Many people today still continue to plaster walls using buckets. In this case, the mixture does not always go as it should. In the end, the master has to correct the surface with a rule, as well as compact the plaster. If you want to cope with repair work in the shortest possible time, then you can use the plaster gun.
Description
Using a plastering gun, you can mechanize most of the operations. The manufacturers of such a tool assure that their equipment is capable of working with solutions of any density. If you use a bucket, voids may remain in the thickness of the plaster. When using a gun, the finish is dense, has no cavities and does not form cracks after drying. If we consider this tool on the example of the Western KP-10 model, then we can note that the minimum compressor capacity is 165 liters in one minute. The maximum rate can be 250 liters per minute. The minimum pressure is 3 bar, and the weight of the equipment is only 1.4 kilograms. The tank is made of nylon, and its volume is 5 liters.
The scope of such a device is wide. The gun can be used for applying mineral marble plaster, heavy paints, liquid wallpaper, putties and plasters. Unlike manual work, the gun drives the mixture under high pressure, which guarantees the absence of a cavity and pores. In the end, it is possible to form a homogeneous and dense layer. Nozzles are made of stainless steel, which is resistant to minor damage and corrosion. The master can in the process of regulating the flow of material by installing nozzles of different diameters. This functionality allows you to create many textures. The case is made of aluminum alloy and has the ability to withstand heavy loads.
Gun device
The plaster gun has a short barrel, which is a kind of nozzle. Nozzles are screwed onto it for different degrees of spraying. At the top of the equipment there is a funnel, which has a volume of 5 liters. The gun is equipped with a handle with a trigger, which can be compared to a bicycle brake. At the back there is a thread for connecting a high pressure hose, air flows from the compressor through it. Depending on the model, nozzles can be supplied that allow working with mixtures of different densities. Due to this, the plaster gun can be used for applying decorative and rough plaster. If you have to work with pasty formulations, then the pressure should be high. That is why the compressor power can reach 4 atm, while the productivity will be equal to 250 liters per minute. In some cases, a purge pestle is included with the spray gun, which is required to clean the nozzles when they are clogged.
Marshalltown pistol specifications
One of the manufacturers of the described type of equipment is Marshalltown, a plaster gun of this brand has a weight of 1.8 kg. The volume of its tank is 5 liters, and the diameter of the sleeve is 4.5 mm. About 170-250 liters of air are consumed in one minute. Dyuza is made of stainless steel, and the body is made of aluminum alloy. Among the design features - the ability to adjust the flow of the mixture, as well as the presence of a clamp lever for feeding the composition. The design is ergonomic, light weight facilitates the work.
Hopper brand pistol and its characteristics
The plaster gun "Hopper" is more popular among buyers compared to the above option. Its cost is 2600 rubles. The equipment has an air valve, which provides the ability to adjust the pressure. The tool can be used for applying decorative plaster, thick and textured paints, varnishes, multicolor paints, as well as liquid wallpaper. With its help, the master will be able to cope with the application of a composition of liquid cork and marble chips. The diameter of the nozzles allows you to adjust the fraction of the mixture. With a pistol, it is possible to apply enamels and primers, as well as textured materials.
Design features of the Hopper brand pistol
The plaster gun described above has an aluminum body that is capable of undergoing high loads. With prolonged use, the wizard will help the clamp of the feed lever. Fatigue when applying the mixture will reduce the ergonomics of the handle and the smoothness of the trigger. Due to the fact that the tank is based on nylon, the equipment is light in weight and exhibits chemical inertness. You will notice that the surface of this part of the gun is resistant to mechanical stress. The nozzle diameter can range from 4 to 8 mm, and 6 mm acts as an intermediate value. It is possible to use in the process of work the maximum permissible fraction size of 6 mm.
The compressor of the plaster pistol of the Hopper brand sets at the exit of 180 l a minute. With the help of this equipment you can trim not only horizontal, but also vertical surfaces. In one shift, which is 8 hours, the master will be able to finish 200 m 2 of the surface, while the layer thickness will be 3.5 mm.
Reviews about the gun Wester KP-10
You can buy this model for 2200 rubles. Its minimum productivity is 165 liters per minute. In the same amount of time, 250 liters of air will be consumed. Consumers note that the Euro quick-coupler adapter, as well as interchangeable nozzles, the diameter of which varies from 4.5 to 8 mm, simplifies the work. Many masters after acquiring a tool are interested in whether it is possible to buy nozzles of smaller diameters. You should be prepared for the fact that equipment of this kind does not provide for the availability of such an opportunity. You may be faced with the fact that the air from the nozzle flows constantly. In this case, as consumers assure, the tool is not working, you should contact a service workshop for help.
Reviews about the pistol "Kraton"
AHG-02G brand model will cost the consumer 2,300 rubles. The equipment operates at a minimum pressure of 3 bar. The volume of the tank is 6 liters, which, according to users, increases the amount of work carried out. The equipment is equipped with a five-position calibrating plate, which allows you to set the desired hole diameter depending on the material used. Buyers note that the presence of a ring wrench eliminates the need to purchase additional interchangeable tools. Along with the device, a hex wrench is also supplied, which is not always possible to find in the set of analog options.
Making a plaster gun
If you decide to make a plaster gun with your own hands, then you should familiarize yourself with the principle of its work. Air escaping from the nozzle will entrain particles of the mixture, spraying them onto the wall. The capacity is a bucket, with which the master will be able to collect plaster from another capacity. The front inclined wall of the tool allows you to apply the composition to both vertical and horizontal planes. In the latter case, we can talk about the ceiling. For the reason that the plaster has significant weight, it is best to use Rotband mixtures to apply the composition to the ceiling. This will contribute to the closed part of the top cover of the tank. If you decide to make a plaster gun, it is best to observe the approximate nozzle dimensions and the pitch between it and the hole in the front wall of the bucket.
The diameter of the nozzle can be from 4 to 5 mm, while the distance to the front wall can vary from 15 to 20 mm. The diameter of the front hole is most often equivalent to 10-13 mm. The bucket can be made from a five-liter rectangular canister of solvent. However, the front wall is recommended to be made of galvanized steel. Connections can be made with blind rivets.
Methodology
You can borrow a drawing of a stucco gun from an article or do it yourself. We recommend using a ready-made gun, which is intended for pneumatic devices, as a valve and a handle. Its front part should be fixed with a thread, and the gun will be fixed in the hole that you will make in the hopper. It should be noted that the weight of the solution will be decent, and the gun is made of thin aluminum. Therefore, it should additionally be fixed with two strips of duralumin. It is necessary to attach a handle to the bunker, the angle of its location should be 45 degrees. If you are left-handed, then it should be placed on the appropriate side.
