The tool for painting cars with your own hands
The spray gun is an indispensable tool for painting cars
The Sata 4000 HVLP spray gun is excellent for working with any paint coating because it applies the paint technologically and economically. Of course, 400 euros is not such a small amount, but when you try to paint with this spray gun, you will not feel sorry for this money.
The Sata 4000 (compared to its predecessor Sata 3000) is even easier to handle, turning the paint into a homogeneous spray mist. finer and more consistent spray pattern for a better spray pattern. The features of the Sata 4000 sprayer are as follows:
- nozzle: 1.3 millimeters;
- tank: 0,6 l;
- unique trigger design protects the needle packing from paint mist;
- Weighs 15% less than its predecessor;
- instant adjustment of the spray pattern;
- a new can mounting system (quick release);
- the needle packing has become self-sealing;
- Thanks to the improved design of the paint flow adjustment, it is easy to work even with gloves on;
- SATA 4000 HVLP is not only suitable for organic enamels, but also for water-borne enamels.
The packaging of such a gun can not help but please, because it includes the necessary tools for quick disassembly and assembly, a special cleaner, color identifiers and a set of filters for paint.
Spray gun for anti gravel coatings
Often used for gravitex. SATA HRS is the perfect spray gun for spraying high-viscosity materials. This tool requires a compressor at 8-10 atmospheres for accurate aiming. It has 3 types of gravitex feed (thin, medium, and thick) adjustable. But the most important thing is that it is a very durable paint sprayer, because it is created with all-metal casting technology.
The main working accessories of the painter
A number of additional procedures are carried out before and after the application of paint to the surface. These are a variety of preparatory and finishing jobs that require the use of appropriate products. That is why apart from enamels and lacquers, car painters use paint consumables, such as primers, fillers, polishing pastes.
After damage repainting is carried out on a leveled surface, prepared for the application of lacquer coating. Grouting does not always produce a perfectly smooth surface. Any remaining rough spots, scratches, and dents are smoothed out by applying filler.
Two-component and one-component types of fillers are on sale today. Deep dents are treated with two-component products that include a filler mixture and a hardener. the two components are thoroughly mixed before use, forming a thick and viscous substance.
One of the most necessary supplies in a workshop or a private garage for the final preparation of the car body. polishing paste. It can be used to quickly remove the occasional minor scratch from a surface, correct minor paint defects, achieve an attractive gloss or, conversely, a matte effect.
How to Make a Paint Gun by Yourself?
If you have ever been engaged in changing the color of your car, then you probably know what a useful tool the paint sprayer for painting cars, and it does not matter whether it is factory-made or made by your own hands. Its main function is the application of various paint, water and chalk or water and lime compositions to the surface, although it is often used for other tasks, such as watering houseplants.
In this article we will talk about popular ways to create such a sprayer with your own hands, which will help you to get a mobile, compact and lightweight device without significant material costs.
How to make a paint gun from a ballpoint pen
So, to make a paint gun from a ballpoint pen you need not so many tools. In particular, it is worth stocking up:
- A gel fountain pen;
- A paint casting container (a small bottle with a lid can do);
- Use a needle from a disposable syringe (it is better to have several, in case one breaks).
- First you need to disassemble the pen and remove the paste from it (it should be an empty tube through which air can freely flow).
- Then, you must cut off the tip of the lower part of the handle to make the hole enlarged.
- Now, having disassembled the rod, it is necessary to remove from it the rests of paste (alcohol is used for this purpose), and in the center of the cap of the prepared container to make a through hole of the same diameter as the rod.
- Perpendicularly to the hole for a rod, in the cap it is necessary to drill a hole for the body of the handle.
- In the final phase of assembly, the rod and the body are inserted into the bottle and connected by means of a needle, after which you can proceed to paint the desired surface.
How to make a spray gun from an aerosol can
Another, relatively simple homemade device for painting a car, is the spray gun, made from an aerosol can. It’s great for working with water-based paint, and all you need to build it is a plastic bottle, a bicycle camera, and an aerosol can (a used deodorant bottle works great). A bicycle pump also comes in handy.
- With a camera from a bicycle must be cut off the nipple with a cap (diameter 3 cm).
- Then, it is necessary to make a hole in the bottle.
- And glue the nipple to the inside of the bottle (it will perform the function of forcing the air mass).
