In the conditions of modern production, the application of paints and varnishes has become automated, which allows you not to waste a lot of time on this process. But qualitative changes also affected household painting. To do this, use HVLP spray guns.

What it is?

These devices are required primarily for dyeing products. They are spray guns with several components . These include a gun, a lead wire, a compressor, and a container containing the coloring liquid. Externally, spray guns are similar to standard spray guns that are used to clean windows, furniture, and apply liquids.

The essence of the work is to supply power to the compressor, which creates pressure . It is this that will allow the material to exit the gun, thereby spreading the substance to the treated surface. The very idea of creating an HVLP was realized in the 80s of the last century, when the need arose for a more convenient and faster version of dyeing products.

HVLP stands for High Volume Low Pressure means high volume and low pressure.

This principle allows you to perform work in the most environmentally friendly way, since the content of paint and other substances in the air is reduced . You can process parts accurately and accurately while doing the least amount of damage to the environment. It cannot be said that HVLP models require the installation of not only a compressor, but also special filters for air purification. It is they who make this type of device more environmentally friendly.

Spray guns of this type work best in everyday life when you need to paint something without any inconvenience . The average volume of work performed together with the low price makes the HVLP the most suitable option for private use. And also these paint sprayers are used in car repair when painting various components of vehicles. One of the main advantages of HVLP is ease of operation and low price compared to other types of spray guns.

Device

The main parts of these devices are the gun, container and compressor. The latter is absent in LVLP models that operate through an electrical system . In this regard, it is important to pay attention to the compliance of the compressor with the necessary characteristics of the spray gun. The tip in this case is a nozzle of a certain diameter. This characteristic is very important when spraying substances, as it allows you to perform work in different variations.

The container has two types of fastening, namely: upper and lower . The latter option is more preferable, since it does not obscure the view of the details. There are adjustable cups that can be installed on any part of the device around a 180-degree circle. Thus, you can customize the equipment based on the convenience and working conditions.

It is possible to change the pneumatic effect of pressure and air flow to set a certain tempo for the tool . In this case, the correct setting is important, since it significantly affects the quality of work. Professional models have more options for changing spray guns, which expands the scope of their application. Naturally, they are also equipped with more attractive features that allow you to do more work.

The technical device and design principle of this type of paint sprayers has both an advantage in the form of a noticeable saving of paint and varnish material, and a disadvantage . It is associated with a short range of application, so it is necessary to process parts at a distance of no more than 15 cm. With high pressure, you can apply accurately, but the low volume of paint released will not allow you to do this at full strength.

You will have to get pretty close, and you need to understand that the user will not be able to complete a large displacement as quickly as it is done with other types of sprayers.

Choice

The selection of any technique, including spray guns, depends on many criteria. Since the HVLP models are specific tools with their own field of application, it is not necessary to determine the working volume in this case . An important characteristic is cost. In most cases, consumers are looking at low to mid price range products where there is a wide variety. These models have everything you need to reliably perform tasks, while at the same time paying for themselves when it comes to use in small industries.

The choice of the manufacturer is equally important. At the moment, there are a lot of them on the market of spray guns, due to which the consumer has a good opportunity to choose the most suitable painting tool . If you have definitely decided on the company and are confident in its product, then here it is worth starting from the model range.

In situations where you are thinking about a manufacturer, choose the one with the best customer reviews. Some companies, Bosch or the domestic Zubr, have been on the market for a long time and are loved by the consumer.

Study the reviews of each model, since the quality of the manufacturer does not apply to all models, so there are both successful and not the best ones among them. Now you can find not only general information about the tool, but also a whole instruction that will give you everything you need to understand whether this spray gun is right for you or not. Don't forget about specifications and design.

Some power users pay attention to these traits first before buying, as they represent the basis of all the use of the technique.

Customization

Spray gun debugging and subsequent operation is an important part of the workflow. As mentioned above, the HVLP models, however, like the others, are adjustable. These changes affect air flow and pressure so that the user can choose between which application they want . Before adjusting, prepare the cardboard, it is on it that you can check the accuracy of the adjustment. After setting the parameters, apply the material to the test piece each time. This will ensure the user is using the correct air flow / pressure ratio.

It is important to understand that painting different materials requires their own adjustment . Be aware of the shape of the part as there is not much pressure required to spray directly. If you paint objects that are complex in their structure, then make sure that the setting is correct, and the substance is applied evenly.

The user can install a different nozzle or adjust an existing one in order to change the spray of the paint by its diameter, which must also be considered as an important adjustment option.

Apply paint smoothly vertically and horizontally for best results. In this case, the first few layers must be done in a row in order to create a kind of base. Then take short breaks, thereby allowing the material to infuse, and then apply layers again. Do all the work carefully and gradually, because this is how there will be no poorly treated areas on the surface . Before using the tool, it is necessary to properly prepare the dye itself. It needs the addition of a solvent, and in a certain proportion, which is indicated in the instructions. After that, adjust the supply of paint based on its consistency and quantity, having previously checked everything on cardboard.
