged is carefully cleaned - an emery cloth will help with this. If working with plastic, you can limit yourself to grit P220. When the treatment is done, the bumper is washed again, then dried and wiped with a special agent - anti-silicone (you can choose something else, similar);
It is customary to repair any chips, as well as scratches of great depth, with a specialized putty designed for plastic. However, if there is nothing similar at hand, you can be content with traditional automotive putty - as many do today. The composition is prepared in certain proportions: 1 to 50. One part here is a hardener, 50 is putty. All work is done with the utmost care, but you must act quickly. It’s just that the putty hardens within 20 minutes - you have to meet up to this point;
The surface is cleaned again after the putty has dried - again, sandpaper is used for this. Of course, it is better to use a grinding wheel here, but not everyone has it at hand. For convenience, paper is advised to be fixed on a bar. The main point of work: the transition between the puttied surface and the original coating should be perfect, the border should not be determined by touch.

Now it's time to degrease the fragment that is being repaired. Wipe gently, first with a damp cloth, then dry. It is worth using lint-free wipes;
Next, you need to take on the primer. The soil is chosen specialized - specifically for plastic products. In any department that sells auto cosmetics, you can buy an excellent quick-drying one-component composition that comes in aerosol cans. In two layers they are covered to achieve the desired result;
When everything is dry, it is necessary to apply developing powder to the defective place and polish it again. However, this time everything is done in the wet. It is worth acting carefully so that the primer does not turn out to be erased - otherwise you will have to apply the primer again. The surface is treated with a matting film at the finishing stage;
Now they are degreasing again - and now, the most interesting thing: painting from a cylinder. At least two or three layers are applied, the master must definitely wait until the previous layer dries, only then take on a new one. At the end, the bumper is varnished several times.

It is worth varnishing the entire bumper in general, not just the damaged area - so that the transition is not visible visually.

How to paint metal elements

Details:

First of all, you should understand: the master needs to choose the right shade of the composition, the right one. The color can also be selected according to the marking (which is available on the can), but everything is not so simple here. The fact is that different manufacturers have different colors (often slightly). At the same time, over time, the body coating may slightly change the initial shade. The ideal way to solve the problem is to simply contact the service center for help - they are guaranteed to help you choose the right composition. In addition, on special equipment, you can upload the necessary paint into the can. The cost of repairs in this situation will be slightly higher, but the tone is guaranteed to match;
Next, the car must be washed. To do this, use warm water. After the car is wiped - anti-silicone and some kind of rag are used here. It is recommended to cover all areas that will not be painted with polyethylene or thick paper (for fixing, masking tape is used, which is applied around the perimeter of the protected areas);
In a defective place, the rust (as well as the space around it) is carefully cleaned - sandpaper will help with this. Of course, after such processing, the gloss will be erased and the surface will become matte. The master must now go through a special degreasing compound - and you can already start puttying (everything is almost the same as when processing plastic).

What if the body damage is too significant? In this case, it is necessary to use putty, which contains fiberglass. Such material will not only help level the defect, but also reinforce the surface as reliably as possible.

It is not necessary to close everything at once - they are applied in several layers (each of which is thin), while the directions must be alternated, otherwise delamination may occur;
It is not recommended to add too much hardener to the putty. This composition will dry quickly, but will lose elasticity. That is - even a slight deformation and cracks will let you know about themselves (or even everything will begin to crumble);
The surface that has been putty needs to be cleaned - sandpaper is traditionally chosen for this. But when working with metal, you can not do without various abrasives. There is a use for both coarse grain and grinding paste - any master should know about this. Of course, degreasing is performed after each of the procedures - without this it is impossible;
The place with a defect, as well as when working with plastic, is covered with a special primer. They do this several times. After grinding is carried out - for this, a matting composition is used. In the end, everything is wiped with an antistatic agent and degreasing is performed again;
It's time to spray paint. Shake the bottle thoroughly before doing this. It is best when the valve has a flat nozzle (rather than a round one). These valves (with a flat nozzle) are good in that they are equipped with a narrowly directed spray jet - this has a positive effect on the result.

It is not so important how to paint metal with a can - from top to bottom or vice versa. The main thing is different - the composition should be applied to the surface evenly, you should not linger in one place, because streaks may appear.

