Is it possible to glue new wallpaper onto an old canvas? How to hang wallpaper alone. Practical advice Is it possible to glue wallpaper onto washable wallpaper?

The answer to the question whether it is possible to glue new wallpaper onto a different coating largely depends on what material the old wallpaper is made of. If they are made of paper and glued securely and evenly, the answer will be in the affirmative.

Here again we need to make a reservation that this is possible if there are no flaws, irregularities or tears in the old wallpaper. Be sure to check all the joints of the previous covering for any separation from the wall. If there is even the slightest chance that at the junction of the old wallpaper the new ones may lag behind the wall, it is necessary to treat these areas with joint glue.

Be careful when applying wallpaper paste. It should not be applied in large quantities to a new coating. Otherwise, the previous wallpaper and old glue will soften, and the new coating may come away from the wall along with the old one.

In addition, it is worth considering the possibility of coloring properties of the old paper coating. If you put thin wallpaper on it, the paint may bleed through it and thereby ruin all your work. Also, as a result of gluing thin wallpaper (especially plain ones) over old structural and variegated ones, the fact that there is an old coating underneath may become apparent.

Vinyl wallpapers have the property of repelling water, and therefore wallpaper adhesives. Therefore, gluing a new coating onto vinyl is almost impossible. It is also worth considering that most vinyl wallpaper has a relief structure. If the new coating is thin and transparent, it will be quite noticeable.

As for non-woven wallpaper, it has a vinyl surface, and therefore gluing a new coating on it is also not recommended. However, non-woven wallpaper can be removed from the walls quite easily. More precisely, their vinyl surface is torn off, and non-woven material remains on the wall. In this case, the new coating can be glued to non-woven fabric.

What do you get when you put wallpaper on wallpaper?

To decide whether it is worth gluing wallpaper onto wallpaper, it is advisable to first weigh all the pros and cons of this decision.
What benefits will you get:
- save a lot of time and effort on stripping off the old coating;
- no need to level the walls.

What are the disadvantages of this method of wallpapering:
- the walls will not be level;
- the new coating may not adhere well;
- bubbles may appear on the new coating after pasting;
- the risk of developing various bacteria and molds harmful to human health increases;
- the service life of the new wallpaper will decrease, they will begin to peel off along with the old ones.

How to minimize the risk of negative consequences

To minimize risk negative consequences, old wallpaper must meet the following requirements:
- be smooth in texture and not have a three-dimensional pattern;
- completely paper in composition;
- securely attached to the surface;
- refer to thin wallpaper;
- a light pattern or design does not pretend to be visible through the new wallpaper.

In addition, you should be more careful when choosing the adhesive composition. To increase the strength of the new coating, it is desirable that the glue penetrates through the old wallpaper and is able to hold it on the wall surface.

Secrets of gluing new wallpaper over old ones

First you need to check the reliability of fastening the old coating to the wall surface. When gluing new wallpaper, you need to start with one strip, allowing it to dry until the next day. If the first one is well fixed and does not pull off the old coating, continue gluing new strips one after another.

It is safer to clean the wall surface from the old coating, prime and degrease it, and only then start gluing new ones. Preparing walls requires time and money, but the result will be more durable.

If after a while a few bubbles appear on the wallpaper, you can try to smooth them out with a hot iron. During work related to wallpapering walls, exclude active air movement. To do this, keep the windows closed, turn off the air conditioner or fan, and move around the room at medium speed.

You can ventilate the room only when the new wallpaper on the walls is completely dry, i.e. in about 3-5 days.

There are situations when dismantling wallpaper can take a very long time. The reasons can be completely different: from too strong wallpaper glue to gross mistakes during wallpapering. Naturally, then the need arises to apply a new layer of wallpaper on top of the previous ones. We can immediately say that this is possible, some people practice it: but you need to be prepared for many inconveniences and problems that a person may experience during this process.

The good thing about gluing wallpaper on old flooring is that:

• There is no need to spend money and effort on processing the wall and leveling it.
• If the old wallpaper was glued to drywall without prior priming, then in order to remove the old wallpaper, you will have to tear it off along with the sheet of drywall itself. Gluing new wallpaper onto old ones will be relevant in this situation and will save a lot of money.

