Removing old wallpaper: is it necessary?
Before deciding how to stick wallpaper on wallpaper, you need to think about how much it needs. What if the old wallpaper has already become part of the wall and is not going to give up? There is a solution: you can stick new wallpapers on top of the old ones. But is it worth it to do it and is this method right for you? And if so, what mistakes should be avoided?
Advantages and disadvantages of technology
This technique allows you to save a lot of time and energy, since there is no need to level the surface of the base. Plus, saving money on dismantling the old coating and therefore the cost of the work will be much lower. It also attracts the opportunity to do the work yourself and not involve specialists.
But there are also negative aspects:
- You cannot fix wall defects;
- There is a possibility of poor-quality gluing of old and new wallpapers;
- Even if the wallpaper is well glued to each other, they can peel off from the wall, which reduces the service life of the entire coating;
- The option of peeling wallpaper from the wall surface is possible.
Such a misfortune may lie in wait for you: ridiculous air bubbles on the wallpaper just pasted. Most often, after two or three days the wallpaper will smooth out and the bubbles will disappear by themselves when the wallpaper is completely dry.
If the bubbles are small and few, you can use a heated iron. If it was not possible to smooth out the bubbles, then there is nothing to be done - the work will have to be done anew. And now you will have no other choice how to remove old wallpaper.
It becomes clear that such a "lazy" and cheap way to sticker wallpapers has drawbacks and there are many of them. In the event of any failure, the outcome is one: to dismantle everything that was able to stick and begin finishing work again. There is a forced cost overrun, which hits your pocket, takes your time and effort.
When gluing new wallpapers without removing old ones is allowed
Sticking some wallpaper on others is advisable subject to certain conditions.
So:
- Firstly, these are the requirements for previously pasted wallpapers. They should be thin enough and glued to the wall. In addition, the composition of the old wallpaper should have a completely paper structure, which will allow good absorption of glue. Otherwise, the old wallpaper must be removed.
- In turn, high demands are made on the quality of the glue. The technology for the preparation of glue must strictly comply with the instructions on the packaging. Before gluing new wallpaper, the surface of the old must be thoroughly saturated with glue. Only in this way is it possible to achieve the necessary degree of adhesion of two layers of wallpaper to the wall.
Attention: The most common mistake when sticking new wallpapers without removing old ones is inattention to the presence of coloring components on the surface of the impregnated material.
To detect their presence, a moistened sponge should be applied to the wall surface with an old coating and left for some time.If dye is present, it will be noticeable by staining the sponge. Then the surface of the wall will need to be treated with special sealant from stains.
When gluing new wallpapers without removing old ones is prohibited
In fact, all of the above conditions for the sticker of new paintings on the surface of old ones very rarely coincide.
When applying glue to the surface of old wallpaper with a volumetric pattern, a deplorable result awaits you:
- New wallpapers will not hold and their surface will become uneven.
- Using non-woven and vinyl wallpapers as a base for new stickers, the same thing will happen: a vinyl film will prevent the glue from absorbing properly. In this case, you are waiting for the gradual exfoliation of the wallpaper and in the end they still peel off.
- If the new wallpaper you are trying to stick does not let moisture pass, another problem awaits you. There is no air exchange through the surface of the wallpaper, moisture does not evaporate and the glue may lose its properties. As a result, the wallpaper will not hold.
Attention: For all its merits, the technique of stickering new wallpapers on old ones does not hold water. Of course, you decide. But in any case, it’s better to remove the old wallpaper and prepare the surface before the sticker.
