Painting cars yourself is a responsible procedure that requires compliance with a number of conditions. A specialized camera for painting a car with your own hands - this option is chosen by many car enthusiasts today. Purchasing such an object will not be cheap, so some people prefer to independently provide what a do-it-yourself paint booth requires - drawings, materials, assembly.

Painting a car in this way has a number of serious advantages over using a spray gun in your own garage. Due to the tightness, you don’t have to worry about foreign particles of dust and dirt getting onto the painted surface.

In addition, the design eliminates the occurrence of unwanted air turbulence, due to which the enamel will not adhere to the surface properly, causing streaks, pimples and other defects to form.

DIY car painting

Do-it-yourself painting is profitable, but you will have to work hard to build it. With a competent approach and a conscientious attitude to work, you will be able to build a car painting booth yourself, which will help you avoid serious financial expenses and organize everything to your liking. Below we will look at how to make a spray booth with your own hands, and what steps are needed for this.\

What is a paint booth

The spray-drying booth is often used for painting work on cars and trucks. A special feature of the chamber is the presence of a special ventilation system and temperature control.

So that when painting, no small particles can get onto the paint layer. And also during drying, the necessary temperature conditions are created for the process to proceed correctly.

The powder paint polymerization chamber is distinguished by a special system for influencing the layer so that the adhesion strength of the composition is high.

Thus, the painting chamber is the place where the required conditions are created for applying and drying the paint and varnish material. Depending on the type, the arrangement of the room will differ.

Creating box lighting

It is best to equip a car painting booth with ceiling and wall lights evenly distributed throughout the room. It is also recommended to install several additional lighting fixtures on the back wall of the box.

For high-quality car painting, it is important that lighting devices do not contribute to the appearance of a flickering effect. For spray booths, the most convenient are long lamps mounted in a checkerboard pattern vertically. You can also equip the room with fluorescent lighting fixtures.

Advantages and functional features of the paint box

A car painting booth has a number of advantages over working in a regular garage. Due to the special arrangement, the possibility of dust and other contaminants getting onto the base after applying paint is eliminated, which is very important when covering the surface of a car.

There is also the possibility of creating a homemade camera. The process is not so complicated, if you do not violate the technology and take into account fire safety requirements, the result will be of a high level.

Due to the special arrangement, the possibility of dust and other contaminants getting onto the base after applying paint is eliminated.

Budget for building a car painting booth

If we consider the total budget required to build a full-fledged chamber, then about half of the investment should go to ventilation and heating systems, as well as insulation of the chamber. At least, this is approximately the ratio in factory painting booths. 30% of the budget will be spent on the power frame of the camera, even if it is equipped in a ready-made room, in a garage, hangar or box. Air filtration will take up at least 10% of the budget and 10-12% will go to lighting.

Do not overestimate the percentage of savings. Practice shows that thoughtless saving and working at random in any case is reflected in the result. Therefore, large investments are inevitable. They will be less than when buying a ready-made camera, the prices of which we will also touch upon.

Varieties

The equipped room can be done in different ways; the requirements for the arrangement depend on what they intend to paint. This could be a car, furniture, or other parts. For example, there is a chamber for powder painting. Therefore, you need to understand the types of cameras in order to choose the appropriate option.

For furniture

Furniture factories often use a special painting chamber, where wood undergoes all stages of coloring. This is how the material is prepared, painted and dried. There are different types of premises:

• Dry type;
• With water curtain;
• Excessive pressure.

With water curtain

A water curtain spray booth, like other spray booths, helps remove harmful solvents from the air that evaporate when paint is sprayed. This type provides three levels of air purification:

• Frontal water curtain;
• Internal air purification;
• Dry filtration.

Made from polyethylene

Special polyethylene is used; it is distinguished by its ability to magnetize so that dust particles are retained on its surface. This way you can avoid them settling on the paint layer. The matte film is stretched onto the walls; usually its effect is sufficient to paint 10-12 cars.

