How to paint metal from a spray can

The car wing most often suffers from careless actions of the driver. Careless parking, sharp branches, stones and other unpleasant surprises leave scratches, dents and chips on this part of the body. They not only spoil the appearance of the car, but also cause corrosion. However, you can easily fix your own work and restore the ideal smoothness of the body yourself. To do this, it is enough to know the methodology for carrying out such work and select materials of proven quality. Let's figure out how to paint a wing - quickly, efficiently and with a professional result.

Methodology for painting the wing

Preparatory work

— All work on painting a car can only be carried out in a clean indoor area - without dirt, dust and drafts. The ideal option is a spray booth. But an ordinary garage will also do, in which you first need to do a good cleaning. Do not forget that the final result of painting will depend on carefully carried out preparatory work!

— After this, the car body will need to be thoroughly washed and dried, and the area we will be working with will also need to be degreased. To do this, we use Chamäleon degreaser.

— Then we isolate the wing from the rest of the body using masking paper and Chamäleon masking tape. Thus, neighboring elements will be protected from splashes of paint and varnish during our work. After carrying out the preparatory work, we begin to study how to paint the wing, having first sanded and putty the surface.

(The stages of painting a wing are very similar to the stages of painting a bumper, so for clarity we attach our video)

Surface grinding

— The damaged surface must be treated with a coarse abrasive. To do this, take Indasa abrasive paper with a grain size of P120–P180 and begin sanding. This procedure can be carried out manually or using a grinding machine. During this stage, layers of old varnish and paint are removed, pockets of corrosion are removed, and the surface is leveled.

— After using abrasives, the surface of the wing must be thoroughly cleaned of dust. Then we treat the work area with Chamäleon degreaser. It will remove all unwanted substances from the coating, such as grease, silicone or Teflon. This will ensure optimal adhesion to the applied coatings, in addition, silicone craters will not appear during painting. How to paint a car fender if sanding alone is not enough and there are still defects on the surface?

Repairing damage

- In this case, you can’t do without putty. To do this, use a special spatula and universal ultra-light putty Chamäleon. It comes complete with a hardener and is ideal for filling cavities subject to heavy vibration. The putty is elastic and easy to sand, so no special skills are required to work with it.

— After the putty has dried, the surface is sanded using a coarse abrasive. Then you need to go over the coating with a softer abrasive with a grain size of P320–P500, paying special attention to the edges of the putty area. The surface must be perfectly flat and smooth both to the eye and to the touch.

Application of primer

Now you can start preparing the wing for painting. How to paint a wing correctly?

— First of all, the thoroughly sanded surface is treated with Chamäleon degreaser.

- Then you can start applying primer. Excellent results are obtained using standard Motip acrylic primer. It will prepare the surface for further coating with any type of paint and protect it from rust.

— It is necessary to apply 2-3 layers of primer, allowing each of them to dry for 30 minutes. The product should be sprayed from a distance of 25–30 cm to avoid smudges.

— After 2 hours, the primer will dry completely, after which the surface is sanded again using a soft abrasive P800. Now you can apply paint.

Applying varnish with a spray can

Varnish is applied to paints with a metallic effect. Can also be applied over regular paint to add extra shine and protection. It is applied 2-3 times. Before varnishing, the painted part must dry “stick-like”, that is, not stick when touched. The varnish in the can must be shaken for 1-3 minutes before painting. It is not advisable to spray it under the scorching sun. Otherwise you won't get a good shine. The varnish will dry within 24 hours at a temperature of about 20 degrees Celsius. At lower temperatures, the drying time will naturally increase.

You need to varnish at a longer distance. It is important that the torch is as wide as possible, but at the same time the varnish does not reach dry, but spreads normally over the surface, forming an even film. If you spray close, it will create streaks that will be noticeable once it dries.

If the painted surface has no defects, then it can be varnished after 10 minutes, without preliminary sanding. If the paint is to be varnished, it does not have to be glossy. The main thing is to apply it evenly. The final shine will be provided by varnish. If the painted coating turns out to have defects or inclusions of dust, then, after drying, it must be treated with p1000 sanding paper, then degreased and varnished.

Surface painting

— When asked whether it is possible to paint the wing of a car with a spray can, experts give an affirmative answer. Motip acrylic enamel is ideal for painting the wing in this way. It has excellent performance characteristics - it is easy to apply, adheres well to the surface and forms a stable and durable coating.

— To get an excellent result, you need to choose the right paint color. This can be done using a matching catalog or a color fan. Experts can also help in this difficult task - you will need to give the serial number of the body color and, perhaps, bring its small painted part.

— Before working with aerosol paint, shake the can thoroughly for several minutes. The enamel is sprayed onto the wing from a distance of 30 cm. After applying the first developing layer, the surface is inspected and felt again. If any unevenness remains, we sand it again. It is better to apply several thin layers, allowing each to dry for 20-30 minutes.

