How to refill a spray can with paint. How to make a reusable spray paint can easily and cheaply

Spring has come. Many teenagers almost instantly had thoughts in their heads of going to the nearest abandoned site and drawing branded graffiti, for which they would need an incredible amount of spray paint.

Important: You should not abuse this type of activity, it is illegal, and the current legislation provides for administrative liability for such hooliganism.

However, many people will also need spray cans for quite acceptable purposes, for example, painting their new craft. However, the cost of one can is quite high, and if you need a lot of them, and perhaps even more different colors, the wallet of a creative person will be significantly emptied. In order to prevent this, you can make a homemade reusable can, which will significantly alleviate financial losses.

How to make a canister reusable using available materials?

In order to make such a tool, you need to follow a simple sequence:

Find an old used spray can. If there is no such thing nearby, you can simply purchase a new one, use it for its intended purpose, and then begin upgrading our tool.
To begin with, drill a small hole in the bottom of the now empty can. We must not forget that there is still some old coloring matter left in the can, which means it needs to be thoroughly rinsed with a solvent.
The next step is to hold the nipple in a drill and clear it from the chamber by tinning it.
Afterwards, you can safely install the nipple into our can. Next, you need to add a little water and then inflate the balloon. If bubbles do not form, everything is done correctly.

How to use it?

As a result of completing all of the above points, a new can will come out, which will not be thrown away after the first use, because it can always be refilled using a regular syringe. What is needed for this? You just need to buy a special paint and mix it with a solvent. This is necessary to ensure that the paint does not come out too thick or too thin. Such actions help regulate the density as the user needs it. Also, we must not forget about pumping air using a pump.

What are the savings? How much should you spend and how much can you save?

It's actually simple math at work here. One can of paint, holding about 400 ml, costs about 200 rubles. Buying paint separately will cost about 70 rubles per 1 liter, and 500 ml of solvent can be purchased for 40 rubles. It turns out that for 110 rubles we get at least a liter of paint, while in a store for 200 we buy only 400 ml. Using simple calculations, you can determine that for the same canister, made yourself, you will need to spend about 50 rubles, instead of 200. The savings are quite impressive, which is good news. However, this method also has a number of disadvantages, for example, pumping paint through a syringe or mixing it with a solvent yourself.

To a person without experience, it may seem that using a spray can is very simple. Indeed, a simple, everyday matter, what could be complicated about it? You need to press on the valve and after that the composition will immediately begin to spray - beautifully and evenly, over the surface on which it is needed.

Alas, in reality everything is completely different. Moreover, you need to carefully prepare for painting a particular surface with a spray can - this is also important.

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

Simply put, it’s worth talking in detail about how to spray paint correctly so that the result turns out great (this tool can have an impact on).

Why paint correctly

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

What can I say?:

Painting a car completely with a spray paint is quite possible. However, experts advise contacting a car service - the costs will be approximately comparable;
One more point: since there is a lot of work, it is not easy to maintain a decent level of quality and a beginner can make mistakes. It is better to let professionals perform such responsible work.

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

Little things to remember

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

For example, let’s consider working with machines, since these are the tasks that are most relevant today; spray cans are used for car repair everywhere.

Details:

It is known that automobile trains able to dry very quickly. As a rule, the result is ready within an hour. But the coloring itself must be done carefully and carefully - haste is simply unacceptable here;
In accordance with the instructions, you must first carry out painting work preparatory work, aimed at the room itself. They usually paint in boxes, garages, sometimes they work directly on outdoors- This is fine. The main thing is if you decide to work under open air, do this not on a sunny day, or in calm weather;
Lighting – important aspect spray painting. It must be good. Perfect option– uniform lighting work surface. Bright sun It’s not suitable for this, neither are the spotlights - let them be directed exactly where they need to be.

It's all about the glare - they will definitely interfere with the master and mislead him. The perfect solution– luminous flux that will be diffused. Fluorescent lamps are recommended for use.

How they work:

First, the room should be vacuumed. It is worth doing this work conscientiously, because the quality of the future result depends precisely on the thoroughness of the cleaning - it is much more pleasant to be clean;
There are some tricks: floors, for example, are usually moistened with water (but not too much 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;
It was already said earlier that work must be carried out step by step. That is, you need to apply the next layer of paint or primer only when the previous one has already dried. If in the box where spray painting is carried out, heat, a film may appear on the paint. Most often, there is still damp paint hidden under it - because of this, a shagreen effect occurs (there is such a possibility);
One more nuance: when asked how to properly spray paint, experienced people recommend dismantling the part to which the composition will be applied and working with it individually. If there is a car in the box, it should be protected with a cover or fenced off with a special screen to avoid unpleasant incidents;
The personal safety of the master is also an important aspect. Enamels and varnishes for cars are toxic and quite harmful to human health, which is no secret. Accordingly, before painting you should have goggles, a respirator, overalls and gloves on hand.

