Perhaps every person dreams of a cozy apartment and a beautiful renovation. However, if all this splendor fades in rooms with uneven walls, then you can eliminate the errors yourself by pasting wallpaper at the final stage.
Surface preparation
If you are thinking about how to process the walls before wallpapering, then you first need to free them from old coatings. It is important to exclude the presence of crumbling areas, as well as dilapidated plaster. At the next stage, the wall is primed with a roller, sprayer or brush, and then the base must be left for 12 hours until completely dry. Therefore, it is best to carry out these manipulations in the late afternoon, so as not to waste time in vain.
Selecting the alignment method
If you are faced with the question of how to process the walls before wallpapering, then it is important to choose a way to level the surface. Today, two methods are most commonly used, the first is wet and involves the use of building mixtures,while the second involves the installation of sheet structures. These technologies are good, but only if you can follow all the rules. With small differences ranging from 30 to 50 mm, it is best to treat the walls with plaster. Of course, this method is also applicable for processing walls with a large curvature, however, such work will be accompanied by additional financial costs for materials and work. Therefore, in the case of large differences, it is best to install the frame and sheathe it with drywall.
Processing walls using the beacon alignment method
If you are thinking about how to process the walls before wallpapering, then you can use plaster, its use involves the installation of beacons. Do not forget about electricity, which must be turned off before starting manipulations. In the process of cleaning the walls, you must act as carefully as possible, because you must not damage the electrical wiring elements that run in the wall.
For the most durable fixation of the plaster, the walls should be primed before wallpapering. What exactly is better to use, you can find out from consumer reviews, which say that Ceresit is one of the most common formulations. This material eliminates unwanted delamination of elements and increases moisture resistance. If you have to work with cement mixtures, then you should use cement milk, which is prepared from sand, water and cement.
If you still have not decided how to process the walls before wallpapering, then you can resort to the wet method on the lighthouses. These elements are metal products that are made of flexible aluminum. Beacons are installed on a curved wall, and subsequently they will be aligned. If the wall is littered up, then the lighthouse should rest against the wall from below, while on top between the lighthouse and the wall there will be a material of the “Rotband” type, it will be possible to remove irregularities with it.

The leveling compound may have gypsum or cement as binders. The latter option is more suitable for bathrooms and kitchens, as well as for those rooms in which conditions are characterized by high humidity. If you want to process the walls before wallpapering in living rooms, then it is best to use a gypsum mixture that will be able to maintain the microclimate inside the premises.
Wall treatment with plaster

The mixture should not be too thin, as in this case it will slide off the surface, but if it is very thick, then it will be problematic to distribute it.
When using gypsum compositions, their quantity should be such that you have time to work outmixture for an hour. Once the wall is finished, a rule should be used to level the surface by moving the tool from bottom to top. If it happens that in some zones there is not enough mixture, it must be added and again carried out by the rule. These manipulations must be repeated until the wall is perfectly even.
After the plaster layer has dried, you can process the roughness of the wall using a finishing putty. Among other things, you have to sand the walls with fine sandpaper. This method has many advantages, since it does not take up useful space, but the disadvantage is the need to pre-clean the walls, which is a laborious process with the formation of a large amount of dust and debris.
Materials in the wall treatment complex
Wall processing before wallpapering is carried out with several materials. At the first stage, a spray is applied, the layer thickness of which should be from 3 to 9 mm. This layer will consist of plaster, but the second one will consist of a primer. Its thickness usually does not exceed 6 mm, but the priming layer can be applied in several layers. At the third stage, plaster is applied, the layer of which can vary from 2 to 4 mm. The essence of this process is to create a film, which is subsequently overwritten.