- Now, using a metal hacksaw, saw out of the prepared can spray module with valve (the size of the aerosol can must match the diameter of the cork from a plastic bottle).
- The next step. connection of the valve and the plug by means of cold welding, and it is important to create a completely airtight connection, as the structure will work under pressure.
- It remains only to test the device pressure, not more than 3 atmospheres.
Get the desired effect can be achieved in different ways: using a special film, electroplating or painting under the chrome. Of course, each method has both pluses and minuses, but now this is not the point.
Paint sprayer with their own hands using a hose from a vacuum cleaner
You can also make a paint sprayer with a hose from a vacuum cleaner, and this option will be more reliable than the previous ones. In addition, such a paint sprayer is a versatile device that can be used both for painting a car and for whitewashing the ceilings in the house. Of course, not every vacuum cleaner will be a worthy substitute for a full-fledged compressor (not all models have a blow-out mode), but if you find a suitable option, it will make an excellent compressor, since these vacuum cleaners have high pressure.
Despite the fact that in itself such devices are not designed for painting cars or whitewashing water-based paint, when connected to a normal working sprayer situation can be changed.
- Preparation of necessary materials and tools (you need to find a glass or plastic bottle with a whole screw neck diameter not less than 20-25 mm; aluminum or copper tube, a length of 20 cm and a diameter of 4 mm and bakelite handle, which will be used as a handle).
- Direct assembly of the structure. At this stage it is necessary to bend a 20-centimeter copper or aluminum tube and fix the nozzle for the vacuum cleaner hose on its lower end. The upper end is equipped with a nozzle made of a brass rod.
- Next, a groove is cut into which the prepared handle is inserted. It is best to use a tube of copper, which has a diameter of 2 mm. It will pump out the paint, so its length must be sufficient. The upper edge of the tube must be deburred so that it becomes cone shaped. The tube itself is inserted into the socket of the plug connector.
- It is also necessary to create a bracket with a hole that will fit the dimensions of the socket. The best material for this is a sheet of steel.
- All the prepared parts are assembled in such a way that the end of the suction tube is at the level of the nozzle.
- It remains only to test the work of the assembled homemade paint sprayer on a test surface. If the pressure is too high or too low, it will be necessary to adjust the clamping force of the tube.

Spray gun from the refrigeration compressor
Homemade electric paint sprayer, created with a refrigeration compressor, is the result of the most complex and time-consuming process, although the tool itself turns out to be very reliable and multifunctional. To make such a paint sprayer at home, you will need parts from an old refrigerator and some other elements. In general, the list of all the necessary tools and materials is as follows:
- a compressor from a refrigerator;
- A convenient container for the paint material;
- A set of hoses (one 40 cm and two 10 cm);
- clamps with a diameter of 20 mm;
- steel wire;
- car filter;
- part of a wooden board;
Finished with the preparations, prepare to perform a number of sequential actions.
First of all, it is necessary to fix the compressor on a wooden base. Inspect it carefully. The standard unit has three copper tubes, one of which is sealed. To determine which piece you need, connect the compressor to the mains and by trial and error, try to determine from which hole is the discharge of air. this is the main outlet. Accordingly, the spigot with the open hole is the inlet. Hoses of the appropriate diameter are attached to both ends of the tube, the joints of which are fixed with clamps.
The sealed tube, from the very beginning is intended for compressor lubrication, therefore, if the motor works without any problems, it is better not to touch it.
It is necessary to drill two holes in the receiver and fix two hoses into them: the longer one connects to the inlet of the compressor, and the shorter one to the outlet. To control the pumped air, the pressure gauge must be fixed.
The receiver is attached to the compressor base. One hose connects both devices, and the second nipple is connected to the filter (the main task of this element is to clean the air from various impurities). The final step is to connect the paint sprayer.
Taking into account the fact that the airbrush turns out quite bulky, you can attach handy wheels to the wooden base.
Features of homemade paint sprayer application
Let’s assume that you have already chosen what to replace the factory paint sprayer at home, however, there remains another equally important question: “How to properly use such a tool?”. Of course, in this case has its own peculiarities. For example, when spraying paint does not need to stay long in one place, as the layer of paint material will get too thick. To paint perfectly evenly, the spray gun must be moved in a circular motion, with the paint jet directed strictly perpendicular to the part to be painted (otherwise the paint material consumption will considerably increase).
