Features of painting a facade with a spray gun

When building country houses and cottages, one has to deal with the issue of surface finishing, including the facade. A special tool will help make the work easier - a spray gun, with which repair and painting compounds are applied. Moreover, it is suitable not only for painting walls and ceilings, but also for other construction tasks. In this article we will look at how to paint a facade with a spray gun, what nuances need to be taken into account during the work and how to choose the appropriate construction tool.

Application of electric spray guns

To understand which spray gun to choose for home use, you need to decide on the purpose of the tool.

For painting the house

Very often, spray guns are used to save time. This device allows you to evenly paint walls without physical effort. This method can be used for large areas and replaces manual labor. Using the device you can paint walls, ceilings, small objects and gates.

For car painting

Powerful electric spray guns are used to paint a car. Because the paint layer must be uniform. For cars, devices with a small nozzle diameter are used.

Note: Special vehicle models are designed for liquid paints that spread evenly on metal surfaces.

The equipment is often used for painting cars

Types of electric spray guns

Electric spray guns are the most popular. Since they allow you to evenly distribute the paint over the surface. Electric models are divided into the following types:

• Airless. Airless paint spraying is carried out using a high pressure pump. Often used to spray sticky materials.
• Painting stations. These units are called occupational units. They consist of a spray gun, a powerful motor and an air pump. They allow large areas to be painted in a short time and are most often used in industry.
• Airguns. This device works by connecting to a compressor. The paint is atomized with air, resulting in a uniform coating.
• Manual spray guns. The design looks like an electric motor and a spray gun with a paint barrel. All components are connected by an air hose through which air is supplied. This type of gun is very popular and can be used to paint various types of surfaces.

Which electric spray gun is better is determined by each user individually. Manual models are often chosen for painting walls and ceilings. These devices are inexpensive and easy to use.

The device type is selected individually by each user

Walther Pilot III glue gun - K

Pneumatic spray gun for various types of adhesives, made of stainless steel coated with Teflon, which prevents glue from sticking to the body of the gun.

A special adhesive rotary nozzle mixes air with the material with force, which ensures easy, high-quality spraying of thick adhesives.

The absence of side holes on the air cap forms a round torch and prevents glue clumps from clogging in the holes.

The tool works the entire shift without cleaning.

The air cap can also have side holes for low-viscosity adhesive materials to form a wide spray.

The advantage of the sprayer design is the absence of rubber gaskets.

The high resistance of the tool to the chemical effects of solvent-based adhesives, many years of service life without the need for repairs, and the industrial purpose of the sprayer have made this sprayer model very popular among furniture manufacturers and in the automotive industry.

The pistol comes with standard 1.5mm or 1.8mm nozzles.

What to look for when choosing a spray gun

When deciding which spray gun to choose for painting walls and ceilings, it is important to know which one is best. To select a suitable device, certain criteria must be taken into account.

Type

When choosing a paint sprayer for home use, it is recommended to give preference to electric and pneumatic types. Such devices quickly cope with the task and give good results.

Power type

Spray guns can be divided into mains-powered and battery-powered. Powered ones are more powerful. However, battery-powered models can be used offline.

Power

To perform the work, the rated power must be 1.3 - 1.9 kW. This is enough to uniformly paint the surface.

Pump type

The pump can be pneumatic or airless. The most commonly used are air pumps. Such units can easily cope with this task.

Please note that the airless type pump is most often used for painting walls with viscous substances.

Tank volume

The size of the tank depends on the surface being treated. The most common models have a tank volume of 2-2.5 liters. This size allows you to draw comfortably without physical effort. At painting stations, canisters with a capacity of more than 3 liters are most often used.

The size of the tank determines the amount of work that can be done

Additional options

In order for the device to perform its job properly, the following criteria must also be taken into account:

• Nozzle cap. To make the device durable, the cap on the nozzle must be made of metal.
• Possibility to regulate paint consumption. This option allows you to increase the paint layer in the desired location. However, such models have a high price.
• Injector parameters. This criterion depends on the viscosity of the material.
• The material from which the tank is made. Metal cans of paint are less susceptible to damage and the paint can be easily washed off. However, it is difficult to regulate the level of paint in them. Plastic ones are cheaper, but they are difficult to clean.

In addition, when choosing a spray gun, pay attention to the location of the tank. The reservoir can be located at the top or bottom.

