It may be a little disheartening, but it is not only our own taste that is decisive when choosing wallpaper, as the primary consideration is the wall and its insulation.
If, for example, the wall is soaking from below, or in block houses from above, it is worth taking preliminary measures in this regard. Regular waterlogging can naturally lead to the separation of the wallpaper. In block houses, leakage can be solved by insulating the apartment above us, so in this case it is only worth starting if the competent authorities can permanently eliminate this unpleasant problem. If the wall is soaking from below, it will certainly cost a significant amount to repair it, but without it it is pointless to wallpaper.
In many cases, waterlogging also leads to mold, which must also be permanently eliminated if we want our wallpaper to remain in place for a long time. There are several ways to do this, but it is advisable to seek professional advice. One of the options available to us, for example, is a mould remover that can be mixed into simple white paint, which can be very effective in this problem and can also provide an excellent basis.
If the above mentioned problems do not exist in our case, then we are partially lucky, but there may still be obstacles in the structure of the wall. Unless you have experience in this field, be sure to entrust the foundation and preparation of the walls to a professional. It is not worth saving on this, as the problem will come out later anyway.
It is possible to start wallpapering itself only after the necessary preparations, on a completely smooth, moisture-free wall. For the perfect result, it is worth having some experience, as it does not matter in which direction the wallpaper strips are glued and the quantity. It is important that it is sufficiently soaked, but not excessively. Of course, you can do this process yourself, but it doesn't hurt to read carefully and watch video tutorials on the topic. If we don't feel determined enough, we are left with a paver. In such cases, rely on the opinion of your acquaintances, as there are also professionals who give out sloppy work.
Wallpapering is definitely long-term, so it requires a number of preparations. Of course, with newer-built, well-insulated houses, it may not be necessary to spend time and money on such things.
