It is not difficult to remove the old finish, applied with ordinary wallpaper glue, from a plastered surface. It is more difficult to deal with thin paper wallpaper glued with PVA or paste. To ensure that removing old wallpaper from walls does not cause you any trouble, we will consider options for dismantling the main types of finishes on paper, non-woven, liquid base, as well as with vinyl coating.
Getting rid of Soviet wallpaper - water and special tools
The most difficult thing is to remove old wallpaper from Soviet-style walls, and everyone who has tried to do this at least once will agree with this statement. There are several reasons for this. The structure of the wallpaper, the use of durable CMC, Bustilat, PVA wood glue, which “tightly” glue the rolls. It is impossible to rip off the wallpaper in one piece; it peels off in small sections. The dismantling process is complicated by old wallpaper pasted on top of each other in several layers and on newspaper. This finish has to be removed in layers.
To quickly remove old wallpaper from walls, prepare the following set of materials and tools:
- dishwashing detergent or liquid soap;
- sprayer or bucket of water;
- foam sponges;
- wallpaper tiger;
- needle roller;
- spatula with a sharp blade;
- masking tape;
- polyethylene film.
Before removing wallpaper, take care of the safety rules. Turn off the electricity in the apartment, cover sockets and switches with masking tape to prevent water from entering. Also insulate protruding wires. To make cleaning easier, glue plastic bags at least 0.5 m wide along the baseboard, which are usually used for packing things and furniture. Cleaning after dismantling will be faster, the floor will not be splashed with water.
Take a spray bottle or bucket of water and add a couple of drops of dishwashing liquid or soap. Moisten small area walls and wait 10–20 minutes until the water and degreaser are absorbed into the base and soften the adhesive. To make the wallpaper swell faster, it is better to use hot water rather than cold water. Soak the area gradually. Repeat wetting as it dries, do not try to moisten the wall abundantly at once. For better penetration of water into the layer, use a knife. Make several longitudinal notches.
IN hard to reach places and on the ceiling, use a needle roller to make slits. Alternative option A wallpaper tiger will be used to make scratches. This tool allows you to process a large layer of wallpaper without damaging the concrete coating and plaster, thanks to the soft rollers.
We begin to tear off the wallpaper from the corner of the room, from top to bottom. We clean the finish with a sharp spatula, preferably with long handle. We act carefully around sockets, switches and other electronic devices, using a narrow spatula.
Washing and steaming - dealing with difficult wallpaper
Modern manufacturers have come up with means that make it easy to remove old wallpaper - chemical removers. Among famous brands QUELYD DISSOUCOL, Zinsser, ATLAS ALPAN are popular on the market. They penetrate deeply into the structure of the wallpaper and destroy the adhesive layer. Applying the remover does not cause any difficulties. We dilute the composition according to the manufacturer's recommendations, distribute the liquid evenly with a sponge or through a sprayer. After the finish has swollen, it can be easily removed along with all the remains from the wall.
Another effective option dealing with difficult wallpaper - steaming. For these purposes, you can use a steam mop or steam cleaner, and if you don’t have them at hand, a regular iron and a wet cloth will do. Turn on the steam mode, place a wet cloth against the problem area of the wall and direct steam from the iron through it. Under the influence of steam, the glue will collapse, and you can quickly tear off the old wallpaper from the walls. Just need to do this while they are still hot. We clean off the small pieces remaining after steaming with sandpaper, a metal scraper or a grinding machine.
Finishing on non-woven backing - how to deal with it?
The main advantage of wallpaper on a non-woven basis is the backing, which can not be torn off from the wall, dismantling only the top layer. It strengthens the wall and ensures that the new finish adheres well. If you still want to completely clean the walls of old wallpaper, follow the following instructions.
We take a wide sharp spatula, pry up the edge of the canvas and pull it from top to bottom. Remove the remaining pieces in hard-to-reach places with a narrow spatula. If the canvas does not lift well, tear off the wallpaper, wetting the area with warm water. To allow water to penetrate deeper into the base, we use wallpaper tiger. After 15–20 minutes, the non-woven wallpaper will swell. The soaked finish is simply removed with a scraper or spatula. If this is not enough, add a couple of drops of dish soap to the water and re-wet the area that is not lagging with water.
