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.

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.
