Features of the

In the process of installing door frames, as well as PVC windows (metal-plastic models), you cannot do without the use of polyurethane foam. Professionals say that it is very difficult to apply the product by hand. Special equipment allows for installation as soon as possible. Specialized shops offer a wide variety of different instrument models for practical and convenient use of the composition. Foam cylinders themselves have distinctive characteristics.

Despite the rich assortment, most types of products are versatile. That is, almost all cylinders produced are suitable for most pistols.

When working with foam, be sure to think about personal safety.… Pros strongly recommend wearing gloves and protecting your eyes with construction goggles.

You should also carefully study the instructions for using the product, especially if you do not have proper experience in handling it.

Varieties of material

Before proceeding to the description of the process of using the gun, it is necessary to briefly describe the consumable. There are two main varieties on sale:

  • Regular foam. Judging by the name, it is easy to guess that the first option is intended for widespread use. This is an ideal option for those who decide to do the work with their own hands, without the involvement of specialists. The kit comes with a screw tube.
  • Professional… The design of the product is arranged in such a way that the cylinder can be connected to the pistol. The packaging is equipped with a special tip.

There are no other features in the packaging structure.

Professional polyurethane foam has increased wear resistance and strength. Its use is somewhat more difficult compared to the conventional formulation.

In addition to packaging features and technical characteristics, polyurethane foam is divided into segments according to seasons. There are three main groups: summer, winter and demi-season (the product can be used at any time, depending on the weather conditions). This characteristic is very important if the work will be carried out outdoors.

Also on the cylinder, manufacturers indicate the scope of the product. The compositions are used for joining the pipeline, installing entrance doors, insulating structures and other works. Products differ in composition, usability, durability and other aspects.

Device design

Let's take a quick look at how this tool works and what it consists of. It is worth noting that its configuration is very simple. Despite the huge variety of models on the modern market, they are all very similar to each other.

Let's consider the main elements of the device:

  • A tube. This part has two tips, also called nozzles. The tube and nozzles have different diameters, due to which the foam is supplied under high pressure.
  • Trunk. It is indispensable when working with deep holes.Its length can be 20 centimeters. There are two types of element design - collapsible and one-piece. The first option is much more convenient to clean after use.
  • Adapter (he is a reducer). The part connects the container with the consumable to the assembly gun.

In the process of use, it is on this element that the greatest load falls.

  • Adjusting bolt. Judging by the name, it is easy to guess that the required foam flow rate and its volume are selected with the help of the screw. A very useful detail when performing major renovations.
  • Fasteners. This part is responsible for positioning and securing the cartridge inside the gun. Outwardly it resembles an ordinary nut.
  • Adjusting lever. This mechanism is designed to control the speed of the output of the consumable resource, depending on the pressing force.
  • Handle. The central element of the support, which acts as a retainer for the rest of the elements. For its manufacture, metal or heavy-duty plastic is used. In order to improve the convenience of users, special recesses are applied to it under the fingers.

Using the instructions for the device, even a beginner will be able to work with the tool.

The working process

Charging

Each can has a protective cap for airtight storage of consumables. Before using it, you need to remove it and insert the cylinder inside the device holder. Remember the basic rule - during operation, it is imperative to keep the container upside down (that is, the holder should be at the bottom, like the handle, and the adapter should be at the top).

It is not difficult to install the container into the design of the pistol. In the process of screwing in, it is necessary to hold the tool with one hand, and with the other, install the cylinder with gradual rotational movements.

In order for the composition to become homogeneous, the vessel must be shaken. It is desirable to do this in a standard position (handle on top).

It is necessary to carry out about 15-20 shakes.

Foam application

Moisten the area before applying the foam. Moisture is necessary for swelling to make this process faster and more efficient.

The tip is directed towards the seam. Pull the trigger gently and carefully, without sudden movements or jerking. In this case, the possibility of trigger breakage will be minimal, and the quality of the foam at the outlet will be higher. The hole is completely filled with material. As you work, make a side-to-side movement of the nozzle in a zigzag pattern.

Use the adjusting screw to change the amount of foam that is delivered to the barrel. The volume depends on the size and depth of the seam.

So that the composition does not lose its uniformity, do not forget to shake it from time to time.

How to replace a cylinder?

Changing a container with foam is a simple process that does not require special knowledge, exercises, preliminary preparation and other manipulations. Sooner or later, the foam ends and you have to change the empty container for a full cylinder. The replacement procedure is carried out as follows:

  • The barrel of the device must be directed into a bucket or other deep container.
  • To get rid of the remains of consumables, you should pull the trigger and wait until the remaining foam comes out.
  • Next, the device is turned over so that the handle is on top, and the empty container is simply unscrewed.
  • A special liquid compound should be thoroughly cleaned at the attachment point and a new vessel should be installed. The device is now charged and can be used again.

Completion of work

As soon as the repair work has come to an end, the adjusting screw should be tightly closed in order to prevent the access of oxygen to the foam as much as possible. If there is foam in the container, and the next application is planned for the near future, then you do not need to remove the incomplete cylinder. On the contrary, experts recommend leaving it inside the instrument. In this case, the foam will not dry out due to being under constant pressure.

Before the end of using the product, the tip of the nozzle should be treated with a special liquid. This procedure will prevent the consumable resource from drying out. Subsequent use will be much easier and more comfortable, without the need for cleaning before use. If the old cylinder is empty, but there is no new one at hand, it is necessary to remove the bottle, thoroughly clean the construction gun and leave it in storage until the next use.

How do I clean the instrument?

Many people mistakenly believe that cleaning a pistol is unnecessary and, moreover, pointless. However, experts from the field of repair strongly disagree with this statement. Removing foam that has hardened along the entire length of the barrel is a complex, time-consuming and problematic process.

In order not to face this problem, it is necessary to clean the device immediately after completing the repair work.

To begin with, you should turn the barrel in the opposite direction from you. The container with the consumable resource is unscrewed, and instead of it, a cleaning agent is placed in the holder. Push the lever and wait until the tube is filled with the cleaning agent. This procedure needs to be given from 10 to 15 seconds, after which the agent is removed, and a second rinsing is carried out.

When removing the container with the solution, press the trigger to clean the device from its residues. When cleaning is complete, tighten and secure the adjusting screw until it stops.

Keeping the tool clean will preserve its appearance and extend its useful life.