If possible, you should choose new wallpaper that is similar to the old one. That is, if the old wallpaper was cream-colored, then it is advisable to buy wallpaper of the same shade: one of the disadvantages of gluing new wallpaper instead of the old one is that there is a possibility that the old wallpaper will be visible under the new one.

It is also worth considering that such wallpaper is short-lived and can simply fall off at any time: wallpaper requires an ideal surface. Unfortunately, gluing new wallpaper is only possible on paper wallpaper.

Unfortunately, this cannot be done with non-woven, vinyl or photo wallpapers for several reasons:

1. The surface of vinyl wallpaper is textured: naturally, such wallpaper is not suitable, since a flat surface is needed.
2. In addition to the fact that vinyl has water-repellent properties, it also has the ability to repel adhesive solutions that are necessary for gluing wallpaper.

This also applies to non-woven wallpaper, since the material of their outer layer is vinyl.

If the wallpaper is coming away from the wall, it would be better to remove it.

How to remove old wallpaper: the quick way (video)

How does the process of gluing new wallpaper onto old ones take place?

The first thing to do is to prime the wall on which we will apply wallpaper. The material for the primer is glue, which we will use later when we hang the wallpaper. The next stage is cutting the wallpaper: when cutting the sheets, you should add about five centimeters to the height of the wall for reserve. The following algorithm of actions is no different from gluing regular wallpaper. That is, you need to start gluing from any corner in the room. During the gluing process, you need to level the wallpaper with a spatula. Immediately after gluing the first sheet, you can proceed to the second: it needs to be glued in exactly the same way as the previous one.

There is no need to overdo it with applying glue: an excess of adhesive on new wallpaper can soak away the old glue.

You should pay attention to the pattern on the wallpaper: in order for it to look seamless, you need to apply the sheets of wallpaper as carefully as possible. Please note that before the actual process of wallpapering, you need to apply glue to all the joints of the previous wallpaper.

How to properly glue wallpaper (video)

Is it possible to glue wallpaper over old paint without losing the quality of the result?

Before gluing wallpaper on old paint, you should determine what type of paint you are using: some types of paint can be used for wallpaper, but some cannot. For example, on water-based paint You can’t stick wallpaper properly, because the wallpaper layer can fall off almost immediately. If your walls are covered with enamel, then you are very lucky, because you can paste new wallpaper on them without any problems. But before gluing wallpaper onto the enamel, you need to check how strongly the paint adheres to the wall surface: you need to take tape, stick it to the painted surface of the wall, and quickly tear it off: if some of the paint is on the tape, it means that the paint does not adhere well.

If there is a small amount of paint on the tape or there is none at all, then you can start working:

• If there are areas on the wall where the paint is coming off or peeling, then you should get rid of it.
• The wall needs to be treated sandpaper over the entire surface.
• Be sure to get rid of dust on the wall: this can be done with a rag.
• The final stage is treating the wall surface with an impregnation intended for walls.

If you have the opportunity, it is still advisable to remove all the paint from the wall: although you will spend some time dismantling the paint, the result will be much better than directly sticking wallpaper onto the paint.

This method of gluing should only be used in exceptional situations.

The risk must always be justified: that is, if a person is simply too lazy to prepare the surface for wallpapering, then if he wants a decent result, he will still have to work hard; nothing comes easy. A lot of people have already had bad experiences when they simply did not want to dismantle the old wallpaper, but simply pasted new wallpaper on it: in most cases, such wallpaper came off very quickly. Funds for wallpaper that didn’t last long were wasted, as was energy: that is, it was all in vain. You should take such a risk only in extreme situations: if you have no choice, then you can still use this method of wallpapering. The most important thing is to follow all the recommendations and work hard!

Is it possible to glue wallpaper onto old wallpaper (video)

A universal finishing material for walls - wallpaper, enjoys well-deserved popularity in our country, and this is no wonder, since it appearance It’s pleasing to the eye, and it’s easy to stick it yourself.

How to make high-quality gluing is a difficult question

The modern choice of wallpaper will not leave anyone indifferent; any skeptic will choose the material and color to suit his taste. If you want to create an excellent design that can accommodate several colors and types of wallpaper, feel free to contact the professionals, they will help you with this.

Wallpaper for wallpaper - a redecoration idea

When undertaking a renovation, we all subconsciously prepare for constant dirt and dust in the workroom and adjacent areas, so the timing of the work worries us most of all. To avoid general contamination, to speed up work and save money, the option of gluing wallpaper over the old ones is always on the surface.

In this case, you can forget about large scale pollution, and the surface under the wallpaper may not be primed at all, but is it possible to do this? The fundamental answer to the question about wallpapering is “no.”

It is best to approach the issue of wallpapering more seriously

If you seek advice from professional craftsmen finishing works, then you will receive such an unambiguous and specific answer. They will also add that in order to avoid problems with repairs in the future and to give the room an ideal look, you need to:

• remove old wallpaper from the wall,
• level the surface as much as possible, get rid of all its imperfections and defects,
• prime it special composition or glue,
• Paste new wallpaper onto the finished wall surface.

In many cases, removing wallpaper from a wall is quite simple and does not require any special skills. To remove wallpaper we need water, soap or special remedy for removing wallpaper, which is diluted in a certain proportion.

We carefully wet the wallpaper on the wall, let it sit, absorb moisture, and try to carefully remove it in one piece. Knives and façade spatulas are helpful for removing wallpaper.

No one is trained to work with a spatula, everything happens intuitively

If it is not possible to tear off the entire canvas, we make notches on the wallpaper, which will facilitate the penetration of moisture inside, and remove it in small pieces.

If we need to get rid of washable, moisture-resistant wallpaper, then cutting through the wallpaper is simply necessary, because otherwise moisture will not get inside it.

Modern wallpaper, properly glued to the wall, will not pose any problems in removing it. This process will take at most half an hour. Don't forget to cover the floor and furniture protective film, which will protect them from dirt and crumbling plaster.

If the wallpaper glued to the wall is vinyl, then you have to remove it from the wall twice, first remove the vinyl covering, and then the paper backing, but the non-woven backing is tightly attached to the vinyl, and comes off along with the wallpaper.

The walls of the room are ready for wallpapering

The master’s answer reflects a high-quality approach to repairs, but if we make a mess when doing cosmetic work, then we do not do all the work, reducing time and reducing the consumption of effort.

When is it permissible to glue wallpaper over old ones?

To paste new wallpaper onto old ones, we still need to make some manipulations with work surface, for example, prime it and degrease it. If you don't take care of this in advance, even redecorating it may not succeed.

In some cases, dismantling the wallpaper will be difficult

However, before priming, make sure that the old wallpaper can withstand the new wallpaper; it must meet the minimum requirements.

1. Only paper wallpaper can be glued on top; other textures are not capable of holding a large wallpaper sheet.
2. Old wallpaper should be glued very well, and should not lag behind the wall anywhere. Even small voids under the wallpaper will subsequently lead to large bubbles on the new canvases. In addition, two layers of wallpaper simply cannot stay on the wall and will come off.
3. or with a three-dimensional pattern are not able to hold the wallpaper on top of themselves, since the contact area is minimal. This point basically follows from the first one; make sure that you are gluing on a simple, texture-free surface.
4. It is advisable that the old wallpaper be made of plain paper, thin and smooth, because... Duplex is already a stretch.

In addition, when gluing new wallpaper onto old ones, a large number of shortcomings emerge that can significantly spoil your mood and the appearance of the walls.

The main disadvantages of wallpapering wallpaper

Whatever color and pattern you choose for new wallpaper, there is always a possibility that it will shine through, and patterns from previous paintings will creep through.

It is worth carefully choosing new wallpaper if you have pasted such canvases

The appearance of such a wall will not be the best. This effect occurs if the wallpaper pasted on top has a fine structure and light colors.

The worst option would be to paint new canvases the same color as the old ones; this often happens when the old wallpaper gets too wet from modern extra-strong adhesives and the quality of the paint on its surface is poor.

Pasting will definitely be difficult; old canvases will get wet and form air bubbles, both against the wall and between the layers of wallpaper. There are options for detaching the entire sodden old canvas from the wall, and this will also have to be dealt with.

Another unfavorable effect of gluing may appear after some time, when the wallpaper again begins to move away from the wall and from the old wallpaper. They move away from the wall due to their weight, which the old glue is simply not ready to hold. New wallpapers move away from the old ones if the structure of the old one is torn wallpaper. The problem can be fixed, but again it takes time and effort.

Wallpaper coming off the wall is one of the most common problems associated with improper gluing.

In addition, soaked old canvases create an excellent atmosphere for the growth of fungus and mold near the wall, which over time will appear on the new wallpaper.

And the last thing is a reduction in the service life of such wallpaper, which is obviously glued incorrectly. Expecting them to hang on the wall for at least ten years is, to say the least, stupid.

Pasting wallpaper over old ones

If all the warnings described above do not bother you, and you still decide to glue new wallpaper over the old ones, then initially you should carefully inspect the wallpaper that has already been glued.

We inspect them for defects, the quality of joints, connections to the wall, and make sure that the wallpaper on the wall is really paper. If there are places where the wallpaper is coming away from the wall, tear it off, nothing bad will happen.

If you are not sure, try slightly wet the wallpaper; if it doesn't stick well, it will immediately come off the wall.

The next step is to select the quality, color and design of the new wallpaper. In terms of quality, we look at the thickness, try to avoid thin, translucent canvases, and settle on thick vinyl.

Thick vinyl wallpaper suits us perfectly

In principle, any design will suit us, but the color is preferably dark, or as close as possible to dark shades. If the old wallpaper has a bright pattern, it will be very difficult to disguise it with a new layer.

When applying glue you should be careful and careful, the main thing is not to overdo it. You should not allow old and new wallpaper to get too wet, since moisture increases its severity many times over, and the old wallpaper glue may no longer cope.

The wallpaper has been chosen, it's time to start gluing it. IN last time We inspect the surface covered with old wallpaper, if everything is in order, mix the glue, cut new sheets.

The first canvas will dot all the i's. We glue it in the corner, straighten it, expel the air from under it and wait for it to dry. As soon as the canvas has more or less dried, we are ready to draw conclusions about whether it is able to adhere to old wallpaper in principle, whether it adheres well to the wall and how it looks.

Pasting wallpaper onto wallpaper is definitely not the easiest task.

If the result suits us, we continue the process of gluing the old wallpaper on top of the new.

Watch carefully for air bubbles between the layers of wallpaper, try to remove them all. If, as it dries, new, small bubbles form, do not panic, there is nothing to worry about, they will eventually smooth out.

The general rules for wallpapering should also be followed, especially those related to drafts. It is necessary to minimize air flow in the room, turn off heaters, fans and air conditioners. Later we will ventilate the room, but for now we need to wait 1-2 days until the wallpaper dries completely and the glue sets.

Pasting on vinyl and non-woven wallpaper

As we know, all of them have water-repellent properties, so the glue simply won’t stick to them, which means we won’t be able to stick new wallpaper on them.

The picture is the same with non-woven fabric; its functionality does not allow wallpaper to be glued to it; moreover, such wallpaper has a significant relief, which means that the contact area will be minimal.

Gluing non-woven fabrics meter wallpaper on the same ones, will seriously increase the weight of the wallpaper, so it is highly not recommended

However, do not be upset, non-woven and vinyl wallpapers are very dense and wear-resistant, so in most cases they can be easily removed from the wall.

If the gluing was carried out according to all the canons of construction skills using good wallpaper glue, then the process of dismantling the wallpaper will not take much time and will not take much effort.

Tool for removing and hanging wallpaper

The work should be carried out professionally; a good construction tool will help us with this:

• a container for mixing water with glue, a bucket or basin will do just fine,
• a roller and a tray for glue, using which we will coat the canvas, it is inconvenient to do this from a bucket, foam rubber is perfect for covering the roller,
• scissors and a knife will help us get rid of excess wallpaper, cut through old canvases and trim corners,
• made from soft plastic, it will help us smooth out the wallpaper and get rid of the air under it,
• rags and sponges, glue will constantly appear, it will need to be removed, preferably with dry material,
• stepladder or stool for working at the top of the wall,
• We don’t need a table if it is possible to roll out the roll on the floor.

