Which sealant gun should you choose?

For recurring simple tasks, such as repairing joints in a bathroom or renovating furniture, for example, a conventional household pistol with a mechanical sealant feed is suitable.

When choosing such a model, you should pay attention to the possibility of its work with small packages of sealant. It is desirable to support exactly the 310 mm tube, as the most common and demanded

It is desirable to support the 310-mm tube, as the most common and demanded.

So that an inexpensive pistol purchased for a home does not fail after several operations, it is better to look towards reinforced structures with a steel thickness of at least 2 mm.

It is important to remember that you cannot apply a neat seam without using a gun, so you will have to buy this tool anyway. If you need to do any one-time job, you can get by with the cheapest half-body "Chinese", which will be enough for a maximum of 3 refueling

The choice of a pistol for professional activity is primarily based on the following criteria:

Convenience of transferring the instrument to a certain operating mode, for example, from tubes to packages.
Long service life, that is, reliability.
Weight that plays an important role in intensive work.
Down pressure.
Warranty service.

Of course, professionals try to buy mostly battery models, since they have high power, do not require physical effort when using.

Such options are capable of working on a single charge for an average of 3 hours, and weigh about 2 - 3 kg, depending on the model.

If you plan to work with bulk sealant, attention should be paid to pneumatic self-priming guns

Closed sealant guns

Choosing a sealant gun is sometimes a real challenge. You need to purchase exactly the option that is ideal for construction and renovation work. They can be semi-hull, skeletal, tubular, and also differ in volume and functionality. Professionals choose closed cases.

Appearance

A closed sealant gun is considered universal. It is for this reason that professionals love him. It is also often referred to as a syringe. It has a closed body and a piston with a trigger for extruding material. The body can be aluminum, steel, glass or plastic.

To improve the convenience of work, you can additionally purchase:

various attachments to facilitate work in hard-to-reach places;
backlit nozzle;
a cleaning needle;
punch designed to remove the frozen mixture.

There are additional functions in professional pistols:

for fixing the trigger during prolonged work;
to protect against leakage;
for adjusting the extrusion speed, which is very helpful in works that require high precision.

Peculiarities

Full-body pistols have a number of features, thanks to which they are chosen by builders:

fully closed housing with a reliable base;
the ability to relieve pressure, which eliminates the leakage of the sealant, which creates a lot of inconvenience;
filling the pistol with sealant can be done manually, from the container in which it was mixed;
complete with a gun, they sell nozzles (spouts) for more convenient use;
the professional gun holds from 600 to 1600 ml of the sealant, which significantly reduces its need for refueling.

Application

Full-body pistols are filled with both plastic tubes with sealant and sealing compounds in soft packaging. Sealants that must be mixed before use, or prepared on their own, can also be filled into such pistols.

The work procedure is quite simple.

Preparation. On the tool, you need to unscrew the nut fixing on top and remove the nose, and the stem is also pulled back all the way back. At this point, the remnants of the sealant from previous work should be removed.
Refueling. In plastic tubes, the tip of the spout is simply cut off and inserted into the body. If you have a sealant in a soft package, you will need to remove one of the metal plugs with side cutters and also insert it into the gun. You can fill the tube with a spatula with a freshly prepared sealant, or suck it out of the container like a syringe.

Job. The sealant is squeezed out into the seam by pressing the trigger of the gun. If it is necessary to suspend work, and the tool is mechanical, then you need to move the stem back a little, this will help to avoid arbitrary leakage of the paste. The sealing material should be applied evenly, completely filling the seam.
Treatment. After completion of the work, if necessary, the seams are rubbed with a rubber spatula or sponge.
Following actions. If you used a plastic tube and there is still sealant in it, then close the spout with the appropriate cap. Remains of sealant from soft packaging or freshly prepared composition must be removed. You also need to remove drops of the composition accidentally hitting the body. Once the sealant has set, it is extremely difficult to remove, which can render the instrument unusable.

Purchase

The price rating depends on the size of the body, brand and type of pistol. The tool of the Japanese brand Makita costs an average of 23 thousand rubles, and the Soudal brand already 11 thousand. Their volume is 600 ml. A similar version of the English brand PC Cox costs only 3.5 thousand rubles. But the components for it will have to be purchased separately. But pistols of the Zubr brand will cost you around 1000 rubles with all the accessories.
