Aligning the walls of the room

Almost always, renovation in a new apartment begins with an event such as leveling the walls. Unfortunately, the geometry of their surface in most cases is far from ideal and in order to bring the apartment into the appropriate form, it is necessary first of all to resolve this issue..

There is nothing complicated in the technology of leveling the wall. To do this, you must have a minimum of experience in construction and renovation, and the appropriate tools and materials. There are several methods for eliminating this problem, the first is plastering and the second is sheathing the wall surface with plasterboard sheets. Each of the methods has both advantages and disadvantages, so it is worth considering them in more detail..

Plastering walls

The main disadvantages of plaster are the laboriousness of the process, the mandatory presence of skills in this area, a significant amount of dust and dirt that will arise during the performance of work. Advantages – a wall with a perfectly smooth surface, which will require repair after a sufficiently long time.

What you need to work? The first task is to clean the walls from the layer of old plaster, if any. Then the surface is washed from dust and dirt adhering to it and covered with a primer. This process is of great importance because the better the preparatory work is performed, the easier the subsequent process will be..

Tools and materials:

  • Construction mixer
  • Tanks for mixing plaster mix
  • Lighthouses
  • Rule from 1.5 to 2m
  • Plumb line
  • Building level
  • Plaster mix in the required amount

Calculating the right amount of the mixture is quite simple. Based on average data, in order to apply a layer 2 cm thick on 1 square meter of surface, you will need about 16 kg of mortar. But it is worth buying material with a margin, especially if there are significant flaws. In this case, the thickness of the plaster can reach 4-5 cm..

Use of beacons

First of all, the threads are stretched horizontally along the wall, approximately at a distance of 0.5 to 3 cm from the surface, it depends on the existing curvatures. Fastening of threads is made on nails hammered in the corners.

Then you can place beacons. They are easy to install. To do this, the beacon must be slipped under the threads and fixed vertically with putty or dowels.

Lighthouses are installed at a distance of at least a meter and a half from each other. The less often these elements are installed, the easier it will be to apply the putty. But if they are too rarely located, then the process can be quite difficult, because the application of the mixture between the beacons is one technological operation and is performed in one go.

Putty work

The pre-prepared mixture is applied to the surface using a special scoop, and then it is leveled with a rule. Plastering is carried out in stages, between the installed beacons.

After applying a layer of plaster, let it dry. It usually takes 2 to 4 days depending on the room temperature.

When drying, it is undesirable to open windows in order to avoid drafts. It is also not recommended to carry out work in the winter in a room that is not heated. Recommended temperature for plastering walls – +10 degrees Celsius and above.

Leveling the base wall surface with plasterboard sheets

Working with drywall is less difficult than plastering. The main advantages of this approach are low labor intensity of the process, minimum of dirt and dust, low weight of materials. Disadvantage – due to the need to install the frame and a certain thickness of gypsum plasterboards, the total area of ​​the room decreases. So this method is not recommended for use in small rooms..

Materials and tools

  • Building rule
  • Screwdriver
  • Plasterboard sheets
  • Self-tapping screws
  • Carrying profile (60mm)
  • Guide profile (27mm)

Preparatory workFirst you need to make a frame from profiles. For this, a preliminary marking is made on the ceiling and floor, along which the profiles will be placed. It is necessary to carefully check the location of the marking lines relative to each other. For this, it is optimal to use a plumb line. After marking and checking, the guide profiles are fastened to the surface using self-tapping screws.

Every 40-50 cm in the wall along a vertical line, again according to preliminary markings, holes are drilled that are necessary for installing dowels. Next, a supporting profile is installed, which is fastened to the dowels, as well as to the upper and lower guide profiles.

Before fixing the elements of the frame, it is necessary to check its geometry and the correct location of all its components relative to each other..

The space between the profiles can be used to insulate the room. It is filled with mineral wool and, in addition to obtaining a flat surface, the heat-saving characteristics of the room can be significantly improved.

Plasterboard installation. Before proceeding with this operation, it is necessary to make marks on the floor by which the location of the profiles will be determined. A drywall sheet is applied to the profile and mounted on it using self-tapping screws. Fasteners must be at least 15 cm apart. When performing installation work, it is worth making sure that the screw head is on the same plane with the sheet surface or not more than 0.5 mm below the surface..

Finishing works. After installing the drywall sheets, the joints are putty. To do this, you need to use a special gypsum-based building mixture. It is convenient for performing this event due to the increased level of plasticity..

To prevent cracks from appearing at the joints, the mesh is pre-glued, and a layer of putty is applied to it.

After that, you can wallpaper the walls or prepare them for painting..
