Renovating your home is a bit of a hassle, but it is a fun activity that allows you to change the environment and make it more modern and attractive.
Sometimes after repairs you can see thispicture, that small and sometimes even large cracks appear on the walls. Many owners begin repair work with finishing the walls. And here the first disappointments await: some time passes, and the surface is covered with small cracks. The reasons for their occurrence may differ, but the methods of elimination are the same.
Why there are cracks on the plaster
A crack in the wall is a common occurrence,inherent in premises in new buildings, but quite common in other cases. Most often, the cause of defects is the shrinkage of buildings after construction. If we are talking about real estate that has been used for many years, the appearance of cracks can be caused by the following factors:
Reasons for the formation of cracks in walls.
- impact of temperature changes or drafts;
- vibration of the house from a nearby passing vehicle;
- illiterate prepared shpatlevochny composition or violation of the technology of its application.
If we are talking about the occurrence of a crack afterrepair work, the most likely cause is the use of low-quality plaster. In this case, cracking can be caused by a solution that contains a large amount of binders (fatty) components or is poorly mixed during preparation. Binding components accumulate in one place and lead to the appearance of a defect. In addition, the wall surface can crack when a large amount of putty was applied in one go. The combination of a thick layer and a long drying time inevitably leads to cracking. The longer the composition dries, the smaller the layer that must be applied. Defects can also occur when the subsequent layer of material was applied to the undried first layer. Of course, cracks spoil the appearance of the room and can reduce all efforts to carry out repair work to zero, but do not despair: such defects can be successfully eliminated on your own.

Preparation for work and algorithm for carrying out repair activities
If cracks appear on the plaster,look like a fine mesh, you can get rid of them using regular water-based paint. If the thickness of the defect is greater than a human hair, you need to use putty.
Algorithm for identifying and eliminating cracks in walls. Here, to carry out repairs, you will need to prepare the following materials and tools:
- a container with water;
- a wide brush or spray;
- narrow and wide spatulas;
- putty.
First of all, it is necessary to designate the areawork. It is necessary to carefully examine the surface for minor or major defects. After this, the cracks must be cut with a narrow spatula, which will allow the putty to stick more firmly to the plaster on the walls. One of the reasons for the appearance of defects on a recently treated surface is a violation of the rules for applying putty. Most often, it manifests itself in the rapid absorption of moisture by the walls, which is contained in the putty solution. To prevent the putty from cracking, it is necessary to wet the walls with water using a brush or sprayer before starting work. If the damaged area is quite large, it should be divided into sections of about 1 m3 and processed one after another. Then you need to take a wide spatula, scoop up a little of the composition, placing it along the edge of the tool, and draw the blade of the spatula across the crack. Thus, the putty will penetrate deep, better filling the voids. The action must be repeated, performing it until the entire area is processed. After this, the repair technique changes slightly: now you need to process the cracks with a spatula not across, but along, moving from top to bottom. In this case, the tool must be held at a slight angle to the wall. When all the defects are repaired, you should remove excess mortar and level the surface of the walls for final sanding.

Removing debris and large defects
Often, in places where cracks connect, pits and other large defects can form. They must be treated as follows:
Before sealing the crack, it should be thoroughly cleaned of dust and dirt using a brush.
- The edges of the notches are cut using a narrow spatula;
- brush removes dust and particles of putty;
- water is applied to the plaster;
- The notch is sealed with a putty compound across, left to grasp and processed repeatedly by moving along.
In this case, it is necessary to ensure that the solutionfirmly adhered to the plaster and did not fall out during subsequent finishing. To seal cracks and large defects, experts recommend using a special foamed putty with expanding properties. In appearance, this composition resembles mousse, it is easy to apply and dries quickly. To apply foamed putty to the surface of the walls, you will need to prepare a rubber spatula or another tool with a flexible elastic blade. Return to contents</a>
General recommendations for putty work
In order to prevent the wall surface from cracking, it is necessary to follow certain rules and recommendations. Thus, the following actions will help to avoid cracks:
