What can be cooked from squid: quick and tasty

They get bored or out of fashion and it's time to replace them. Before sticking on the new ones, you need to get rid of the old ones, then prepare the surface of the walls for pasting with new wallpaper and only after that start replacing.

What to do if the wallpaper was glued to drywall, how to remove it correctly - you need to consider in more detail.

To apply new wallpaper, it is necessary to properly prepare the surface.... If there was already wallpaper on the walls, you need it (find out how to easily and quickly remove it from the walls, and). Otherwise, the new ones will lie unevenly, will shine through or will not hold at all. If the repair did not remain from Soviet times, when all wallpapers were made exclusively of paper, then the old covering must be removed in any case.

Another argument “for” removing old wallpaper - no matter what material they are, they hung on the walls long enough to absorb dust, odors, and somewhere dirt and pathogenic microflora (and how to get rid of it? ). And all this can be "transferred" to the new wallpaper.

Pasting on old wallpaper will not only entail an overconsumption of glue, but also significantly increase the risk of peeling, dampness and the appearance of fungus.

With the help of what and how quickly and easily it can be done?

Removing wallpaper from drywall is complicated by the fact that most often such walls are not treated with putty (?) Before pasting. And since drywall itself is inherently also paper, albeit construction paper, the adhesion of materials increases significantly. At the same time, the option of simply soaking old wallpaper for removal is also not considered.

To get started, you need tools: a wallpaper tiger (a tool with one or more studded rollers for piercing wallpaper), a spatula, a sponge and warm water.

There are two main options for getting rid of old wallpaper from a drywall surface.:

Steaming(with a construction steamer, in the absence of such a household iron with a steaming function).
Using wallpaper remover(with increased permeability, affects only the adhesive, but not the wall surface).

But both of these methods are not completely universal. Still, it is necessary to take into account the features of this or that type of wallpaper.

Non-woven

If we go from the opposite, then non-woven wallpaper (?) Is most suitable for pasting drywall. Especially if the putty stage was skipped in the process. When removed, the non-woven wallpaper delaminates and leaves, together with the old glue, a thin, even bottom layer, which is quite suitable as a basis for a new layer.

But the method of removing such wallpaper with plain water is not suitable. The permeability of non-woven wallpaper is quite high - almost like that of paper.

If the plasterboard walls were previously plastered, then there will be no problems with removal - you can safely use:

dry way- the wallpaper is separated from the base, the base is either left or removed with a grinder (requires utmost care);
removal with special formulations- they impregnate only the adhesive layer, without affecting the drywall.

Often non-woven wallpaper can be covered with a top vinyl layer, or used for painting. In both cases, a moisture impermeable layer is present on the surface. In such cases, preliminary piercing of the surface will help.

Vinyl

Vinyl wallpaper is more difficult to remove from drywall due to its moisture resistance. You can apply the same approach to them as to non-woven ones, but to soak the top layer, you need to make punctures all over the surface so that special solution could get inside.

When soaking the top layer, it is also not recommended to use clean water - it is better to take a weak adhesive solution, then it will soak the base of the wallpaper, but more slowly penetrate to the drywall. But it is necessary to apply such a solution several times - it depends on the density of the wallpaper.

The softened top layer is easily separated by a whole layer... It is enough to pick up the edge under the ceiling with a spatula and pull it down. If there are still fragments on the drywall, the procedure must be repeated with them.

All these methods will be effective if vinyl wallpapers were glued on a special glue for such wallpapers. If PVA glue was used, it is no longer possible to remove them, it will be necessary to replace the drywall sheets.

Read more on how to remove vinyl wallpaper from walls.

Washable

Removing washable wallpaper will also require mortar and surface piercing. They also contain a water-repellent layer. The algorithm for removing them will be the same as in the case of vinyl wallpaper.

Another option to get rid of old washable wallpaper is to dry it. If the wallpaper lends itself - they need to be stratified... Then the procedure will be greatly simplified.

Paper

The method of soaking with water is easily applicable to paper wallpaper. After that, they can be easily removed, but this cannot be done quickly. Small pieces will constantly come off, which will need to be scraped off with a spatula.