A high-quality tool will help you get the job done quickly and well.

Take care of your tools in advance so that you don’t create unnecessary drafts later by searching for tools throughout the apartment.

Whether or not to glue new wallpaper over old ones is, of course, up to you to decide, but we recommend spending a little more effort and time, but getting a better and more durable result. In the long run, you will most likely be unhappy with the quality of the finishing material glued one on top of the other.

Wallpapering is the most common option when renovating premises. Ease of installation and availability of materials allow you to do the work yourself. In this article we will tell you in detail how to glue wallpaper with your own hands, starting with the choice of materials and glue, ending with the tricks and advice of experienced experts.

Preparing the walls

The preparatory stage should begin with clearing the walls of all unnecessary objects. Sockets and switches, baseboards, as well as door panels must be dismantled to simplify the work.

Let's do everything ourselves!

We carefully prepared this article before publication, and therefore we will tell you about all the nuances of gluing walls yourself: how to choose glue, how to apply it, how to glue it, etc.

It is recommended to de-energize the room to prevent damage electric shock in production wet work. If this is not possible, it is necessary to carefully insulate the wires of switches and sockets and hide them in socket boxes.

Old wallpaper

Then you should start preparing the walls. If the walls are decorated with old wallpaper, they will have to be torn off. First they are removed by hand, and if you're lucky, the strips will come off entirely, but usually they come off poorly, in separate pieces. It is recommended to moisten the remaining fragments on the walls warm water and peel off with a spatula.

Difficulties may arise with vinyl samples with a moisture-resistant coating on the front side. It must be removed so that water can penetrate to the base and soak the glue. This will take a lot of time, but then the material will become more pliable and without special labor clean off with a spatula.

Paint Cleaning

If the walls are painted or whitewashed, the cleaning job becomes more difficult. The whitewash should be moistened generously with water and gradually removed with a spatula. Oil paint is more difficult and takes longer to remove, but there are ways to speed up the process. Firstly, you can use special chemical compounds To remove paint, secondly, use construction power tools.

The chemical method of removing paint will not be cheap and will require the use of personal protection, due to harmful fumes. As auxiliary tools To remove paint, a grinder or a hammer drill with special attachments in the form of metal brushes can be used. In this case, a respirator and safety glasses are also necessary due to the abundance of dust.

Alignment

When the room is cleared old decoration start leveling the base. The amount of work at this stage depends on the condition of the walls. Wall with Not big amount chips and minor defects will require only local alignment. Minor defects should be corrected with finishing putty, having previously treated the wall with a primer for better contact.

Pronounced wall irregularities will require more attention. You will need to putty in two layers - starting putty to correct major defects, finishing for final alignment. At the end, the walls are sanded with an abrasive mesh and cleaned of a layer of dust.

Types of wallpaper

Now on the finishing materials market there are many wallpaper options that have certain performance characteristics, advantages and disadvantages. Let's highlight the main types:

• Paper wallpaper. The most common type, characterized by low cost and ease of pasting. Paper wallpaper is environmentally friendly and great for bedrooms and children's rooms. On the other hand, they cannot be washed and do not retain their original appearance for long;
• Non-woven wallpaper is made from paper with the addition of non-woven fibers. They are durable, wear-resistant and not afraid of water. Gluing non-woven wallpaper is simple - the glue is applied directly to the walls. This finishing material is able to hide minor unevenness in the walls, which simplifies the process of leveling the base;
• Vinyl wallpaper consists of paper or non-woven backing covered with a vinyl coating. They are easy to clean and do not lose their brightness for a long time. Before gluing vinyl wallpaper on a non-woven backing, it is worth considering that they “do not breathe”, and it is not recommended to use them in children’s rooms and bedrooms;

• Acrylic finishing material is paper coated with an acrylic composition. Unlike vinyl wallpapers, they have a thin outer layer and are not as durable, but they allow air to pass through better;
• Natural. This type of wallpaper is environmentally friendly, exclusive and has a high price. They contain natural cork, straw, reed, etc. Application to walls requires some skill;
• Fiberglass material is ideal for office premises. It is durable and strong, is not afraid of water and does not burn. After application, it is painted with paints on water based, and this can be done dozens of times;
• Textile samples consist of natural fabric material, applied to a paper base. They look chic and expensive, and cost accordingly. They are sensitive to moisture and mechanical stress, and also absorb odors well;

