Before you start repairing the walls, you will need to remove the old finish from them, and it is important to remove wallpaper so that there are no large pieces of material left on the wall. The cleaner you take off old wallpaper, the easier it will be for you to work with the surface later.
There are several ways to remove wallpaper from walls quickly, easily and simply. Sometimes people decide, as they say, not to bathe and glue new wallpapers right on top of the old ones. In no case should you do this, and there are a number of objective reasons for this:
- the surface of the wall will not look even, bumps and depressions will appear on it
- old wallpaper can peel off, and with them the new ones will fall behind the wall
Finally, mold often appears under the wallpaper, which can cause, for example, allergies. Therefore, the wall under the wallpaper must be thoroughly cleaned and processed, and this cannot be done without removing the layer of old finish.
It would seem that it can be difficult to get rid of the finish, why you need to talk in detail about how to quickly remove old wallpaper from the walls, because, if you twist the well-known proverb, rip off - do not glue. And yet, in fact, this work is not as simple as it seems.
List of required materials and tools
- Spatulas of different widths. It is better to sharpen them before work, as they must be sharp.
- Warm water, and ideally - a special liquid for removing wallpaper
- Steam generator. Of course, it is unlikely that you have this device at hand, but if you do have it, then it will help you out a lot, speeding up the process of removing wallpaper by half.
- A roller with needles or the so-called tiger for wallpaper
- Polyethylene film
- drywall knife
- masking tape
- Sponge with bucket or paint roller and tray
It is worth noting right away that the list of materials necessary for removing wallpaper may differ from the above - it depends on the type of finish that you are going to remove.
Room preparation
Before starting work, cover the room with some kind of protective material. In the process of removing the wallpaper, a lot of dust and dirt will fall on the floor. It is best to glue the plastic film to the baseboards using masking tape.
Also, do not forget to de-energize the electrical wiring, because it is most likely laid directly under the wallpaper, and you will have to wet the walls, as a result of which a short circuit may occur. Also seal all sockets and switches with adhesive tape, otherwise dirt may get inside.
We remove vinyl, non-woven and washable wallpapers
Vinyl-based wallpaper is the easiest to remove because it has a strong film applied to a paper backing. Just scratch this wallpaper, for example, with a knife, and moisten its entire surface. After some time, the liquid will destroy some of the glue, after which it remains only to cut the wallpaper and gently separate it from the wall by pulling on the edge.
In most cases, the wallpaper is separated in whole pieces. If small pieces of the paper layer remain on the wall after this procedure, then they must be additionally moistened and scraped off with a spatula.
Washable and non-woven wallpapers are removed in a similar way, as they are made of durable material. The only difference is that you will have to make cuts deeper and larger.
Ways to remove paper wallpaper
First way:
wetting with warm water
With paper wallpaper, things are much more complicated, because they cannot be removed in large pieces. In the process, they are torn, creating additional difficulties.
You can act according to a scheme similar to removing vinyl wallpaper: after making cuts and perforations of the finish, wet it properly with warm water, adding vinegar or any fabric softener to the liquid. Leave the wallpaper wet for about twenty minutes, and then use a spatula to remove large pieces of wallpaper.
The remains will also have to be scraped off with a spatula, constantly wetting the material. If you decide to remove wallpaper in a large room in this way, then you will have to sweat - the work will take a lot of time.
Second way:
use of special fluids
There is another way to effectively remove paper wallpaper. To do this, you will have to use special tools that penetrate the material faster and deeper than ordinary water.
Do not be afraid to use such substances indoors - they are completely harmless.
A special liquid is diluted with water, and then applied to the wallpaper. You don’t need to make any cuts, after a couple of minutes after applying the liquid, the adhesive layer will begin to collapse, and you can easily remove the wallpaper with a spatula.
You can make the wallpaper itself lag behind the wall - add a little bit of wallpaper glue to a special tool, apply it to the walls and leave it like that for several hours. Thus, the wallpaper will lag behind the wall in a solid piece.
Third way:
wallpaper removal with a steam generator
This method is suitable only for happy owners of a steam generator. The hot steam will peel off the wallpaper on its own, so it takes very little effort on your part to permanently remove it. By the way, with the help of a steam generator, you can shoot almost any wallpaper, not just paper.
In principle, you can do without a special device by simulating the action of a steam generator using a hot iron and a damp cloth. But this way of separating the wallpaper from the wall will take much more time.