Features of dismantling a washable coating
Vinyl or washable wallpaper, two-layer. They consist of a paper or non-woven base, which is attached to the wall covering, and covered with vinyl on top. It prevents moisture from getting under the wallpaper and allows you to wash the finish when it gets dirty. It is not necessary to completely remove washable non-woven wallpaper; it is enough to remove only the outer vinyl layer. However, if the base begins to come off, play it safe and remove the entire finish.
It will not be possible to remove washable wallpaper by simply wetting the surface with water. Vinyl coating is resistant to moisture, and to remove it you need to make notches on the surface of the material using a needle roller or scraper. Only after this do we wet the area. When the water penetrates well into the base, the finish will begin to bubble and removing the washable wallpaper from the wall will not be difficult. If any area is difficult to remove, use a steam mop or iron. After steaming one area, we move on to another, prying up the remaining finish with a spatula until it cools down.
We remove liquid wallpaper and reuse it
It's easy from the walls. They quickly soak under the influence of moisture, leaving no marks on the surface. If you do not paint and varnish and other decorative coatings, after dismantling, dry them and use them for decoration in another room. Liquid wallpaper with impurities of varnish and paint are completely recycled and are not reused. Depending on the final finish, this coating can be removed in several ways. If you covered the surface liquid wallpaper varnish or paint, then use a hair dryer or a grinding machine with an attachment to remove it from the surface. In the absence construction hair dryer use a regular household hair dryer. True, work with him will take a long time. A steam iron will also be effective in removal.
Standard liquid wallpaper without coating is removed using the familiar method using warm water, a metal scraper and a sharp spatula. To increase work efficiency, we recommend adding a couple of capfuls of Ceresit ST-17 primer to the water. After wetting the surface, leave the composition to soak for 10 minutes, open the windows and doors to create a draft in the room and speed up the process. The layer has swollen and softened, we peel it off. We clean off small residues of liquid wallpaper with a scraper and sand the surface with sandpaper.
Removing the trim from drywall
Plasterboard partitions are increasingly found on construction sites and residential buildings. The peculiarity of removing old coating from drywall is to be careful when handling the coating. If the top paper layer is damaged, drywall loses its quality characteristics. To easily peel off the wallpaper, we recommend chemical removers that penetrate deeply into the adhesive structure and allow the base of the finish to quickly peel away from the surface. This method is especially advisable if the drywall is puttied and you do not want to damage the leveling layer with sudden movements of the spatula. If there is no primer on the walls, the use of a chemical remover will also best option. To quickly remove old wallpaper from drywall, scratch the surface with a needle roller or wallpaper tiger before applying chemicals.
Alternative and budget option removing wallpaper from plasterboard partition– applying cheap wallpaper glue to the finish. Due to the fact that such glue dries for a long time, the wallpaper swells, begins to bubble, stretch and lag behind the surface. Carefully pry up the torn layer with a sharp spatula, and use a painting knife to work in hard-to-reach places.
A primer is also suitable for impregnating wallpaper. Compared to water, it evaporates more slowly, therefore, it affects the material longer and penetrates deeper into the structure. After soaking, remove the finish with a metal scraper or spatula. Having finished dismantling, we check the walls for irregularities. If necessary, remove small residues with sandpaper, putty and prime the surface.

We have collected several effective ways to remove old wallpaper from walls quickly and easily, be it paper, vinyl or washable canvas.
Why is it better not to glue new wallpaper onto old ones?
In the old days, when wallpaper was all paper without any protective films and coatings, gluing new wallpaper onto the old, smooth, undeformed, but simply boring, coating could be done with clear conscience. Sometimes there are so many layers of old wallpaper that from them, like tree rings, you can determine the number of repairs and remember different periods in the life of the owners. If on top of the old Soviet ones and miraculously survived paper wallpaper If you are going to glue it again, then you can take a risk and do without the dismantling procedure. In all other cases, it is better not to do this.
Firstly, if you are planning, or any other finishing, then the layer of old wallpaper must be removed without fail. Secondly, even if you are going to glue wallpaper again, then when applying one layer to another you can get lag of the new layer, wrinkles, blisters and other defects. This happens because the old layer may no longer hold on very well, and there is also an increased load. Moreover, the glue you will use will soften the old layer of wallpaper. As a result, the drying process will be delayed, and if the wallpaper in two layers is of different quality, then the lag from the walls cannot be avoided. 
