How to put new wallpaper on old ones. Is it possible to glue new wallpaper onto old ones?

Anyone who has done renovations at least once in their life knows perfectly well what a labor-intensive and dirty process it is. First you need to remove the old ones, clean the wall well, prime it, then apply it and only after that glue the new canvases. Some people skip the preparation stage and immediately glue on old finishing. Whether this is good or not is a moot point. In this article we will try to figure out how to glue wallpaper onto wallpaper, what are the advantages and disadvantages of such technology, and whether it is necessary to do this at all.

Advantages and disadvantages of gluing wallpaper over old canvas

Before we begin describing the gluing methods various types wallpaper on the old coating and how to do it correctly, you need to consider the advantages and disadvantages of such technology. Knowing the pros and cons of technology or materials helps to avoid mistakes when choosing.

The advantages of gluing new wallpaper onto an old coating include the following:

Unfortunately, this technology also has its drawbacks:

inability to correct surface defects;
Poor adhesion between old and new canvases is possible;
even if the gluing was done efficiently, there is a possibility that after some time the new wallpaper will begin to lag behind the old coating, which naturally shortens its service life;
If the old layer of wallpaper begins to peel away from the wall, you will have to re-glue everything in the room again.

There is another drawback in the form of air bubbles. Sometimes they smooth out on their own, and in some cases they can be removed with heat or a needle prick. If none of the above helped, then you will have to redo everything and completely remove the old coating, and this additional expenses time and money.

Is it possible to put wallpaper on wallpaper, and when is it allowed?

Gluing onto an old coating is possible in several cases. For example, a room is covered with thin paper wallpaper and it is of such high quality that the canvas cannot be removed from the wall surface. In this case, it is enough to purchase new wallpaper, a high-quality adhesive composition and prepare it correctly to ensure high-quality adhesion between the finishing materials.

Pasting old wallpaper with new canvases is possible only if the following conditions are met:

old wallpaper that will be used as a base must be thin enough, made entirely of paper and properly glued to the wall surface. If one of these conditions is not met, then the old wallpaper must be removed;
using only high-quality adhesive composition, which must be prepared in full accordance with the manufacturer’s instructions. Before applying glue to old wallpaper, you need to soak it well in order to get good adhesion between both sheets and the wall.

Ask a Question

"Before gluing new ones, you need to make sure that the coloring substances of the old coating will not bleed through the material being glued. To do this, you need to apply a damp sponge to the wall and hold it for a while. If traces of paint remain on the sponge, the walls will need to be treated with a special compound, which will prevent the bleed through of dyes.

Is it possible to put new non-woven wallpaper on the old coating?

Non-woven wallpaper is made from compressed paper or fabric fibers, which gives this finishing material high strength. This type of wallpaper is quite heavy and thick, so gluing non-woven fabric onto the old covering will not be possible. best idea, since the weight of the finish can cause the material to peel off from the wall. Air bubbles are also likely to form, which will spoil aesthetic appearance wallpaper There is also a possibility that the pattern of the old wallpaper will show through new finishing.

Before you apply the old coating, you need to be sure that it is paper based and holds firmly. Although the most ideal option would be if you still clean the wall of the previous finish, thoroughly clean it and only after that glue new wallpaper.

Is it possible to apply liquid wallpaper to an old similar coating?

Experienced craftsmen allow applying a similar coating to an old one, provided that it was done correctly, cleaned of dirt, stains, and there is no major damage. If the old ones have chips or scratches, then you need to thoroughly moisten this area and smooth it out. To prevent the old layer from showing through the new one, it is recommended to treat the surface with a water-based emulsion to match the color of the future wallpaper.

Is it possible to glue new wallpaper before painting?

How to glue wallpaper on, and is it even possible to do this? This question is asked by many people who decide to do express repairs. In principle, anything is possible, but the result can be unpredictable. If you decide to put new wallpaper on old painted canvases, then be prepared for the fact that paint or a relief pattern from the previous finish may show through, and then you will have to redo everything and completely clean the wall down to the concrete.

Is it possible to glue photo wallpaper onto wallpaper?

Additionally, high-quality furniture will help decorate the interior of the room. This type of finishing material is demanding on the base, so it is advisable to prepare the wall surface well for pasting. If you decide to glue photo wallpaper onto existing wallpaper, then a number of conditions must be met:

the depth of the textured pattern of the old finish should not exceed 0.2−0.3 mm;
density of photo wallpaper - at least 200 g/m2;
The wallpaper that will serve as the base must adhere well to the wall and be moisture resistant.

