Advantages and disadvantages of gluing wallpaper on wallpaper
So, what can be considered an incentive for such a non-standard solution as re-pasting an existing wallpaper layer? There are few versions:
- you have little time to thoroughly clean the walls from the old layer;
- you do not have the skills and experience of leveling walls, and for this reason you do not dare to completely remove the old coating;
- you think that the next layer of wallpaper will make your walls warmer;
- you think you will save money by not doing a major surface cleanup.
We will deal with these theses in more detail. So how long does it take to remove the old coat? If these are ordinary paper or non-woven products - maximum half an hour.
Harder with liquid wallpaper - they need to be soaked and scraped off with a spatula. But this work will not take much time either. It is possible that in the process of cleaning the walls you will encounter an unpleasant reality: low-quality plaster will fall off along with the sheet of wallpaper. This is really sad.
This is not such an impossible task: there are many detailed master classes on the net that will help you quickly master this type of work. Here's about some wall insulation, then this thesis has some meaning. Indeed, multi-layer protection will help keep you warm. But if you really have a problem with cold walls, you need to solve it differently. The room should be insulated outsiderather than from the inside.
You have an apartment in a multi-storey building, and you won't be able to insulate the outside? Do it from the inside, but definitely not wallpaper... This is the worst insulation option. And the last one is the question of economy. The success of the event depends on many factors: how firmly the old layer "sits", how it reacts to wetting with glue and whether it can withstand the weight of the second layer. A small flaw - and your new expensive panels will go in ugly bubbles, or even completely slide down in folds. Then there will be no question of saving: get ready to buy everything again.
Options for gluing wallpaper on different types of coatings
If it was not possible to convince you to abandon the gluing of the second layer, we will consider in what cases it is possible and in which it is absolutely impossible to do this. Not every old coating can serve as the basis for a new one. It depends on the material that was used in the original finish.
Is it possible to glue wallpaper on non-woven wallpaper
Non-woven fabric is a thin cellulosic non-woven fabric. It is a highly elastic material and can be used if plaster on your walls is far from perfect. The non-woven coating is steam and air permeable and can be easily removed if necessary.
How to glue new ones, for example, vinyl wallpapers, for non-woven backing? To do this, you must carefully paint over the old PVA layer with glue or liquid glass. What it does: a moisture-proof film forms on the surface of the old layer. It will not let the glue layer pass through itself and will not let the old coating get wet and fall behind the wall.
Note! This method of gluing wallpaper will lead to the fact that the coating will not allow air to pass through. The repeated layer of wallpaper must not be painted, it will bubble.
If the old layer is liquid wallpaper
Paper or vinyl sheets cannot be glued to liquid cellulose. The fact is that the surface of this type of decorative coating is very embossed, and no even canvas will stick to it, and ordinary glue will soak the old layer, and it will fall off. Here you can try only the same liquid formulations... During the preparation process, paint over the old layer with white water-based paint.
The old layer of liquid decorative coating will have to be removed without fail if there are stains from grease or oil. If you leave everything as it is, the fat will show through the new layer already a couple of days after the repair.
How to glue wallpaper on wallpaper for painting
But to this question, how to glue wallpaper on wallpaper for painting, the unequivocal answer is no way. And there are two reasons for this:
- the embossed surface of the wallpaper for painting will not allow the new layer to adhere tightly to the wall;
- paintable coating has a vinyl outer layer that does not absorb moisture. This means that the glue will roll and not penetrate the surface, and the new layer will simply not stick.
Is it possible to glue photomurals on wallpaper
A full-wall photo is a fashionable touch in interior design. How beautiful to glue wallpaper:
- the base for them should be perfectly flat, especially if the drawing is applied on thin paper;
- there should be no bubbles or cracks on the base;
- the old layer of wallpaper should not contain water-soluble paint that can bleed through the new coating;
- there should be no relief on the old layer, it will ruin the drawing.
Otherwise, the pasting method is the same as described above. That is, you should make sure that the old layers do not go in bubbles, cover them moisture resistant paint or PVA glue.

How to prepare walls for pasting wallpaper on the old layer
The task of the preparatory work is to ensure high-quality fixation of the new decorative coating... In addition, during the preparation process, it is necessary to eliminate the fungus on the walls, if any, and the breeding sites of insects. It is problematic to do this without removing the old layer. Can you imagine how many bugs, ants and cockroaches can form colonies in areas of loose wallpaper?

Before you finish processing, do one small experiment: in one place, spread the glue with which you will glue a new layer and leave it to dry, if the base does not bubble and falls off, you can start working.
Why do you need a primer on the walls before gluing wallpaper
A primer is essential for better adhesion to the new layer. In hardware stores, you can find a large selection of primers for different purposes.
