When starting to carry out repairs to the premises related towallpapering, a thorough inspection and alignment of the walls is carried out, since their surfaces have various defects. Alignment of walls for wallpaper is necessary if there is damage, which can take the form of cracks, holes, bumps.
To ensure that the wallpaper lies flat and without flaws,it is necessary to level the walls in advance. At the same time, the walls may not have a common plane. To create an ideal surface, a solution of cement and sand was usually used. There are a number of methods for leveling walls, each of which depends on the degree of deviation of the wall plane from acceptable standards and the presence of damage. When performing work, the material from which the walls of the room are made is taken into account. The compositions used for leveling can have different purposes and properties characteristic of them. It is impossible to give an unambiguous answer to the question of what material can be used to qualitatively level the walls for wallpapering.
Aligning the walls with wallpaper putty

Tools for leveling walls.When old wallpaper is removed, you may find that the surface of the walls is covered with cracks or holes no more than 30 mm high. To create an ideal surface, you should use materials with tools such as:
Apply the putty with a wide spatula (up to 400 mm),and narrow ones should choose the composition. Putty that can harden in one day with a sufficiently large applied layer (3-5 mm) is more effective. Do not use putty above the norm, as bumps and lumps may appear, which will need to be beaten off with a hammer after applying the solution to the walls.

Scheme of installation of beacons for leveling walls.To obtain a flat plane, you should prepare beacons for each of the four corners of the room. The marking is done by randomly applying small parts of thick gypsum putty in the corners. This will allow you to set point beacons. Using a building rule and a level, beacon strips are created vertically using putty with the help of a solution. They should be perfectly aligned in accordance with the level. Then the composition should dry in 3-12 hours, which will depend on the layer of putty applied to the walls. Therefore, the putty is applied taking into account the optimal thickness. When the point beacons have already dried, using a rule and a wide spatula, putty mass is applied along each axis from the beacons. When applying the rule, the mass should be rubbed until a closed contour is obtained. Before leveling the walls, prepare a rule, the length of which is much shorter than the width of the walls, a twine or cord is pulled in three places. After pulling the cord from the putty, an additional vertical should be applied. The beacon lines should form a space that is filled with putty and leveled with a spatula. Return to contents</a>
How to level the walls with your own hands qualitatively: recommendations
The process of plastering walls.For thorough surface treatment before wallpapering, when starting to level the walls, take into account all the nuances associated with the correct conduct of the preparatory stage and the execution of work. In order for the wallpaper to lie flat and last longer, the entire technological process, which has an aesthetic value, should be strictly followed. In general, the leveling process depends on the original condition of the walls. If you need to repair the premises of a house that has recently been built, then before leveling the walls for wallpaper, they should be covered with plaster. Then they must be putty. Plaster can be applied to a brick surface, aerated or foam concrete. The composition should be prepared, observing the ratio of the components of the mixture, consisting of 4 parts of sand (fine-grained) and 1 part of cement. As a result, you can get a material that is coarse-grained. It is applied with a spatula up to 2 cm thick. The use of cement-sand mortar will help to level the walls that have the greatest flaws. The wall will dry completely only after 2-3 weeks. A primer composition should be applied to it to ensure high-quality adhesion between the layers. Gypsum-based putty is best suited. It has the property of excellent air permeability, and its composition includes only environmentally friendly components. Starting and finishing putty are used, which is determined by the size of the particles in its composition. To apply the first layer (2-3 mm), the starting putty is diluted with water to obtain a liquid with the consistency of thick sour cream. All proportions are indicated by the manufacturer on the packaging. Since the mixture can dry very quickly, it is used immediately after preparation, but not more than 1 kg. It should be applied with spatulas. One spatula is applied to the wall at an angle, then the mixture is smeared.
The final stage in leveling the walls isgrinding. Next, start from the floor and move towards the ceiling. To ensure uniform application, alternate all hand movements with a spatula. They should be horizontal and vertical. After applying the starting layer, clean the wall surface the following day. Special nets are used for this. A respirator should be used during this procedure. Next, prime the surface again to apply a layer of putty, which is the finishing one. Apply a layer 1-2 mm thick. When applying, repeat the step of leveling with the starting putty. The entire surface should turn white. Since the material is fine-grained, it will hide all irregularities. It should dry within a few hours. Next, grind and prime the surface. If the primer is instantly absorbed into the wall, apply it again. After this, begin to wallpaper the walls. In some cases, the surface can only be leveled by using the finishing putty. After applying it in one layer, begin to wallpaper the walls. To save time and money, you can level the walls using sheets of plasterboard. It is glued with glue or screwed with screws. When the sheets are mounted, they are covered by applying a finishing putty. Return to contents</a>
How to level the walls under the wallpaper and properly primed surface
Surface priming is required on each ofstages of work. The primer is applied using a roller with a telescopic handle. If any minor irregularities are found on the walls, they can be hidden by pasting thick wallpaper. Preparation of the walls for covering with wallpaper is completed by applying a primer. It has the highest degree of adhesion. The primer can be mixtures that have various additives, for example, waterproofing or fungicidal. You can also prime the surface with ordinary wallpaper glue, which should be diluted with water in large proportions. The glue should be selected depending on the type of wallpaper that will be used. They can be paper, vinyl or non-woven. When buying glue, you should carefully read the instructions for it. It is very important to monitor the temperature and humidity levels in the room during the process of preparing the walls for wallpapering.