If you carefully read the instructions, you can find out the following: the distance from the valve to the surface should be about 20-35 cm. This is quite a lot - any specialist will confirm. Each master chooses this interval individually (on average, 15 cm is enough). The paint is applied in three layers at least, then the varnish is applied in two layers.

About refilling a can of paint

Many are interested in how to make a spray can of paint. Someone is concerned about this topic, not so much for reasons of economy, but because the compositions from different containers often differ from each other. In addition, it is also possible to refill varnish, primer, and not just paint, which is very practical.

The first step is to choose the can itself for subsequent refueling. Solid-cast containers are ideal for this. It’s just that the container that is not assembled at the factory (with welded seams, from different parts), especially if the pressure will be created by the compressor, is dangerous to use. Such a product can easily break;
When the container is selected, it is necessary to remove the valve. Next, you need to take a simple medical syringe, large capacity. The needle is not needed. The composition must be dialed into the syringe;
The balloon inlet size and the syringe outlet diameter are almost identical. The function of the adapter is easily performed by a flexible plastic tube (a product 10 mm long is enough);
The desired composition is drawn into a syringe, then it is connected to the outlet of the cylinder through an adapter. It remains only to press the valve and the liquid is pumped into the container - nothing complicated;
There are many ways to create pressure. The most practical is to use a factory compressor, which is also equipped with a pressure gauge. But if there is no such product, you can adapt a bicycle pump or limit yourself to the same syringe. Safety is also worth remembering: it is recommended to put the balloon in a tarpaulin cover;
As an adapter, another product is already being used here. It can be obtained from the cap of the syringe needle. An open edge is fixed on the pump hose, a hole is made in the sealed one - it is this that needs to be pressed against the cylinder, and everything will definitely work out.

Before refilling the spray can with paint, you should make sure that the substance being poured has the same composition, the same base as the composition that was there before. A simple example: nothing good will come of it if car paint is poured into deodorant (the solvent in this case will corrode all gaskets without any problems.

In the case when there was paint of a different color in the cylinder before, you can do this: first pump in the solvent. This will help get rid of any residue from the container.

conclusions:

It's time to take stock. Based on the above material, it is clear to anyone: it is easy to paint with a spray can, there is nothing difficult here.

The difficulty lies in the competent preparation of the surface, in creating optimal conditions for work.

Work can be reduced by using rechargeable cylinders. A video about this is recommended for viewing by everyone: both experienced craftsmen and novice specialists.

The main thing is to follow the advice, then the result will be of high quality and there will be no difficulties in the process.

Do not rush to throw away the deodorant can, it can be refilled with another substance and even paint. To do this, we need a larger medical syringe, a vinyl tube and a small compressor or pump.

If you need to fill the paint in a spray can, then you need to dilute it to a liquid state. Depending on how much the deodorant bottle is designed for, and it is usually 150 milliliters, then you can fill it with no more than 2/3 of the volume of the deodorant canister, no more than 100 milliliters.

We prepare the syringe, for this we remove the needle and put on a vinyl tube instead of it, cut it off leaving 4mm undressed. We draw the paint into the syringe, remove the sprayer from the can and put the tip of the vinyl tube of the syringe on the tube of the aerosol can.

We press the connected syringe, with a can, on the valve and at the same time inject paint into it, after you pour 100 milliliters of paint into the can, take the safety cap from the medical needle, one side is thicker, insert it into the compressor or pump hose, securing it with a clamp or twisted wire, and on the closed end of the cap we pierce a hole with an awl, but do not destroy the rim on this end.

We wrap the balloon in a strong bag of cloth or place it in a strong pipe for safety. We turn on the compressor and rest the closed end of the cap, with a hole, on the cylinder valve (the rim on the cap that I wrote about above will help us with this). When inflating, press on the valve tube. Air fills the balloon with air, creating pressure in it and gurgling will be heard in it, this air passing through the paint fills the balloon, creating pressure.

At the same time, keep an eye on the pressure gauge, and although at the factory the cylinder is pumped up to 4 kg / cm2, it is better to roll up no more than 2.5 kg / cm2 so as not to risk it, especially since you can pump up the cylinder at any time. The cylinder is ready for reuse.

