Modern developers are increasingly using bricks in their work, but almost all typical high-rise buildings are built using panel technology. The owners of such apartments do not need to talk about the fact that the quality of the buildings leaves much to be desired. They can be cold and humid in winter, and also quite noisy.
In order to isolate the apartment as much as possible from external sounds and cold air, it is recommended to repair interpanel seams from the inside of the premises. In this case, you can take the help of professionals and save time or do the work yourself. You do not need to have specific skills or experience to do this. The most important thing is to strictly follow the technology.

Sealing interpanel seams in the apartment
In the process of work, you need to use ordinary building foam. Seams should be carefully filled with material and not to save. Excesses are cut with a clerical knife after the foam has completely dried. Full solidification usually takes 24 hours. Time depends on the temperature and humidity level of the room.

Experts note that for better adhesion of materials, joints in the walls should be thoroughly cleaned and degreased. To protect the surface of the wall from the subsequent occurrence of fungi or mold, the surface of the wall, including the mounting foam, filling the joint, with a primer and putty should be treated.
In addition to polyurethane foam, you can use other modern materials with insulation and waterproofing properties. When choosing it is important to pay attention to their composition, which should not contain chemical or toxic components.
The use of polyurethane foam
This insulation can be used in conjunction with a mounting foam. At the initial stage of the work, it is worth cleaning and degreasing the joints, allowing them to dry and fill with construction foam. It is necessary to fill them in half. In the process of drying, construction foam will increase in size.

After it hardens along the perimeter of the seam, it is necessary to lay additional insulation in the form of a tape of polyurethane foam. After mounting the tape, it must be primed and puttied, and then proceed to the decorative facing of the wall surface.
The combination of materials gives a positive and durable result, prevents the shrinkage of the building structure and the penetration of cold air into the room.