• Metallized wallpaper has an outer layer of aluminum foil and is not afraid of external influences and easy to clean. Ideal for modern interiors;
• Liquid wallpaper is the most unusual type of all listed. They are based on cellulose, supplemented with decorative dyes, fibers, and glitter. The walls may not be leveled before applying such a coating. Glue them in wet areas not recommended due to hygroscopicity;
• Photo wallpapers are self-adhesive film, on which a certain design is applied. You can depict everything on the wallpaper, from ornaments to photographs, which allows you to make the room unique.

As a rule, wallpaper for a room is selected based on taste preferences, but in order for it to last longer, it is also necessary to take into account its characteristics.

Wallpaper glue

Selecting glue causes difficulties for many who have started repairs with their own hands. In fact, the variety of options presented should not scare anyone, because in order to make right choice It is enough to focus on the type of wallpaper used. There are several types of wallpaper glue, differing in composition:

• methylcellulose glue;
• CMC glue, based on carboxymethylcellulose compounds;
• starch based glue.

The choice of glue is made based on the following features:

• type of wallpaper;
• room microclimate;
• wall material.

First of all, you should decide on the type of wallpaper. Manufacturers of adhesives offer a wide range of products on the market from which to choose necessary option doesn't seem to be challenging task. Depending on the type of compatibility with wallpaper, the glue can be:

• for light wallpaper (paper);
• heavy wallpaper (fiberglass, textile);
• non-woven wallpaper;
• vinyl samples;
• universal, suitable for all types.

How to choose the right glue taking into account the microclimate of the room? Materials for wet rooms must be resistant to moisture and retain their properties under all conditions. In addition, damp rooms contribute to the spread of fungus and mold. The adhesive composition must contain antiseptic substances to prevent their appearance.

How to glue wallpaper with your own hands

Decorating walls with wallpaper is a procedure that you can easily do with your own hands, but it is important to adhere to certain rules so that the result is of high quality and the process itself does not take a lot of time and effort.

Final preparations

Before gluing wallpaper you need to go through the last preparatory stage– priming the walls. Priming allows you to achieve better adhesion between the base and finishing material. To perform the work, you can choose acrylic primer or use glue. Manufacturers adhesive compositions indicate on the packaging how to dilute it correctly for gluing or priming walls.

The composition is applied to the walls with a roller, and the corners are treated with a brush. It is recommended to prime immediately before work, so that dust does not have time to settle on the walls, which can impair adhesion. It is also worth providing the necessary conditions in the room itself. During the work, until the glue has completely dried, the windows in the room must be closed.

The most optimal temperature indoors – 20 degrees. It is also necessary to restore order and wash the floor so that when manipulating the wallpaper, it does not spoil its appearance.

Where to start gluing

From which wall will the pasting process begin? by and large doesn't matter. The main thing is to stick the first strip strictly vertically. If you don’t want to break the level, it is permissible to take some obviously vertical object (window slope or doorjamb). You can start gluing in the corners. The remaining strips will be glued according to the first reference strip and the fitting process will be simplified.

How to prepare glue correctly

All modern adhesives have back side packaging instructions on how to glue wallpaper. It is necessary to study it carefully before gluing wallpaper and follow all recommendations. As a rule, the preparation process comes down to diluting dry glue in water in the proportions indicated on the package. To prevent the formation of lumps, it is necessary to add glue to the water in small portions, thoroughly stirring the resulting composition.

How to glue wallpaper

First of all, you need to find information on the rules for applying glue on the wallpaper packaging. If the glue should be applied directly to the strips, then they must be rolled up with the coated side inward. The edges are folded towards the middle several times. The folds should remain rounded and the strip of wallpaper should resemble a scroll.

If, according to the technology, glue is applied to the wall, then it is necessary to coat the base along the width of the glued strip with a margin. To apply glue in the corners under the ceiling and floor, use a brush.