Painting different surfaces - a review 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 plastic elements of a car will be considered. The first step is to remove this product from the car.

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 of plastic and metal is often performed by different means(and they are not interchangeable).

And now in detail:

The area that is damaged is thoroughly cleaned - emery cloth will help with this. If you work with plastic, you can limit yourself to P220 grit. When the treatment is completed, the bumper is washed again, then dried and wiped special means– anti-silicone (you can choose something else, similar);
Any chips or scratches great depth It is customary to seal with specialized putty designed for plastic. However, if you don’t have anything like this at hand, you can be content with traditional car putty - this is what many people do today. The composition is prepared in certain proportions: 1 to 50. One part here is the hardener, 50 is the putty. All work is carried out with the utmost care, but you must act quickly. It’s just that the putty hardens within 20 minutes - you need to keep it up to this point;
The surface is cleaned again after the putty has dried - again used for this sandpaper. Of course, it is better to use here grinding wheel, but not everyone has it at hand. For convenience, it is recommended to fix the paper on a block. The main point of the work: the transition between the putty surface and original coating should be ideal, the border should not be determined by touch.

Now it's time to degrease the part that is being repaired. Wipe carefully, first wet wipe, after dry. It is worth using lint-free wipes;
Next, you need to start priming. The soil is chosen to be specialized - specifically for plastic products. In any department where car cosmetics are sold, you can buy an excellent quick-drying one-component composition, which comes in aerosol cans. Apply two layers of it to achieve the desired result;
When everything is dry, you need to apply developing powder to the defective area and sand again. However, this time everything is done wet. You should act carefully so that the primer is not erased - otherwise you will have to apply the primer again. The surface is treated with a matting film at the finishing stage;
Now they degrease again - and now comes the most interesting part: painting from a can. At least two or three layers are applied; the master must wait until the previous layer dries before starting on a new one. Finally, the bumper is varnished several times.

It is worth varnishing the entire bumper, 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 desired shade composition, correct. The color can also be selected according to the markings (which are on the can), but everything is not so simple. The point is that different manufacturers the color differs (often slightly). However, over time, the body coating may slightly change the initial shade. The ideal way solve the problem - just ask for help service center– here they are guaranteed to help you choose the right composition. In addition, using special equipment you can pump the necessary paint into a can. The cost of repairs in this situation will be slightly higher, but the tone is guaranteed to match;
Next, the car needs to be washed. For this they use warm water. Afterwards, the car is wiped down - anti-silicone and some kind of rags are used here. It is recommended to cover all areas that will not be painted with polyethylene or thick paper (for securing, masking tape is used, which is applied around the perimeter of the protected areas);
At the defective area, the rust (as well as the space around it) is thoroughly cleaned - sandpaper will help with this. Of course, after such treatment the gloss will be erased and the surface will take on a matte appearance. The master must now apply a special degreasing compound - and you can begin to putty (everything is almost the same as when processing plastic).

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

There is no need to cover everything at once - they are applied in several layers (each of which is thin), the directions must be alternated, otherwise peeling 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 make themselves known (or even everything will begin to crumble);
The surface that has been puttied needs to be cleaned - sandpaper is traditionally used for this. But when working with metal, you cannot 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 - it is absolutely impossible without this;
The area with the defect, as when working with plastic, is covered with a special primer. They do this several times. Afterwards grinding is carried out - for this purpose a matting composition is used. At the end, everything is wiped with an antistatic agent and degreasing is performed again;
Now it's time to spray paint. Before doing this, the container must be shaken thoroughly. It is best when the valve has a flat nozzle (rather than a round one). These valves (with a flat nozzle) are good because they are equipped with a narrowly directed spray pattern - this has a beneficial effect on the result.

It is not so important how you spray paint metal - from top to bottom or vice versa. The main thing is that the composition should be applied to the surface evenly; you should not linger in one place, because this may cause drips.

If you carefully read the instructions, you can find out the following: the distance from the valve to the surface should be approximately 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 at least three layers, then the varnish is applied in two layers.

