How to fix cracks in a wall
All buildings are destroyed over time, and this process is irreversible. However, it is possible to extend the life of the property, for this it is necessary to carry out repairs in a timely manner and close the resulting cracks. When renovating their homes, many are forced to face this problem. in the wall so that the further repair process turns out to be of high quality?
Why are many structures subject to destructive processes?
In order to eliminate a crack in the wall, you need to find out the cause of its formation and establish the material from which it is made. To do this, an analysis is carried out, finding out the size and location of the crack.
It should be noted that gaps occur in a variety of cases: errors or complete non-compliance with the technological process of laying building materials, assembling drywall, laying concrete or incorrectly made proportion of the plaster mix, incompatibility of building materials of walls and plaster, sudden changes from heat to cold. There are a lot of factors influencing the appearance of cracks and cracks.
We get rid of cracks on the plastered wall
Both for external and for walls inside the structure, the destruction of plaster is one of the most common problems. They very often form on sand-cement plaster. Most often - they are quite thin, not thicker than a hair, and they are usually located along the entire wall in the form of a cobweb. They are especially noticeable after priming plastered walls. This happens when the proportion is violated during the preparation of the plaster mixture, as well as when it is incorrectly applied or after care for the surface. It also happens if the material is applied in a thick layer at a time (more than 2-3 cm), this is unacceptable, as the technology is violated.
Among other things, cracks may appear when it is done (painting or wallpapering). To avoid this, before the final putty, it is necessary to reinforce the wall. Various building materials will help with this, for example, painting fiberglass, fiberglass mesh or. Considering that glass wall papers are much more expensive, we will not focus on them, it is only worth noting that the method of their application does not differ from gluing fiberglass.

Fiberglass is considered the best option for eliminating cracks in the walls. It is fixed on a special glue (for glass fiber) (treated with soil) base, followed by puttying or painting without applying it. Due to its structure, fiberglass is a reinforcing material.
When the walls are deeply damaged, the options for elimination
One of the main reasons why cracks appear in the walls is the uneven settlement of the constructed structure. First of all, this applies to new houses, which during the first two or three years after construction give a draft. After this period, most often, the built house no longer precipitates so much and rarely cracks. However, this is not insurance against further slight deformation and, therefore, cracks will appear anyway.
In addition, the cause of cracks and crevices on the walls may be non-compliance with the technological process during the construction of the building. This includes an incorrectly made cement composition, and improper laying of stone blocks or, as well as a violation during the construction of the foundation, etc.
Under various circumstances, cracks appear in the walls and. If the cracks are deep, then beacons should be set first to determine if they continue to expand. Lighthouses are a control seal of cracks in some places with a cement mortar for research. If there has been an expansion of cracks, first establish the cause of their creation and only at the end of the process close them. If there is an increase every day of the crack, you need to turn to professionals to prevent the destruction of the house and ensure the safety of your life.
If GKL cracked
The plasterboard wall is cracking, mainly at the seam. A problem arises when non-compliance and fixing of GKL sheets. For the correct installation of sheets, you need to study the rules for installing GKL. A common mistake is also the one that the seams in drywall are not properly sealed. However, sometimes there are other cases, for example, a sharp temperature drop in the room, great dampness or a flood. When interacting with water, drywall is subject to deformation, and when it dries, it cannot be corrected. This leads to its complete replacement in case of flooding.
- capacity to prepare the plaster mixture;
- grater and half grater;
- steel trowel;
- Master OK;
- brush and brush;
- small trowel for filling small holes.
You can make a solution yourself, or ready-made dry plaster mixes are sold in stores, which are diluted with water.
According to the advice of experts, for better sealing of cracks in the wall surface, it is recommended to use reinforced tape, thanks to which cracks do not spread further.
Summing up, it can be noted that, if cracks are identified, first you need to decide on the correct selection of the option for sealing cracks. And then the surface will be repaired quickly and efficiently, and for a long time you will not have to resort.
