Painting equipment presented on the construction market has long been not limited to the traditional set of brushes, rollers and accessories. Today, this list is expanding, including through high-tech tools that allow you to optimize the process of applying paint and varnish coatings. Attempts to automate painting work, relieving the master from painstaking work, have been made many times. But the most successful to date is the Graco paint sprayer, available in several models. The advantages of this tool include an innovative approach to the implementation of spraying paintwork. However, there are many similar offers on the market that also deserve attention.
What is a painting machine?
Initially, the concept of spraying involved the use of two components: the spray gun itself and the compressor that ensured its operation. The need to purchase two units to perform one function complicated the choice on the part of the user, as a result of which the idea arose to combine these elements into one complex. Modern paintingthe device resembles a small station designed to spray the working composition onto the surface. This set includes a spray gun directly with a nozzle that discharges the solution, as well as a block in the form of a compressor unit. However, the composition of the package may change. For example, today the airless spray system has become popular, which is worth talking about separately.
Airless spray method
The peculiarity of this approach to spraying is the operation of the pump, which exerts force through the hose. In essence, spraying is carried out using the same pressure as in pneumatic devices, but its performance is much higher. Compared to traditional tools of this type, the airless spray gun allows the composition to pass through a nozzle with a small diameter. This solution has both pros and cons. As for the advantages, they are the ability to work with viscous paint and varnish solutions. When leaving the nozzle, the composition is crushed, so there are no problems with application.
However, the high pressure force also causes disadvantages in the form of the formation of sagging on the working surfaces. For this reason, the airless paint sprayer is not suitable for delicate painting operations with high demands on the quality of the finish.
Main features of the tool
When choosing this station, one should take into account such parameters as engine power,performance and pressure. The power potential of electrical units varies from 2 to 5 kW. In this range, the equipment can deliver up to 10 l/min. Small low-power devices produce about 5 l / min. One of the main performance indicators of this equipment is pressure. It is this characteristic that fundamentally distinguishes the new models of airless devices from classic air guns.
So, in the standard version, the high-pressure paint sprayer provides 230 bar. This value is comparable to the performance of professional spray guns operating in combination with piston and screw compressors. Accordingly, with the help of such a unit, it is quite possible to paint a surface of a large area in a short period of time, for example, a production site, a ship deck, a tank or a wagon.
Varieties of painting machines
The equipment is available in two versions: with electric and gasoline engines. The first models are focused on construction and repair operations, including cosmetic interior decoration, and larger industrial events. The advantages of the electric motor include small dimensions and maneuverability. In addition, high-performance models with this drive allow the connection of an additional spray gun. The gasoline paint sprayer is usually characterized by independence in terms of freedom of movement and high power. For theseadvantages the user will have to put up with the exhaust of spent fuel, because of which such a station is problematic for indoor use.
Reviews about the model from Graco
It's worth starting the review review with the company that laid the foundation for the new generation painting equipment segment. One of the most successful developments of the company is the Mark V unit. It is used both for industrial purposes and in solving household chores. Users note that the Graco Mark V paint sprayer effectively copes with interior and facade work. The unit easily sprays even thick acrylic and latex compounds, as well as epoxy paints and putty mortars. Praise the owners of the equipment and a wide range of equipment, which includes the spray gun itself, a protective device and a double-sided nozzle with adapters and hoses.
Reviews about the model from Wagner
One of Graco's few competitors in the paint equipment market is Wagner, which attracted the attention of many professionals and ordinary users with the rather successful HeavyCoat 950 G. This is a high-power unit that is available in both electric and gasoline versions modifications. As the owners note, the Wagner painting machine in this version provides not only a high speed of applying paint, but also a high-quality formation of the final coating. That is, the mainthe problem of airless spray guns is the presence of smudges and bumps. The Wagner model delicately applies both light formulations and acrylic solutions. Masters who work with interior finishing speak best of all about this unit, since this direction requires not so much high performance as the quality of the applied coating.
Reviews about the model from Titan
Another development from the general family of airless painters. If the previous two models are still focused on working with large volumes, then the Impact 740 device specializes in high accuracy and accuracy of painting. The owners of this model appreciate it for its mobility, compact size and robust design. Separately, the benefits of a special regulator are noted, thanks to which the painting machine can supply different volumes of the solution. At the same time, the range of compositions suitable for work is also quite extensive. This list includes water-based products and one-component materials, as well as enamels and primers.
The nuances of equipment operation
Before performing painting operations, it is important to fix the unit with the engine in a stationary position. Some models provide for the possibility of lifting the structure on special steps. In such cases, you should be especially careful about security measures. Then you can proceed to connect the unit and directly apply the composition. Almost all airless paint sprayers contain in the basic configurationspray gun. With its help, surfaces are coated with a paint and varnish mass. In the course of work, the user can also adjust the composition supply parameters depending on the requirements for the final result.
Conclusion
Unfortunately, it is not yet possible to embody all the necessary qualities of modern painting equipment in airless machines. Even the Mark V paint sprayer, which is one of the best representatives of the segment, is not suitable for surface finishing. This possibility is supported by models from Titan and Wagner, but they have their drawbacks. For example, compact models for delicate application of paint are not suitable for use in large-scale projects. Therefore, in the selection process, one should focus not on the versatility of such devices, but on their ability to cope with specific tasks. In their niches, all models demonstrate good results, allowing you to perform both stylish interior decoration and ennoble massive industrial structures.
