A polyurethane foam gun is one of the most essential repair tools. The foam itself is a dense mass in a cylinder under pressure and allows, for example, to fill the space between wall openings or is used when installing windows. This substance quickly hardens and prevents the appearance of cracks due to its tightness. But also the foam has excellent thermal insulation properties, moisture resistance, strength and non-toxicity. All these characteristics are simply irreplaceable in construction.

A large number of pistol brands and models are represented in this market segment. The article will focus on the popular Hilti brand.

Device

To work with a pistol, you need to know its structure, this will help not only be confident in the chosen model, but also ensure correct operation without breakdowns.

The construction of a gun for polyurethane foam is quite simple and straightforward:

  • The barrel of the device is a tube, at its ends there are special valves that ensure the main task of the pistol by creating high pressure. It is this that promotes the outflow of foam. The barrel itself is covered with Teflon, is collapsible in this model and consists of two parts.
  • For ease of use, there is a handle (in the Hilti CF DS-1, it is ideal for the largest hand) or a central support for the entire tool. On it there are special recesses for the fingers, which makes it easier to work. In this model, it is also anti-slip.
  • The holder for fixing the balloon, in other words - a universal adapter. This part of the device has the greatest load. It is suitable for a variety of cylinders, even the production of other factories.
  • A trigger or adjustment lever that allows you to control the amount and flow rate of the foam used.
  • And also there is a fastening part of the pistol, it is responsible for the location of the cylinder. As a rule, it is made in the form of a nut, and thanks to it, you can remove the barrel.

The principle of operation of the equipment itself is quite simple, and anyone can handle it, even the one who first picked up a pistol.

  1. Place the cylinder with the valve facing up onto the adapter. There should be a hissing sound.
  2. The adjustment screw must be turned counterclockwise to check and press the adjustment lever in order for the mass to begin to flow.
  3. After that, it is worth checking the consistency of the foam.
  4. The work surface must be moistened with water, so the foam will harden better.
  5. The foam is applied in layers, evenly, and the tip of the gun must be completely immersed in the material during operation.

  2. instead of it, a cylinder with a cleaner is installed;
  3. in this state, you need to leave the pistol for about 15 minutes;
  4. the cleaning fluid is released using a lever and the can is removed.

To disassemble the tool, you must first unscrew the nose. This can be done with pliers or a wrench. Next, the tube is unscrewed in the same way. If you need to remove the front cover from the feed barrel, then you need to use a screwdriver and then carefully unscrew the barrel itself.