— The final stage will be to consolidate the result using Motip acrylic varnish. Apply 2 layers, allowing each to dry. Now we know how to paint a car fender - correctly and with excellent results.

If you strictly follow painting technology and use high-quality materials, you will be satisfied with the result. A freshly painted wing will delight the eye with a radiant shine. Read our tips and get to work quickly!

In general, the thought tormented me for a long time: is it really possible to tint a car with a spray can, and even with high quality? You can, of course, go to a service center, they will take money, they will make the car professionally, good or bad... But we, as you know, are not looking for easy ways, and we would like to gain experience and understanding of the issue. In general, I got the idea to conduct an experiment, paint a body element from a cylinder. It’s a useful skill, times are different and may well come in handy.

Technology: how to paint a car with an aerosol can at home without much effort?

If, upon inspection of the coating, it is discovered that the damage to the paint layer has reached the primer, or, moreover, the metal, then local touch-up cannot be avoided. It is worth noting the fact that paintwork repairs in these cases should be carried out as quickly as possible. The corrosion process goes almost unnoticed until the defect appears in a larger volume, forming a rust spot.

Preparing materials

Car enthusiasts who are interested in the question of how to paint a car themselves from a spray can should understand that the absence of the need for a compressor and a spray gun does not mean that only paint is needed for the job. Some components may not be needed, but it is still more convenient to have them on hand:

Sandpaper.
Degreaser, anti-silicone.
Putty and primer.
Aerosol with paint of the required color.
A container of polymer varnish.
PET film or newspapers.

You can replace antisilicone with alcohol-containing components. Don't forget about a respirator and protective clothing.

Body preparation

Using detergents, thoroughly wash the car body and let it dry. Next, we begin to work with the damaged area:

Degrease the surface using two napkins, soak one in solvent and wipe the entire area of the planned work. Second, wipe the area dry.
If there is rust, remove with sandpaper or chemical converters.
Limit the work area with masking tape and PET film or paper.
Treat the area with a primer; you can use the mixture in an aerosol can.
Let the primer dry for 25-30 minutes and fill the defective area.
After the putty has dried (20-30 minutes), sand it with sandpaper P350 - P400 until the body geometry is restored. Final processing is performed with abrasive P600 - P1000.
In places where the old varnish has been transitioned, the borders should be matted with P1200 sandpaper.
Degrease the repair surface using two napkins.

Car enthusiasts who already know how to spray paint their own car at home are advised to use a flat wooden block to secure the sandpaper.

Important! The preparation of the area for painting should cover a fairly large area relative to the repair area in order to subsequently polish the transition space.

Some nuances

The process of completely painting a car is more or less clear to most car enthusiasts. Partial car painting should take into account the spray area, it should not exceed the pre-treated area. It is necessary to ensure that the sprayed paint lies exactly along the border of the matte surface. There are a few more important points:

An aerosol can of paint or primer should be shaken for 2-3 minutes before use.
Preliminarily do a test painting on any unnecessary part.
The work must be carried out in a clean and ventilated room, where the air temperature is not lower than 20°C.
To optimize the drying process, you can use a hair dryer.

Advantages and disadvantages of the method

If the paintwork is only slightly damaged, many people try to avoid an expensive painting procedure.

In addition, this procedure can be carried out on your own by purchasing the appropriate cans of paint. It is important to carry out the procedure in the appropriate room and in compliance with all technologies.

Before that, you can evaluate all the advantages of this method:

To carry out such painting, no special skills or preparation are required;
using a spray can you can carry out high-quality repairs;
any surfaces are covered, hard-to-reach places and bends are much easier to paint; no additional components in the form of a roller, spray gun, etc. are required during the work;
if you have no experience in painting, you will be able to apply an even layer of paint;
to apply an even layer you do not need to work with a roller or brushes;
Spray painting will cost less than other means; this service is available to many motorists.

However, it is necessary to realize that all painting methods have their own nuances and disadvantages.

Spray painting is no exception to this issue, so be prepared for the following disadvantages:

there are no detailed instructions on the rams for painting;
Sometimes you come across cylinders of poor quality, so before applying to a car, test on another surface;
Sometimes the declared shade and the real one may differ, so you should immediately purchase the required amount.

Select the color scheme in accordance with the labeling, but if you are still not sure of your choice, then you should consult with the experts in their field.

He will be able to carry out tinting using special equipment.

If the depth of the chip or scratch is insignificant, then it is not necessary to resort to painting; you can polish it.

If primer or metal is visible in the damaged area, then the work will be more serious and eliminating the defect will take longer, as will painting the damaged part of the body.

Spray painting a car is a step-by-step procedure that is ideal for doing it yourself, which allows you to save money at the same time.

This method is suitable for working with a small area of damage, but if the problems are serious, then contacting a service station cannot be avoided. All work will be carried out there in a special box.