Each successive coat must be applied after the previous one has dried completely. In addition, the success of the subsequent work depends largely on the quality of preparation of the painted surface and on the selected parts to create a “home” paint sprayer.
Despite the fact that the process of making the described tool is quite labor-intensive, and often takes a long time, but if you follow the instructions carefully, you are sure to get a good and inexpensive paint sprayer.
Equipment for painting cars
In order to update the body of your car, should acquire not only the paint, but also special equipment for painting cars, supplies for it, additional accessories. Modern industry produces a huge number of devices in order to facilitate and accelerate the repair and renovation of the vehicle.
Service stations have the opportunity to use in the work of professional equipment for painting works: powerful compressors, sprayers of various types, pneumatic tools, cameras for drying and much more. You can paint your car on your own, but it should be thoroughly prepared.
Correctly spray painting individual areas
Spray-painting. it is an attempt to eliminate minor flaws of the paint coating, however, it can be useful for painting discs with their own hands, bumpers, mirrors, decorative elements and other small things. With a can, by the way, you can give the car a peculiar look when applying a temporary coating, like liquid rubber, PlastiDip, camouflage paint, chrome or gold paint. But the latter two are mostly used in poor neighborhoods in New York City to the melodic overtones of rap, so it’s worth thinking hard before using car gold. There are plenty of protective coatings in cans. SUVs and pickups like to cover with brutal Raptor, which is applied by spraying, as well as by roller or brush, if it is a fender or the bottom.
You must be aware that local spray painting almost never leads to stunning results, because the transition from old paint to new to hide quite difficult, and to avoid them, you need to perfectly pick up the paint, which is also difficult, and then carefully polish and buff the transition. But this type of painting teaches you a lot.
In the photo painting with a spray paint can, with which you can eliminate small flaws in the paint coating
Here are the tools you can’t do without for this version of partial painting:
- Spray can(s) with paint.
- Soft rags, lots of them.
- Degreasing liquid. Depending on the composition of the paint.
- Painting tape, polyethylene tape, old Argumenty i Fakty newspapers.
To restore the damaged coating will be suitable for any acrylic paint, just look at the spray can. You need a wide spray pattern for a good result, and the only way to get it is with a slotted opening. There are spray cans with metallic or chameleon paint, but it is difficult to vouch for the success of the event. If we are talking about body sections, then the quality paint should be applied at a pressure of 4-5 atmospheres. No spray cans can do that.
Painting is done only after careful degreasing of the surface. Garage floor should be washed and moisturized, drafts eliminated, insects destroyed. After this simple preparation, you can start laying the first layer. It is not applied glossy, but with a slight shagreening, so that the following layers adhere well to the surface. After applying the first base coat, you need to wait for its complete drying, only after that you can apply subsequent ones with drying and make a break of 15 minutes. Each subsequent coat must be fatter than the previous one, but you must be careful not to leave any streaks. The most dangerous is the last layer. It’s easiest to tear off if you overthink the thickness. Then the whole work must begin again. Painting a car with their own hands. not the kind of work in which you need to hurry.
Spray paint is the lowest quality among car paints, so it is incredibly difficult to polish it, and sometimes even impossible, if it’s also cheap. So neatness is a requirement for the spray painter. After painting the damaged area, there will inevitably be a transition from the old paint to the new. Removing it is much more difficult than splashing paint on the surface. It can be put out with a solvent, and then the place can be polished after it has dried completely.
Rectifying the car body by your own efforts. Methodology for building the work.
Damage to the bodywork is something that can happen to anyone. Did not fit while parking, got in an accident, or just snagged a fence, the visual effect will be instant. Dents. very clearly visible and such flaws need to be corrected immediately. In this article, we will briefly review the main points of the straightening process itself, as well as make a list of the tools you need.
Basic concepts and procedure
The first thing you should learn is that it is not so easy to make auto body alignment with your own hands, it requires a certain knowledge and skills of the performer and you need to be very careful when doing it. After all, you can not only not fix the defect, but to make things worse.
In essence, straightening is the alignment of damaged areas of the body. You should approach the situation soberly, if the detail is badly damaged, it may be cheaper to just replace it. If the defect is small, then you can get down to work.
