Pneumatic gun for sealant: selection criteria

Often when carrying out sealing it is difficult to do without a special tool. Among the similar auxiliary equipment offered in the modern construction market, the pneumogun is most popular with professional builders. It is important to examine what constitutes this tool in order to choose the right version for sealant.

What it is?

Pneumatic gun for sealant is a device for accurate and uniform distribution of the hermetic composition during repair work. Externally, this is a simple design with space for sealant in the package. This device is designed to simplify the manual labor and physical effort of the master.

It allows you to work as efficiently as possible, using special liquid sealants to seal gaps and cracks. They are available in metal and plastic tubes. A pneumatic pistol is equipped with a valve, by means of which excess sealant is discharged, thereby eliminating the overrun of the mixture. The tool is suitable for different containers and facilities.

Special features

Air gun for sealant different closed type. This is a professional tool with a compressor, it is simple and easy to use. Work is carried out by means of pressure of compressed air. Sealant is distributed from the tube when the master presses the trigger.

The uniformity of the applied layer is caused by a continuous and uniform supply of liquid sealing agent. The best sealant for this device is a composition based on acrylic and polyurethane.

Unlike other analogues, this tool is equipped with an air supply adjustment system. Compared with other devices, it is more reliable, it differs in the speed of applying a sealant, the uniformity of the applied layer.Most models are made of metal, which allows, if necessary, insert material into the gun not only in hard but also in soft packages.

The convenience of this device due to the lack of need for regular refueling. Its scope of application is extensive: in addition to the construction, a pneumogun is used in industry and everyday life.

Advantages and disadvantages

The reason for the demand for sealant is the weight of the advantages of a pneumatic pistol for this composition.

Its main advantages are:

  • universality;
  • seam accuracy;
  • accuracy of application of the composition;
  • frame strength;
  • rust resistance;
  • resistance to mechanical damage;
  • ease of use;
  • small operational expense;
  • lack of marriage in work;
  • durability.

In addition, the advantage of this gun is the fact that the model can have a housing for the mixture, which is prepared independently at home. She allows to work with not packed up sealants. Despite the external complexity of the system, even a beginner can work with it. The quality of work will be quite high.

Since the risk of failure of this device is small, it lasts for a long service life. With a lot of advantages, this device is not portable. It is inconvenient to transport. However, this is the only drawback can not be called essential against the background of all advantages.

How much does it hold?

This gun is unique because it can hold a different amount of sealant. That is, mixtures of different volumes will do for him. Some models are able to accommodate cans with a capacity of 0.5 to 1.5 liters. Some varieties are rated for a volume of 600 ml. This feature eliminates the need for frequent refueling of the gun, which is an important factor when carrying out a large amount of work performed.

How to fill up?

After buying a pneumatic gun for sealant, many have a question about its proper use and self-refueling.

Consider the subtleties of refueling and use: it depends on how well the processed seam will turn out.

  • Before you insert a tube with a sealant in the gun, you must take a cartridge (vial), open it with a construction knife, put on the cap and cut off its tip at a 45 degree angle.
  • The width of the cut must be equal to the thickness of the seam that you plan to fill.
  • If you are using sealant for the first time, make sure that the diameter of the hole being cut at an angle is small.
  • If the cartridge is made of plastic, the exit opening can be pierced. However, in some cases this may contribute to an increase in the resistance of the extruded sealing compound.
  • It is necessary to insert the cartridge (tube) into the body gun and fix it with a threaded end.
  • It is recommended to unscrew one of the plugs to refill the composition in a soft package, after which the tube should be placed in the case and the applicator put on.
  • After using the composition, it is necessary to close the cap.
  • If in the process of work the tip of the gun got dirty, try to erase the composition from it immediately, using a solvent for this purpose. If the sealant completely hardens, it will have to be mechanically removed from the gun, but this will be problematic.

How to choose?

On the construction market there is a wide variety of such equipment, including excellent brand devices. However, the choice of this gun is not as difficult as it may seem.

It is necessary to take into account the main selection criteria, it will allow you to choose a quality product with good performance indicators.

