In repairs, mounting foam is very popular, and all due to the fact that it makes it possible to quickly fill the cavities of the space during the installation of windows or between any building materials. Polyurethane foam, by its properties, is an instantly hardening, airtight substance.
It perfectly prevents the appearance of cracks and is suitable for fixing elements in construction. She has only one drawback, after opening the cylinder and starting to use it, the foam treacherously freezes in the valve, thereby creating problems in the further use of the product. It turns out that the purchased cylinder must be used completely, without residue. The way out is to buy a special gun designed for mounting foam.
Modern cylinders have a threaded base that is easily screwed onto the gun. The tool perfectly doses the foam supply, the seams are aesthetic and without excess funds. Once you've tried a pistol, you won't want to give it up.

As a rule, the use of mounting foam from a cylinder will cost more money (even with infrequent use) and will be significantly inferior in quality to work performed with a gun. The tool is not so expensive and quickly pays for itself, the main thing is to make a good purchase so that later you do not have to regret the money spent. And for this it is worth studying the selection criteria.
The main selection criterion is the reliability of the device. All parts of the tool should preferably be made of metal, but it has its drawbacks, and the main one is heaviness, but it will last relatively longer than a product made of plastic or a powder mold. It would be better if the device can be disassembled, as this will facilitate the process of cleaning or repair. In addition, if any part breaks, it can be replaced with a new one without any problems. You will also need to pay attention to the quality of the two valves.
The next points to focus on are the length of the barrel and the flow regulator.
The length of the barrel is in three ranges: from 10 to 15 cm (suitable for working on accessible surfaces), from 15 to 20 cm (universal length, suitable for any work) and more than 20 cm (the tool is suitable for working on hard-to-reach surfaces).
Regarding the flow regulator, if the gun is without it, then it will not allow you to save mounting foam. For the price, such a model, of course, is cheaper than its "brothers". There are pistols that have a plastic regulator in their functionality, but it is extremely unreliable, since continuous operation easily disables it. The best tools are those that have a Teflon or metal ball.
Dozens of different companies produce repair and construction tools. Among them, leaders from European brands stand out: Kraftool, Matrix, Stayer, Atoll and Hilti.
The German Kraftool creates a variety of series of pistols for every taste and budget. For example, the Kraft-Max series is known for having a Teflon-coated working surface, while the Industrie series has a brass needle valve and a metal barrel with a body.
Matrix has long gained popularity in our market and became famous for its impeccable quality. All the necessary tests are carried out perfectly and there is no doubt about the reliability of the purchased products.
Before the work process, you need to carefully check the tightness of the threaded connections. Shake the foam bottle thoroughly, then remove the cap and screw the gun to the bottle. On the edge of the gun, where the handle is located, there is an adjusting screw, it will need to be turned to the left a quarter of a turn. Now you can press the trigger, the gun will begin to fill with foam. Adjustment (exit) of the foam is carried out using a screw. It is not necessary to fill the entire seam with foam, as it has the ability to expand. Therefore, the filling should be 40 percent of the estimated volume of the seam.
After the work is completed, the adjusting screw is tightened to the stop. If there is still foam in the balloon, then you do not need to unscrew it. The foam in the gun must be under pressure, otherwise it will begin to dry. But you need to remember that for more than 3-4 days the gun should not be filled with foam, as it will thicken.
For any repair, whether at home, in the country or at work, you will need to use mounting foam.