About refilling a spray can with paint

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

The first step is to select the can itself for subsequent refilling. Solid containers are ideal for this. Just those containers that are not assembled in a factory (with welded seams, from different parts), especially if the pressure is created by a compressor, it is dangerous to use. Such a product can easily rupture;
When the container is selected, you need to remove the valve. Next, you need to take a simple medical syringe, large capacity. No needle needed. The composition must be drawn into the syringe;
The size of the balloon inlet and the syringe outlet diameter are almost identical. The function of an adapter can easily be performed by a flexible plastic tube (a product 10 mm long is sufficient);
The required composition is drawn into a syringe, then it is connected to the outlet of the cylinder through an adapter. All you have to do is press the valve and the liquid is pumped into the container - nothing complicated;
You can create pressure different ways. 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. It is also worth remembering about safety: it is recommended to put the cylinder in a tarpaulin cover;
Another product is already used as an adapter here. It can be obtained from the syringe needle cap. The open edge is fixed to the pump hose, a hole is made in the sealed one - this is what you need to press against the cylinder, and everything will definitely work out.

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

If the container previously contained paint of a different color, 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: painting with a spray can is easy, there is nothing difficult here.

The difficulty lies in competent preparation surfaces, is to create optimal working conditions.

The work can be reduced in cost if you use rechargeable cylinders. A video about this is recommended for viewing by everyone: both experienced masters and beginners.

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.

Don’t rush to throw away your deodorant can; you can refill it with another substance and even paint. To do this we will need a larger medical syringe, a vinyl tube and a small compressor or pump.

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

We prepare the syringe; to do this, remove the needle and put on a vinyl tube instead, cut it off, leaving 4mm uncovered. We fill the syringe with paint, remove the spray nozzle from the can and place the tip of the vinyl tube of the syringe onto the tube of the aerosol can.

We press the connected syringe with the can onto 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 pierce a hole in the closed end of the cap with an awl, but do not destroy the side at this end.

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

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

Filling paint into an aerosol can is one of the components that ensures the sale of the coloring composition for a fairly high price. If we take into account that spray painting is disproportionately more convenient, and is widely used in the automotive industry, when a person repairs a car with his own hands in order to save on car service, then high price– an extremely negative point.

A can usually doesn’t last long, it costs quite a lot, so there is a natural desire to save money by not paying the cost of new cans every time, and the injection process, which you can do yourself.

This is quite possible if you fill a can of paint with your own hands from a purchased large container with a coloring composition, which in this form is much cheaper. To do this you need to purchase one disposable good manufacturer, and carry out the process of converting a used aerosol container into a vessel into which paint can be pumped repeatedly.

Second possible variant– purchase special equipment for refilling aerosol cans, which is not sold everywhere and is quite expensive. The third is to refill it in the appropriate workshop where there is such equipment, but there it will be approximately half of the cost of the refilled paint, and they may give a small discount for several cans.

How to repurpose an existing container

To remake a disposable vessel so that you can fill it with paint yourself, you need to take an already used one, choosing a model with a good, hard bottom and a tube nozzle. Of course, the paint will not be refilled under such pressure as in factory conditions, but refilling can be done repeatedly, and you will pay practically nothing for it, except for the cost of the coloring composition. And this will save almost half the cost of the dispersed spraying process. To do this you will need:

used aerosol can;

a nipple that can be cut from an old bicycle tube;

large medical syringe;

pressure gauge (not necessarily new);

car or bicycle pump.

To make a reusable can of paint, these things, which can probably be found in the garage or at a disassembly site, are quite enough. To refill an aerosol can, remove the cap and spray nozzle, draw the paint into the syringe, and insert the syringe into the can all the way, with the safety valve pressed down.

You can also use deodorant containers by adding a few metal balls. Injection is carried out in this manner until the level of the composition reaches approximately 2/3 of the volume of the vessel. Then the bicycle nipple is inserted and the can is refilled compressed air.

On video: installation for refilling aerosol cans.

Necessary conditions for refueling

Aerosol cans are filled with compressed air to a pressure of approximately 3-5 atmospheres. At lower pressure, filled vessels do not spray paint; at higher pressure they can easily explode. That's what an old pressure gauge is for. After pumping the air, the nipple put on for filling aerosol cans is removed, and the cap with the sprayer is put in place.

The container with the pumped liquid and air is shaken, and the spray intensity is checked on any suitable surface. Many motorists refill spray cans at specially designated points to save time, and do not realize that there are no secrets in how to refill a spray can with paint, and you can save not only time, but also money.

