Prepare the substrate for a non-woven wallpaper
Good non-woven wallpapers are unfortunately not cheap. All the more annoying when you discover bumps or shadows after wallpapering that shine through the new wallpaper from the underground. But you can take precautions against this.
Non-woven wallpapers are often slightly translucent. So that this property does not lead to a poor result for the newly wallpapered wall, the Underground be prepared accordingly.
Translucent or not - this is how you can tell from the non-woven wallpaper
- Imagine yourself window and hold a layer of the new wallpaper against the light.
- Place your hand behind it. If you can see this behind the non-woven wallpaper, it is unfortunately so thin that you have to pre-treat the surface before wallpapering.
Prepare the substrate for the non-woven wallpaper
The lighter and more translucent the new wall covering, the more carefully you have to be when preparing the substrate. Every unevenness and every dark spot can shine through, especially through monochrome non-woven wallpapers without a pattern.
- Carefully and completely remove the old wallpaper.
- Fill all dowel holes as smoothly as possible. In doing so, you should not only pay attention to new holes, but also check older repairs and, if necessary, improve them.
- To compensate for unevenness in the plaster, apply a filler compound over a large area, smooth it out with a smoothing trowel and allow the surface to dry completely. Then carefully sand them smooth by hand or using a sander.
- Then delete the walls with a primer. Various companies have special products for the pretreatment of the surface of non-woven wallpapers.
- Such a product, also known as a wallpaper base for non-woven wallpapers, evens out color differences on the wall. These arise, for example, on the filled areas, which you can prevent showing through.
- By priming the substrate, you also regulate its absorbency, which is extremely important when wallpapering. If the wall absorbs the moisture from the wallpaper paste too quickly, smooth wallpapering is a real challenge. If, on the other hand, it sucks too little, there is a risk that the wallpaper will peel off again. In both cases the effort has been in vain and the result is disappointing.
Wallpapering with conventional paper wallpapers can be quite nerve-wracking. Man ...
Even if the preparatory work for the Wallpapering can take a lot of time, you should give them due attention. So you can be sure that the professionally wallpapered wall will look flawless later.
