Any professional finisher canto confirm that the repair of walls in a house or apartment represents a large part of the scope of work. Before their meaning in the external appearance of the home, the ceiling and the floor are clearly receding into the background. Any defects in the surface of walls are strikingly stronger. However, with the help of modern materials and technologies, and also following certain rules, they can be repaired on their own without recourse to hired specialists. This does not require great physical strength and special skills. 
All the defects of the walls are very visible, therefore, the repair of the apartment begins with the restoration of the walls.
Preparatory work: removal of old coatings
Repair of the wall can be started immediatelyAfter it is laid over new communications or repair of old ones is completed. To begin with, it is necessary to remove old coatings that have become unusable. Wallpaper, especially glued more than 10 years ago on the then types of glue, are removed quite easily. If there are areas where they hold tight, they are removed with a wet rag and scraper. It is also better to remove lime deposits with a scraper and only then wash the rests with a wet brush. With a colorful coating, everything is somewhat more complicated. If the flaking areas are easy to remove with a scraper or shoe knife, then places where the old oil paint is held tight, you have to melt the industrial hair dryer before working with the scraper. 
Repair of walls begins with the removal of the oldcoating. Old plaster walls need to be taped with a wooden hammer or simply with knuckles. If there are places where a deaf sound is heard, then it is necessary to delete it, since repair on an unreliable basis is useless. If the exfoliated places fall off quite easily, then, where it holds well, it will have to be knocked down with a perforator or chisel with a hammer if the areas are small enough. They also have to knock down the tile covering from the walls of the bathroom, toilet or kitchen. Save the whole tile is possible only in those places where it was fixed to a simple mortar, and began to lag behind the wall. After all old coatings have been removed, it is desirable to wash the surface from their residues and dust with a brush with water and you can start the next repair stage. Back to contents</a>
Elimination of defects and surface leveling
The walls are leveled with plaster or putty. The repair of walls begins with the presence of cracks on it. If such a crack passes through the entire surface of the wall of the high-rise building and in particular becomes through, it is necessary to invite specialists to repair it. If the crack is relatively small, it can be closed by hand. First of all, it will be necessary to cut the edges of the crack obliquely with the help of a narrow spatula. Then it is properly moistened with water with a foam sponge and a layer of putty is applied, pushing it into the crack with force, so that it penetrates as deeply as possible. Putty should lie not only in the crack, but also on the nearby surface of the wall. If it has protrusions, they are chopped down with a perforator or chisel. After that, the surface is sanded with an abrasive bar. The wall can be leveled either wet or dry. The first is the use of aqueous solutions of plaster and putty, the second involves facing the walls with plasterboard slabs. Plastering will cost significantly less, but it will take more time to install, taking into account the time required for drying. In addition, it should be used only when there is no need for additional insulation in the walls. 
Tools needed for wall alignment. The technology of plaster coating provides for the installation of beacons from the metal profile, which are installed on the sides of the site. They are leveled with a plumb line and pull a nylon line or cord between them. Cement mortar is applied, starting from the level of the floor, and lift the layer upwards. All unevennesses are smoothed with a rule, in the role of which any smooth board of about 1.5 m long can be used. As a finishing coat, it is possible to apply a plaster coat on the cement plaster with a spatula. After that, you can paste wallpaper or apply a different decorative coating. Drywall has a sense to mount in two cases: if a wall before this is installed a layer of insulation, if the repair time is very limited. In the first case, a frame of a metal profile is fixed on the wall, in the intervals between the posts there is a thermal insulation material. It is already attached to it gipsokartonnoe coating. In the second case, you can do without the frame, you just need to lay the waterproofing and then fasten the plasterboard with plastic screws on the plastic plugs. Back to contents</a>
Repair of the external surface of walls
Scheme repair of the outer surface of the wall. As well as inside the house, from the outer surface you need to remove the crumbling plaster and repair the cracks. The simplest way to repair walls from the outside is to apply plaster. It practically does not differ from carrying out such works from the inside, only in cement mortar it is desirable to add a liquid glass to prevent penetration of dampness. If the wall needs to be insulated, then a frame from the profile is mounted on it, and a heater is installed in its intervals. Only as a cladding is used not plasterboard, but plastic siding. It is also possible to install ready-made facade cassettes, to wall the wall with a natural or artificial stone. In general, it can be stated that for repairing the surface of the walls both inside the house and outside, some knowledge and skills are needed in carrying out the finishing works. And if small cosmetic repairs can be produced on their own, then for more capital works it is desirable to attract specialists so that the result would have a decent quality. Then the walls will delight the eyes of the owners and guests of the house, and not create problems for the tenants.
