In construction practice, non-woven, textile, cork, bamboo or vinyl wallpapers are glued joint to joint, that is, in a way where the edges of the canvases are applied to each other and do not allow overlap.
Non-woven, textile, cork, bamboo or vinyl wallpapers are glued using the joint-to-joint method.
Why are the listed types of materials glued this way? The thing is that these samples have a thick, dense structure. When gluing them overlapping (when the joints overlap each other), a thick seam is formed on the surface, which does not look good on the walls or simply cannot stick to the applied fabric.
In order to comply with the technology, it is necessary, first of all:
To carry out the above operations, the master must have a set of the following tools:

To properly prepare for gluing walls, you should:
When the adhesive and fungicidal compositions have dried, the walls can be considered completely ready for gluing.

You can check whether the walls are completely ready for pasting using a piece of cellophane film. To do this you need to do the following:
If after 24 hours inside film, evaporation (small drops of water) is formed, which means that the surface is not dry enough, and it is too early to start gluing work. If the cellophane is completely dry and there are no drops of water on its inner surface, then the walls are well prepared and can be covered with any material.

Craftsmen glue wallpaper directly from a roll, but non-professional craftsmen are advised to cut the rolls according to the geometry of the room.
Figure 1. Rapport is the length of a pattern repeated on a piece of wallpaper.
A roll of wallpaper is initially rolled out on the floor, then cut according to length, matching the pattern, and then cut using sharp stationery scissors into appropriate sheets.
Samples with large or embossed patterns require special care when working. To correctly cut panels with a pattern, you should carefully study the label and find a repeat on it. Rapport is the length of the pattern that is repeated on the wallpaper. Marking using repeat is considered the most economical (Fig. 1).
If the wallpaper is cut using rapport, the craftsman needs to make a calculation. For example, if the size of the repeat is 60 cm, the height of the wall is 2800 cm. It is necessary to distribute an integer number of repeats along the height of the panel. That is, you need to multiply 60 by 5 and get total length panel equal to 3000 cm. It is this length that should be measured on the roll panel.
When the panel is cut to 3000 cm, it should be cut into sheets, and the sheets should be stacked. Balances in in this case should not be thrown away, as they may be useful for pasting walls under radiators, window sills, above windows or behind cabinets.

Marking walls is an important procedure. Marking the walls is done using a pencil and a laser level. When the level sets the vertical, using a pencil on the wall, draw a vertical line along the entire length of the wall. Wallpapering begins from this straight line (Fig. 3).
Scheme of puttying wall joints.
Where is the best place to start marking? If the pasting is intended to be non-woven, cork or vinyl wallpaper, the marking point does not matter. Walls can be marked from the middle of the wall or from its beginning, since in the corners such wallpaper is glued in a completely different way.
How to prepare glue for use? should be done strictly according to the instructions provided by the manufacturer. The glue should be diluted immediately before work, in a deep plastic or enamel bucket.
How then? Let's look at the technology of wallpaper gluing using the example of the most popular type, i.e. vinyl wallpaper. Vinyl wallpaper consists of two layers:
Due to the presence of two layers in the wallpaper, they are highly durable, reliable and durable, but are quite heavy for an unprofessional craftsman. It is better to glue them together. One worker should stand on a stepladder, the other on the floor.
Renovation is an important and exciting episode of life. Alas, it is often associated with significant material costs, which peace of mind do not add. At some stages of interior renovation it is not worth saving, but some of them can be done independently, which will significantly reduce the expenditure side of the family budget.
Wallpaper glued without visible seams will create an ideal picture on the walls.
For example, you can paste wallpaper yourself. And so that the walls have perfect view, just choose correct coverage, enlist the help of an assistant, understand the technology. And, of course, choose a technique that is suitable specifically for your type of wallpaper.
What should a wall be like to be called ideal? Smooth, with an even coating, without visible flaws. To achieve this effect, you need to take into account all the subtleties:
To apply wallpaper, the walls must be perfectly smooth.