Also, when working with drywall, you need to carefully monitor so that there is no excess of water, do everything quickly and soak the wallpaper in separate strips so that the remaining areas do not have time to swell with the drywall.

You can speed up the process. To do this, you need to note the time during which the strip manages to get wet and begin to flake off, without affecting the drywall. Taking it as the maximum, start soaking the next strip in advance, and so on.

With double-layer wallpaper, everything is much easier - it will be enough to peel off the top layer from the bottom one. And glue the new wallpaper directly onto it.

Liquid

Liquid wallpaper belongs to the type of water-repellent(about the pros, cons and rules for applying liquid wallpaper we told c). When removing them from drywall by the soaking method, you need to be extremely careful - you will also need surface perforation and quick accurate work with a spatula. You can also use a steam generator (with what can you?).

But it is still better to use a mechanical method - remove liquid wallpaper using a grinder with a large abrasive.

When working with such a machine, a lot of dust will be generated., you will need a respirator and goggles. To save energy and money when working with plasterboard surfaces, you should choose a different type of wallpaper.

How to remove correctly without putty?

Saving time, effort and money on preparing drywall walls for wallpapering is ultimately much more expensive.

To get rid of the risks of ruining gypsum plasterboard walls once and for all, it is better to abandon all methods using water, if the wall has not been previously putty. But, if you work correctly, you can use different ways.

Soaking method... Depending on the type of wallpaper, the surface is perforated, soaked and removed with a spatula. The main thing is to monitor the amount of water, act quickly and accurately, without waiting for the drywall to get wet. The maximum waiting time for soaking is about 10 minutes. For waterproof wallpaper, it is better to use a weak solution of water and glue, the soaking time will already be slightly longer.
Use of special solutions... Wallpaper will flake off more effectively if the glue is softened. For this, there are special chemical solutions that penetrate deep into the wallpaper, liquefy the glue, but do not damage the drywall. The liquid is applied for 15-20 minutes.
Steaming method... Special steam generators are used for it, and in their absence, household irons with a steamer. You need to hold the device for an average of 10 seconds. After that, the wallpaper comes off perfectly.
Mechanical method... Suitable for tricky cases and the most durable wallpapers. You will need a sander to remove wallpaper. With its help, you can, as it were, grind off old wallpaper.

To work with drywall, the use of a toothed roller is contraindicated, otherwise it will not be possible to remove the coating without damaging the wall. It will make holes too deep and damage the drywall itself. Only a special device is suitable here - a wallpaper tiger. In this case, you need to constantly monitor the pressure on him.

The first thing to do is to prevent the problem - don't skimp on. This will help avoid many problems in the future.
For pasting wallpaper, you need to use only glue that matches a particular type of wallpaper.
Do not use PVA glue. It is almost impossible to remove it from drywall without damaging the surface.
Iron and water are the most budgetary and quick way removing old wallpaper, even in the case of drywall.
In especially severe cases, even experts recommend using old ones (waterproof ones must be pre-treated in order to increase adhesion).
Contrary to popular belief, soaking is much less likely to ruin drywall than dry peeling. This will tear off the top protective layer.

Knowing the nuances of working with drywall, you can not only successfully paste over it, but also relatively painlessly remove boring wallpaper yourself and relatively easily, without resorting to the help of professionals. It all depends on the type of wallpaper, as well as the time and money that can be spent on the process. And the choice of methods is great, the main thing is to follow all the rules.

The result will depend on the quality of surface preparation. finishing works... GKL is a reliable and sufficiently durable material, but carelessness in actions while removing old coatings can lead to chips, scratches and deform it; it also negatively tolerates moisture.

By its structure, drywall is a pliable and even building material, on the surface of which a fresh layer of paint or wallpaper easily falls, even if you do not remove the old one. But irregularities, bubbles and bulges may appear.

In rooms with high humidity, various microorganisms, fungi and mold often appear, which not only spoil appearance, but also unsafe for health. They are the cause of respiratory diseases. Therefore, before applying new ones, it is necessary to remove the old wallpaper, and treat the infected areas with an antifungal compound.