Drying speed of different types of aerosols

The drying speed of layers of primer and a mixture with pigments from a spray can is influenced by the following factors: the material being processed, the type and composition of the aerosol, the conditions of its storage and application (temperature, humidity), the number of layers.

Aerosol mixtures adhere perfectly to the area being painted; they cover metals, plastics, wood, stones, clay, glass, and plastic products. Compositions from spray cans dry quickly and are resistant to color loss, which is why they are popular among consumers.

The drying speed of aerosol coatings depends on the absorbency of the material. Processing and painting of objects should be done outdoors or in a well-ventilated area at an air temperature of 18-25°C and humidity up to 60%. These conditions are optimal for uniform coverage and natural drying.

If desired, varnish is applied to the paint layer. In this case, the protective properties of the dye are increased, a decorative effect appears, but the product takes longer to dry.

Acrylic sprays

Drying time for acrylic composition ranges from 40 minutes to 3 hours. If the filler contains more acrylic resin, drying occurs faster. When diluting the suspension with water, longer drying will occur. A porous surface absorbs acrylic faster than a smooth one. A sudden increase in temperature during drying (when heated with a hairdryer) can cause the acrylic mixture to peel off.

Alkyd-based aerosols

Alkyd mixtures have increased resistance to weathering, are elastic and durable. The drying speed of the “dust free” layer is 10-15 minutes.

Nitrocellulose enamels

Natural drying of alkyd mixtures and nitrocellulose compositions occurs at an ambient temperature of more than 22°C and humidity not exceeding 80%. With a multi-layer coating, the drying time for alkyd and nitro-enamel spraying is:

first layer - 20-25 minutes;
second layer - 6-7 hours;
third layer - 24 hours.

If polishing is necessary, the last paint layer is dried for 7 days.

Preparatory procedures, how to paint correctly

If you decide to carry out all the repair work on your own, then you should do everything as soon as possible. Once you discover damage, do not delay the process, as the problem may get worse.

Once the scratch reaches the metal, the oxidation process begins, leading to rust and corrosion. Because of these defects, more serious work will be required.

Before painting, the car is cleaned using conventional detergents. You need to wait until the surface is dry and then degrease it.

For this, special wipes and solvent are used. After saturating one napkin with it, wipe the surface dry with the second. To ensure greater comfort, you need to remove the part that will be worked on.

All other areas of the body that cannot be painted are covered with protective film and masking tape.

To prevent painting defects from appearing, a special chamber is needed; the room must be completely clean of dust and other contaminants. Lights, like devices, should be directed toward the work surface to avoid glare.

Work should not be carried out outdoors, as exposure to sunlight will negatively affect the result. At high temperatures outside, only the first layer is subject to drying out; it will take longer to wait for complete drying.

Therefore, before applying a new layer, wait until the previous one dries.

Before spraying the can, you should shake it well. Try not to go overboard and cover up the rest of the components.

If you are not sure of the result, then you can try your hand at an old part that you have.

Don't forget to follow the existing instructions and stock up on the following tools:

paint,
sandpaper of different levels,
putty and primer,
antisilicon,
polyethylene,
masking tape,
elements for protection.

When doing all the work yourself, be sure to consider hand protection; use a rubber or silicone spatula so as not to cause unnecessary damage to the surface.

The work of the aerosol begins only after the primer has been applied, dried and polished.

About refilling a spray can with paint

You can fill the can with paint yourself - this will reduce the cost of work

Many people are interested in how to make a can of spray paint. Some people are concerned about this topic not so much because of economic considerations, 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. It’s just that containers that are not assembled in a factory (with welded seams, from different parts), especially if the pressure will be created by a compressor, are 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;
Pressure can be created in 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.

The paint is distributed evenly - this is the most important thing

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 (the solvent in this case will easily corrode all the gaskets.

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.

A spray can for painting cars is what you need

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 proper preparation of the surface, in creating optimal conditions for work.

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.

Instructions for spray painting a car

The dyeing process is divided into a certain number of stages. At the first stage, preparatory work is carried out, which includes cleaning the body, degreasing work, and the use of anti-silicone.

At the next stage, you need to decide on the shade. Having previously checked the body marking instructions, a specialized store will help you choose the required option.

To prevent an error, colorize the body. Specialized equipment and software will evaluate the level of color fading and other factors.

It is worth noting that you will have to spend a lot of money on the procedure. In addition, paint options such as “metallic” or “chameleon” cost much more, because these shades are the most popular.

If there is already rust on the body, then you need to get rid of it, in this case you will need sandpaper, which will turn the surface matte.

After degreasing, we begin the putty process. If the defects are more serious, then you should use putty with windshield washer.

Do not overdo it with a layer, because it may peel off. Layers are applied gradually until the surface is completely leveled.
