Painting a car is not easy, it requires at least a special room. Plus, professional equipment for painting a car is expensive - all this scares away those who want to go into the painting business, although this business is considered very profitable. As usual, all the necessary equipment is assembled gradually, and an ordinary garage is used as the main room. An alternative option is a do-it-yourself paint booth. With proper and skillful design, it will not yield to its characteristics acquired in a specialized center. Learn how to make it yourself from this article.

Basic requirements for spray booth

The main rule that must be followed is a warm room with insulating walls. They are required to maintain a constant temperature inside about 20-25 degrees, this applies to both the air and the surface of the car. Fulfillment of this requirement is necessary for carrying out a high-quality technological process. Therefore, when arranging such premises, which are spray booths for cars, the designer is advised to carefully consider how the required temperature can be reached - this can be an air heating system, good thermal insulation, etc.

You can warm up the air with the help of powerful heating elements, but to maintain the desired mode, thermal insulation cannot be replaced by anything. The temperature difference should not exceed 3 degrees for the entire drying time. Sudden heating and cooling of the spray booth is highly undesirable.

A painting booth, which you can do with your own hands with high quality and without unnecessary overpayments, needs high-quality lighting. It should be everywhere, especially carefully the workplace should be highlighted. To create daylight, you need to combine different fixtures. In addition, it is necessary to provide shadowless lighting of the central place of the painting room. In the working box, flickering of lamps and too cold or warm shades of glow are not allowed. It is advisable to give preference to explosion-proof lamps, otherwise conventional lamps will have to be additionally isolated and protected from fragments entering the room and onto the painted surface of the car. The quality of painting directly depends on the purity of the air and its pressure, in this case a good ventilation system will help.

Thermal insulation of spray booth

To keep the heat in the room, it is better to use polyurethane foam. Sometimes the box is equipped with foam plates, the gaps between which are filled with construction foam and subsequently sheathed with iron sheets, plastic panels, etc. Before you make a spray booth with your own hands, you must remember that both of these materials are combustible. In addition, the foam is easily destroyed by aggressive substances such as thinner or gasoline. Sometimes mineral wool or non-combustible materials are used for thermal insulation. Everyone knows that after finishing the car painting procedure, it is necessary to clean the room. Therefore, the walls should not only be fireproof, but also easy to clean.

Paintbox lighting

Any do-it-yourself spray booth device will not be able to function well without good lighting. The best option are halogen lamps. For safety reasons, they are isolated in separate boxes or fixed under special glass.

Fluorescent lamps are no less popular, especially since there is no need for additional protection. They can be placed on walls or ceilings. Portable lamps are used to illuminate the underside of the vehicle.

What should I consider when designing a spray booth?

Most often, a paint box is made from an ordinary garage, so safety rules are extremely important, because painting is a dangerous procedure that can lead to an explosion. Be sure to follow the following rules:

  1. The heater must be located in a separate room in a special box. Then the warm air will enter the chamber already heated, and the heaters will not be able to ignite the cloud from the spray gun, which can lead to an explosion.
  2. When a do-it-yourself spray booth is set up, you need to use the simplest methods for drying a painted car. It is better to use infrared lamps. It is desirable that they are included in ordinary sockets.
  3. Separate RCDs are needed for the outlet group, generator and welding machine. You need to calculate the total power consumption of electrical energy in advance, or better, contact the electricians.

Ventilation system device

The ventilation system for the spray booth is an indispensable element of its design. It is a complex configuration of air ducts, various valves and fans. In addition, the ventilation of the spray booth must be combined with air purification filters and a room heating system.

The ventilation system performs several functions at once, here are the main ones:

1. It filters and purifies the air, thanks to it, air vapor and gas emissions from paint and solvent leave.

2. Ventilation ensures the safety of work, the air after filtration does not harm the environment.

3. She organizes safe work. A properly designed supply air ventilation system, even in a limited and enclosed space, where a large amount of toxic substances are concentrated, ensures a safe cleaning process. The risk of fires and explosions is minimized.