At the moment it is most often done with a pneumatic hammer. But if you don’t have this tool, you can do everything manually. Of hand tools you will need a hammer, a mallet. Alignment is done gradually, some masters even heat the metal a little. But if you’re a beginner, don’t overheat it so it doesn’t melt.
Depending on the size of the dents, the technique will be different. So, with a large dent, you have to do the straightening work starting from the edges, slowly approaching the middle. If the damage is small, it is better to start from the middle, and then tighten the edges.
A set of tools you need for straightening
Depending on the severity of the damage to the body, you will need different tools. Here I will only write about a few of the most common solutions. But the presence of modern equipment is only welcome, especially if it can be borrowed from acquaintances.
So, here is that small stock of means at hand of the one who is planning to do straightening of his car:
- hammer with a flat beater. Use it to level out flat areas of the body.
- a hammer with a sharp beater.
- hammer with a convex beater. For convex surface types.
- hammer iron. Used to smooth out the machined surface.
- Notched Hammer. For treating elongated surfaces.
- Alignment files;
- the spotter, which is used to spot-weld the bodywork.
- anvils or support elements. the one used as a support surface on the back side of the surface to be straightened. Especially when working with hammers. These surfaces take some of the load.
- Alignment hooks. They are used to squeeze out dents.
The list doesn’t end there. Each case requires an additional tool kit.
Vacuum straightening of the body without painting
Only 15 years ago, this method was just a science fiction. Everything is done by hand. First leveling, then sanding, priming and painting. With the help of special devices that have vacuum suction cups. this method has become a reality.
The whole procedure consists of the following. First you fix the suction cups in the area of the dent and then with a simple movement of the hand you pull the metal. This method does not require additional painting and it is easy to apply it all over the body.
On the plus side is that you do not need to dismantle the part from the inside, external treatment is enough. It is worth noting that this method does not eliminate the dent 100%, but visually corrects the situation.
use this method when there are cracks on the bodywork, even if small. By applying it, you will bend the surface, and you will need to fix it all.
Vacuum straightening is most effective on large, flat dents.
Pulling out the dent with a grip
This is the second, more time-consuming type of straightening. Use it where there is extensive damage to the body.
The whole point of the technology is as follows, you screw in the center of the dent with a screwdriver, and then use an inertia hammer to slowly pull out the bend until the treated surface returns to its former state.
Self-tapping potholes are putty filled and painted.
Tapping the dented body
This is the most time consuming process. You have to pull the body apart where the damage was done. Next, mark the area of the dent on the workpiece. Tapping on the inside of the flaw, on the reverse side there must be a supporting surface, such as an anvil.
In some cases, you can heat the metal a little to make it more flexible.
Homemade spray guns. possible or not?
Painting a car is a complicated and expensive task. It is necessary to take into account the quality of paint application, it is necessary to use the most technologically advanced equipment. Self-made paint sprayer has become a certain dream of many car owners who want to save money on painting services. If you go to a professional shop, painting your car will cost several times what you expect. In this case, most motorists begin to watch video lessons and prepare to work with their own hands.
To perform the necessary work at home is difficult, but nothing is impossible. The design of homemade devices for painting cars has become one of the most popular topics on all forums on this topic. It is interesting that many people manage to collect their hands even paint sprayer, which performs quite well household tasks. Let us warn you that to perform quality work and make a good car painting with self-made tools is extremely difficult. For most people without experience this will be impossible.
Tools for painting
Looking at the list of tools, painting may require:
- portable spotlight;
- paint mask;
- spray gun;
- polishing machine;
- Drill and nozzles;
- construction hair dryer.
These tools will help to effectively, qualitatively, and most importantly, in a short time to carry out restoration work on the painting of the car. Each of them has its purpose and is used at a certain stage. In addition, they may be needed to repair the car in the future.
Technology of painting the car with their own hands in step-by-step photos
Car painting with their own hands, if you follow the whole technological process in principle does not differ from the painting at the station of technical service. Is the lack of a paint booth, the role of which serves as a garage.
An indispensable condition for quality painting besides purchase of repairing materials is also possession of special equipment, well, and at least the modest skills of working with your own hands.
The technology of car painting can be divided into 5 main stages:
- Washing and cleaning the body.
- Removal and cleaning of rust.