How to pump paint into a can (2 videos)

An interesting solution for coating is paints produced in spray cans. With their help you can evenly paint the surface. Thanks to aerosol spraying, the consumption of paint and varnish material is not very large, and markings on the product help facilitate the selection of the required tone. You can even refill the paint into a spray can yourself. The presence of marking codes is very important when, for example, a car body is partially repaired or restored.

But such a factory-made form of release is much more expensive than conventional dyes, and the desired tone is among finished products It’s not always possible to choose. What to do in this case? You can fill the can with something you purchased or tinted with your own hands. the right paint yourself, or you can turn to the services of specialists, and then enjoy all the benefits of fine spraying.

Advantages of aerosol application of dyes

Usage paint and varnish materials, released in finished containers with a spray, provides a number of advantages:

Saving material. All the paint released from the can will fall directly onto the surface being painted, and will not remain on the roller, brush or other painting tool.
Quick preparation for use. This paint does not need to be diluted before use and poured into a container for convenient use. It is enough to shake the dye container for 5 seconds so that the balls in it ensure mixing of the solution, and you can spray the coating onto the surface.
Possibility of dosed use due to the difference in the force of pressing the sprayer. When painting small scratches and cracks, just lightly press the spray button.
The ability to carry out partial restoration repairs by spraying a coloring composition onto damaged areas. With the right color scheme, after drying the surface will appear evenly painted.
Even the most difficult to reach places can be easily painted.
No special painting skills are required; even an amateur can handle the job.
The remaining paint in the can does not require quick use; in such a container, it will retain its original qualities for a long time.
Convenient for storage and transportation: the container is sealed, dyes will not spill out of it and will not stain the floor.

In such containers, dyes of various compositions and qualities are produced; they can be used on wood, metal, glass, and concrete; apply for external or interior works. Selection desired color won't be difficult.

When is it necessary to fill the dye into the container?

This must be done in the following cases:

tinted paint remains, and it must be preserved for a long time;
color selection among finished aerosol products is impossible (for example, a complex color or such a dye simply does not exist).

You can pump paint into a spray bottle by contacting a specialized company, where they will quickly fill the required container using a vacuum unit. But such refilling is quite expensive, and if immediate use is intended, then you can pump the paint into the container yourself.

How to refill a cylinder yourself

Filling paint solutions into a spray can can easily be done with your own hands.

Of course, it will not provide such complete filling as with vacuum pumping with a special installation, but it is simple and cheap.

The cylinder can be used repeatedly.

Required tools:

An empty can of deodorant or paint. If a container is used after dyes, then you need to fill in a solution of the same quality (for example, after acrylics - acrylic, after alkyds - alkyd). Incorrect selection of paint and varnish components can lead to a “chemical conflict” that will affect the quality of the coating.
Paint for refilling. Any one will do - purchased in a store or tinted yourself with the necessary selection of shades.
A large medical syringe without a needle: with its help the paint will be pumped into the container. For more efficient squeezing safety valve you can put a broken needle on it.
Bicycle nipple (can be cut from a worn-out inner tube).
Pump (car or bicycle).
Pressure gauge.

Operating procedure:

Remove the cap and spray nozzle from the can.
Draw the coloring solution into the syringe, insert it into the container until it stops, pressing the safety valve.
Pour the dye into a container.
Repeat the filling procedure until the container is approximately 2/3 full.
If you used a deodorant container, you need to add 3-5 metal balls there. Balls from worn-out bicycle bearings are quite suitable for this purpose.
The remainder of the container must be filled with air under pressure, otherwise the sprayer will not work. To do this, insert the bicycle nipple tightly, squeezing the safety balloon valve.
Connect the pump to the nipple and, while pumping, create a pressure of up to 3-5 atmospheres. If you do less, you won’t get a full spray; if you do more, the container may not be able to withstand the load.
After inflating, remove the nipple and replace the cap with the sprayer.
Now you need to shake the can a little, stirring the coloring solution, and check its operation. For this purpose, release a small portion of the dispersed mixture onto an unnecessary board or other surface.

Application

With paint filled in this way you can:

paint a decorative composition;
evenly paint surfaces that have a complex configuration;
carry out cosmetic or complete renovation automobile body;
draw graffiti on walls or airbrush a car;
restore furniture and much more.

Self-filled dye, when creating the necessary pressure in the container, is evenly sprayed over the surface, ensuring material savings and quality of finishing.

The balloon form of release is convenient to use, ensures material savings and long-term preservation of the quality of residues unused during repair and decorative work.