4. The system provides hot blowing and drying. When painting a car directly, the ventilation of the spray booth performs its main functions with its own hands, and also creates hot air flows that speed up the drying process of the paint, and hot blowing better bonds the layers of paint and varnish together.

Types of paint boxes

Well-thought-out and correctly calculated ventilation can not only affect the quality of future car painting, but also save electrical energy, reduce the cost of necessary filter replacement. All this must be remembered, especially when a do-it-yourself spray booth is set up.

There are several types of ventilation systems, all of which depend on the purpose of the paint boxes:

1. Air passage ventilation chambers. The principle of operation of this ventilation system is that air flows at a constant pressure, preventing any ingress of debris into it. The space must be absolutely airtight.

2. Chambers with increased pressure or rarefied air. They are two working fans. One pumps air, the other sucks. Their joint work gives the necessary pressure difference. This ventilation is suitable for open spray booths without walls.

3. single motor cameras. Principle of operation: air is supplied from the outside from above and naturally squeezes out paint and varnish vapors through the lower openings of the spray booth. This type is quite acceptable for a home-made box, which is a do-it-yourself spray booth.

4. Twin cameras. Clean air enters from above, an additional motor pumps air from below and takes it out of the room. This system is very effective, but this expensive equipment is suitable for painting cars on stream.

5. Chambers with supply and exhaust ventilation. This system is designed together with a heating and filtering system.

Filters for spray booths

The spray booth must be safe. The presence of dry filtration of air masses will help prevent a fire or explosion. Even when installing a water curtain, the use of dry filters is still relevant. In the premises it is much more rational to use filters for spray booths in the form of rolls. They are a fiber impregnated with a special anti-flammable compound. This material covers the entire ceiling of the chamber.

Floor filters get dirty much faster and harder, which means they need to be better made. There are two types of filtering:

1. Fiberglass roll material. It is non-flammable, and its use is designed for a certain number of times.

2. Inertial filters for spray booths that mechanically separate solid large particles of debris when the air flow changes abruptly.

Additional cleaning

If you clean the filter systems correctly and in a timely manner, you will not have to change consumables often. Fine cleaning consists of additional large volume pocket filters. They are installed in the duct. To save space, you can use outlet cassettes or honeycomb filters to collect microscopic aerosols inside.

DIY Filtration System

When designing a cleaning system, it is necessary to take into account its location. It is better to install a coarse filter, only then you can proceed with the installation of a ceiling filter. If the do-it-yourself ventilation of the spray booth works on the principle of air recirculation, then it is necessary to install several cassette filters inside it with a high accuracy class. They must correspond to the type and design of the ventilation system. It is desirable that a system hours sensor be available. Filter surfaces are recommended to be cleaned and blown regularly. All these actions extend the life of the filtration system.

Powder Spray Booth

Many people use powder paint during their work. This is a mixture of fine particles with the necessary impurities. A do-it-yourself powder spray booth is a complex project, but quite feasible. It is necessary to purchase special equipment, without which the painting process is impossible. It is uneconomical to use such boxes in small repair shops, since the equipment is quite expensive. In addition, these boxes will not be able to carry out the desired tinting.

Powder chamber consists of systems for filtering and recuperating the composition of the paint. Before starting, the mixture is magnetized, it sticks to the metal surface of the car in a dense and uniform layer. Next, the paint layer is sintered, for this the car is heated to a certain temperature and kept for some time. The powder melts under the influence of high temperature, thus, the car is painted. The powder chamber greatly reduces the cost of painting a car. The remaining composition is collected by filters and can be reused in the production process.

Hurry is unacceptable in the arrangement of the spray booth, especially when it is done with your own hands. If errors need to be corrected, the workflow will be stopped, and this will lead to the loss of customers. With a huge selection of modern equipment and materials, this article will help you make a do-it-yourself spray booth, which will soon bring a good income.
