Aligning

  • Grind. Grinding can be quite a solid base, the level of which changes no more than 2-3 mm. In addition, it should not have significant defects. This removes the old coating and a small layer of plaster under it. For this, a simple tool is used: a bar around which sandpaper is wrapped.
  • Smooth with plaster. In the presence of significant curvature, the surfaces are plastered by beacons or finishes with plasterboard.

Important! After the leveling procedure, the walls must be primed and dried for six to seven hours.

  • Use sheets of plasterboard. The simplest and at the same time effective way, through which you can even even very curved walls.

  2. To level small projections and distribute the solution, use a narrow spatula.
  3. On the wall, apply a paint net and grind to the putty using a spatula.
  4. Apply to the mesh the starting filler with a 2 mm layer.
  5. Dry the surface for 5-7 hours.
  6. Mash the wall.

Important! Finishing putty is used to get rid of strokes, which leaves a coarse-grained trowel. Consistency in her - homogeneous finely dispersed, so the surface eventually turns out to be perfectly smooth. In addition, it does not absorb paint very much.

Finishing putty is applied just like the starting putty, but the layer will have a different thickness. The optimal thickness of the layer is 1.5-2 mm. When the surface dries, it needs to be sanded, using fine-grained sandpaper.

Priming

In order to prepare the walls for painting after the wallpaper was of high quality, the surface must be primed before applying the decorative solution.

How to get rid of paint?

And what should I do if I need to remove the paint itself? Cope with it is also quite difficult:

  • Sometimes in this case, use a metal brush with a short bristle. But it does not always help, since only the smoothing of the paint layer can occur.
  • Most often it is more efficient to use a set of nozzles, which includes scrapers of different shapes. For their independent manufacture, chisels, wide screwdrivers and spatulas are used.
  • To simplify and accelerate the process, use a special nozzle. It looks like a rod, on which short chains are fixed. It will be enough for several links. It must be inserted into the socket of the drill and clamped. The drill must be parallel to the surface to be cleaned. When the drill starts to rotate, with the help of chains, the paint will simply collapse.
  • Special chemical washings can also be used, but they must be used, observing all safety measures and instructions from the manufacturer. The effect of removing the old coating is quite fast.

Important! If the paint is to be painted again on the wall, it must be plastered beforehand.

It seems that painting the wall - it's very simple. In fact, this process will require preparation, which can take more than one day and consist of several processes. But still, such work is under the power of everyone, and you can do everything thanks to our advice.
