Advantages and disadvantages of working with
material Today both professional builders and home masters do not imagine the installation of doors and windows, as well as many other works without this useful material. Working with the mounting foam is really very convenient, because it does not require the presence of additional mechanical devices or sources of electricity.
The merits of this sealant include its high sealing, installation, heat and sound insulation characteristics. It penetrates into all hard-to-reach cracks and joints and fills them, suitable for work with almost any building material, be it concrete, brick, glass, wood, and so on. The use of mounting foam repeatedly accelerates the process of sealing and installation, work with it is very labor-intensive.
Among the shortcomings is worth noting the reaction of sealant to ultraviolet. Polyurethane foam does not tolerate sunlight. Before working with the mounting foam, you need to wear gloves and goggles, and in closed, poorly ventilated rooms you need to use a respirator, because the vapor of the drying foam irritates the mucous membranes and skin.
Assembly during repair - we use foam
Foam mounting, the instruction for which is always written on the back of the cylinder, is quite versatile in terms of the terms of use. If you follow simple rules when working with it, the result will please you. All work is best done in a warm season at a temperature of +5 to +30 ° C.
The higher the temperature and humidity of the air, the faster and better the polymerization process, that is, solidification. Of course, the limits of the reasonable is, at a temperature above +30 degrees, foam will behave unpredictably, most likely, the seam will become unusable.
Before using the mounting foam, it is necessary to shake the bottle well for a minute so that the chemical components inside the container mix and its contents become uniform. After this, it is necessary to unscrew the cap, screw the tube onto the adapter and turn the cylinder upside down.
Ideal if you have a special gun for applying mounting foam. It will not only reduce its consumption, but will also greatly simplify the work. This option works only when using its sealing and mounting properties, for example, when installing windows and doors, sealing gaps and joints, but this does not end the use of sealant.
Foam gun - convenience for insulation
One-component polyurethane foam assembly is also used for thermal insulation of buildings and construction sites. Spraying the mounting foam on the surface to be insulated is carried out using a special pneumatic gun.
Its device and principle of operation are akin to a spray gun. The balloon is screwed to it as well as to a regular gun, using a threaded adapter. When the clamp is pressed, the composition under the action of one of its components passes into the nebulizer, opening the complex valve mechanism. The pressure of the foaming liquid is regulated by a gun. A special regulator on the injector sets the shape of the exhaust torch.
With the acquisition of skill and skill, you will understand how to apply the mounting foam, because when working with it, it is not necessary to be a highly qualified specialist. If nevertheless it remained unclear how to use the mounting foam, the video will explain the incomprehensible technical subtleties.