Dismantling the wallpaper glued to the gypsum board

Before starting, it is important to find out what type of glue was used for pasting, and whether a putty was applied. In the case of using busylate or PVA, it is unlikely that it will be possible to preserve the entire surface of the drywall, especially for thin paper wallpaper.

If the old coating is very durable, it is simply primed and glued with a denser structure - vinyl or non-woven wallpaper. When the canvases have been applied using modern adhesives, they are pre-soaked in warm water, to which a little primer or glue is added - this will improve water penetration. After some time, carefully remove the paper layer with a spatula.

Preparatory work

Prepare the following tool:

narrow and wide spatula;
molar roller;
needle roller or "tiger";
molar scotch;
wallpaper knife;
PVC film;
water tray, spray bottle;
household steamer;
garbage bags;
stable stepladder.

In each case, the process of preparing the premises will be the same.

To exclude dirt and damage to the floor, it is covered with old newspapers, and covered with plastic wrap on top.
Take extra care when cleaning walls near switches and outlets. First you need to turn off the power, and then unscrew the screws to remove the paper under them.
The sockets are sealed with molar tape in order to avoid the ingress of dust and water.
The room is freed from furniture and unnecessary things. If something cannot be taken out (wardrobes, walls), they are simply pushed away from the wall, wrapped in plastic wrap and secured with tape.

Make sure that the wallpaper has been glued to the plaster applied to the walls. Otherwise, it will be almost impossible to remove them - they will begin to peel off along with the top layer of drywall, thereby spoiling its surface.

Instructions for removing different types of wallpaper

1. How to remove paper ones?

A universal method is impregnation with water, and to speed up the process, it is advisable to use a household steamer. If the wallpaper was glued on drywall without putty, it is recommended to remove it in the following order:

Each wall is divided into small sections.
One piece is carefully moistened with warm water using a roller.
Wait 20 minutes or use a steamer.
Carefully remove with a spatula.
This is how each section of the wall is treated.

Excessive wetting with water and the use of improvised tools and devices can spoil and even destroy the outer layer of the wall. And then it will not do without additional putty... It is permissible to use special liquids, they are prepared according to the instructions on the package. The main purpose is to deeply penetrate the paper structure, soak and prepare for quick removal.

If the layers to be removed are not completely separated, they must be moistened again. Do not wet the entire wall at once, as the gypsum board will get wet along with the glue and canvases. This leads to disastrous results - replacing all sheets in the room.

2. How to remove vinyl wallpaper?

They are covered with a thin PVC film. There are several ways to delete:

With a knife, cut the top layer evenly into strips about 10 cm wide. From the bottom, lift this part with the corner of a spatula and carefully remove a sheet of vinyl wallpaper, but the base of paper will remain. It is removed with warm water and gentle scraping.
The moisture-resistant protective layer must be destroyed with a needle roller or "tiger". This tool has self-sharpening discs located on its surface. During interaction with wallpaper, their top layer is perforated, and the gypsum board underneath is not damaged. Watch out for pushing against the wall cutting tool was moderately strong, since gypsum plasterboard easily damaged.
Similar to the previous one, but the difference is that a drill with a specific attachment is used.
The presence of a thin paper base suggests that you need to work especially carefully. To facilitate removal, you can spray the surface from a hot hair dryer or iron it with a warm iron. They start to shoot from the bottom of the floor and preferably from the corners of the room.

3. Liquid.

In the departments of hardware stores and supermarkets, special washes are sold that are added to the water. If this is not possible, use a solution: the primer is diluted in warm water and applied to the wallpaper. After a few minutes, using a spatula, they can be easily dismantled.

4. Non-woven.

The layering of this type allows you to easily remove them from the wall. The top layer is easily removed, and a very thin paper base remains on the drywall sheet under it.

5. Washable.

First, the protective layer is removed, and then their base. If the canvases are glued without putty, they begin to dismantle them from below and from the corner, gently prying them with a spatula. The upper main part will go away, and the paper will remain on the gypsum board. It can be easily removed with a soft brush and warm water.