Climbing onto a stepladder, you need to launch a few centimeters of the glued strip onto the ceiling. The edge of the strip must be aligned with the marked vertical or landmark. Then, using smoothing movements from the reference point to the opposite side, glue the strip near the ceiling.

with a special soft spatula. When gluing wallpaper, you need to watch for the formation of air bubbles, be sure to expel them with excess glue to the edges.

The remaining parts are glued in the same way, you just need to focus on the already glued strip. Finally, you need to trim off the excess parts in the corners of the ceiling and floor. The easiest way is to use a wide spatula and stationery knife. The spatula is applied to the corner, and the resulting margin is trimmed along its edge. As a result, the edges are smooth.

Separately, it is worth mentioning how to paste wallpaper in the corners. There are two ways. The first one involves gluing one strip overlapping to the other side of the corner with a margin. The second strip is cut at the corner and pasted directly onto the stock. If the material is thick, the joint will be very noticeable, and it is better to use the second method.

To achieve a more invisible joint in the corners, the strips on both sides are glued overlapping and cut off using a spatula sharp knife. If the corners were glued tightly, the stripes will fit perfectly evenly. External corners the premises are glued in the same way, using one of the methods.

How to glue wallpaper when there are obstacles

For those who understand how to glue wallpaper, difficulties may arise in areas near doors and windows. If the window or door is located flush with the wall, it is enough to trim the strip of wallpaper along the trim or jamb with a small margin. Then, up to the corner of the casing, the strip is cut at an angle of 45 degrees. The resulting parts must be hidden behind the structure of the door or window, and the excess remains must be cut off.

If the door or window is located in different planes with the wall, the work becomes somewhat more complicated. First, you need to seal the slope by placing a small margin on the wall, which is trimmed along the edge using a spatula. Next, you need to seal the wall in a similar way.

Difficulties may also arise when bypassing sockets and switches. If they were dismantled before carrying out the work, then only installation boxes with wires should remain on the walls, located flush with the wall, which will not interfere with the work.

If for some reason it was not possible to remove the electrical installation parts, then you need to apply the strip to the obstacle and mark its edges. Using a knife, cut out the required fragment according to the marks, leaving a reserve that can be hidden behind the overhead decorative frame.

If you need to seal the wall behind the battery, it is not necessary to remove it. It is enough to have a certain supply of wallpaper from all over the world. You may also need information on how to properly bypass heating pipes. If they hang on clamps, you can dismantle them for convenience and put them back in place after finishing the work. Holes in the walls will not be difficult to find.

How long does it take for wallpaper to dry?

The drying time of wallpaper depends on its type. Non-woven wallpaper takes at least a day to dry, and the thicker it is, the longer you need to wait. Vinyl wallpaper dries for about two days, provided the room humidity is no more than 60%. Drying time paper wallpaper varies from 24 to 72 hours. It is important to remember that you should not open windows at this time, and generally allow drafts in the room. By following these rules, you can hope for a high-quality result.

FAQ

• Is it possible to glue wallpaper onto wallpaper? - This is allowed to be done only in certain cases. If the old samples are thin, then most likely they will sit firmly on the walls, therefore, they will be a good basis for new finishes. However, how long such wallpaper will last is a big question;
• How much do the services of craftsmen cost? - On average, finishers estimate their work from 150 to 170 rubles per glued square meter;
• What to do if the wallpaper peels off? — You can use a brush to glue the detached part with the remaining glue, or use a special glue for seams;
• What happens if you ventilate the room during and after work? — It may happen that in a draft the glue dries too quickly and the material does not have time to stick.

In one of the articles devoted to the question of whether it is possible to stick new wallpaper on old ones, we answered this question in some detail. Is it possible to stick non-woven wallpaper onto wallpaper - just special case. But, nevertheless, it is worth it to once again emphasize the need to carefully prepare walls for wallpapering and not to treat this construction and finishing work with disdain.

What are the advantages of non-woven fabric?