If old or new wallpaper does not meet the above requirements, then it is better to abandon this idea, remove the previous finish, clean and prime the wall.

Carrying out preparatory work before wallpapering

Before gluing the wallpaper, you need to draw a row preparatory work, which will allow you to finish the walls with high quality and for a long time. You need to start with preparing the walls, namely:

cleaning the surface from old finishes;
leveling the walls (if necessary);
padding.

How to prepare walls before wallpapering

To prepare walls for wallpapering, you will need to prepare certain tools and materials. To remove the old finish, you will need a spatula, a spray bottle of water or special solution, metal scraper or metal brush. You will also need starting and finishing putty, serpyanka for sealing seams and cracks, primer ( deep penetration or universal). All this can be purchased at the market or at a building materials store.

To prepare walls for wallpapering, follow these steps:

the wall must be cleaned of old finishes - wallpaper or paint;
surface if necessary;
seal all cracks and holes.

Wall preparation is very important, since the quality of the finish, its durability, material consumption and, accordingly, costs largely depend on it.

The video shows the process of preparing the surface for wallpapering:

Priming the walls before wallpapering

After cleaning and leveling the walls, the following important stage is their priming. Applying a primer is necessary for several reasons, namely:

impregnation of walls increases the adhesion of wallpaper to the surface;
primer is necessary to eliminate mold and mildew and also to prevent them further development and distribution;
The base is strengthened by filling microcracks with a primer.

For optimal adhesion of the wallpaper to the base, it is necessary to apply several layers of primer. On average, 100−350 ml/m2 is required. This depends on the type of primer, the quality and density of the finishing material, as well as the condition of the surface.

How to glue wallpaper correctly to achieve a good result

So, we found out that for high-quality wallpapering you need to remove the old covering, level, putty and prime the walls. But that's not all. Before you hang wallpaper beautifully, you must first decide on the type of finishing material, its design, glue and, of course, the necessary tools.

Required tools and materials:

glue;
container for glue;
stationery knife;
roller or wide brush for applying glue;
plastic spatula;
paper tape for joints;
clean rags.

Before gluing new wallpaper onto the old trim, you need to make sure that it is thin and firmly glued to the wall. If the bottom sheets are not made of paper, then it is better to abandon the idea of gluing new wallpaper onto old ones.

How to choose wallpaper

It is clear that before gluing wallpaper, you first need to select and buy it. Today's market offers big choice construction and finishing materials. When choosing quality wallpaper You need to pay attention to several basic criteria.

First, you need to decide on the type of wallpaper - paper, textile, non-woven, vinyl, etc. Secondly, wallpaper can be smooth, embossed and imitating different textures various materials. Also this finishing material differs in moisture resistance: classic (without any protection), moisture-resistant, washable and super-washable wallpaper. And one more important criterion, which you need to pay attention to is the density of the material. According to the degree of density, wallpaper can be divided into light (100 g/m2) and heavy (more than 110 g/m2).

Wallpapering options

Previously, during renovations, they selected one wallpaper design and simply glued it on. Now thanks large assortment construction and finishing materials have expanded and the capabilities of designers have expanded. Now, when creating an interior, you can use a combination of colors, textures and various materials. Examples are shown in the photo below:

What glue is best to use when gluing wallpaper?

When choosing wallpaper glue, you should consider the type of finishing material:

paper– glue for light wallpaper;
vinyl and non-woven– Moment, PVA, Bustilat or special mixtures for “ vinyl wallpaper" and "non-woven wallpaper";
textile– special glue for textile or heavy wallpaper;
cork– only special glue for cork wallpaper.

How to properly hang wallpaper in the corners of a room

When straight sections of the wall are to be pasted, problems are usually not foreseen; the situation is more complicated when it is necessary to finish the internal or external corners, and hard to reach places. It makes the job much easier if the corners have been pre-aligned. But what if there is no correct geometry?

First of all, you need to decide where to glue the wallpaper from - from or. Previously, when there was only paper wallpaper, they were glued from the window. This was due to the fact that they were glued “overlapping”, and when moving away from the window such joints were less noticeable. Modern wallpaper Basically they are glued joint to joint, and now most people push away from the door, which, in general, is more correct. But when it comes to the corner, the problems begin.