Air filtration and distribution

In a proper paint booth, there should be a continuous, complete renewal of air. Therefore, it is more logical to place the hood at the bottom and the supply fan at the top. It is incorrect to place the air outlet openings only above the painting area, however, the use of a correctly oriented supply plenum, the principle of use of which is shown in this drawing, will allow you to better manage the space.

An adjustable gas burner can be used to heat the air, which is connected during the drying stage. The heating element is located after the filter and fan, sometimes outside the pipe. In any case, the design of the paint room must provide for reliable insulation of the heater from explosive gases, so the air through the heater must move strictly in one direction, and through the attic space (pipes, plenums) at such a speed as to prevent reverse movement. When the fan is turned off, the heater must stop operating immediately. The placement of the filter over the main area of ​​the ceiling assumes a uniform distribution of air over the area, but with a weak fan it may simply not be enough - preliminary calculation is important to determine the area of ​​the grilles (plenums) and their location without the formation of turbulence zones.

The incoming air is purified by several filters, with a coarse filter located before the fan, and a fine filter directly at the boundary of the box. Cotton filters are often used as the latter, which are sheet (roll) material placed on top of the ventilation grille. Pocket (cellular) filters that meet the DIN 53438 standard (pre-filtration), the European standard EN779 and DIN EN 779 (class F5 internal filter) have the longest service life. In the above project drawing, the primary filter is indicated by the number 2, and the air intake by the number 1.

What is needed to create a paint booth

A DIY paint booth requires the preparation of tools and materials. Knowing what is needed will help you create an estimate for the work. This way you can understand whether it’s worth pursuing the process or limiting yourself to renting a camera. List of required materials:

• A room with dense walls and floors;
• Ventilation;
• Filter system;
• Thermal generator;
• Wall covering material;
• Reinforcement grid to cover the floors.

Organization of professional car painting booth

You can watch expert videos, study drawings, but still not understand how to build a paint booth with the necessary technical characteristics with your own hands. To paint a car, it is important to consider enough space around the car. Already at the stage of creating drawings, you will have to plan all the sizes and volumes, also taking into account the communications in the room. The following aspects will be important:

1. Ventilation . This point often takes up to half of the total budget. Install high-quality industrial filters at the inlet and outlet, use several supply and exhaust channels.
2. Interior finishing material . It should be a practical and smooth version of the material from which fresh paint can be easily washed off. Otherwise, you will have to constantly order chemical cleaning of the room.
3. Climate control . This system must be able to control air temperature and humidity. For different types of car paint, you will need different environmental conditions.
4. The mode of drying a car after painting is a significant increase in temperature for several hours, which also requires high tightness and thermal insulation of the building. Otherwise, the cost of a spray booth will be huge.

Not always, even for specialized purposes, all these features are taken into account. Cars can also be painted in less modern and expensive conditions. At the same time, some elements can not be purchased from complex expensive devices, but can be done with your own hands. To create good equipment you will need to purchase really high-quality blueprints. The best option would be to schedule construction separately for your project.

Requirements for a spray booth

There are certain requirements that should be taken into account to create a quality room for painting:

• High-quality ventilation and air purification are created;
• Adjustment of temperature indicators so that differences do not exceed 3 degrees during drying;
• Good lighting to see all the flaws;
• Compliance with safety rules.

It is important to make the room airtight; any breeze can greatly affect the temperature, which leads to the formation of defects.

What tasks does she perform?

You need to paint your car not just in the garage, but in a specially prepared place. This means a special camera that ensures the following conditions and functions:

1. Cleaning street air from dust, heated air, as well as paint residues and unpleasant odors.
2. Car painting. Here it is important to understand that for work you will still need air, which is drawn into the room, heated to 20 degrees, and then drawn outside.
3. Paint drying. Drying paintwork is a very long process that must be carried out under the most favorable conditions. To do this, you need to purify the air and supply it at a temperature of 60 degrees Celsius.