Fourth way:
Removing wallpaper with a spatula and grinder
It is possible that the wallpaper in your room is glued with glue that does not dissolve from the liquid. Then you will have to arm yourself with a sharp spatula and a grinder (a drill with a metal brush nozzle) - and just peel off the wallpaper from the walls.
In the process of such work, a huge amount of dust is generated, so take care not only to protect the furniture and floor, but also to protect your own respiratory organs from getting dust into them.
How to remove wallpaper from drywall?
Remove wallpaper from plasterboard wall not easy, because the top layer of drywall is paper, and it is important not to damage it when removing old wallpaper.
You will have to use special tools that remove wallpaper paste. In this case, you will have to work very carefully, since a large amount of moisture can damage the surface of the drywall. When scraping off pieces of wallpaper with a spatula, be extremely careful not to scratch the surface of the wall.
If the wallpaper is glued to the drywall with a glue like PVA, that is, one that does not dissolve from moisture, most likely you will have to replace the drywall sheets along with the wallpaper. It is possible that the most reasonable thing to do is to do this from the very beginning - just remove the drywall along with the old wallpaper, if you are sure that the glue is resistant to moisture, of course.

Materials and preparations

You will need:
- spatulas - narrow and wide;

Removing paper-backed vinyl wallpaper
This wallpaper is a breeze to remove as it is just a vinyl film that is glued onto a paper backing.
Before removing, you need to scratch the wallpaper with a knife or a roller with needles, then wet it well with liquid or water and leave it for several hours so that moisture seeps under the polymer layer and destroys the adhesive.
A horizontal cut is made with a knife at the top - and the wallpaper is removed in whole strips when you pull them over the edge. However, pieces of the paper layer may remain on the wall. They also need to be moistened with water and removed with a spatula.
Removing washable and non-woven wallpaper
Since the former have a waterproof layer, in order for moisture to get inside, it is necessary to make cuts or holes. The same applies to the latter, which consist of synthetic fibers that are stronger than paper. After that, the wall is wetted with liquid.
After some time, the glue breaks down - and the wallpaper itself leaves.

But this is already a rather complicated and time-consuming procedure. This is because these wallpapers immediately torn, as a result, they need to be removed in small pieces. Especially the work is complicated by the presence of several layers of wallpaper.

Exists four ways to remove paper wallpaper:
Removing paper wallpaper from plasterboard walls
The difficulty lies in the fact that drywall is covered with a paper layer at the top, which must be left intact.
In such a situation, the most optimal way is to use not water, but special products that dissolve only wallpaper glue.
Special care should be taken when working with a spatula. It should be noted that if the wallpaper is glued to the PVA, then most likely you will not be able to remove it without damaging the drywall. So it's better not to waste precious time, but simply change the drywall plates.
For those who doubt their abilities, we suggest watching a video clip about the quick and easy removal of old paper wallpaper from the walls:
Here, in fact, are all the wisdom that you need to know when removing old wallpapers that have lost their former attractiveness. And then it all depends on your diligence, scrupulousness and speed of work. As they say, patience and work will grind everything!
With any repair, the first point is getting rid of traces of the old, including boring wallpaper. It is extremely important to remove the old coating from the walls, because it is possible only on a completely cleaned and leveled surface, ready for a “new life”. And if it is not so difficult to remove heavy vinyl or voluminous interlining, then how to peel off old paper wallpaper is a more difficult task, and clear instructions are needed to solve it.
Those who have had to rip off a vinyl or non-woven coating from the walls know that it is not so difficult - you just need to wet the canvas using a special technology, and the wallpaper will be removed quickly and easily entirely.
There are many ways to clean the walls of the old coating for a new finish.
With paper coating, the situation is more complicated - it is very thin, easily torn, and it will take a lot of time, effort and nerves to remove the wallpaper from the walls. The main thing is not to succumb to the temptation and not leave pieces of the old coating - this can nullify all further repair efforts.
Why can't you leave old wallpaper on the walls?
If you glue a fresh coating without removing the old one and without cleaning the surface, the wall will be covered with ugly bumps and pits. Especially strongly such a dubious relief will appear under a thin paper sheet, plain non-woven or vinyl “for painting”, silk-screen printing.
Important!
When you stick new wallpaper over the old ones, the weight of the coating increases, the old glue dissolves under the influence of moisture, and there is a big risk that the beautiful wallpaper will come off the wall along with everything that was on it, including plaster. The risk is especially great if during the previous repair the logic of the owners was similar, and several layers of paper have already settled on the walls.