First you need to coat the corner well with glue. Next, the canvas is glued so that it overlaps the other wall by 20-30 mm. The next strip is glued overlapping the previous one. Such a joint in a corner will not be as noticeable as on a straight section of the wall.

External corners are covered in two ways. If the corner is even, then you can immediately stick the wallpaper on the corner, measure the vertical and cut the canvas so that the rest also lay perfectly flat. In the second option, the corner can be pasted over with two stripes, and their joint can be decorated with a special corner. The joint can be decorated with a plastic corner.

How to hang wallpaper on the ceiling yourself

One of the options for finishing the ceiling is wallpapering. But if it can be difficult to stick canvases on the wall, then on the ceiling it is much more difficult, but possible. As with walls, the ceiling surface also requires similar preparation. To make the work easier, it is best to work with an assistant: one below, and the other on a table or stepladder.

If it is necessary to glue paper or vinyl wallpaper, then the glue is applied directly to the canvas. The adhesive composition on vinyl wallpaper must be left on for several minutes; paper sheets must be laid immediately. If it is non-woven wallpaper, then the adhesive is applied to the ceiling.

So, you have started renovating your apartment, and one of the design project items is wallpapering the wall surfaces. This work does not fall into the category of very complex, but it does have its own subtleties, so it is advisable to clarify even before the pasting process what nuances you will have to face when performing this work.
What mandatory tasks will have to be solved? First of all, it is necessary to prepare the wall surfaces - they must be perfectly leveled and brought to the maximum high degree smoothness.

Quite often, from ordinary people who decide to carry out repairs on their own, you can hear a strange question: “Is it possible to stick new wallpaper material on top of old wallpaper and how to do this?” This suggests that the owners do not want to waste time on removing old wallpaper material, removing defects and flaws on the walls and other work that precedes the high-quality preparation of the wall surface for wallpapering. Why did we consider this question itself strange? Yes, because the repair process, at any level of complexity (it is generally accepted that there are three types of repairs - European-quality repair, major and cosmetic) involves the complete dismantling of old finishing materials. So it is advisable to remove old wallpaper during any renovation.

So why do some people want to keep old wallpaper? On the surface there are two reasons. The first is explained by ordinary human laziness, because you don’t really want to tinker with the same finishing materials for a long time when doing repairs yourself. And the second is the desire to save some money. According to the logic of such ordinary people, dismantling old, worn-out coatings costs big money.

Although you will actually have to spend money on a certain amount warm water with little effort. Another thing is that the wall surface will have to be removed from defects and imperfections, such as cracks, chips, gouges and others, and also carefully leveled. But this will not entail large costs - for these purposes you will need a small amount of primer and putty.

So everything suggests that the old finishing material should be removed. But if you are categorical, then new wallpaper can be pasted over the old wallpaper material.

Criteria

So, you have decided that you will not dismantle the old wallpaper. Well, your right, but you should take into account that the new wallpaper will have to be glued in strict accordance with the requirements technical rules and standards required when performing the repair process. They imply two criteria - the wall surface must certainly be smooth and durable. Therefore, work should begin with an examination of the wall surface to identify obvious and hidden defects.
Obvious defects are torn and peeled parts of wallpaper visible to the naked eye, their tears and abrasions, and more. And, of course, differences in plane on the wall surface.

Other defects (hidden), invisible to the eye, in the form of cracks, chips, voids and others can be identified by tapping the wall using, for example, a hammer. When such defects are discovered, specialists, as a rule, do not take risks and prefer to get rid of the old wallpaper and carry out preparatory work in full.
Well, if you are lucky and there are no defects on the walls, you can calmly and confidently begin the process of gluing new wallpaper over the old ones. But even in this case, it is necessary to fulfill certain preparatory activities.

You should not waste time and effort on gluing new wallpaper over the old vinyl counterparts. This is due to the fact that vinyl has a repellent property for both moisture and water, as well as adhesive mixtures.

In addition, it should be borne in mind that vinyl wallpaper mainly has a relief structure, which does not allow us to talk about the evenness of the surface. The above fully applies to another category of products - non-woven wallpaper, which also contains vinyl (it makes the top outer covering). Therefore, if we talk about sticking some wallpaper on top of others, we mean that the old paper wallpaper remains.