  • The choice of design depends on the type of tasks. Professional device copes with different jobs. However, if you need a one-time sealing of seams, there is no point in buying a professional tool.
  • If the product is purchased not for a one-time job, you need to hold it in your hands when purchasing to evaluate the case: it should be light, because the extra weight can affect the quality of the seam.
  • The device should be comfortable. Also appreciate the reliability of the device, because you have to work with a gun more than once.
  • It is necessary to pay attention to the trigger. During the work should not feel the tension. It is important that defects in the course of the device be excluded.
  • Ask the seller what the hook is made of. For the purchase of the ideal option with a piece of molded aluminum.
  • Rate the quality of the product. It should not be chipped, chipped, scratched or other visible defects.
  • It is necessary to take into account that a good instrument has different regulators and limiters.This is a branded card of respected brands in the construction segment.
  • It is better to choose models whose body is made of metal.
  • Keep in mind that good tools usually do not sell at great discounts. Such products differ in cost, adequate to their quality and durability.
  • Purchase should be carried out in a trusted store with a positive customer rating.
  • It is necessary to evaluate the operation of the piston and the ability to adjust the force of its pressure, as well as pay attention to the quality of the connections of the body of the product.
  • Do not forget, a pneumatic gun for sealants allows you to adjust the amount of air, which allows you to distinguish it from other analogues.
  • When buying, you should ask for a certificate of product quality and its compliance with safety standards. Trademarks that value their reputation always supply their goods with similar documentation.

It is important to consider one nuance: The type of gun in question is characterized by its closed appearance. This is a cylindrical model with a handle. The cylinder follows the shape of a tube or a cylinder, due to which the sealant inside it is held securely.If you see that the structure is open, this device is not pneumatic.

Also pay attention to the cost. Quality models of famous brands are not cheap. This is due to the fact that they belong to the professional equipment for construction work. The price of such products sometimes reaches 20,000 - 35,000 rubles. However, it pays off with reliability and convenience. Budget options cost about 9000 - 10,000 rubles.

What else to consider?

When buying a gun, choose a model that will be convenient for use. It is important to consider the volume for which the tool is designed. If it is important for a professional master that the device interferes with a maximum of sealant, then a 600 ml model will be enough for household work. This is due to the fact that not everyone will use a pistol regularly, and a sealant with a long stay in the pistol may lose its properties.

You should not get the most expensive option, because if the product is not used constantly, it loses its operational properties. It is better to choose an option at an average price, which will be enough for domestic needs.Be sure to ensure the safety of the design, choosing a model in the store.

Reviews

Pneumatic gun to spray sealant is considered a convenient tool in the field of large and small construction. This is evidenced by customer reviews and professional craftsmen. Air gun for suture sealing can be used on different bases (from wood to double-glazed windows). Masters mark varieties designed for 600 ml. They write that the cylinders do not weigh down the weight of the tool, and this amount is enough to handle cracks and fill cracks.

Buyers appreciate the fact that this tool allows you to do a do-it-yourself seal.without the help of professional craftsmen. At the same time, a homemade seam is no different from those performed by professionals. According to those who used these devices, the valve does not allow overflow of the composition, which allows to avoid overruns, thereby saving sealant.

Some in the reviews note the practicality of the models of the combined type of plastic and aluminum. However, others comment in the reviews that metal is the best for the case.

Which brands to prefer?

Customers especially like Wilton and Workman products. The material feed in them is carried out smoothly and continuously, which is important for performing a smooth seam. At the same time, the operation of the adjusting mechanism is simple and safe, so the risk of injury is eliminated during operation. Ergonomic handle, three adjustment functions, minimal residual output - not all the advantages of these devices.

Products are able to work with adhesive compositions. The tube is compressed by a floating plunger assembly, which is fixed to the back cover by means of a special reinforced polyester cord. For the accuracy of the application in these models meets the trigger valve. The outlet valve is responsible for the minimum flow rate of the secondary sealant output.

These models are made of lightweight aluminum and plastic. Convenience of tools is considered the possibility of additional purchases of nozzles that are suitable in size.
