How to choose a spray gun for painting your home?
Many have probably faced the problem of staining various surfaces. This procedure can be difficult over a large area. Although the work can be done by hand with paint brushes, this method is not very effective when it comes to large volumes - houses or all kinds of structures. It is easier to do such a complex job with a spray gun. Today we will talk about the features of such tools, about the choice, about the painting technology.
Peculiarities
It is better to paint a large surface using specialized equipment, which is a spray gun.
The spray gun is used by professional painters in a variety of industries - from tire fitting to restoration work and other painting services.
You can use it:
-
for painting the ceiling, walls;
-
for whitewashing and priming;
-
applying varnish;
-
a tool for painting a wall or fence is suitable;
-
removing old wallpaper;
-
used in the manufacture of garden or country furniture, other structures made of wood;
-
for spraying plants or shrubs with fertilizers or insecticides.
Externally, the device looks like a pistol with a trigger, as well as a handle and paint containers. The speed of the work will directly depend on the volume of the tank. It is more convenient with a large tank, since there will be no need to frequently add paint to it, which will affect the speed of work.
A pneumatic spray gun allows to ensure high-quality application due to dispersive crushing of the paint composition. Usually this technology is used for small spaces or products. Excessive overlaps and overlaps can occur when paint is applied to large areas.
When working with a spray gun, it is important that the distance between it and the surface to be treated is the same; you should also not forget about the same speed of movement of the tool.
Spray guns can be used for different surfaces. These can be metal structures, wooden products. Wood staining has its own characteristics. Before carrying out the procedure, it is necessary to remember about the uneven absorption of paint in different areas. So, on soft layers, after applying paint, it will look matte, and on thicker layers, it will shine.
This effect can be enhanced by treating the texture with a stain or varnish protection. You can use a tinting varnish, due to which the texture is manifested and its color. Toning it allows you to recreate the structure of more valuable tree species.
Tool selection
When choosing a tool, the approximate amount of work that needs to be done is taken into account. The principle of operation of models of various types is identical, allowing you to create an aerosol and apply it to the surface to be treated. Each model has a spray head, nozzle and valves to adjust the paint and air flow, and a trigger hook. Some models may have a pressure gauge.
Devices can be subdivided into certain types.
-
Manual models. Such a spray gun is a primitive device in the form of a cylinder with a pump, an outlet hose and, accordingly, a spray gun. Air, when pumped inside, will create pressure, which will decrease as work is done.Such an aggregate can be suitable for painting any surfaces, if there are no special requirements for quality. Hand-held paint sprayers are cheap, while their work does not directly depend on the availability of electricity.
- Pneumatic. These are quite powerful devices with considerable performance. If you need to paint walls, wooden surfaces or metal products, you should pay attention to these models. They can differ depending on the pressure and air volume. These tools are most suitable for working on surfaces that absorb moisture well. The disadvantage of such products is the application of a layer of paint on the surface that is thicker than required. When working with wooden surfaces, this disadvantage can be ignored.
- Electrical. Such spray guns have many advantages. They are quite powerful and have high performance. The quality of staining with such a device will be slightly lower than that of a pneumatic model. Such a device is more suitable for household household work.
An electric spray gun is considered to be a household tool, while professionals usually choose a pneumatic one.
Such models can be air or airless. Their peculiarity can be determined by external parameters.
If the need for the device does not arise so often, you can purchase an airless tool that has a low cost. The main thing is not to forget to rinse it well after working with it. The main advantage of airless models is good performance with low power and low cost.
If the device will be used quite often, but the volume of painting will be small, it is worth choosing an air device with an average power.
Professionals should look for powerful, high performance paint sprayers suitable for large areas.
When purchasing a model, you should make sure that there is a viscometer in the kit, which allows you to dilute the paint to the required consistency. A small orifice cup will help determine the recommended viscosity level for normal operation.
If the work will be carried out with powder paints, then it is necessary to set up the spray gun on a special apparatus using a computer. Usually such devices are used by professional craftsmen. When working with dispersion paints, choose a tool that is suitable for working with substances with different densities.
When choosing a device for painting different types of surfaces, you should pay attention to certain points.
-
As tools for painting metal surfaces, pneumatic as well as electrical devices can be used. When working with different types of paints, it is necessary to select the appropriate paint for a particular type of paint.
-
For painting wooden surfaces, an electric device is more suitable in the absence of pneumatic equipment. Choosing the right paint and diluting it to the desired consistency is an important task in this case.
-
When painting walls, that is, when applying paint on a vertical surface, you can take any spray gun. At the same time, it is very important to choose the right parameters for work.
To paint a table or chair, it is enough to use a low-power model up to 500 watts. For large surfaces, for example, for walls, choose an appliance with a powerful motor over 500 W.
Painting technology
Painting any surface is a critical moment. To get a good color of paint, it must be thoroughly stirred in a jar. Experts recommend preliminary painting and see the result of the work. When dry, the color of the paint can be very different from when it is wet. Coloring is recommended in calm weather, it is desirable that the sun also showed little on this day. In the absence of wind, dust and debris will not get on the treated surface, and in the absence of the sun, the paint will dry faster.
To paint a house from a bar or lining inside and outside with your own hands, it is advisable to use a spray gun.
The technology of its work consists of several points.
-
To adjust airflow and ink movement, hang the spray gun vertically, holding it a short distance from a sheet of paper or newspaper.
-
After pulling the trigger, it should not be released until drips begin to form.
-
Adjust the settings if necessary.
-
Next, turn the nozzle until a fan-like torch is formed. It is advisable to practice and achieve spraying strips with an overlap in different directions.
-
To create a uniform coating, the tool moves evenly, at the same speed, painting over a certain interval.
-
Having gained experience, you can start your main job. Initially, you should determine the order of work, dividing the facade into zones and highlighting the main zone. Processing is carried out starting from the last zone.
-
It is necessary to pull the trigger not at the beginning of the wall, but at its edge. The sprayer is not tilted during operation or moved in a wave-like motion.
-
The trigger should be released when grasping the opposite edge of the work surface.
Using this method will allow you to paint a wooden house from a bar in the country, a wall, a fence, garden furniture or other building.
The main thing is not to use translucent formulations. In this case, the covering coating technology is used, painting the wall with opaque compounds to exclude the visibility of overlaps.