Materials and tools

The topic should begin with the fact that any self-respecting specialist, before starting repair work, spends some time carefully preparing for it, so that during the work process itself you are no longer distracted by various little things. Particular attention should be paid to the tool that should be at your fingertips at any time:

Paint roller and special bath. Their presence makes it easier and faster to apply glue to the surface of the wall or to the underside of the wallpaper.
Scissors. These can be ordinary scissors used in everyday life or specially designed for wallpaper.
Sharp knife. With its help, you can make a cut at the joint in the corner of the room.
Putty knife. With this tool you can level the laid wallpaper. Most in in this case A rubber spatula will do.
Also, you should always have clean rags on hand to wipe away glue drips, which in any case will protrude beyond the edge of the wallpaper after smoothing it.
Perhaps you can easily do without a wallpaper table with a flat surface; it can easily be replaced by a floor surface. And, nevertheless, the presence of such an item will greatly simplify the work and make it more comfortable.

Step-by-step application of one wallpaper to another.

First of all, the surface of the wall must be thoroughly primed. It is better if you use glue as a primer - the same one that is used for wallpapering. But there is a condition - the glue should be brought to a liquid state, only in this case it will lie well on the surface. It's better to apply it paint roller, one layer of coating is quite enough. You can start wallpapering only after the primer has dried thoroughly.

The next stage is preparing the wallpaper. A standard roll allows you to cut the roll into three strips, each of which is enough to completely cover a section of the wall. In addition, a small allowance will protect you from any surprises. If a pattern is applied to the wallpaper, the canvas must be trimmed in such a way that there is a complete match of the patterns on two adjacent strips.

The adhesive mixture must be prepared strictly following the instructions indicated on the packaging, after which it can be applied to one of two elements - on the surface of the wall in case of subsequent wallpapering of the walls with vinyl wallpaper or on the back side of the wallpaper if paper products are used. An indispensable condition when applying glue is a sense of proportion; the surface must be coated with a uniform, medium-thick layer. Otherwise the process is exactly the same traditional way wallpapering walls.

We remind you:

covering walls with wallpaper should start from any corner of the room;
Initially, the wallpaper strip needs to be lifted into the ceiling part of the wall, and then the strip should be straightened from top to bottom;
level the canvas while squeezing out air bubbles;
smoothing the wallpaper strip must be done from top to bottom and at the same time from the center of the canvas to the edges;
for smoothing, it is advisable to use a rubber spatula or clean soft cloths;
You also need to use a clean soft cloth to remove any remaining adhesive mixture from the edges of the canvas.

The second and subsequent canvases are laid in the same order. The difference may vary depending on the type of wallpaper. In one case, they are laid end-to-end, and in the other - overlapping. This depends on the material from which the products are made. As a rule, paper wallpapers are laid overlapping, and non-woven or vinyl wallpapers are laid end-to-end.

The biggest difficulty in the process of laying wallpaper occurs when sticking it in the corners of the room. There is a special technique for laying wallpaper strips. To perform this complex type of installation finishing product it is necessary to reduce the width of one of the canvases and trim it with an allowance of about five centimeters. This allowance, intended for moving to another wall, does not need to be coated with glue. We do the same with the second canvas on the adjacent wall (the same allowance of five to six centimeters, on which glue should not be applied).

Now comes the turn of a sharp knife, which the master should have among other tools. Using a knife, exactly along the angle in the vertical direction, we make an incision along both panels, from the ceiling to the floor. The waste from the allowances of both strips is removed, and the edges at the junction, that is, the corner part on the wall side, are treated with an adhesive mixture and smoothed with a rubber spatula.

During the preparatory work, the joints of old wallpaper that you decided not to remove from the wall should be carefully taped. You should also not lose sight of the fact that if old wallpaper releases a dye as a result of contact with water, then it is better not to stick new wallpaper material on it.

If old finishing coating had bright patterns or designs, and the prepared new wallpaper has a fine structure, then it is better to remove the old wallpaper. As we have already mentioned, do not get carried away with applying a large amount of glue; too much of it can harm old wallpaper by soaking the old adhesive layer.

So, we have introduced you to the technology of wallpapering without removing the old wallpaper. As you can see, there is no particular difficulty, however, before starting such work, we advise you to carefully consider whether this option is worth using. Perhaps it is still better and more practical to completely remove the old coating and thoroughly treat the walls, after which you can confidently glue any wallpaper.

One of the most popular types of room decoration is wallpapering. But in order for the result to please you, you need to know how to glue wallpaper correctly. There are a sufficient number of nuances that affect the quality of the finish.

