Technical progress and the introduction into operation of various devices that facilitate this or that work also apply to the conduct of repair work. Some modern tools are used in conjunction with materials that have been in use for many decades. For example, the use of spray guns and whitewashing for surface treatment.
Features of the
When the question arises about finishing work related to the ceiling in the room, there is a need for a convenient and effective tool that will help solve this problem.
When planning to perform work on whitewashing the ceiling or walls, you can use a roller or a brush, but surface treatment in this way will take a lot of time, and the process itself will be associated with discomfort and various difficulties.
In order to optimize and facilitate such work, on the modern market there are special devices for painting surfaces. They are called spray guns, some call this product a spray gun, a spray gun, and so on. The spray gun is of manual, pneumatic and electric type.
The main feature of working with guns for painting is the level of safety that they provide to the master, because everyone knows that the lime solution is quite caustic, therefore, in contact with the skin of a person, it can cause a burn. When using a brush, such cases arise very often, and the use of a spray gun excludes the presence of such unpleasant situations during finishing work.
It is quite difficult to apply a uniform layer without streaks to the surface with liquid lime, and the gun allows you to spray in an even layer, treating even the most inaccessible areas.
The use of a mechanical spray gun for whitewashing does not require a stepladder, since special fishing rods available in the device will make it possible to paint over ceilings and corners between the ceiling and walls, while being on the floor.
Hand tools will save the time required for painting as they are powerful enough to tackle a large work area, working on a principle that allows you to paint substrates with minimal contamination and splashing.
As practice shows, a manual spray gun of 20 V, as well as other models of devices, with or without a reservoir tank, quickly and efficiently cope with the implementation of repair work in the premises with their own hands.
The standard type of mechanical whitener is a small volume container into which a colorant, lime, chalk solution, or any other liquid substance is pumped.
The main component of the tool is attached to the reservoir - a handle that has a button that controls the course of spraying the composition, the angle of application and the intensity. In addition, the spray gun is equipped with a nozzle from which the solution exits to the base.
Today on sale you can find a large number of modifications of mechanical tools used for whitewashing, they differ in their design characteristics and cost.
For industrial purposes, hand sprayers are rarely used; their main area of application is operation in private houses and apartments.
Another model of hand-held spray guns is considered to be a piston tool; it is notable for its size and a slightly different principle of performing work.
In such a device, air injection is carried out by analogy with a conventional pump when inflating. The container contains several hoses, one of them is connected to the container in which the base treatment compound is located.
The second hose has a sprayer at the end; it is an elongated metal tube with a button and a nozzle.
The advantages of hand sprayers include the following tool qualities:
- simple configuration - the spray gun is very easy to disassemble, which allows, if necessary, to replace any part that has become unusable;
- ease of use - any master can regulate the supply of the composition, even a person with minimal work experience;
- hand-held spray guns are universal devices that are suitable not only for working with lime and chalk, but also for any other type of base colorant - the tool is recommended for use with any finely dispersed colorants;
- the products have a low cost, the most expensive device is considered to be a pneumatic spray gun;
- the applied composition lays down in an even layer;
- there is no need to use additional devices in order to process hard-to-reach areas of the base.
The disadvantages of the device include the need to manually maintain the required pressure in the tank so that during the work a constant rate of application of the composition is maintained.
Purpose
The spray gun is used to treat working surfaces with coloring compounds, lime solutions, stains, primers, or as a humidifier for surfaces using ordinary water. With the right choice of hand tools, it can be used to work with toners and nitro varnishes.
A manual sprayer will cope with whitewashing much better and faster in the course of independent work.
You can rightfully appreciate the advantages of the device already in the process of whitewashing the ceilings, since the main difficulties arise precisely in this area of the room.
To ensure the reliability and efficiency of the hand tool, it should be borne in mind that its design must meet the following requirements:
- a very important nuance is the weight of the device - during work, the specialist should not get tired of the extra load emanating from the sprayer;
- the holes at the nozzle must be of different diameters;
- the main structural elements must be made of a material that is resistant to wear and corrosion.
To be sure that the surfaces will be whitewashed properly when using the sprayer, you should adhere to a certain technology for operating the device:
- when starting processing, the tank must be filled with the composition only partially;
- after that, you need to remove the filter from the device and perform about 10 double approaches of the stem, this will help the device to fill with air;
- the exit of the liquid in a small uniform stream will indicate that the spray gun is functioning properly;
- from excessive splashing of the composition, a uniform and smooth rise of the stem will save, strong pressure should be avoided;
- when the pressure level is reduced, it is necessary to bring it back to normal, since this can cause the formation of a too thick layer of dye on the surface;
- at the end of the work, you need to disassemble the device and thoroughly clean all its parts.
Manufacturers
Manual whitewash sprayers have been around for a long time. Among the most demanded models it is worth highlighting the devices SO-20V, KRDP-5 (4) … Almost all products have similar characteristics, and the main difference is the weight of the device and its cost.
For an overview of the SO-20V manual spray gun, see the following video.
Manufacturers of hand spray guns are the following domestic and foreign companies: KSOM, Profmash, Auarita, Bosch, Einhell, Forte, Intertool, Miol.
Sprayers allow you to work with lime and chalk solution in rooms where the ceiling height can reach 3.5 meters, without the need for additional devices, such as scaffolding or stepladders.
The design of sprayers is quite simple, so malfunctions are rather the exception to the rule.
Experts recommend giving preference to domestic products, since the tools offered by foreign companies are quite often produced in China, therefore the nozzle body is made of low quality plastic, as a result of which the devices have a short operational life.
The nozzle of the spray gun must be made of hard-alloy raw materials, and the elements that will come into contact with aqueous solutions during operation must have a special protective coating that prevents the formation of corrosion.
Domestic products are manufactured taking into account all of the above nuances, and in the tools it is possible to adjust the extension for paint supply based on the height of the working surface, which facilitates processing.
Tips & Tricks
Before buying a hand-held spray gun, you must clearly identify the purpose for which the tool will be used. Having decided on this issue, it will be much easier to make the right choice, since the range of modern tools is quite large.
Mechanical sprayers are the most budgetary option for devices, pneumatic tools are expensive, electrical appliances are mid-range products.
The selection of the device is based on the following product characteristics:
- the volume of the solution tank;
- power;
- pressure.
Each parameter directly depends on the other - that is, a larger tank will have a higher performance. The optimal pressure is considered to be 5 bar.… Products most often have a tank volume designed for two liters of composition.
You should buy a manual spray gun for whitewashing only from trusted suppliers who sell quality products.
New the solution should be pre-tested on a surface, before proceeding with the processing of the bases in the apartment, thus, it will be possible to once again be convinced of the appropriate consistency of the composition. Before work, the liquid should be drained without fail … This will save time, since the sprayer will be much less clogged.
The effectiveness and uniformity of the treatment will depend on maintaining a uniform spray rate of the whitewash. At the end of the work, the remaining liquid can be usefully used as a treatment for trees in the yard.
Preparation for independent use of a whitewash sprayer includes the following points:
- the efficiency and correctness of the composition will depend on the size of the nozzle orifice, so it is worth adjusting it, bringing it to the smallest size;
- to strain the solution, it is worth using a sieve, the cells of which will be no more than 5 mm, in addition, gauze is perfect for such tasks;
- In order to prolong the life of the hand-held whitewashing tool, regular maintenance of the device should be carried out.
Experts recommend performing checks every month.
Besides, the instrument must be thoroughly cleaned after each use and conduct a detailed inspection for the formation of possible defects. For these purposes, a visual inspection of all structural elements is performed, after which the gaskets are checked, as well as the functioning of the device.