Non-woven base - namely, it gave the name to a whole group of wallpapers that differ in structure, density, relief and material composition; it is a semi-synthetic material based on natural cellulose. Unlike paper or fabric backing, non-woven fabric has a number of advantages:

• This is a very thin base.
• During the wetting process, the non-woven fabric does not stretch or deform.
• Non-woven fabric is vapor and air permeable.
• Old non-woven wallpaper can be easily removed.
• The service life of such wallpaper is 3-5 times longer than the service life of “traditional” wallpaper.

Why do non-woven wallpapers have so many advantages?

Non-woven fabric is a non-woven fabric consisting of cellulose fibers bonded together using adhesive components or by pressing. Due to the manufacturing technology, it contains much less chemical substances than ordinary paper.

Any material composition can be applied to the surface of the non-woven base: paper, vinyl, fabric, bamboo or cork. Most non-woven wallpapers have paper covering, varying degrees of relief, and are intended for painting with water-dispersion paints. After drying, the paint can be washed or repainted 2-3 times in a row. There are completely non-woven wallpapers - quite thick and heavy. They are easily recognized by the small shiny cellulose fibers on the outer surface of the fabric. Usually they have smooth surface and are used under paint.

Preparing the wall for the sticker

Before gluing non-woven wallpaper, if you do not want to lose all of its wonderful qualities, you should prepare the wall very well. And here, without removing the old wallpaper and oil paint, not enough. Firstly, old wallpaper over the years of use absorbs a lot of chemicals from the surrounding air - including allergens contained in house dust. Secondly, they may have defects - tears, abrasions, contamination with fats or paint that has dried with drops. All this will inevitably affect you when you start gluing new wallpaper over these defects, especially thin non-woven wallpaper, which will repeat the relief of the old wallpaper.

Third danger- swelling and detachment from the wall of a layer of old wallpaper, soaked from the action of glue for new wallpaper. This defect cannot be eliminated in any way and the newly pasted wallpaper may come off the wall along with the old ones.

The fourth danger– thin non-woven wallpaper can be stained with paint from old wallpaper or soaked in grease that was on the old wallpaper.

Fifth trouble- you deprive yourself of the main advantage of non-woven wallpaper - its vapor and air permeability. The more layers of old wallpaper you accumulate on the wall, the heavier and stale air with the smell of wet paper will be in your apartment.

You cannot paint non-woven wallpaper pasted onto old wallpaper or oil-based paint, since under the influence of moisture, the old paper ones that did not fall off during pasting, saturated with water contained in the paint, will definitely peel off from the wall.

How to stick non-woven wallpaper on plaster?

Gluing non-woven wallpaper onto plaster is the most common method. It is only important before starting pasting to level the plaster with sandpaper (with an abrasive mesh on a block and treat the surface of the plaster with putty. If you use finishing plaster with a fine grain size, you can do without putty. But after treating the plaster with sandpaper, you need to sweep it with a broom and treat it with a primer (acrylic) .

It is advisable to use plaster as a base for gluing non-woven wallpaper to preserve the “breathable” properties of the wallpaper. In damp rooms, you can add PVA emulsion or liquid glass to the plaster. This will increase resistance to mold formation and wetness of external walls.

If the walls under the old wallpaper are already plastered, after removing the wallpaper, you should carefully inspect the plaster.

Carefully fill all cracks and defects, and old plaster, before gluing new wallpaper, treat with a primer.

What to do if there is no way to remove old wallpaper?

But even in the most hopeless situations- there is a way out. To reduce the risk of old wallpaper peeling and achieve an acceptable result. By gluing new non-woven wallpaper, you can create a waterproof coating on the surface of the old wallpaper. This can be done: either by treating the old wallpaper with an aqueous solution of PVA emulsion, or with silicate ( liquid glass), and oil paint with sandpaper. In both cases, a thin waterproof film is formed on the surface of the paper wallpaper, susceptible to most types of wallpaper glue (based on modified starch).

Before gluing new wallpaper, you can add PVA emulsion or bustylate glue to standard glue - its adhesive characteristics will only increase. True, you have to forget about the breathability of the wallpaper.

There is no need to paint non-woven wallpaper pasted in this way.

Even despite the waterproofing layer, it is still very conditional. By applying paint to new wallpaper, old wallpaper can become saturated with moisture and peel off from the wall.
