If you turn to a professional finisher, he will surely tell you how to close a hole in the wall. But if you ask no one, you will have to act on your own. Having settled in the apartment, you will spend a lot of effort to equip the space. On the walls will need to be fixed shelves and cabinets, household items and more. If you have a plasma, then you can fix it using a reliable bracket. For each fastener, you will need to drill a hole, which can subsequently become a hole that requires sealing.
Preparation of tools and materials
How to seal a hole in the wall - this question is one of the most common during repair. Holes usually remain after routine repairs. If you plan to move the lamp to another place, then you will need to remove the bracket on the wall. Such a defect can be covered with putty and level out. As soon as the composition hardens, the stain is cleaned with sandpaper and sealed with wallpaper. Some paint the surface with paint.
If at the junction of the walls a fragment of concrete has moved away, then the hole cannot be removed in the manner described above. It will be necessary to use other materials and techniques. For work you should prepare:
- putty knife;
- a vacuum cleaner;
- tassels;
- sand paper;
- polyurethane foam;
- piece of foam rubber.
Note
This list is supplemented with putty and finishing materials. If we are talking about a through hole or a chipped large volume, then you can use the solution. In order to facilitate the work and speed up the process, it is necessary to purchase a ready-made solution, which is sold in dry or liquid form, because it will be convenient to work with it.
Work with concrete wall
If you are interested in how to close a hole in a concrete wall, then first you need to evaluate the amount of work. If the defect is small, then it can be eliminated without preparation. But if a hole with a large area, then you have to act differently. Do not rush to do the work in haste, because your efforts may be in vain - a piece of plaster over time will depart from the surface.
To seal a large hole, you will need to provide reliable adhesion between the mortar and the wall. The hole is cleaned of dust settled inside. A vacuum cleaner will help. After that, the surface is moistened to ensure reliable adhesion to the liquid solution. If this recommendation is neglected, the wall will draw moisture from the mixture, as a result of which it will not be possible to form a monolithic compound.
If the hole is larger than 5 cm in diameter, it should be filled with a piece of brick or concrete. The remaining space is covered with a solution. As soon as it hardens, the surface must be covered with putty. After each operation, you must wait for the solution to set well. At the final stage, it is necessary to clean the repaired area with sandpaper. Then you can do wallpapering or painting the wall.
If you are still worried about how to repair a hole in a concrete wall, you should consider what material to use. If the repair is carried out in an old building, where old plaster is crumbling, and a finishing solution is pouring from the corners, then you can use polyurethane foam to seal the hole. The volume formed in the corner between the walls is filled with 3/4 foam.
After that, a special mixture is bred for sealing deep chips in concrete walls. The remaining volume is filled with this mixture in several approaches, and then left until solidification. Finishing should be done with putty. At this point you can achieve a flat surface.
Small hole in the concrete wall
If you want to know how to fix a hole in the wall, then you need to evaluate the amount of work. When the hole is small, it is closed with foam. If we are talking about a defect with sizes smaller than a matchbox, then you can use putty. The surface is cleaned of dust before being manipulated and wetted with water.
Putty in the next step must be applied in several stages. If the hole has a small area, but deep enough, it should also be cleaned and moistened the inner walls. Next, begin to rub the putty and smooth it on top. Once the mixture has hardened, places can be cleaned with sandpaper. At this stage, we can assume that the process is completed. Wallpaper is glued onto the repaired place or paint is applied.

First you need to take a dowel with a diameter equal to the size of the hole.
The algorithm of work
In order for the putty or mortar used to penetrate better, the hole must first be expanded. You can do this all the same dowel, moving them back and forth. It is further recommended to remove dust from the inside. It should not be blown out, as dirt can get into the eyes. It is best to use a vacuum cleaner.

Removing the space between the bathroom and the wall
Even if there is a small gap between the wall and the bathroom, it can cause major trouble. For example, water falling there may seep to the neighbors. You can avoid such consequences at the repair stage. Cement mortar, which is a universal remedy, is excellent for these purposes. But this decision cannot be called the most aesthetic. After completing all the work, you will have to give the embedded gap an aesthetic appearance.

It is important to achieve a consistency of thick sour cream. Before closing a hole between a bathtub and a wall, you should evaluate the size of the gap. If it is wide enough, then the solution will spill onto the floor. In this case, soak the mixture with an old rag and fill it with a gap. When the rags dry out a little, moisten the gap and start pouring the solution there.
The outer part of the seam should be as narrow as possible. Considering the material that underlies the decoration of the bathroom, you can choose a way to mask the seam. If the walls are finished with tiles, then a border from its remains can be laid out on the side. If you used plastic panels, then they are laid on top of the seam. You can use a plastic border. But when the walls are painted, the seam is covered with the same paint, however, the surface must first be puttied.

Plastering a hole in a plasterboard wall
There are many methods for carrying out these works. You can choose the one you like best. For example, you can put a patch on a treated hole by planting it on a cast. From above, all this is fixed with duct tape.
The base is covered with putty and painted to match the color of the wall. If the hole is large enough, then the salary can be fixed with a screw, then plaster and putty are again applied. The final step will be staining.