Preparatory stage

First, everything in the room that can be removed is removed, including door frames and baseboards, if possible. They also remove sockets and switches, closing the boxes with wires with plugs - plastic or wooden.

Turn off electrical outlets

When working with electricity, we de-energize the room and do not turn it on until we are finished. It is advisable to carry out all work, including wallpapering, with the power turned off. The work is “wet”, and water or glue can get on the wires and short out. If the wiring is done according to all the rules and there are protective circuit breakers, this is not a big deal. They'll just turn off the power and that's it.

If the wiring is still done in the old way, it can be dangerous. The worst part is that in this case there is often no way to turn off the power in a separate room. Only in the entire apartment or, in best case scenario, in her half. Then the solution is to remove the power wires from the sockets and switches (with the power off, of course) and carefully insulate the ends, then hiding them under plugs. Then you will have to unwind them and put them back in place, but it will be safe.

Lighting during work is temporary - extension cords are pulled from other rooms and turned on portable lamps. Once you have dealt with electricity, you can move on.

Sealing irregularities

Here you will first have to assess the condition of the walls. First you need to remove all the nails and screws, remove chips and repair cracks. Then examine the results. If the walls are more or less even, there are only small defects, you can get by with occasional leveling. Only cracks, dents and chips are repaired. They can be covered with finishing putty. Just before leveling, completely clean the wall of dust and pieces of wallpaper, and then cover it with a primer (with a wall roller and a brush in the corners).

If the wall has been “treated” with a hammer drill, you cannot do without full putty of the entire wall. Mostly today they use gypsum putty. First, apply a layer of primary or starting. It has a coarser grain and the layer can be up to 3-5 mm. This composition is used to level out the main unevenness, trying to achieve flat surface. After drying, they pass through a special mesh, removing any unevenness or sagging that may exist.

After being used finishing putty. It is very flexible and can be applied thin layer- up to 1-2 mm. After this, the wall becomes smooth (after the irregularities have been smoothed out with a mesh, only with a smaller mesh).

Primer of walls

The second layer of primer is applied after puttying. It forms a film on the surface that reduces the absorption of the glue and also improves adhesion. For wallpapering, you can use a thinner wallpaper glue as a primer. Each pack has a table indicating the amount of water for gluing and priming. We dilute the glue in the required proportion, wait for it to be ready (also on the package) and cover the walls with the composition. The priming technique is the same: first go over the corners with a brush, then with a roller on smooth surfaces.

In the video, for some reason, the use of primary putty is called plaster, but otherwise the sequence of actions is presented correctly.

Rules for gluing

When wallpapering there are several rules that must be followed. The technique varies depending on the type of wallpaper, as does the glue, which is necessary for a quality result. the difference is mainly in when and where to apply the glue. You don't have to guess. Everything is on the insert, which is included on each roll of wallpaper. There it is graphically depicted, and in some it is written, which part should be coated with glue: only the wall or only the wallpaper, or maybe both at once.

But some things remain the same. For example, applying a starting strip.

Where to start

In reality, the starting location is not that important. It is important that the first strip is glued strictly vertically. Therefore, the choice is yours.

If the room has a perfectly designed corner: smooth and exactly vertical, you can start from there. You can start from a door with a perfectly aligned jamb. If there is nothing like that, draw a guideline for yourself. Take a building level, mark a point on the wall and draw an exact vertical line through it. Inexpensive building levels household grade, which we usually use for repairs, sometimes give a significant error. And since it is important for us to stick the first strip strictly vertically, check the accuracy of the line using a plumb line. He never lies, pointing straight down. If everything is fine, you will align the edge of the strip along this line.

If you still haven’t decided where to start gluing wallpaper and this is your first experience in this area, start with the wall that is least visible. For example, the one along which there is a closet. The first couple of pages will be difficult for you, but then you will better understand what’s what and there will be fewer flaws.

How to glue wallpaper on a wall

If glue, at the request of the manufacturers, is applied to the cut fragment, the smeared strip is folded so that the coated side is inside. To do this, fold the edges towards the middle, then fold them several more times. The folds are not pressed. Let them remain round. This is necessary so that all layers are saturated and the canvas fits well on the wall and also sticks without bubbles.

If you need to apply glue to the wall, coat an area slightly larger than the width of the wallpaper. The area under the ceiling, in the corner and near the floor is coated with a brush. Then the rules are general.

