8 best polyurethane foam guns in 2024

In the repair, 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. By its properties, polyurethane foam is an instantly solidifying, hermetic substance.

It perfectly prevents the appearance of gaps and is suitable for fixing elements in construction. She has only one drawback, after opening the balloon and starting to use it, the foam treacherously solidifies 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 a remainder. The way out is to buy a special gun designed for polyurethane foam.

Modern cylinders have a threaded base that can be easily screwed onto the gun. The tool perfectly dispenses foam, the seams are aesthetically pleasing and without excess product. Having tried working with a pistol once, you will no longer want to give it up.

How to choose

As a rule, using polyurethane foam from a cylinder will cost more money (even with infrequent use) and will be significantly inferior in quality to the work performed with a pistol. The tool is not so expensive and quickly pays for itself, the main thing is to make a good purchase so that you do not have to regret the money spent later. 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 comparatively longer than a product made of plastic or a powder mold. It will be best if the device can be disassembled, as this will facilitate the cleaning or repair process. In addition, if any part breaks, then 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 barrel length and flow control.

Barrel length comes in three ranges: from 10 to 15 cm (suitable for working on accessible surfaces), from 15 to 20 cm (universal length, suitable for any job) and over 20 cm (tool suitable for working on hard-to-reach surfaces).

Regarding the flow regulator, if the gun is without it, then it will not allow saving polyurethane foam. For the price, such a model is, of course, 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 with a Teflon or metal ball.

Top manufacturers

Dozens of different companies make repair and construction tools.Among them are leaders from European brands: Kraftool, Matrix, Stayer, Atoll and Hilti.

German Kraftool creates various series of pistols for every taste and budget. For example, the Kraft-Max series is known for having a Teflon coated surface, while the Industrie series has a brass needle valve and metal barrel with 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.

How to use

Before the working process, you need to carefully check the tightness of the threaded connections. The foam bottle must be shaken thoroughly, then the cap must be removed and the gun screwed onto the bottle. At the end of the gun, where the handle is located, there is an adjustment screw, it will need to be turned to the left a quarter turn. Now you can press the trigger, the gun will begin to fill with foam. Adjustment (outlet) of the foam is carried out with a screw. It is not necessary to fill the entire seam with foam, since it has properties to expand. Therefore, the filling should be 40 percent of the estimated seam volume.

After the work is completed, the adjusting screw is tightened until it stops. If there is still foam in the cylinder, then you do not need to unscrew it. The foam in the gun must be under pressure, otherwise it will dry out. But you need to remember that for more than 3-4 days the gun should not be filled with foam, as it thickens.
