Which foam gun to choose: rating of the best models for easy use

In modern construction, polyurethane foam has become a very popular material. It is used to fill voids, install windows and doors, and create insulation. Thanks to adhesion and rapid hardening, it is possible to speed up work of varying complexity. To economically and evenly apply the unruly sticky mass, a special gun was invented. These devices are found in abundance on the shelves of hardware stores, and choosing a decent option is not always easy. To help you, we have compiled a rating, which includes only the best models of amateur and professional-class polyurethane foam guns.

No. 5 – VORTEX 73/3/6/4

Price: 890 rubles

The device from a domestic company was included in our selection not because of patriotic feelings. Unlike the previous competitor, the model has an extremely reliable plastic handle that provides a secure grip. Thanks to it, the gun does not slip out of your hands during operation. The design is lightweight - only 400 grams, so you can use it for a long time.

Considering how much a pistol costs, it is foolish to expect it to be able to perform professional volumes of tasks. In this mode it will quickly fail. But for work in amateur mode it is perfect. In addition, you can use it in hard-to-reach places due to the long nose of the pistol.

Features of selection and use of the device

Housing material

Tool materials include different compositions of plastic and metal. The significant presence of the former makes it lighter and cheaper. Devices in the low price segment are more suitable for beginners: you don’t mind ruining them if something happens. But there are also expensive models made of impact-resistant plastic and stainless steel.

Metal pistols are significantly heavier than plastic ones. In the process of their production, aluminum, brass, and the following alloys are used:

• Copper-zinc-aluminium. Tools made from it are characterized by minimal weight and are designed for a long period of use.
• Aluminum-silicon. The reliability of a silumin case largely depends on the honesty of the manufacturer.

When thinking about which foam mounting gun to buy, it is important to focus on the availability of the cleaning procedure. Expensive devices are often coated with Teflon. Traces of polyurethane foam are easier to remove from the latter. But you should always remember: the Teflon coating can be easily damaged. Therefore, you should be extremely careful during the cleaning process.

Thanks to the smooth surface, the stainless steel tube is easy to clean. If it is made of plastic, then the tool should be cleaned immediately after completion of work. For high-quality washing, it is recommended to use special products.

No. 7 – Kraftool PROKRAFT 0685_z03

Price: 1,200 rubles

Our top moves on. Kraftool PROKRAFT 0685_z03 is an ergonomic, almost perfect pistol. Its trigger does not require strong pressure from the owner, which has a positive effect on ease of use. The gun features an innovative dual O-ring design and precision machined needle valve to ensure a reliable seal.

The cylinders and nozzles are coated with PTFE Teflon, making the tool easier to maintain. The two-component pistol handle does not slip in the hand, which contributes to comfortable work. The barrel, polished from the inside, prevents the foam from hardening inside the gun. Having analyzed the reviews of the owners, we did not find any significant flaws.

How to use

Before the work process, you need to carefully check the tightness of the threaded connections. The foam container must be shaken thoroughly, then the cap must be removed and the gun screwed to the bottle. At the edge 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 lever, the gun will begin to fill with foam. Adjustment (output) of foam is carried out using a screw. There is no need to fill the entire seam with foam, as it has the ability to expand. Therefore, the filling should be 40 percent of the expected volume of the seam.

After the work is completed, the adjusting screw is tightened until it stops. If there is still foam in the container, there is no need to unscrew it. The foam in the gun must be under pressure, otherwise it will begin to dry out. But you need to remember that the gun should not be filled with foam for more than 3-4 days, as it will thicken.

Leading manufacturers

The construction market is represented by dozens of companies specializing in the production of guns for polyurethane foam. The segment is divided into expensive and budget items for one-time use.

Tips for choosing

When choosing, you need to pay attention to the following points:

• How comfortable is it to hold the device in your hand?
• Possibility of regulating the supply.
• Material (it is better to choose metal).

• For the length of the barrel (the longer, the deeper the cracks are available for foaming).
• The weight of the gun should be as small as possible so as not to load the hand.

Cheap models are usually intended for one-time work. They are made of plastic, and it is impossible to disassemble and clean them. Professional products are already made of metal; the handle is necessarily covered with rubber and abrasive particles for convenience. This pistol can be easily disassembled, it fits perfectly in the hand and does not strain the hand. Only the price will be noticeably higher.

Principle of operation

Before you start, you need to familiarize yourself with the basic principles of using the gun:

• Before installing a new cylinder, you should check the adapter for cleanliness: remove, if necessary, any remaining foam from the previous cylinder, remove dust. The valve ball should be clearly visible.
• The balloon itself must be placed on the floor for a couple of minutes so that the mass settles to the bottom. Without lifting it, place the gun on top: winding is done evenly, distortions are excluded. After opening the built-in valve, it is easy to press the lever: if gas begins to escape, then the device is ready for use.
• Before applying to the main area, you should try to apply a small amount of mass on an inconspicuous part. This is necessary to adjust the feed and set the desired output speed.
• Horizontal filling can be done in any direction, and vertical filling can be done from bottom to top.

No. 3 – Sibrtech 88677

Price: 620 rubles

The pistol has an unusual barrel shape - narrowed towards the edge and elongated. Due to this, with its help you can carry out sealing in the most inconvenient places. The solution is designed in such a way that you can completely disassemble it and easily replace broken parts. This can also be done for the purpose of washing and cleaning, and even an inexperienced user will not experience any problems with it.

The device has a ratchet mechanism that guarantees an accurate dosage of foam. Threaded connections are made of metal. The last point is worth paying special attention to, since there is a model on sale with similar markings, but with plastic elements. For the home craftsman, the gun is an ideal solution without significant disadvantages.

No. 10 – Kraftool SUPER-KRAFT

Price: 2,000 rubles

Inexpensive but good model, common in Russia. Users appreciate it for its smooth adjustment of the needle-type valve stroke. Thanks to it, you can achieve the required foam consumption, significantly saving on material. In addition, the valve is made of reliable materials - Teflon-coated brass, and the body, in turn, is made of durable metal. This combination is rare to find in pistols of this price.

We also note the fact that the anti-adhesive coating prevents foam from adhering to the metal components of the product, such as the nozzle, valve and holder. The downside is that it doesn’t disassemble for cleaning as easily as we would like.

Where are they used?

The device is used to perform the following types of work:

• Noise and sound insulation.
• Filling voids in various structures.
• Ensuring the tightness of joints.

• Carrying out installation work (connecting materials, fastening polystyrene foam, roofing work, etc.).
• Insulation of buildings and structures (windows, doors, roofing).

Expert opinion

Torsunov Pavel Maksimovich

Instead of a gun, a regular can of foam is sometimes used, but in practice the material consumption will be greater, despite the low price of the cans. Therefore, it makes no sense to consider this option.

No. 6 – STAYER Professional BlackPRO

Price: 800 rubles

A popular model in Russia from a Chinese brand. The love of our compatriots for it is due not only to its affordable price tag. The fact is that the gun comes with an attachment for hard-to-reach areas of the seam, which can often be found in the equipment of more expensive new models. In budget models, the trigger area often suffers, but here it is not flimsy and will definitely not fail after an accidental fall.

In terms of build quality, everything is ambiguous. As is often the case with Chinese devices, it is a lottery device. If you come across a model without defects, it will be able to satisfy your amateur needs, otherwise it will fail after the second or third run. The main drawback really surprised us. It turned out that users in reviews most often complain about the extremely uncomfortable handle.
