How and how to eliminate a crack in the wall
You can encounter completely different cracks in size and origin. Perhaps, you just cracked plaster or putty, but if the cracks itself gave the brickwork, then this is a serious problem. But still with the first and second option you can cope, you just need to know how to do everything right, that's all. Let's try to learn some methods that will help you get rid of already appeared cracks in the wall or holes in the wall.
The putty mesh will help to remove a crack in the wall.
If there are small cracks on your wall that resemble a spider's , then in order to cover it, you will need a primer( see which primer to choose) and a putty mesh. But remember, this option can only be approached if the cracks do not diverge and the wall has only minor damages. So, let's get down to business. First of all, it is necessary to clean off all old construction materials and all sorts of rubbish on the surface from the wall. It is important that the wall is perfectly clean. Now that you have done this work, it is necessary to prime the wall with a deep penetration primer. After that, glue the reinforced filler mesh throughout the entire wall area. Remember that the grid should cover the whole place of the cracked wall. After you have applied the mesh, it is necessary to cover 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, to seal a crack in the wall simply and quickly.
If you encounter such a problem, when small cracks have gone from the outside of the wall of the , then you should do the same job as in the previous version of getting rid of cracks, but here still there is one nuance - for plastering choosemeans Ceresit CT29.Such a putty is designed specifically for outdoor work and does not need sanding, as it itself is reinforced. Moreover, this putty is very resistant to weathering, since it has special glue additives in its composition.

If on your wall there are significant cracks not only on the plaster, but also on the brickwork , then here it is necessary to resort to another option how to seal a crack in the wall, since this problem is more serious than in the previous versions. First of all, you need to completely remove all old plaster from the wall. After you have cleared the wall, it is necessary to screw a special metal mesh for the plaster to it, and after that apply a new layer of cement-sand plaster. But it is very important to remember that the grid must be screwed over the entire surface area, thereby it will not allow the new plaster to spread, after which it will be possible to putty, paint and so on.
But it's worth starting to take drastic measures in the event that a crack in the wall of the beginning is already slightly divergent .In this case, you have to pull the wall together so that it does not go further. To pull the crack you need special metal plates. But before that, knock off all the old plaster from the wall. You can not bring down the plaster from the entire surface area, but only half a meter on either side of the crack, since the metal plate is usually fixed to one meter. After you knocked off the plaster, you need to clean the crack from solutions and other debris, then pour it with mounting foam. Now you can mount the plate. But there is an important point - when choosing a plate, you should pay attention to the fact that it can not easily bend, the more it should not bend by hand - this is important. It is worth choosing a plate that is made of thick and high-quality metal.
A crack in the wall should be pulled together in three places, and this is only a minimum. If possible, you can make four or five ties. But if you chose the first option, then the binding places are:
1. From above, while retreating a little space from the ceiling.
2. Bottom, slightly receding from the floor.
3. In the middle.
Plates you can fasten to the most ordinary screws, pre-driving the dowels, and you can attach them to the bolts with the nut, punching through the plate through. After you have made the screed, you can wind a special metal mesh and see how the plaster of the walls is made with your own hands with a video example, and if you are familiar with this, then proceed accordingly, because now you will not say that you do not know how to seal a crackin the wall. Good luck!
