Sealant Air Gun: Selection Criteria

Often, when carrying out sealing, it is difficult to do without a special tool. Among such auxiliary equipment offered on the modern construction market, a pneumatic gun is more popular with professional builders. It is important to study what this tool is in order to choose the right option for your sealant.

The air sealant gun is a device for accurately and evenly distributing the sealant during repair work. Outwardly, this is a simple design with a place for the sealant in the package. This device is designed to simplify manual labor and physical efforts of the master.

It allows you to carry out the work as efficiently as possible, using special liquid sealants to seal cracks and cracks. They are available in metal and plastic tubes. The pneumatic pistol is equipped with a valve through which the excess sealant is dumped, thereby eliminating over-consumption of the mixture. The tool is suitable for a variety of containers and media.

The pneumatic sealant gun is of the closed type. This is a professional compressor tool, it is simple and convenient to operate. The work is carried out by means of compressed air pressure. The sealant is dispensed from the tube when the master pulls the trigger.

The uniformity of the applied layer is due to the continuous and uniform supply of the liquid sealant. The best sealant for this device is a compound based on acrylic and polyurethane.

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

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

The reason for the demand for sealant is considered to be the mass of advantages of a pneumatic gun for this composition.

Its main advantages are:

• versatility;
• the accuracy of the seam;
• the accuracy of applying the composition;
• frame strength;
• rust resistance;

• resistance to mechanical damage;
• ease of use;
• low maintenance cost;
• lack of marriage at work;
• durability.

In addition, the advantage of this pistol is the fact that the model can have a housing for a mixture that is prepared independently at home. It allows you to work with bulk sealants. Despite the external complexity of the system, even a beginner can work with it. At the same time, the quality of work will be quite high.

Since the risk of breakage of this device is small, it is enough 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 that cannot be called significant against the background of all the advantages.

This gun is unique in that it can hold different amounts of sealant. That is, mixtures of different volumes are suitable for him. Some models are capable of accommodating cans with a capacity of 0.5 to 1.5 liters.Some varieties are designed for a volume of 600 ml. This feature eliminates the need for frequent refueling of the pistol, which is an important factor when carrying out a large volume of work performed.

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

Consider the subtleties of dressing and use: it depends on how high-quality the processed seam will turn out.

• Before inserting the sealant tube into the gun, you need to take the cartridge (bottle), open it with a construction knife, put on the cap and cut off its tip at an angle of 45 degrees.
• The cut width should be equal to the thickness of the joint you plan to fill.
• If this is your first time using gun sealant, keep the diameter of the beveled hole small.

• If the cartridge is made of plastic, the outlet can be punctured. However, in some cases, this can contribute to an increase in the resistance of the extruded sealant composition.
• It is necessary to insert the cartridge (tube) into the body gun and fix it with a threaded tip.
• For filling the composition in soft packaging, it is recommended to unscrew one of the plugs, after which the tube must be placed in the body and the applicator put on.
• After using the composition, it is imperative to close the cap.
• If the tip of the gun gets dirty during work, try to wipe off the composition immediately using a solvent for this purpose. If the sealant hardens completely, it will have to be removed from the gun mechanically, but this will be problematic.

There is a wide variety of similar equipment on the construction market, including excellent branded devices. However, the choice of this pistol is not as difficult as it might seem.

It is worth considering the main selection criteria, this will allow you to choose a quality product with good performance.

• The choice of design depends on the type of task at hand. A professional device can handle a variety of jobs. However, if you need a one-time sealing of seams, there is no point in buying a professional tool.
• If the product is not purchased for a one-time job, when buying it you need to hold it in your hands to evaluate the case: it should be light, because excess weight can affect the quality of the seam.
• The device should be comfortable. Also appreciate the reliability of the device, because you will have to work with the pistol more than once.

• It is necessary to pay attention to the trigger. No tension should be felt during work. It is important that defects in the movement of the device are excluded.
• Ask the seller what the hook is made of. For purchase, the option with a molded aluminum part is ideal.
• Evaluate the workmanship of the product. It should be free of chipping, chips, scratches and other visible defects.
• It should be noted that a good instrument has different controls and stops. This is the brand card of the respected brands in the construction segment.
• It is better to choose models with a metal case.

• It should be borne in mind that good tools usually do not sell at large discounts. Such products differ in cost adequate to their quality and durability.
• The purchase should be made in a trusted store that has a positive customer assessment.
• It is necessary to evaluate the operation of the piston and the possibility of adjusting the force of its pressure, as well as pay attention to the quality of the joints of the product body.
• Do not forget, the air gun for sealants allows you to adjust the amount of air, which makes it possible to distinguish it from other analogues.
• When buying, you should ask for a certificate of product quality and its compliance with safety standards. Reputable brands always supply their products with such documentation.

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

Also pay attention to the cost. Quality models from well-known brands are not cheap. This is due to the fact that they are professional equipment for performing construction work. The price of such products sometimes reaches 20,000 - 35,000 rubles. However, this pays off in reliability and convenience. Budget options cost about 9,000 - 10,000 rubles.

When buying a gun, choose a model that will be convenient for use. It is also important to take into account the volume for which the instrument is designed. If it is important for a professional craftsman that the device intervenes 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 the gun regularly, and the sealant may lose its properties if it is in the gun for a long time.

You should not purchase 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 sufficient for domestic needs. Be sure to consider the safety of the design when choosing a model in a store.

The sealant air gun is considered a handy tool in the construction industry, both large and small. This is evidenced by reviews of buyers and professional craftsmen. The air gun can be used on a variety of substrates (from wood to insulating glass). Craftsmen note varieties designed for 600 ml. They write that the cylinders do not make the weight of the tool heavier, but this amount is enough to handle cracks and fill cracks.

Buyers also appreciate the fact that this tool allows you to do it yourself.without the help of professional craftsmen. At the same time, a homemade seam does not differ from those performed by professionals. According to those who used these devices, the valve does not allow excess composition to flow out, which makes it possible to eliminate overruns, thereby saving the sealant.

Customers especially love products from Wilton and Workman. The material is fed into them smoothly and continuously, which is important for making an even seam. At the same time, the operation of the adjustment mechanism is simple and safe, therefore, the risk of injury is excluded during operation. Ergonomic handle, three adjustment functions, minimum residual output - these are not all the advantages of these devices.

Products are capable of working with adhesives. The tube is compressed by a floating plunger assembly, which is secured to the back cover by means of a special reinforced polyester cord. The release valve is responsible for the accuracy of application in these models. The outlet valve is responsible for the minimum flow rate of the secondary sealant outlet.

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