When pasting wallpaper over existing ones, under the influence of wet glue, fungi and mold can form under the old paper. Not only are they seriously harmful to health, but they can also significantly spoil the appearance of the wall.
What you need to remove old wallpaper
Before clearing the wall of paper wallpaper, some preparation is needed. For "destructive" work you will need:
- a bucket of warm water or ready-made store-bought liquid to get rid of old wallpaper;
- a rag, sponge or foam roller (from 20 cm wide);
- a pair of spatulas of different sizes, always with sharp edges, or a special scraper;
- construction needle roller or wallpaper tiger - for perforating (piercing) a paper surface;
- steam generator, steam mop or powerful iron with hot steam function;
- masking tape and a large piece of polyethylene.
The process of peeling off the already obsolete paper coating is very dirty, so you need to protect the floor and sockets from pieces of wet paper and plaster. To do this, it is necessary to attach the film with adhesive tape to the skirting boards around the perimeter, seal the sockets with masking tape, and ideally also de-energize the room so that water does not accidentally splash onto the bare wires.
After all the preparations, you can proceed directly to peeling the wallpaper. There are several basic techniques, depending on the condition of the walls, your time, and the resources available.
You can remove old wallpaper with a spatula
Method One: Manual
To do this, simply take the corner of the old piece from below with your hand and remove the entire wallpaper. Remove the remaining pieces on the walls with a spatula or scraper. With this technology, there is one danger: the old canvas can be torn off along with the plaster, so cover your head with a cap or scarf and protect your nose and mouth from building dust with a mask.
Method two: plain water
Plain warm water is the most popular and effective way to remove old paper wallpaper in an apartment. To enhance the effect, you can add vinegar, the cheapest fabric softener or liquid dishwashing detergent to a bucket of water.
Then, with a roller, rag or sponge, we apply the liquid to small sections of the wall, wait 5-10 minutes for everything to be absorbed, and scrape off the paper with a spatula (scraper). Do not immediately pour water over the entire piece of the old roll - while you peel off one section, the thin paper will dry out and you will have to start all over again. If separate (small!) areas do not absorb liquid, you can try ironing them through a damp cloth with a hot iron - this will enhance the effect.
You should not overdo it either - if you flood the wall with water, this can soften the plaster and putty, and then the surface will have to be leveled and cleaned for a long time.
Method three: chemicals
If you want to know how to peel off old paper wallpaper the fastest and easiest way, you can take the advice of repair specialists and purchase a special liquid for removing old paper covering from walls.
Half a liter of such a product, depending on the brand, will cost about 200-300 rubles, and enough for 2-3 rooms, depending on the area. It is very simple to use: dilute in accordance with the instructions (for a greater effect, you can pour wallpaper glue), apply it to the walls and wait until it dries. Wallpaper liquid penetrates the paper and dissolves the glue, while the canvas itself remains intact. After drying, the pieces of the old roll move away from the surface entirely.
The use of such a tool will significantly save time - it will be possible to clean paper wallpaper from the walls with a scraper and a spatula in just a couple of hours. The only drawback is an unpleasant chemical smell, but it quickly disappears, and the “drug” itself is harmless to both people and pets.
On sale there are many chemicals that will facilitate the process of removing old wallpaper from the walls.
Method four: hot steam
If you don’t want to spend money on a cleaning agent, but you have a steam generator or a powerful iron at home, it will be much easier to tear off the wallpaper.
First, provide access to the outlet: if you have de-energized the room and closed the sockets, you can bring an extension cord from the next room. Then we process the wallpaper pieces one by one with hot steam and wait 3-5 minutes. Paper and old glue swell quickly when exposed to hot, moist air, and it is not difficult to remove the old coating.
Method five: special tools
If several layers of paper have accumulated on your walls or a two-layer wallpaper coating (duplex) was pasted during the last repair, it will be very problematic to remove the wallpaper. Too old wallpaper glue, PVA or bustilat can complicate the process even more. Dissolving such a mixture is quite difficult, and you will probably have to scrape everything by hand.
For these works, you will need a roller with needles or a more gentle tool - wallpaper tiger. The tool must be walked over the entire surface to make holes, moisten the wallpaper with hot water: in this case, the liquid quickly penetrates under the paper. Pieces of the old canvas are torn off with a sharp spatula or scraper, but you have to be careful: the sharp edges of the tool easily leave grooves and dents on the wall, and then you have to further level it.