A spray bottle is an indispensable thing for a household. Painting a car, making repairs, whitewashing trees is much easier if you have a spray bottle at hand. In pneumatic it splits into tiny particles under the influence of air. The electric spray gun works without the use of air - the coloring agent is thrown out with force by the pressure that the electric motor creates. If there was no sprayer at home, then you can make an airbrush yourself, while simple models require only 15-20 minutes of manufacturing time.
To make a spray gun with your own hands, you need a spray gun and a little time

Spray gun manufacturing

You can assemble a spray gun for paint from improvised means. Depending on the model you choose, you will need a plastic bottle or ballpoint pen, a vacuum cleaner or an empty deodorant can. For various purposes, a different version of the atomizer is selected. Homemade work which uses its own breath, suitable for painting small surfaces. To assemble a quality one with your own hands, you will have to use more complex models. Let's start the manufacture of sprayers with simple designs, gradually complicating the process.

Option number 1: making a spray gun from a ballpoint pen

A manual spray gun from a regular pen is used for painting small parts. The quality of the atomization depends on the accuracy of the assembly. For this model you will need:

Ballpoint pen and refill
Container for paint - a bottle or glass jar with a wide neck is suitable
wine cork
Syringe
Glue, alcohol, toothpick

To assemble the spray gun with your own hands, you need to disassemble the ballpoint pen and cut off the narrowed end of the body - this will increase the diameter of the hole. Paste is blown out of the rod with a syringe, then the tube is washed with alcohol. The nozzle of the syringe for this is heated and expanded with a toothpick.

A corner is cut out of a wine cork - about a quarter. Holes of the same diameter as the rod are drilled in the center of the base of the cork and in the lid of the bottle. Perpendicular to this hole, a hole is drilled horizontally in the thin wall of the cork for the handle body. The empty stem and pen body are inserted into the holes and pulled out perpendicularly with minimal clearance.

The rod is inserted into the lid of the bottle, on which the cork is glued. The small spray gun is ready - now you just need to blow into the body of the pen to start spraying paint. The whole car cannot be repainted with such a device, but spot painting will be quick and economical.

“Mini spray guns for painting cars can be made using a wooden block, textolite, polystyrene foam and even plasticine instead of a wine cork, if nothing at all is at hand”

Option number 2: making a spray gun with a gun

To make it more convenient to hold the spray gun, a gun is made. You can use regular plywood. The tube with a diameter of 4 mm is bent L-shaped. One of its ends is connected to a vacuum cleaner, on the other, a thread is made for a turned one. In one piece of plywood in the form of a pistol, a recess is made for the tube, the second remains flat. This is how the pen is going.

A tube with a diameter of 2 mm is inserted into a glass container through an adapter. You can take a plug brass socket. A holder for a tank is cut out of sheet steel - a bracket with ears for attaching to a gun and a hole for the neck of the jar. Another homemade spray gun for painting a car is ready.

Option number 3: making a spray bottle from a plastic bottle

This manual spray gun for cars is made from a plastic bottle with the ability to pressurize air with a pump. It is necessary to prepare some parts and tools in advance:

0.5 liter plastic bottle or more
Automotive nipple
Old paint spray can
Adhesive, auto sealant
Pump

You can make an airbrush at home from these materials as follows:

Cut off the top of the spray can so that only the paint sprayer and the tube from it remain.
Poke a hole in the bottle cap
At a distance of 3 cm from the cork, burn a hole for the car nipple and insert it from the inside. Seal the hole with sealant
Pour the strained paint, screw on the spray cap

Do-it-yourself airbrush for painting a car is ready. It remains only to connect it to the pump and pump air - it is enough to make 10 movements. When using a hand sprayer, it is necessary to strain the paint as thoroughly as possible so that the sprayer does not clog.

Option number 4: making a spray bottle from an aerosol can

There is nothing complicated in making a spray gun from a spray can with your own hands. The most important thing is to follow safety precautions.