The spray booth has a huge number of advantages, among which is the complete absence of dust, which interferes with normal painting . The design of the air inflows ensures normal air supply and completely cleans it. In addition, there should be no drafts in the chamber, which is achieved by a unique ceiling system. Of course, such a pleasure is very expensive, but if you want, you can build such a camera yourself, and also paint cars professionally.

Mode of application of cleaning and ventilation systems

Air masses are purified through three filters: coarse cleaning, where dust and heavy particles are removed; cleaning, the filter is located behind the heating element; fine cleaning, which is located behind the air duct.

It is necessary to install the filtration system so that filter replacement is easy.

Do-it-yourself hood box in the garage

The modern construction of a spray booth must take into account the main point - ventilation. Indoor air purification is very important to remove dust, dirt and other paint particles.

Such systems are divided into single-engine and dual-engine. In the first case, air is pumped from above using a fan, and then removed independently through holes in the floor. In the second case, another fan is installed in the floor, and the system becomes forced. It is also more expensive, which also needs to be taken into account, although the efficiency also increases.

A well-thought-out ventilation system allows air masses to calmly and smoothly enter and exit the room. If mistakes were made at the design stage, then turbulence, turbulence and so-called “dead zones” where dirt will accumulate may occur. Therefore, air pressure must be taken into account. And for this purpose, filters on the ceiling are placed evenly along the entire length. If they are controlled from an automatic remote control, this is only an additional plus of ventilation.

Heating system

Working temperature standards must be observed in order to obtain a high-quality result without putting the painter at risk of health problems. The following points can be noted regarding the heating system:

• Conventional heating and electric heating elements will be sufficient for the winter period;
• A heat gun will help warm up the room and ceiling areas;
• A heat generator is only needed for large jobs, otherwise the expense is not justified.

Working temperature standards must be observed in order to obtain a high-quality result and not expose the painter to the risk of health problems.

Interior decoration and arrangement

For interior decoration, it is advisable to use non-combustible materials in order to comply with safety standards. This is how a metal profile is often chosen. Also, non-combustible materials are selected for thermal insulation work.

For ease of work, an area is allocated for storing the necessary equipment and materials.

Water curtain chambers

Such equipment is presented in several variations on the construction market. The choice is made taking into account the objects that will be painted in them. So there can be chambers without side walls and floor, with an active water floor and walls, etc. It is important to decide in advance what work will be performed in the chamber.

Rules for calculating ceiling and floor filters

The air filter is an important structural element of any car service center that paints cars. They are placed evenly in the room where the car body is painted. Such filters come in two varieties, for floor and ceiling.

The ceiling filter for the spray booth is installed so that it can be easily removed if necessary. For uninterrupted operation of the spray booth cleaning system, it is necessary to initially correctly calculate the minimum area of ​​the filter elements.

Each of these types of filters should ensure maximum cleaning efficiency of the box (indicators should exceed 99%). In this regard, cleansing is performed in stages:

• First, large particles of paint are removed from the air;
• In subsequent stages, small particles are removed from the air.

This technique requires the use of fine filters, thanks to which dust from the street air does not settle on the surface of painted metal structures. To calculate the minimum area of ​​ceiling filters, you need to know exactly the level of nominal air flow in the spray booth.

This parameter will need to be divided by the nominal air flow rate in the filter being used. The result of such calculations will be the minimum surface area of ​​the filters. Naturally, to achieve maximum efficiency of the entire system, it is necessary to install large-area filters in the box.

In a similar way, you can calculate the minimum area for filters on the floor. In general, a floor filter for a spray booth consists of two structural elements: a load-bearing sheathing and filter elements.

The painting booth drawing is created in several versions. Each of them has its own type of lathing with filters. The grille can be located directly under the car, or under the wheels of the vehicle.

Proper ventilation

In addition, the lathing can completely cover the floor of the chamber, and the filter elements in this case will be several centimeters below the level of the lathing.
