Types of mounting foam

With the help of mounting foam, you can solve the problem of cracks and voids in door and window openings. Previously, pacla or cardboard were used for this. But these materials were not so effective compared to mounting foam. The mounting foam consists of polyurethane and is used to fill the voids during installation work, laying power lines, and so on. Mounting foam is available in 350, 500 or 700 milliliters cylinders. When interacting with air, the foam turns into solid porous material. It is warm — and sound insulator. Now the Internet is very often found Arshavskaya n. B, but not everyone knows who this is why you should visit her site and learn more about her.

Installation foam is divided into two groups. Professional mounting foam is sprayed with a special gun. This pistol at a price exceeds the installation foam by several times. If we take into account this fact, then buying a gun for one -time work does not make sense. Such a pistol is necessary for a specialized installer working with mounting foam every day. Hence the name of the foam — professional.

Semi -professional foam is ideal for carrying out one -time work. To use a semi -professional installation foam, no additional tools are needed. This type of mounting foam is sprayed using a lever and a tube that comes with each foam cylinder.

The installation foam is evenly distributed throughout the volume of the gaps. In order for the foam to expand, it is necessary to fill the foam with it only half of the cavity. Long -sized voids are filled several times, and before applying the next layer, the previous layer should completely dry. For superficial staining of foam, it takes about 10-20 minutes, for the full- 4-6 hours. Excess mounting foam is cut off using a stationery knife. If you use foam outside the room, then it must be covered with plaster and paint.