Method A

You will need:

Seamless deodorant bottle with protruding sprayer pin
Syringe
Vinyl tube with a diameter of the nozzle of a syringe

A few simple manipulations will help you make your own spray can of paint:

Remove the plastic top from the deodorant
Attach the vinyl tube to the syringe tip.
Cut the vinyl so that it is half put on the atomizer sticking out of the can - the valve should freely enter inside
Filling the paint into the can is made at the rate of not more than 1/2 of the volume of the aerosol
Without removing the vinyl tube from the syringe, draw paint with it
Place the can on a hard surface, put the free end of the vinyl on the valve, press it in with the nozzle of the syringe and pour in the liquid - this is how you can fill the can with paint the fastest, repeating the procedure several times

Now you need to create pressure inside the can, that is, pump air into it.

Before pumping air, be sure to place the balloon in a bag made of dense fabric - in case of a rupture, all the contents will remain in the bag, and your hands will not be injured.

No more than 3 atmospheres are pumped into the can. As an adapter, a protective tip from the syringe needle is used. By pressing the valve into the can, you will open the air from the compressor. If the process goes well, then the paint inside will begin to gurgle. In extreme cases, you can pump air with a syringe, but this will take a long time.

It remains only to put on the button from the valve. To keep your hands clean during work, you can purchase a special nozzle - a gun for a spray can of paint.

Method B

If the canister that is selected for the sprayer does not have a protruding valve, then you can fill the canister with paint with your own hands as follows. This will require:

Needle for inflating the ball
Fountain pen refill, cleaned of paste (3 mm diameter)
Big syringe
Paint can without sprayer pin
Pump or compressor

To refill the aerosol can with your own hands, cut off 2 cm from the rod, put it on a needle to pump up the ball - a device will be required to inject air into the balloon. Place a 3 cm piece of the rod on the syringe. Take the button from the can, remove the rubber seal from it, which is in the place of spraying. Put the button back on the can, insert the syringe with the pumped paint into the hole, press the button and drive the paint into the can. Insert a needle with an adapter from the rod into the same hole, press the button, pump in air. Paint volume - 50%, air pressure - no more than 3 atmospheres.

Method C - making a refillable can

To make a do-it-yourself reusable spray gun from a can with the ability to quickly pump air, you will need the following tools and materials:

Paint can
Automotive nipple
Soldering iron, hammer, piece of wood

The essence of this design is to insert a nipple for pumping air into the bottom of the can. You can make this type of paint sprayer at home as follows:

Clean the nipple from the rubber
Tin the bottom of the can in the center and the nipple
Drill a hole in the bottom with a diameter of a nipple
Carefully drive the nipple into the hole through the piece of wood so as not to damage the edge, solder it
Pour cleaning solvent into the bottle, place it in a tight fabric bag, pump air through the nipple - no more than 3 atmospheres and test the sprayer

This is how a reusable spray can for paint is made, which is used for applying coloring compositions.

Option number 5: making a sprayer with a compressor

It is very difficult to blow into the tube from under the handle for a long time to paint a car part. It is better to make an electric spray gun with your own hands with automatic air supply. For its manufacture, a vacuum cleaner or a compressor from an old refrigerator is suitable.

Method A - using a vacuum cleaner

If a Soviet vacuum cleaner remains on the farm, then it already has the function of blowing air. You can make a spray gun with your own hands from a vacuum cleaner like this:

Remove the filters from the vacuum cleaner, thoroughly clean it of dust
Wrap the connections with tape to reduce air leakage, which means to make the pressure constant
Connect the blow hose to the spray gun

If the vacuum cleaner does not have a blowing function, then you can get it without touching the inside of the device. To do this, take a dense plastic garbage bag the size of a vacuum cleaner, find another hose. You can make a spray gun with a compressor as follows:

Take out the dust box
Put a plastic bag on the vacuum cleaner and tightly tape the edges of the bag around the place where the hose comes out.
Make a small hole in the opposite corner, insert the second hose into it, tightly wrap the junction with tape
Make a hole for the wire, wrap it with tape

In such a vacuum cleaner, the native hose sucks in air, and the additional one blows it out.

