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:
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.
The material is easily detached from the wall without the use of any special tools
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.
All arising irregularities will have to be plastered again and carefully leveled
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.
Modern manufacturers offer a huge variety of insulation materials that are easy to install on the facade.
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.
Before deciding on re-pasting, examine the condition of the old layer.
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.
Non-woven coatings last several times longer than conventional paper
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.
For greater confidence in a high-quality result, add a little PVA or bustilate to the glue, and the new layer will securely fix on the old one.
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.
White - because this way, the color of old ones will not shine through the new canvases
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.

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? If there is any hint that the previous layer has moved away from the wall, ruthlessly remove it.
The resulting bald spots must be primed and lightly rubbed with a plaster mixture
After processing it is necessary polish the processing points fine sandpaper. In places where mold spots have appeared, you need to carry out the same procedure, additionally treating the wall with a composition from the fungus.
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.
For wallpaper, you should choose universal compositions.
The primer is applied only to a clean surface, therefore old coatings should be swept or wiped with a rag. Specialized primer in case of gluing the second layer wallpaper can be replaced with a layer of PVA glue. This will not affect the quality of adhesion.