After the drywall is given time to dry. A fan heater comes in handy for this purpose. If, after drying, there are some fragments left on the wall, they are cleaned sandpaper zero. After that, a primer or finishing putty is applied.

In order for the new wallpaper to lay on the walls evenly and beautifully, it is recommended to clean the wall by removing the old layer. And if with brick or concrete wall old coatings of this type are removed quite easily, then some problems often arise with drywall. Although this is a durable and reliable material, it does not withstand mechanical damage and negatively perceives moisture. Therefore, during the repair, the question may arise of how to remove the wallpaper from the drywall without damaging it. There are a few useful tips on this topic, which we will share with you in this article.

Why is it necessary to remove the old wallpaper layer?

Anyone who has ever worked with drywall knows that it is an even, pliable material, on which a new layer of wallpaper or paint will easily lay, even if you do not remove the old one. This is indeed the case, however this way can lead to some problems:

The new material can lie with defects - bubbles, bulges and irregularities appear. Even if the previous layer was glued perfectly, flaws are guaranteed.
The glue under the decorative coating contains a small amount of water. As a rule, it depends on the thickness of the glue, its quality and composition. For this reason, new wallpapers may one day simply fall off the wall.
On basements, kitchens and in places of high humidity, mold, fungus, various microorganisms that are harmful to health often appear under the wallpaper. Therefore, applying a new coat without removing the previous one can be unsafe.

Preparing for withdrawal

Before you remove the wallpaper from drywall, you need to prepare well. To do this, you need to acquire the following tools:

The process of removing these coatings is very different, depending on the material from which they are made. But in any case, the process of preparing the premises is identical:

Cover the floor to avoid damage and dirt. You can, for example, lay down old newspapers and cover the floor with plastic wrap.
Cover all sockets with masking tape - this will help you avoid water ingress, which can cause a short circuit.
Remove all unnecessary things from the room, and also take away the furniture. If this is not possible for some reason, then the furniture must be covered with a protective material - again, you can secure newspapers or film with tape.

Important! Before removing old wallpaper from drywall, it is imperative to ensure that it has been adhered to a layer of plaster applied to the walls. Otherwise, it will be almost impossible to remove the material, no matter what material they are.

How to remove vinyl wallpaper from drywall?

If the past decor is vinyl or non-woven coverings, then we can say that you are very lucky. These materials are removed in one single layer.

First you need to scratch the old layer very hard in order to break its integrity. To do this, you can use a roller with needles or the so-called construction "tiger". Ultimately, shallow grooves should form on the wall, which greatly facilitate the removal process.

Important! Make sure that the pressure of the cutting tool on the wall is strong, but not excessive, because drywall is quite easy to damage. Make sure to cut only the wallpaper, not the wall.

After the old coating is well scratched, you can begin to remove it. The easiest way to do this is to start from the ceiling. Place your hand on any cut piece and simply pull the wallpaper off the wall. Remove the rest of the decor with a spatula and a construction knife.

Removing paper wallpaper

Covering with paper wallpaper is the most common wall decoration option. Therefore, the question of how to remove wallpaper from drywall without damaging it is relevant for many repair lovers. First of all, you should understand that paper does not tolerate moisture well. This means that it is in this way that it will be easiest to delete the previous layer. By the way, wallpapers are also removed in the same way, because they are usually made of paper.

Here are some simple options:

Thoroughly dampen the wall with water using a rag or sponge. Wait about half an hour for the material to absorb the liquid. After that, they will begin to fall off the wall. A wide spatula can be used to speed up this process.
Using a steam generator will greatly speed up the removal of paper decor. In addition, this method allows you to evenly distribute moisture over the entire surface of the wall, as well as to affect the old coating using temperature. The deletion algorithm is similar to manual option- moisten the wall, wait for a certain time, remove the rest of the material with your hands or a spatula.

Important! When using water on drywall, be sure to make sure there is plaster underneath the wallpaper. Otherwise, you can ruin the plasterboard wall.