If liquid and perforating tools are powerless against the wall covering, you can use more serious equipment: a drill with a wallpaper stripping nozzle (round brush) or a grinder with a coarse-grained brush. Such work is very dusty, and the wall can be significantly damaged - leveling the surface with putty is inevitable.

How to get rid of paper wallpaper on drywall
If you need to remove the paper coating not from an ordinary wall, but from drywall, you need to go to business delicately. Drywall is covered with a thin paper layer that cannot be torn or scratched.
The best option in this case is to use a chemical tool to remove old wallpaper pieces or hot steam. Experts do not recommend using water here. If the old wallpaper is very thin, smooth and stuck to the drywall tightly, you can prime and glue new ones on top. It is better to use embossed foam vinyl for this, which will hide possible irregularities.
There are a lot of ways to peel off old paper wallpapers from the walls, and choosing the right one will not be difficult. But if you got a very problematic apartment, and the old coating just merged with the wall, you can use the services of professionals. Today, craftsmen have many special tools, and they can easily remove all the former beauty from the walls without damaging the surface.
When making repairs, you need to know how to quickly remove old wallpaper from the walls. This is not at all difficult to do if you follow simple recommendations.
The trowel removal process is sometimes extremely simple
Traditional ways
Smart tools greatly facilitate the unpleasant and time-consuming process
As you know, all wallpaper stretches when dry. Therefore, any unevenness, roughness can cause the backlog of their base. In addition, if the wall is covered in dust and has spots on the surface, there is a good chance that all this will be on the new coating. Agree, a stain or smudge that appears will not decorate the room after repair. You can't be sure that the new wallpaper sheets will stick well over the old ones. Water-based adhesive, softens the old layer unevenly. As a result of this, bubbles form in one place, and the coating will be firmly adhered in another. To avoid such a defect, it is better to play it safe by completely cleaning the wall.
Look for an old tag or roll label. It must show symbols that indicate the type of removal: “Remove without residue”, “Remove wet”, “Delaminate when removed”, “Embossing does not deform”, “Double with top embossed layer”. If there is no label left, then you can use universal methods.
The scratches caused by the “wallpaper tiger” make them much easier to remove
For a quick process of removing the old repair, prepare two spatulas: narrow and wide. It is important that their edge is sharp, so it will easily enter into the joints. The edges of the spatula can be sharpened with emery. You will need a special liquid, but you can use ordinary warm water. A household steam generator (steam mop) can greatly facilitate the work. To perforate the surface, you need a knife, a wallpaper tiger or a roller with needles. As auxiliary materials, you may need masking tape, plastic wrap, a drywall knife, a sponge and a bucket, a paint roller 15-25 centimeters wide. The list of tools will differ depending on the scope of work and the type of wallpaper.
Before starting work, take care to protect the floor from wet and sticky pieces of paper. To do this, glue the plastic film to the baseboard around the entire perimeter of the room. It is best to do this with masking tape, as it holds well, and does not leave marks when peeled off. Switches and sockets are also recommended to be sealed with masking tape so that water does not get into them. Having prepared the room, you can get to work.
Wallpaper removal technology
Before removal, you can use a spiked roller
It is more hygienic to remove wet. So dust will not form, and with a strong layer of old glue, the plaster does not crumble, it is easier to remove glue residue from the wall. For wet removal, a special solution is required. After application, the wallpaper is removed from the surface without difficulty. Tap water can be used for quick removal. Wet them with a garden sprayer or sponge. The liquid should be well absorbed. If necessary, repeat the procedure. Wait approximately 20 minutes. During this time, the water should soak the dried glue, the wallpaper will easily lag behind the surface. Places where they have not lagged behind must be moistened again.
If you do not moisten too much, the water will quickly soak in, dry out without having time to soak the glue. And if the surface of the canvases is wetted very abundantly, then the liquid flows onto the floor, which is why the surface of the walls does not have time to get wet, as it should. Soak the canvases gradually, moving from one place to another, periodically checking how far the finishing material has moved away from the wall. It is better to tear off from the seam. If they dry out, wet them again. Particular care is needed when removing old wallpaper around sockets, switches, electric meters, knife switches, and other electrical equipment. Observing safety precautions, turn off the power supply, then loosen the fasteners.
Roller with spikes and a long handle is used in hard-to-reach places, in rooms with high ceilings
In order to work faster, use not cold, but hot water. Separate pieces of old coatings will need to be removed with a scraper. Do this carefully so as not to damage the top layer of plaster. In order for moisture to better penetrate to the paper base, small scratches and cuts should be made on them. A wallpaper tiger is best suited for this. This tool allows you to quickly perforate large areas, thanks to the soft wheels, putty or plaster is not damaged. After removing the canvas, no scratches remain on the wall. Compliance with simple tips will help speed up the work on the internal repair of the premises.