Take the cut strip and climb up the stepladder. Place the top edge a few centimeters on the ceiling, then align one of the edges along the drawn “start” line. Since wallpaper today is glued end-to-end, it doesn’t matter which edge.

Strictly attaching the side edge to the line, moving from this line to the other edge, glue the wallpaper in the ceiling area. Then, gradually moving down, you go down a little lower.

Extra centimeters on the ceiling are cut off. It is more convenient to do this with a paper knife and a large spatula. Press the paper well against the corner by running your hand. Then apply a spatula. Run a knife blade along its edge.

Trimming under the ceiling and near the baseboard

When gluing the canvases, movements are made from the center of the strip to the side and slightly downward, expelling the trapped air to the edges. Previously, this was done with a rag, but it works better and faster with a roller with an elastic nozzle (it is usually yellow color). There are practically no bubbles when working with it. But if the wallpaper is structural, with an embossed pattern, you can crumple it with a roller. Then take a wallpaper brush. It is wide and flat, with hard pile.

Wallpaper brush for quick pasting

Having reached the place where the strip is not yet glued, unroll the rest tightly and proceed according to the same pattern. First, you expose the edge, then use a roller or rag to expel the air, achieving a flat surface.

The second strip is glued in exactly the same way, with the only difference being that the canvas already on the wall will serve as a guide for gluing the edge. That’s why it’s important to glue it evenly, otherwise everyone else will also be mowed.

Secrets of pasting corners

The most difficult part to glue wallpaper correctly is in the corners. But this is only until you know the secret. You can try to do it simple at first. Wrap one of the parts onto the adjacent wall by 1-2 cm, and cut the second at the corner.

It’s not difficult to do, this method looks good. But on some wallpapers this stripe is very visible. For such a case, there is another way. Glue the canvases on both sides of the corner so that they wrap at least a little on the other side (2-3 cm is enough). Press well so that they fit exactly. to the walls and corner.

Then take a special cutter or large spatula. Press it in the corner, cut the wallpaper along its edge sharp knife. It is necessary to cut both sheets at the same time, so considerable effort may be required. To ensure a continuous cut, do not tear off the knife. Having stopped, move the spatula, which you rest against the blade and then continue the cut.

Having cut everything off, remove both cut strips and join the remaining strips in the corner. If the wallpaper was pressed well before trimming, the match is perfect, without any discrepancies.

How to glue wallpaper on outside corners? Almost in the same ways. In the first case, one of the stripes is wrapped around the corner by one or two centimeters (for thicker wallpapers, 2 cm is better, for thin ones, 1 cm is enough). The second strip is glued strictly along the corner. If this overlap is visible (usually on non-woven wallpaper), you will need to cut along the entire strip. In this case, we wrap more and cut vertically using the same spatula and knife. We remove the cut and glue the joint.

Meter-long wallpaper in the corners is glued in the same way as narrower ones. It happens that a narrow strip is needed in a corner, and the rest is cut off. If the wallpaper is without a pattern, it can be used somewhere, at least in another corner. With patterned canvases, sometimes it is also possible to attach them somewhere, but this is more difficult to do. That’s why they take patterned ones with a decent supply: just for such cases.

How to glue wallpaper near doors and windows

If the door or window is flush with the plane of the wall, problems usually do not arise. Wallpaper is cut lengthwise door frame or along the edge of the platbands. The canvas is cut at an angle of about 45° to the corner of the casing or frame. The cut parts are wrapped along the opening, bent and then cut off with scissors or a knife. It’s smoother and faster using a knife and spatula.

How to glue near the door

The option that causes more difficulties is when it is necessary to cover the slope of a door or window. Using paper wallpaper The principle is again simple: glue the strip onto the slope, bringing it 1 cm onto the wall. We glue a piece on top exactly along the cut of the window opening.

But this method will not work with wallpaper on non-woven fabric: the “overlap” is too visible. In this case, the strip is cut along the window opening with a small margin. Another fragment is glued on top with an overlap, cutting them exactly along the cut of the window opening. The glued piece is wrapped inside, onto the slope. Then they join as before.

It's difficult to explain in words. It’s more accessible in video. By the way, it also contains a story about the design of wallpaper for arched openings.

How to make joints invisible

Care must be taken to ensure that the joints of the canvases are invisible during gluing. You need to connect the canvases so that there is no gap between them, but also so that they do not overlap one another even by a millimeter. A perfect match must be achieved.