Removing liquid and washable wallpaper

When working with these types of wallpaper, it is important to know that they are excellent in repelling water. But if you correctly approach this issue, then there will be no problems with how to remove the old wallpaper from drywall in this case:

To get started, take a knife, roller with needles or a construction "tiger".
Scratch the wall just like you would with vinyl wallpaper. Be very careful not to spoil the surface of the wall.
Moisten damaged wallpaper with water using available tools - a sponge, rag or roller. Or with a steam generator.
Wait half an hour, and then proceed with the removal. Using a spatula in this case will significantly speed up the process.

Alternative ways

If none of the above methods helped, do not despair. There are several alternative methods that you might find useful:

If paper wallpaper adhere very tightly to the wall, and under them there is no layer of plaster, then you should not even try to peel them off. It is necessary to walk with a layer of primer over the old wallpaper - this will protect against mold and mildew, and also prepare the wall for gluing. After completely dry, just stick on a new layer. This method is only suitable for paper wallpapers.
In any hardware store, you can purchase a special solution for wallpaper. It is sometimes called a wash. As a rule, this tool is great for removing wallpaper from drywall. However, before applying, you need to make sure that the remover is right for your type of wallpaper.
An iron can be used as a steam generator. It will not only help moisturize the wall, but also thanks to high temperature will kill some types of bacteria. In addition, the high degree of steam makes the wallpaper fall off faster.

How to remove wallpaper from drywall for wall putty

To understand how to remove wallpaper from drywall, you need to understand the structure of the gypsum board, because, in fact, you will have to separate the glued paper. Experts advise resorting to such a procedure only in case of emergency, for example, when there is greasy stain or you decided to putty it. But if you suddenly want to update the wallpaper, then you better stick the new ones on top of the old ones, so as not to create unnecessary problems for yourself.

Wallpaper on drywall is easier to stick than to remove

Plasterboard and wallpaper

Knowledge of the structure of the gypsum board will help to understand the intricacies of the process of removing old wallpaper. The wallpaper strip most often has a paper base, so when gluing two surfaces, we get a thicker layer of cardboard. It is this structure that we will have to disconnect.

Drywall structure

In the photo, the process of forming a drywall sheet

So, the gypsum filler, called sludge in production, is closed on both sides with thick paper or cardboard like a sandwich and pressed in.
All drywall is divided into several categories: wall, ceiling, moisture resistant and fire resistant. Regardless of the various additives used for one type or another, the basic instructions for making sheets remain unchanged and paper will definitely be the top layer. Therefore, the price of old wallpaper or its type does not matter when dismantling.

Dismantling process

We remove wallpaper with the whole family

If you are deciding how to remove wallpaper from drywall, then the main problems usually arise when their surface does not allow water to pass through or they are glued to non-standard compounds, for example, PVA. After all, the dismantling of such a cladding takes place with the help of water and there is an urgent need for its penetration into the adhesive base.
Of course, if the wallpaper was glued to the putty drywall, then special difficulties with their removal does not occur, even if the surface is difficult for water to penetrate. From such a foundation, they can simply be scraped off with a short spatula. If, during dry or wet dismantling, damage to the putty surface occurs, do not worry, you can hide scratches, chips and even potholes with a liquid solution.

The photo above demonstrates how to remove wallpaper from a drywall wall if it was poorly glued.... But this happens extremely rarely and the paper, glued to a homogeneous structure, either does not come off at all, or pulls part of the base with it. Surely I had to deal with a situation when the removal of the coating from the gypsum board ended up falling not on the sludge (filler), but on the lower part of the light brown cardboard.
If you remove wallpaper from drywall in this way, the sheets will weaken and will not withstand the layer of putty. In such situations, under mechanical stress (impact, push), the putty surface will crack. As a result, the entire wall may become unusable and will require complete dismantling.

For dismantling, the wallpaper is soaked

Advice. Before removing the wallpaper from drywall, vinyl based, think about a way to retain moisture on their surface.
The need for repeated soaking is justified by the fact that vinyl is completely inert to moisture.
To prevent the water from flowing down from the vertical plane, you need to add a little glue to it, with which you previously glued the wallpaper. In this case, the liquid will not drain, and you can remove the wallpaper from the drywall without much difficulty.