Method B - using a refrigerator compressor

Since the operation of the compressor is intermittent, a receiver will be required. It will absorb pressure drops. You can make it from:

Empty fire extinguisher with a volume of 5 liters
Empty gas bottle
car wheel
Two pipes that simultaneously serve as a stand for the compressor

With the help of a compressor from the refrigerator, you can make a high-quality airbrush

Each of these receivers equalizes the air pressure and supplies it evenly to the gun. Consider how to make a receiver from a car wheel:

Get a stamped tubeless wheel
Install an extra nipple in it
Connect compressor through nipple with nipple
Make a hose branch to the sprayer through the nipple without a nipple

For painting a car with a compressor from the refrigerator and a receiver, it will help to paint individual parts of the car.

Accessories

When making an airbrush and working with it, safety precautions must be observed. For example, a respirator can be made by hand. The dispenser stand is also very handy.

Making a respirator

To make a respirator at home, you will need the following materials:

Large plastic bottle with a flat bottom
Plastic tube (5-6 cm) that can be put on the bottle neck
A stopper that can be used to plug a tube from the inside
Cotton wool, gauze
Activated charcoal - 4 tablets
Hot glue, scissors, lighter

Manufacturing steps:

Cut off a piece of 13-15 cm from the bottom of the bottle, drill many holes in the bottom, make a cutout for the nose on the cut. Burn the edges with a lighter. Try on the design to be comfortable
Cut off the neck and two centimeters of the bottle from the top - this will be the lid for the bottom. Spread it in diameter with glue and put it on the bottom with holes
Insert cotton through the neck to close the holes
Smear the cork with glue, insert it into the tube. When the glue dries, drill more holes in the cork
Put folded gauze on the inside, sprinkle crushed 2 tablets of coal, cover with cotton. Pour 2 more charcoal tablets, cover with folded gauze. Try how to breathe
Put the tube with the filter on the neck of the bottle, glue
Wrap all joints with electrical tape, make fixing elastic bands

Making a holder for an airbrush

The simplest do-it-yourself stand for an airbrush is made from a sheet of plywood 10 mm thick. A square of 25 * 25 cm is cut out of it, in which a circle is cut out with a diameter slightly smaller than that of a container for paint. A gun is inserted into the groove sawn from the edge of the workpiece to the hole. The stand is installed on the legs. Their height is selected so that there is room for the hose.

WATCH THE VIDEO INSTRUCTIONS

Paint sprayers are made at home from various improvised means. The use of such tools is associated with a risk to health, so they must be made and used in compliance with safety regulations. The quality of the result when painting often depends on the accuracy of the assembly of a particular model.

The use of paint in aerosol cans is one of the options for painting the surface. At the same time, material consumption is significantly reduced. The required color is selected according to the marking on the product. This is important if the paint is not applied to the entire surface, but only to some part of it. Filling paint in an aerosol can can be done independently.

Advantages of using dye from a balloon

LKM from an aerosol can is valued for a number of its qualities:

The dye is used sparingly. All sprayed material falls on the surface to be painted. Since the painting tool is not involved, the paint residues do not remain on the brush or roller.
Spraying begins immediately after shaking the balloon to stir the dye with balls that are inside it. It is enough to do this for 5 seconds. Other types of paints are prepared for application more carefully: mixed until a homogeneous mass, diluted with solvents to the desired consistency, poured into a convenient container. Saves time for coloring.
Controlling the use of the dose is easy: by pressing the spray button.
Dye in cylinders is carried out restorative repair of part of the surface. The place of staining after the paint dries does not stand out against the general background.
The balloon allows you to paint the most inaccessible places. The paint lays down evenly over the entire surface.
A beginner in the painting business can do the job, no special skills are needed.
There is no need to purchase special equipment for painting the surface and refilling the cylinder.
If the material is not used to the end, then you should not worry about its safety. In the bottle, it retains all the qualities from the manufacturer
The container is airtight, which allows you to store and transport the dye without worrying that it will spill out.
It becomes possible to carry out repairs without a car service at the time of difficulties with finances.
The cylinders are filled with paint of different composition and intended for painting different surfaces: wood, plastic, glass, concrete. It is applied both to the outer surface and to the inner part.

Conditions for filling the cylinder with dye

Injection of paint into aerosol cans is carried out if the following conditions are met:

It is known that paint residues after painting will not be needed for a long time and they must be stored.
It is difficult to choose the paint color used among ready-made dyes in cylinders. Therefore, it is refueled for safety in case of restoration work.