Since we, alas, rarely see perfectly smooth walls, it turns out that the seam either creeps in a little or diverges. Your task is to move the canvas so that it becomes perfect and invisible. You can move the canvases with your hands - they can slightly stretch and contract. Due to this, you achieve the required match. If the resulting defect is too large and nothing can be achieved by shifting, the strip is peeled off to this place and, having corrected it as necessary, is glued again. Sometimes, if the seam is sticking out a little, rolling it with a special tapered roller can help.

With this technique, it turns out that first the edge is glued, which is joined, and then, from it, they begin to smooth out the rest of the surface of the canvas. If you have examined the seam and are satisfied with the result, take a clean rag and wipe it off any excess glue that may have come out during all these actions.

Eliminating shortcomings

If there is a lack of experience, it may happen that bubbles appear on the walls after or during drying. You can remove them with simple steps. Take a large syringe, fill it with glue, pierce the bubble and inject some glue into it. Vinyl wallpaper, acrylic, paper - the top part is unimportant. The actions vary depending on the basis. If the wallpaper is paper-based, wait five to seven minutes; if it is non-woven, act immediately.

How to remove bubbles from wallpaper

Seams come apart quite often. Wallpaper may peel along the thread or baseboard. There are two ways to glue them. Use a brush and the remaining glue or buy a special one for seams. It comes in a tube and is applied precisely. And again, the procedure depends on the base. After wetting the paper, wait a while, then glue it, making sure the edges match.

New wallpaper on top of old? It is unlikely that anyone will recommend this option for decorating a room, regardless of what types of wallpaper you have to deal with.

But the desire to save money, and sometimes other factors still encourage people to do this, especially for those who decide to do the repairs themselves.

By gluing new non-woven wallpaper, you can create a waterproof coating on the surface of the old wallpaper. Be sure to before gluing new wallpaper in standard glue add PVA emulsion or bustylate glue - its adhesive characteristics will only increase.

Helpful information:

Well, such experiments are not prohibited, but it is advisable to learn at least the basic rules, otherwise, instead of saving, you may encounter additional material and time costs.

General rules

Pasting new wallpaper without removing the old ones is very simple; you can do it yourself, but then there is the possibility of unpleasant surprises:

“reluctance” of fresh wallpaper to stick to the wall - the surface bubbles or new wallpaper comes off along with a layer of old ones;
sloppy appearance surfaces - the inner finishing layer shines through the newly created one, or, what is even more unpleasant, paint from the old wallpaper seeps to the top.

There is no proven recipe for dealing with the first problem, but there are a number of recommendations:

First make sure that the original layer of wallpaper is strong and free of defects - if it is uneven, peels off in places, has dents or bubbles, then another sheet pasted on top will only worsen the situation;
It is not advisable to glue any wallpaper over a relief coating; the old wallpaper will most likely remain, but the new ones will not hold tightly, the same applies to non-woven or vinyl wallpaper without relief - their outer surface simply will not absorb the glue;
You should not try to renew a wall covered with thick wallpaper; most often this measure speeds up the process of both layers peeling off.

Now you can understand that gluing wallpaper onto non-woven wallpaper hardly makes sense. Even if high-quality glue was used for the first layer, you can and should, after making cuts on them, soak the wallpaper, remove it and prepare the wall properly.

However, you can do otherwise if we are talking about wallpaper on a non-woven basis, then it is considered acceptable to leave the non-woven material, removing only the vinyl layer. But it is advisable to glue wallpaper of a similar type onto it (non-woven or vinyl-non-woven).

Pasting over old wallpaper

If the original wallpaper is thin, paper and holds up well, then you can take a chance, keeping in mind the “color” nuances:

The canvas for the second layer should be darker in tone and denser in structure;
Old wallpaper with bright patterns should not be glued to light wallpaper without any drawing, unless of course there is a desire to get the unusual effect of unevenly translucent fragments.
It is advisable to make sure that the first layer (if it is colored) will not stain the new one with coloring pigments. To do this, you need to stick a small piece of newspaper on it and check whether the paint will penetrate to the top.

The general recommendation when wallpapering again is to use the glue carefully, keeping in mind that its excess can lead to excessive wetting of the old wallpaper. Moisture will make it easier for them to peel off from the wall, naturally, along with new ones.

You can argue for a long time and nervously about how to properly glue the wallpaper with a second layer, or you can spend the same time carefully doing it without risking anything. And then you can choose absolutely any color, and not the one that is designed to hide the presence of old wallpaper.