Removing wallpaper with a steamer

Vinyl is more or less susceptible to water penetration, but even professionals are thinking about how to strip wallpaper from drywall, if it is washable. For this, one of three rather effective methods is usually used, which allow moisture to penetrate to the adhesive base and dissolve it.
The safest of all three methods is using an electric steamer, but such a tool is quite expensive and rare. Nevertheless, removing wallpaper from drywall with the help of such a device is very convenient and the whole procedure takes place quite quickly.
Before tearing the wallpaper off the drywall, try to separate it by hooking the top layer with a spatula. After that, the remaining layer is removed using ordinary soaking, without making any special efforts. (See also Wallpaper Wall Design: Features.)

Cuts are made to retain water on the washable wallpaper

But not all washable wallpaper can be layered, because there are also quite thin specimens. In this case, you can apply the third, last option - a notch. Horizontal cuts are made along the entire plane on the wall with a painting knife, then moisture, getting into them, lingers and dissolves the glue base.

It is better to putty drywall under the wallpaper

Even at the stage of wallpapering, be prudent and be sure to pre-putty the plasterboard wall using a thin layer of satengypsum applied directly to the previously primed surface.
If you nevertheless decide not to putty the plasterboard, use non-woven wallpaper, which delaminates, and the base itself is removed in the usual way. Several interesting solutions we have prepared for you in the video in this article. But be that as it may, each situation is individual and requires the same individual solution.

Advice. If you still need a steamer, but there is nowhere to take it, you can use an electric iron with a similar function.
The process will be quite long, but you will carry out the dismantling with high quality.

Conclusion

We looked at how to remove wallpaper from drywall on our own, using the usual tools at hand. But there is one more method - this is a special ATLAS ALPAN product, which can be purchased at hardware stores. The liquid has excellent penetrating properties and quickly dissolves the adhesive base.

We hope our article was useful to you. In order to more accurately understand the technological and practical issue, our website contains detailed photo and video instructions, in which you will find useful information on this issue.

Ways to remove wallpaper from drywall

This variation is very popular due to its affordability and ease of installation. To remove such a finish, the following work is carried out: Sometimes it is impossible to accurately determine the most suitable method, in this case several options or a combination are used taking into account the best result. This problem arises when the coating of the gypsum boards and the glued canvases are securely adhered. In this case, it is possible to remove the decorative layer only with a serious violation of the structure.

Such a defect, especially with large-scale damage, will significantly reduce the reliability of the walls. Specialized chemicals are considered to be very effective remedy removing wallpaper, but such liquids usually have a strong odor and can be toxic

The painted coating is gently pry off. First, you need to remove areas that are easy to move away.
Remaining seats are being processed hot water or ferry.
The base can have a strong adhesion to the gypsum board, then it will not be possible to peel off the layer, so it is sanded and the putty surface is recreated.

As for the workflow, you can do it yourself, but save gloves and goggles for work. Hot steam is still used and there is still a risk of scalding. Do not use toothed rollers, knives, or other devices to cut through the wallpaper.

You can damage not only the coating, but also the drywall base and ruin all the walls. In our case, we need a wallpaper tiger that carefully breaks through the top layer.

How to remove old wallpaper from drywall effortlessly

Soaking with subsequent reuse;
Exposure to a building hairdryer;
Sawing with a grinder;
Manual removal with a scraper and trowel after applying an acrylic primer solution.

Front before starting work, consider the surface of the wall: if a drywall sheet is covered with putty, then specialized chemical solutions should be used for work, under the action of which the adhesive layer is destroyed. After wetting the surface of the walls, you should wait about half an hour - then the old wallpaper will literally just “slide to the floor.

If plaster was applied to drywall before laying the tiles, you can try to remove one tile at a time, picking them up with a sharp chisel;
Saw out on the tiles with a grinder, if it does not work without a foundation, then together with drywall.

So, above were considered ways of how to properly remove old wallpaper from the wall. But what if another surface is pasted over, for example, drywall? The number of wetting procedures will be determined by the density of the wallpaper material. The higher it is, the longer the wetting process will take.

