Paint sprayer is a convenient technical device for uniform distribution of the coloring layer over the surface. Different types of spraying devices greatly facilitate the process of work during the repair and decoration of premises or technical devices - a car, a refrigerator or walls.
Airless paint spray is a great way to provide high-quality, deep coating without the use of tedious and inefficient rollers, brushes that require manual labor. In fact, the concept of "airless" in this case is not too close to the truth due to the fact that in the composition of the devices there is a pump on a vacuum basis with a piston principle of operation. The piston allows the paint to be supplied from a bucket or barrel and transferred to the spraying element. The difference from air systems is that in this case air does not mix with paint.
Thanks to powerful pressure, the necessary potential is created through a nozzle with a special design. The result is quality coverage that even professional painters can be proud of.
Advantages and disadvantages
The benefits of using spraying mechanisms are as follows:
- greatly facilitated the process of repair and painting of a variety of surfaces in relation to time and effort;
- it is possible to achieve the highest quality coverage of complex planes, with irregularities, bends and angles that are difficult to paint with a roller;
- the toolkit is minimal: a bucket of paint, equipment and the availability of electricity;
- the work is carried out non-stop and does not require constant replenishment of paint in the tank due to the presence of a hose lowered directly into the barrel or jar;
- high efficiency in painting large spaces - facades, walls, fences, floors.
The disadvantages of such painting methods can be attributed primarily to the high speed of paint supply under strong pressure, which leads to a large consumption of raw materials. Working with a device such as a paint spray requires skill and experience. At the beginning painter the process will be slow, the distribution of the coloring layer will be uneven, with drips. But practice and long-term use soon enough will allow you to learn how to work with the device accurately, using all of its features to the maximum and achieving high-quality coverage.
Different surfaces require different instruments. The electric paint sprayer may offer the painter a more intensive operating principle and ensure the quality of work at a different level. These are universal devices that have in their kit a set of replacement parts.
A variety of attachments and other components allows you to paint well a variety of surfaces.They are convenient to distribute and paints and solutions. The weight of such devices reaches 25 kg. But within an hour with such a sprayer you can paint the space up to 250 square meters in area. And in the process there is an economical expenditure of coloring material, in the absence of a compressor.
Manual paint sprayer is a variant of the electric “colleague”, which gives the holder maximum freedom of manipulation, but works with a small amount of material and allows you to manually cover small surfaces that require special attention.Portable units are equipped with small batteries, which allows you to spot paint small areas: the walls of private houses, garages, fences.
Criteria for the selection of apparatus
Airless paint sprayer can be selected by the following parameters:
- reliability and quality of the brand of the manufacturer;
- durability and quality of work;
- stable material flow without failures;
- ease of use in solving a specific problem of repair;
- paint feed rate;
- the amount of painting work;
- material capabilities;
- independence from wage workers and comfort in use.
Any type of device will greatly facilitate the flow of paint and will improve the result and speed almost twice. There is an economy of labor and the most expensive resource - time. In this case, the most expensive option will be machine painting, and the cheapest - with a simple manual unit. Any option will help save paint - if the roller requires 1 kilogram of diluted liquid, the instruments spend an average of 0.5 kilogram for a similar area.
Paint sprayer is selected according to the needs of construction and repair.In one case, a small portable unit is needed. In the other - large-scale painting electric device with long-playing distribution.
Cost of devices
Paint sprayer, the price of which is significantly higher than that of a conventional roller or air sprayer, meets all the latest standards and fully justifies the costs and investments. The “old-fashioned” painting methods are certainly justified in some cases - with a one-time painting of small parts or economy, but the efficiency of the spraying machine largely pays for all the costs.
The cost of hand-held remotes today varies in the range of 1000 - 8000 rubles.Electric models start at a much higher price threshold, but are quite accessible to everyone.
For comparison, you can bring such "interchangeable" phenomena as a broom and a vacuum cleaner.If you wish, you can get by with the first option, but in the XXI century it is no longer relevant - the modern vacuum cleaner is more popular than the modern one. Ease of use, speed and quality of the sprayer quickly redeem all costs and efforts. Additional costs require highly professional equipment, which requires extensive experience and technical knowledge in maintenance.
The paint sprayer is a real modern equipment for repair and construction, which will provide a high level of work and will facilitate many processes.
