Cracks in the walls are one of the most important problems in apartment buildings and private houses. Because of such cracks, paint very often begins to crack and crumble, wallpaper peels off, and other troubles occur that I would like to get rid of. But cracks occur not only because of the builders - it can also happen because of many natural phenomena, such as earthquakes, earth settling and others. You just need to understand that nothing eternal exists, and the problem should be solved as it comes. But cracks can be very different - be it the initial stage or rather serious damage. But one conclusion should be made - it is necessary to close the crack in the wall as early as possible, so that later you do not have to invest more effort and money to eliminate this problem. Better to cover up and patch up "in the first couple",than to make repairs in the apartment later.

How and how to fix a crack in the wall

You may encounter completely different cracks in size and origin. Perhaps your plaster or putty just cracked, but if the cracks were caused by the brickwork itself, then this is already a more serious problem. But still, you can cope with the first and second options, you just need to know how to do everything correctly, that's all. Let's try to learn some methods that will help you get rid of cracks in the wall or a hole in the wall that have already appeared.

If there are small cracks on your wall that look like a cobweb, then in order to cover it up, you may need a primer (see which primer to choose) and a putty mesh. But remember, this option may work only if the cracks do not diverge and the wall has only minor damage. So, let's get down to business. First of all, it is necessary to clean off all old building materials and all kinds of debris on the surface from the wall. It is important that the wall is perfectly clean. Now that you have done this work, you need to prime the wall with deep penetration soil. Then glue the reinforced filler mesh over the entire wall area. Remember that the entire area of the cracked wall should be covered with mesh. After you have applied the mesh, you need to coat the surface with a small layer of putty on top. After complete drying, you need to sand the wall,after which you can start painting or wallpapering. Thus, it is easy and quick to repair a crack in the wall.

If you are faced with such a problem, when small cracks have gone from the outside of the wall, then you should do the same work as in the previous version of getting rid of cracks, but there is still one caveat - choose Ceresit CT29 for the putty. This putty is designed specifically for outdoor use and does not need sanding, as it is reinforced by itself. Moreover, this putty is very resistant to weathering, as it contains special adhesive additives.

If significant cracks have gone on your wall, not only on the plaster, but also on the brickwork, then here it is worth resorting to another option of how to repair the crack in the wall, since this problem is already more serious than in the previous versions. First of all, you need to completely remove all old plaster from the wall. After you have cleaned the wall, you need to fasten a special metal mesh for plastering to it, and after that apply a new layer of cement-sand plaster. But it is very important to remember that the mesh must be screwed over the entire surface area, thereby preventing new plaster from spreading, after which it will be possible to putty, paint, and so on.

But it is worth starting to take drastic measures in the event that the crack in the wall has already begun to diverge a littleā€¦ In this case, you will have to pull the wall together so that it does not diverge further. It is necessary to tighten the crack with special metal plates. But before that, knock all the old plaster off the wall. It is not possible to knock down the plaster from the entire surface area, but only half a meter on both sides of the crack, since the metal plate is usually attached one meter. After you knocked down the plaster, you need to clean the crack from solutions and other debris, then fill it with polyurethane foam. Now you can attach the plate. But there is an important point - when choosing a plate, you should definitely pay attention to the fact that it cannot bend easily, especially since it should not bend by hand - this is important. It is worth choosing a plate that is made of thick and high-quality metal.

The crack in the wall should be pulled together in three places, and this is only a minimum. If possible, then you can make four or five ties. But if you chose the first option, then the mandatory places of the screed are:

1. Top, while stepping back a little space from the ceiling.

2. Bottom, slightly stepping back from the floor.

3. In the middle.

You can screw the plates onto the most common self-tapping screws, after driving in the dowels, or you can push them onto the bolts with a nut, punching through the plate. After you have made the screed, you can wind up a special metal mesh and see how to do the plastering of the walls with your own hands with a video example, and if you are familiar with this, then get down to business accordingly, because now you will not say that you do not know how to repair the crack in the wall. Good luck!