Hence - and expectations. It is better to soak wallpaper in rows. Each canvas is moistened from the top to the bottom. What is not less important. Before removing the wallpaper from drywall, you need to stock up on the following arsenal of tools and materials: a wallpaper tiger, a knife and a construction spatula, a roller or a sponge, dishes with warm water.

At the same time, the use of strong adhesives makes the process of their removal extremely painful. In such conditions, it is very important not to damage the main paper layer covering the gypsum. Before gluing the new wallpaper to the drywall, the old covering must be completely removed. Can water be used to eliminate it?

The GCR paper base is very difficult to wet through. Moderate exposure to moisture is absolutely harmless to the material. If the services of professionals are not affordable, and you do not have enough skills to plaster the surface yourself, it is better to stick non-woven wallpaper. Subsequently, they can be removed without problems and a thin substrate can be used as a basis for new ones. You can safely glue the new wallpaper on the old non-woven layer, if it is securely adhered to the drywall sheets and was not damaged during dismantling.
But when the integrity of the non-woven fabric is broken, it must be removed in the same way as the vinyl wallpaper. It can be difficult to remove wallpaper from drywall for the reason that often PVA building glue is added to it to strengthen the wallpaper composition, or the canvases are completely glued to PVA.

So that old wallpaper can be easily removed from plasterboard walls

Decorative coating on any substrate can be easily removed using special fluids that can be purchased at construction markets and in household goods departments. Removing glass wallpaper for painting will require special effort. In some cases, it is easier to cover the decorative layer with a primer and stick new wallpaper on it, since it is almost impossible to remove such a specific composition without damaging the drywall.

The beginning of removing paper wallpaper is to wet the entire canvas with water. This can be done with a rag or sponge. After wetting the wallpaper and waiting for half an hour, you will see that in some corners the paper itself will begin to lag. You just have to tear it off to the end with a spatula.

If you need to speed up the process, then experts recommend using a steam generator. Since it distributes moisture evenly, the wallpaper will be removed the same way. The process is the same as with water, after moistening the surface, you should wait and start removing. Sometimes the wallpaper can be removed by simply prying it up with a spatula and pulling it away from the wall.

But such situations do not happen often, especially if it comes about drywall. This is the easiest option. It is obvious that the paper is not friendly with high humidity.

Therefore, you need to use everything that can soak the wallpaper sufficiently so that it swells and easily peels off the surface. A variety of tools can be used to soak.

Drywall is a rather capricious material that does not tolerate well high humidity and the action of gravity. Therefore, the question of how to remove old wallpaper from drywall without damaging the surface needs separate consideration.

Types and structure of gypsum plasterboard (hl)

Before removing the wallpaper from the drywall, it would not hurt to remember how the drywall works.

This construction material, depending on the purpose of its use, there are several types:

ceiling;
wall;
refractory;
moisture resistant.

However, all hl, differing from each other only in the additions in the composition, have the same structure. The sheet consists of a compressed gypsum filler (sludge), which, like a sandwich, is covered on both sides with a protective layer of cardboard. It is the cardboard that serves as the basis for wallpapering, and it is from it that the old wall covering will have to be ripped off.

What you need to think about in advance

You should think about replacing the finish even at the stage of pasting new plasterboard walls with the first wallpaper. Prudent owners know that observing the following three rules before starting finishing work will greatly facilitate the replacement of the coating in the future:

Prime and then putty the plasterboard wall with a special gypsum plaster, preferably over its entire area, and not only in the places of inter-sheet seams. This work is quite painstaking and time-consuming, but it will allow you to save energy and money during the next repair. In this case, neither water nor a spatula will be afraid of drywall - damaged areas (potholes, destruction, cracks) can easily be masked with a liquid solution. It will not be difficult to tear off even waterproof material from the putty drywall.
Use only wallpaper glue. Non-standard types of adhesives, such as PVA, can firmly attach finishing material, and it will be possible to tear off the wallpaper only with pieces of drywall and with putty falling out of the seams.
If the decision is still made to do without putting putty on the entire surface of the walls, then it is best to choose non-woven wallpaper as the first coating on drywall. When dismantled, they easily peel off, and the non-woven base remaining on the wall will not interfere with the gluing of the new decorative material in any way.