How to remove non-woven wallpaper
They consist of durable synthetic fibers, have a waterproof layer, so cuts or holes must be made on the surface. After that, the wall is wetted with water using a sponge or spray. After 15 minutes, the glue swells, the wallpaper begins to move away from the wall.
How to remove vinyl wallpaper
Vinyl wallpapers are usually easy to remove, but making sure the surface is thoroughly cleaned is still necessary.
These are very easy to remove. The covering represents the strong vinyl film connected with a paper basis. To remove them, you need to scratch the surface with a knife, spatula or wallpaper tiger. When enough cuts appear on them, moisten with water, wait 15-20 minutes. During this time, moisture will penetrate under the polymer layer, dissolving the adhesive. Then make a horizontal cut at the top, separate the edge by gently pulling the canvas. Polyvinyl chloride is a durable material, so the wallpaper does not tear into pieces, but is separated by solid strips. If fragments of the paper layer remain on the wall, they must be moistened and removed with a spatula.
Sometimes vinyl panels can be heavy, making removal difficult. In this case, it is better to remove them in layers. You will need a wallpaper tiger, a metal brush, a needle roller. After removing the moisture-resistant protective layer with a tool, you must use a film remover equipped with self-sharpening discs. The device, in contact with the wall, perforates the outer layer without damaging the wall.
How to remove washable wallpaper
They are made up of two layers. The top one comes off pretty easily, while the bottom one stays firmly glued to the wall. The panels are not afraid of moisture, so removing them in a simple way (soaking) will not work. You will need a toothed roller or scraper. Using tools, make notches, and then moisten the entire surface. Water must penetrate well under the coating. Wait a while, try to remove them. If the water has not soaked the adhesive well, use a steam remover. After steaming one area of the surface, press the steam soleplate against another. For quick removal, you can use a conventional steam iron, which will replace your steam generator.
How to remove liquid wallpaper
The successful removal of liquid wallpaper by hand is based on pre-abundant wetting and subsequent thorough rinsing of the old coating.
Don't rush to peel off this long-lasting all-purpose coating. Perhaps it will be enough just to repaint the room with water-based paint. But if you decide to take them off, first you need to figure out what kind of canvases they are. They can be "reusable" with pieces of rayon that are easy to soak. If they look like decorative plaster, use an industrial hair dryer or grinder. The disadvantage of an industrial hair dryer is low performance and high energy consumption.
You can remove them manually. This requires warm water, a scraper and a spatula. Having soaked them well, you can proceed with dismantling. You can facilitate the work with a proven method: add Ceresit ST-17 primer to the liquid and apply to the surface. After 5-10 minutes, you can begin to remove with a spatula. If bumps remain on the wall, putty the wall.
How to remove wallpaper on drywall
Wallpaper of any type can be removed using chemical products that save time and effort
Drywall is used for interior decoration. Thanks to him, you can even out all the defects and irregularities. But, it has a drawback - it is difficult to remove old coatings from it.
The process of removing canvases from drywall is quite complicated. Drywall is covered with a paper layer on top, which must not be damaged. If putty is applied, it is best to use chemicals that dissolve the wallpaper paste. Do not use large amounts of water as this will damage the outer layer of drywall.
One of the most convenient ways is cheap glue. Dilute the cheapest wallpaper paste, apply on the wall. It dries for a very long time, as a result of which the materials swell, pull back. Now they can be easily removed with a spatula. In some cases, a primer is used. It impregnates paper well, does not evaporate as quickly as water. Using this method, you will also prime the surface. When removing adhesive residue with a spatula, be extremely careful not to damage the drywall sheet.
How to easily remove wallpaper from several layers
Sheets glued with high-quality glue in one layer are easy to remove. But what about old paper wallpaper that has been pasted several times? Wet the surface well with hot liquid before starting work. It is better to do this not with a spray, but with a sponge or rag. Wet them gradually, one at a time. You do not need to immediately pay attention to the whole room, because. during this time, the walls will have time to dry, and excessive moisture can damage the plaster layer.
If some areas could not be removed, use a special tool. Zinsser, ATLAS ALPAN, QUELYD DISSOUCOL have proven themselves to speed up the adhesive removal process. Wallpaper remover is effective and safe.