- It’s great if you still have labels from the rolls that indicate the type of dismantling, for example, “remove wet” or “delaminate when removed.”
- Before you start removing old wallpaper, remember how it was applied. If it was one that was applied to, then most likely the entire dismantling process will not be very difficult.
- Problems may arise if the wallpaper was glued with a non-standard glue, for example, PVA, or was mounted on an unsuitable surface. The most difficult surface is considered to be unputtyed drywall.
- Some difficulties may arise if the top layer does not absorb moisture (vinyl and washable wallpaper), but effective methods have been invented for this case as well.
In any case, remember that nothing is impossible. There are many ways to remove old wallpaper from walls; you just may have to put in a little more effort than planned.

No. 9. How to remove washable wallpaper?
No. 11. How to remove wallpaper from drywall?
Many people complain that the old Soviet paper wallpaper is literally ingrained into the walls and cannot be removed either with water or steam. If all methods have been tried, and some of the wallpaper remains firmly glued to the walls, then such a half-prepared wall can be puttied to level the surface for subsequent finishing. If the remnants of the old wallpaper are held tightly, tightly, then there will be nothing for them under the putty, and they will not affect the new coating in any way.
Treating walls after removing wallpaper
When all the work is completed and the walls have been cleared of the last piece of old wallpaper, it is time to assess the condition of the surface. In most cases, part of the plaster is removed with the canvases, so the wall is unlikely to be able to boast of perfect evenness. Before starting finishing, its surface must be carefully prepared.
Previously, there was a misconception that there was no particular need to bother with preparing the walls for. Alas, there are still fans of this opinion. It’s not hard to guess that as a result of this approach they don’t get much high quality finishing, even if you choose high-quality wallpaper. An unprepared wall contains something that even the thickest wallpaper cannot hide. This surface is more porous, which means that much more wallpaper glue will be used, and adhesion will be worse. Cracks on walls in contact with the street can even cause mold to develop.
Whatever the subsequent wall decoration(wallpaper, painting, decorative plaster etc.), The list of surface preparation activities will be approximately the same:
- primary priming of walls necessary to improve the adhesion of the finishing material to the wall, reduce the degree of moisture absorption (saving paint, glue), and speed up the drying process of the putty. apply, in hard to reach places you can use a brush. If you see that somewhere the composition is absorbed into the wall literally before your eyes, it is better to apply a second layer;
Glims DeepPrime primer Glims DeepPrime primer is a primer that allows you not only to strengthen the base, improve adhesion and save paint or glue, but also protect the surface from mold and mildew due to the antiseptic included in the composition. The primer can be applied to almost any surface, it dries quickly (4 hours) and has low consumption (0.08-0.2 kg/m2).
- plaster not always necessary. If the surface of the wall does not contain deep holes, drops and other defects, and you plan to hang fairly thick vinyl or non-woven wallpaper, then it will be enough to putty some of the unevenness. If the defects are significant, thin wallpaper or painting will be used, then you will have to use plaster first. For brick walls a cement-sand composition is used; it is more suitable for concrete gypsum plaster. Most convenient to use ready-made mixtures which only require adding water. The technology of plastering walls is dedicated to;
- putty It’s better not to neglect it. It allows you to reduce the roughness of the walls, perfectly level the surface, which will have a positive effect on the quality of subsequent finishing. . If you do all the work yourself, it is better to take a gypsum composition - it is easier to apply than cement. The putty is applied with spatulas, and the finishing layer does not need to be applied if thick wallpaper is glued, decorative plaster is applied or ceramic tiles are installed;
- re-priming will allow you to finally prepare the surface for subsequent finishing. This time the composition should be much smaller.
Remember to let each coat you apply dry thoroughly. Data on complete drying time will be indicated on the packaging.
Most people don’t bother with this at all, but glue new canvases directly onto the old wallpaper, which absolutely should not be done.
Firstly, if you have old wallpaper or the slightest fragments of it, the wall surface will never be ideal. In other words, immediately after pasting the new wallpaper, as they say, all the irregularities and bumps will be visible.