Popular models

Today, there are several manufacturing companies on the construction products market that produce paint sprayers. Components may differ from each manufacturer. Sometimes they offer the tool itself, a fitting for connecting a hose and a filter to strain the paint.

Rating of the best spray guns for the home

The advantages of using a mechanized paint application method are obvious:

1. A thin, even layer is formed on the surface of the wall.
2. Economical paint consumption.
3. Increases the speed of work while reducing its labor intensity.

Spray guns can be pneumatic or airless.

Using an electric spray gun, you can easily work in hard-to-reach places

Best air spray guns

In a pneumatic electric sprayer, paint is supplied by a stream of air, and spraying occurs under pressure. This allows you to get an even layer of paint of small thickness. Electric pneumatic spray guns are divided into two categories. In the first type, the spray gun is combined with a compressor. The second type: a compressor and a spray gun connected to each other by a hose. Since there is no need to hold the housing with the motor in your hands, the device is lighter and your hand does not get tired during operation.

The main advantage of this type of equipment is low paint consumption and high efficiency. The disadvantages are the high cost of the equipment, the appearance of streaks due to the lack of experience with such a tool. The escaping air under pressure causes dust and sand particles to rise and stick to the painted surface. It is important to choose the right machine power. Those that are more powerful can work with thick compositions, while cheaper models with low power are suitable for liquid paints.

Dyeing technology

The work procedure is the same as for conventional painting. First of all, the surfaces are carefully prepared: cleaned of dust and debris, puttied and primed if necessary. After the primer has dried, start working with the spray gun. Before using the device, it is recommended to filter the prepared paint from large clots, which is done using a regular cloth.

Note! Before starting work, wear safety glasses and a respirator, since a large number of workers move freely in the air.

The surface should be painted at a distance of at least 40 cm. The jet is applied strictly in a perpendicular plane. Do not press the trigger directly in front of the wall, as this will cause uneven application. The device can be moved at the same speed, taking into account the distance from the wall. To achieve optimal results, it is recommended to paint in 3 layers, with the first being vertical and the second horizontal.

If you violate the painting technology, the consequences will not be pleasant: smudges, drops or bumps will form on the walls. If the paint is uneven, thick layers may begin to peel off over time. To find unpainted areas, it is convenient to use light - side lighting is placed near the plane.

How to choose

The question of which model is better to buy is not so simple. The final result depends on the right choice. Everyone has different selection criteria. Some are interested in functionality, others - how much it costs, and still others prefer to have a device from a rating of quality products. Everyone is right in their own way. Much depends on the area of ​​application and the expected result. Experts recommend paying attention to the following product characteristics:

1. Power. For household use, tools with a power of up to 500 W are sufficient. They have a minimum burner power and coverage area. Mortars may not be airtight. Experience and practice working with this category of products is required.
2. Equipment and options. Main components: gun, tank and power system. In addition to the basic kit, there may be additional accessories, such as silicone for sealing, nozzles for purging the tank, needles for cleaning nozzles, replacement nozzles, etc.
3. Pressure. The optimal pressure is 4-5 atmospheres. Liquid putty requires higher pressure. Pressure is affected by speed. Machines with a pressure of 0.6 bar are considered economical.
4. There is a pressure gauge. The pressure gauge is used to control the working pressure. The pressure gauge shows when the tool is ready for use. The pressure gauge is an integral part of the air gun. It is located on the compressor housing.
5. Material. Most air guns are made of plastic. The body of the air gun is made of metal (aluminum). Reservoirs are made of plastic or metal.
6. Characteristics of injectors. They are selected depending on the granulation of the mixtures used. Material viscosity, nozzle diameter, and air supply pressure affect the amount of solution flowing from the spray gun.
7. Weight and parameters. The weight of pneumatic products ranges from 0.25 to 1.6 kg, the length of the gun is from 120 to 250 mm. Large air or airless guns can weigh between 1.5 and 2 kg and be between 250 and 300 mm long.
8. Spray system. You need to take this issue seriously and carefully study the information about the equipment. HP means high outlet pressure, MP means medium, RP means low outlet pressure, HTE means high transfer efficiency, HVLP means low inlet pressure and high atomization, LVMP means medium inlet pressure and low atomization, LVLP means low pressure and low atomization.
9. Optional equipment. Additional equipment differs for each type of machine. For example, pneumatic products only work with a compressor to which an air hose must be connected.