If the dye in the cylinder will not be used at the moment, then it is better to fill it with specialized equipment at the company. If the painting is urgent, then you can fill the container yourself.

Elements of the cylinder for refilling the dye

Algorithm for filling the container with dye

Injection of cylinders on professional equipment is beneficial in terms of capacity filling, but is not available due to the high price. Self-filling aerosol cans with paint is justified by its low costs and ease of operation. Although the container is not filled to the maximum volume.

The aerosol container can be used more than once.

Before filling the can with paint, tools are prepared:

A container is being prepared: an empty deodorant, from under the dye. A container of paint of one type is pumped with paint of the same type: acrylic after acrylic, alkyd after alkyd. Otherwise, a "chemical conflict" may occur. The quality of the paint coating will suffer from this.
A dye of the desired shade, purchased ready-made or tinted with your own hands, can be refueled.
The dye is injected with a large volume medical syringe. If an additional broken needle is used, then the release of the safety valve will be more effective.
A nipple taken from an old bicycle inner tube is used.
For bike or car pump chamber inflation.
Manometer measuring pressure.

Before filling the paint into the spray can with your own hands, the cap and sprayer are removed from the container. The remaining steps are performed in strict sequence:

The syringe is filled with dye.
The cylinder fuse is pressed with a needle on the syringe, and the syringe is inserted into the container until it stops.
The paint is pumped into the balloon. HER number corresponds to a certain shade. You can choose the desired color by fan. Colors for tinting are most often chosen from RAL, NCS, Pantone catalogs. Mixing base colors allows you to get the desired shade.
Actions are performed until 2/3 of the container is full. So, for example, a 520 ml balloon is pumped into 400 ml. This capacity is enough for painting 1.5 m 2 if the paint is applied in two layers.
To stir the dye, 5 balls are added to the balloon. Bicycle bearing balls will do.

Useful video on the topic:

In order to spray, pressurized air is added to the tank to be filled:

The release of the safety valve is carried out by the nipple of the bicycle. It is inserted into the bottle.
A bicycle pump is connected to the nipple. Air is pumped up to a pressure of 5 atmospheres. Low pressure does not provide high-quality atomization. If the indicator is greater, then the capacity is broken.
The nipple is removed and the spray button is installed in its place.

The can is ready to use. It is shaken, the paint is mixed and spray control is carried out. A small dose of dye is applied to an unnecessary surface.

Application area

Aerosol dye is used:

For coloring decor in the interior.
For application to the surface of a structure of a complex unusual configuration.
For restoring the repair of a car body part.
Used for applying graffiti on wall surfaces.
For airbrushing on cars.
Used in restoration.

Method for applying dye from an aerosol can

In a room with room temperature, paintwork materials lie on the surface better. At the same time, the room is ventilated, respirators are put on the face.

The surface to be painted is washed and dried.
Degreasing of the place of painting is carried out.
Construction tape creates the boundaries of the place of spraying. Areas of the surface that will not be painted are covered with newspapers or a covering film.
If the surface is leveled, then putty is used. On scratches, it is applied across. Aligning the applied putty, the hand moves along the line of scratches. At a temperature of 25 ° C, the treated surface dries for half an hour.
Hard fiberglass putty is sanded with sandpaper in the form of a bar with a grain of 60-240; for soft putty, grain 180-320 is used. In this state, it is left for 24 hours.
The next step is to apply a primer. The primer is applied in several layers. Between them, drying time is 10 minutes. When the priming is completed and the surface is dry, the surface is treated with sandpaper with a grain of 500, and finally - 1500. For metal, the primer is a protection against corrosion phenomena.
The resulting surface is degreased before painting.
You can start painting. Shake the container with the dye. It is applied at an angle of 90 about with respect to the surface. The spray can is located at a distance of 30 cm. Paintwork is applied in 3 layers. Allow 15 minutes between coats. Complete drying of the enamel occurs after 25 minutes. The material is applied evenly, without smudges.
To strengthen the coating, sometimes the surface is varnished in the same way as the dye. After 24 hours, the varnish dries. Polishing is carried out after a few days.

Paintwork from an aerosol container tolerates direct exposure to sunlight. Has a high degree of abrasion. Lacquer on the surface gives it strength and shine.
