Therefore, it is worth starting with it.

So, we start, as usual, with the correct preparation. Competent preparation is of no small importance during repair. Therefore, it is worth starting with it. Gently remove the previous wallpaper or paint from the wall. Then align the walls, smear all the gaps and cracks available on them using putty. Remember that the surface of the walls of the room in which you started repairs should be perfectly smooth and even. This is the key to the fact that the wallpaper will hang on the walls relatively flat.
