How to choose an electric gun for sealant?

In the course of repair and construction work, you may encounter the need to use sealant. Sealing substances can be different, but the main difficulty in their use is that it is not very convenient to work with them without a special gun.

The electric pistol is designed to greatly facilitate the process of applying the composition. The seam at the same time visually becomes clearer and more accurate. Any model of the device will necessarily consist of a piston rod and a housing. These two elements are responsible for the uniform flow of the substance to the surface. The trigger serves to control the extrusion of the sealant.

The electric gun has the following advantages:

• high power;
• savings in sealant consumption;
• seam accuracy;
• comfortable and lightweight design;
• acceptable cost.

If you follow the correct sequence of actions, then Difficulties in working with electric gun will not be detected.

1. The first thing to do is to prepare a container with a sealant. The nose is cut at an angle of 45 degrees. Experts strongly recommend not to make the hole too large for the first working experience. After the initial skills are obtained and there is an idea of ​​the rate of supply of the composition, the hole can be made a little wider.
2. The second is the preparation of an existing model of a pistol. As a rule, it is enough to loosen the locking nut and pull the stem all the way. Next, you need to install a tube with a sealant and securely fix it, securing the previously relaxed parts.
3. Work surface treatment is standard cleaning and degreasing for better adhesion of the composition and its durability.
4. Application and filling of the seam - this work will be done by the electric pistol itself.The worker is only required to gently move it along the intended working space.

The choice of model depends on where and by whom it will be applied, it is worth thinking about this before going to the store.

1. The first thing you should pay attention to is, of course, the absence of damage. It is unacceptable that cracks, chips and other defects are present on the body of the gun.
2. The gun should be comfortable in the hand, to be quite light and not slippery.
3. The body material can be steel (for the sealant in the cartridge package) or aluminum (for the tubes).
4. Typically, for home use, 280 ml cartridges are used. Tubes are designed for a wider scope of work and are used by professional builders.

1. Volume Depending on the model, the installation volume can vary from 280 ml to 600 ml. Perhaps you should pay attention to the tool that can adapt to most popular tubes of different sizes.
2. Power. The more often you plan to use a gun and the wider the range of construction works, the higher should be its power. Practice shows that the power of 18 watts is able to cope even with an impressive load.
3. Type of food. Electric guns are able to work both directly from the network of 220 V and from the battery. The second option is preferable for most masters. It should be borne in mind that often the battery is not included in the basic kit with the purchase and must be purchased separately.
4. Feed rate sealant depends on the power of the tool. It is calculated in mm / s or g / s. There are models that can adjust the speed, for example, 1-5.5 mm / s.

The most popular manufacturers who have earned the trust of the consumer: Metabo, Makita, Skil.

Products of domestic manufacturers differs in more reasonable price, at the same time only slightly conceding to the foreign analogs in the main characteristics.

• Models brand "Enkor" earned the trust of the masters with their ability to work even with very viscous substances;
• "Caliber" - one of the most popular models among Russian consumers due to ease of operation and robust case;
• Electropist "Bison" It is also a reliable tool, presented in a wide range of models.