Features of removing wallpaper from a drywall made of various materials

The technologies for removing old coatings differ slightly depending on the material from which they were made. The type and structure of the stripped panels are important for the choice of the method of their dismantling. Consider a solution to how to remove wallpaper from drywall, for each of their types.

Paper

If thin paper wallpapers were glued to the plasterboard wall at one time, then you need to check how firmly they hold. If the quality of their gluing does not cause any complaints, there are no bubbles or peeled areas anywhere, then there is no need to tear off the old paper covering. Clean it from dust, prime it and boldly use it as a base for a new one.

If the paper wallpaper definitely needs to be peeled off, then the easiest way to remove it is to soak it:

Using a large sponge and warm water, evenly moisten the wallpaper surface, moving from top to bottom - this way you will be able to pick up excess water and prevent drywall from drying out.
After 10 minutes, pry the paper strip from the bottom or top with a spatula, and, pulling it towards you, try to separate it from the wall. In most cases, it turns out in this way to tear off the wallpaper without extra effort and special difficulties.
If there are any pieces on the wall, moisten them again and repeat the operation. Sometimes paper wallpapers fall behind very hard, and you have to spend a lot of time and effort removing them in small pieces.

Tip: do not wet all the walls in the room at once. It is more practical to wet and remove the wallpaper in stages, otherwise the wallpaper moistened in advance may dry out, and all the work will have to be redone.

Non-woven

To glue the original plasterboard surface with a decor on a non-woven base was a smart decision. And if now you have to face the need to remove wallpaper from this material - consider yourself lucky.

Before removing non-woven wallpaper, moisten the entire area with water using a flower sprayer, wide brush or roller. After a few minutes, the top layer will peel off from the bottom layer and can be easily removed. Only a film will remain on the plasterboard wall, which will serve as an excellent basis for gluing a new coating.

Vinyl

They do not absorb water well, so you need to remove such wallpaper from drywall after repeated wetting. The difficulty with wetting vinyl is that water from the walls drains very quickly onto the floor. Therefore, the dismantling of this material has some nuances.

So, how to remove vinyl wallpaper from drywall:

Prepare a solution in advance to soak them. To do this, add a little wallpaper glue to the water (1/3 - 1/4 of the normal amount for preparing glue in a given volume of water), stir and let stand for about half an hour.
Wet the wall with the resulting solution and wait a few minutes. The canvases should be completely wet, so it may be necessary to apply the liquid two to three times.
Then use a sharp knife to cut a cut at the top of the strip under the skirting board.
Insert a metal spatula into the cut and separate the wallpaper from the drywall. Damp vinyl strips are easily removed from the plasterboard base, falling to the floor in heavy, solid layers.
If there are pieces on the wall, then wet these places and remove them with a spatula.

Important: you need to completely wet the entire area of the wallpaper from bottom to top. Do not leave dry "islands"!

Washable

How to remove wallpaper from drywall if they have a particularly moisture-resistant outer layer? Your task is to provide water access to the lowest, paper layer of the wallpaper. You will have to damage the washable cover a little by making a lot of holes or cuts in the wallpaper.

To do this, you can use the following tools:

wallpaper knife;
razor;
coarse sandpaper;
wallpaper tiger - a device with rotating cogwheels that punches numerous holes in the wallpaper.

Combination mechanical processing with soaking gives excellent results. Wet, washable wallpaper will peel off the wall in the same way as vinyl wallpaper.

Be careful and careful when working with a knife, razor or perforation roller. You can not make excessive efforts, because you can ruin not only the wallpaper, but also the drywall sheet under them. It is best to use a wallpaper tiger - it will carefully and accurately punch holes only in their outer layer.

Steamer

A professional steamer for separating the coating from the base is similar in design to a vacuum cleaner. Under the influence of hot steam, the dried glue will dissolve, and it will be very easy to tear the wallpaper from the drywall.

Some home craftsmen use an ordinary iron with a steaming function in this capacity. With the help of a steamer, you can easily separate any, even the thickest and thickest wallpaper from the wall.