- Matting, puttying and sanding.
- Priming and sanding.
- Car painting.
Depending on the quality of the item. possibly need a second priming. And of course the intermediate stages will be pasting (masking) of the elements of the body not subject to painting.
Below is a step by step guide with photos. so, let’s go.
1 Wash the body first detergents, then, should be washed off all the bitumen impurities and other dirt that was not washed away with water white spirit or not “evil” solvent, such as 650-ym.
2 Next, you should remove all stickers, icons and decals from the body elements which will be subject to painting. Use a hair dryer to remove the stickers, it is easier to use a heated one. Rinse off the glue residue with a solvent or a special rubber-like nozzle on a drill.
3 Remove corrosion, but not as in the photo “angle grinder” mashing disc, and a special vinyl nozzle on a drill or use the technology that is described in this article. After that you should matte the abrasive sandpaper all places subject to spackle. It is most convenient to do it with an orbital sanding machine, and if you don’t have one, you can do it with your hands.
4 Degreased all cleaned and mat all places can proceed to puttying. How to do it correctly and technologically, you can read here and here.
5 Start sanding the putty places. It is better for this purpose to use a special planer, which is set abrasive paper with an abrasive grain of the required size. If you do not have a planer, buy a “rubbing board” as in the photo below or use a flat wooden bar.
6 All problematic places of the car body are puttied and grinded, it is possible to start priming the repair zones. But first it is necessary to paste up with a masking tape and paper the details, which are not primed.
On the “bare” metal is applied 2 thin layers of phosphate (acid) primer and then all the putty areas overlapped two-component acrylic primer in 2-3 layers. At the same time with this action we fill the risks from the coarse abrasive.
7 Let the primer dry and you can proceed to the primary sanding. You can also use a special planer or the same “rubbing board” for this purpose. The grit of the abrasive sandpaper at this stage is already applied more finely. For more detail, about grinding technologies and rules read the articles from the section “Painting a car.
8 At this stage it is necessary to “slow down” a lot, blow the car with compressed air and with a good illumination to inspect the results of the work DURINGLY. If there are any risks, steps and other irregularities in the repair areas, which may not be visible to the eye, but can be felt with the palm, it is mandatory to repeat the priming with two-component acrylic primer.
If everything is OK, then again using the orbitalik or hands, as in the photo below, should “knock down” the risk of the previous grinding even finer abrasive. So, for example, for metallic painting this size. Р500.
9 We have cut the riser on primed places, now we need to prepare the rest of the surface for painting. And for this you need scotch-Brait (metallic gray) and matting paste. The technology of the process is very simple. Put the paste on the bodywork and moisten the scotch-Brite with water and begin to mat the surface very carefully in circular motions.
10 everything is ready, we are getting ready to paint, of course, with our own hands. We remove all the stickers (adhesive tape and paper) and with the help of compressed air from the compressor (the word carefully applies in the obligatory order to all technological operations in the preparation and painting) we blow out all the slots and openings, where the dust and water could get from sanding and matting.
11 Prepare the room (garage) for dustless painting, unless of course you paint in a spray booth. And again paste the body, but already under a paint.
12 Next step is to wipe the car with clean, lint-free cloths and silicone compound until no streaks remain.
13 Everything is ready, proceed to paint the car. We dilute the paint, prepare the spray gun, put on the paint suit. Here is an example of metallic painting (base and varnish).
At first it is necessary to apply the base (pigment) on places, covered with the primer, and then following the technology of work with the spray gun to cover with two layers of pigment all the painted elements.
14 wash the spray gun, dilute the varnish. Observing intervals between layers of drying, we put a couple of layers of lacquer on the pigment. dry. The painting of the car is finished.
15 The last step is the gluing and assembly of attachments (headlights, lights), as well as badges and stickers.
That’s how simple, in fifteen steps, as in the comic strip I showed the step-by-step technology of how you can paint a car with your hands. Of course, everything is much more complicated and there are a lot of nuances with which you need to deal. But for a general understanding of car painting technology I think it is quite suitable.
Whether after reading this you want to repeat the process in your garage or entrust this rather “dusty and dirty” business to professionals is up to you to decide. If you still decide to try, you are welcome! The entire site is to help you. read, try your hand. And remember, if you don’t try, you’ll never know how you did it.