You should choose a technique for gluing wallpaper based on its type. A technique suitable for vinyl wallpaper will not give a satisfactory result when gluing paper wallpaper, and vice versa.
The most difficult thing is to avoid the formation of a noticeable seam when gluing paper wallpaper. They must first be thoroughly coated with glue and left for some time to soak. You also need to lubricate the wall with glue. When swelling, the canvas may change size, especially for inexpensive collections. To make the seam invisible, you need to glue the wallpaper with minimal overlap, but it is extremely difficult for non-professionals to do this. You can use special paper; a thin strip of it is glued along the joint line under the wallpaper; it securely fixes the edges of the canvases and does not allow them to diverge. Also, beginners can paint over the joint after drying with paint of a suitable shade. To ensure that the result meets your expectations, it is better to entrust the work to professionals or choose a less capricious coating.
Modern vinyl coverings look presentable. It is quite simple to stick this type of wallpaper well. It is necessary to first lubricate the wall and canvas with glue and, after swelling, begin to work. It is noteworthy that even when wet, they do not change size, and you can be sure that the seams will not come apart during the drying process. Vinyl wallpaper is glued, starting from the top, gradually moving towards the floor. The fabric should be smoothed immediately using a roller. Additionally, you can be on the safe side by using a special glue for joints, which is packaged in a tube with a sharp spout. After 2 canvases are glued, the seam is additionally treated with this glue, immediately smoothing the joint with a roller. Having figured out how to hang wallpaper of this type, it will not be difficult to cope with other types of coatings.
It's even easier to hang non-woven wallpaper. They do not require applying glue to the canvas, only to the wall. This avoids deformation during the drying process and, as a result, a noticeable seam. Non-woven wallpaper is glued end-to-end, without layering or gaps. Coatings that require subsequent painting are especially popular. Perfect wallpaper without seams - it is a non-woven base coated with paint of a suitable shade.
If you need to match the wallpaper different types, you should use the pruning method. To do this, you need to glue the canvases with an overlap of 3-5 cm, then cut both layers with a very sharp stationery knife, be sure to use laser level or a ruler. All that remains is to remove the unnecessary layer. The seam will be amazingly smooth.
When we plan a renovation, we naturally want everything to go smoothly, and in the end the renovated apartment will look attractive. In this case, special attention, as always, is paid to the walls, since they largely help shape the style of the interior of the apartment. That’s why everyone wants the wallpaper to be hung with high quality, without visible seams or other flaws. However, in order to ensure that the seams between the wallpaper are not visible and do not separate after the glue dries, it is necessary to strictly follow the correct gluing technology.
Wallpaper can be hung flawlessly
So, let's take a closer look at how to properly glue canvases, how to hide visible joints, and how to properly seal them in cases where the junctions of individual canvases are still noticeable.
Before learning how to properly hide joints, let's take a quick look at why they may still be visible. It should be immediately noted that there may be several reasons for this:
It must be said that in Lately, unlike the Soviet era, a significant part of the wallpaper sold in stores is designed to be applied end-to-end, rather than overlapped. This is what allows the seams to be made invisible even from a close distance, especially in cases where the design or pattern on the adjacent canvases is correctly selected.
It is important the right approach to prepare the wall surface. You can start gluing only after the wall has been processed according to all standards, that is, puttied, leveled and treated with a primer. You can read about how to properly prepare walls before you start wallpapering in this article.
Attention! It should be understood that wallpaper is divided into heavier and thicker, on the one hand, and lighter, on the other. Accordingly, each of these varieties has its own gluing features and inherent performance characteristics.
Such types of wallpaper as vinyl are quite heavy, so gluing them, firstly, is not so easy, and secondly, the process itself takes quite a lot of time. On the other hand, they have a number of significant advantages. One of them is that they do not shrink after the glue dries. This helps avoid the formation of tears at the seams. By using vinyl sheets, you no longer have to figure out how to hide the separated joints.
Know! In order to prevent the seams between the wallpaper from coming apart, experts advise using a special small roller. With its help, the junction of the sheets is ironed additionally after gluing.
Roller for smoothing joints
As for gluing non-woven wallpaper, you need to buy special kind glue. At the same time, a pleasant “bonus” when carrying out the work will be that when gluing them, it is enough to apply a layer of glue only to the sheet itself, without coating the wall. By the way, this type of wallpaper is often glued before painting.
As for paper wallpaper, gluing it is not so easy. Everything is explained by their thinness and susceptibility to getting wet by glue. In such cases, it is important not to overdo it with the amount of adhesive solution applied, because if there is an excess of it, when it dries paper wallpaper may shrink. Unraveling seams, which are so unpleasant for the eyes, will appear in these places.
As doctors say, prevention is better than cure. The same is true here: it is much easier to hang wallpaper correctly by properly dosing the glue, and also using a roller to smooth the joints. In this case, before rolling with a roller, it is recommended to wet wallpaper fabrics at joints.
Regardless of whether your canvases are light or dark, whether you are gluing walls or ceilings, strictly follow the manufacturers’ instructions, as well as the advice of experienced specialists. And then such problems will bypass you.

Instructions
The reasons why seams on the wallpaper may be visible can be different. The first is that the canvases have moved away from each other, this happens if the wallpaper changed its size when hung, and after drying it returned to its original shape. The glue got on the front side of the canvas - and therefore the seam came apart. The edges of the wallpaper have unpainted ends. Nowadays, wallpaper is mainly sold that is glued end-to-end, and not overlapping as before. After gluing such wallpaper, the seams are invisible. If you have chosen wallpaper with a pattern, then when hanging such wallpaper you will need to select it.
To hang any wallpaper without a flaw, you need to prepare the surface. The walls must be smooth, primed and dry at the time of gluing. If you are gluing vinyl wallpaper, please note that they are divided into light and heavy. Heavy wallpaper will help hide minor unevenness in the walls, but gluing them will take more glue and time. Before gluing, coat all types of vinyl wallpaper with glue and leave to soak for a while. The wall is also coated with glue. The gluing of such wallpaper begins from top to bottom, and from the side front door. Using a dry roller or a special spatula, smooth the wallpaper so that there is no air left under it. Vinyl wallpaper does not change its shape, and therefore, after drying, the joints become almost invisible. To be on the safe side, you can use a special glue for joints; it is sold in tubes with sharp noses for easier application. It is applied when 2 sheets are glued - additionally between the joints, and then the seam is passed with a roller.
Non-woven wallpaper is glued according to a slightly different principle. They require special glue, and, like vinyl wallpaper, Smooth surface. The glue is applied only to the wall, and the wallpaper itself remains dry, since if you apply glue to the wallpaper, after drying it will narrow and cracks will form. Such wallpaper can be glued before painting, after which the seams will not be visible at all.
The most difficult part is gluing paper wallpaper. Before pasting, such wallpaper needs to be soaked a little, that is, coated with glue and allowed to soak in the glue a little. The wall also needs to be coated with glue. The peculiarity of paper wallpaper is that when it gets wet, it loses its shape, and when it dries on the wall, unraveling seams can form. You can paste such wallpaper overlapping, and after drying there will be no discrepancies in the joints, but there is a possibility that joints in the form of tubercles will remain. You can also use special joining paper. It is glued between the canvases at the junction of the wallpaper, but it does not guarantee one hundred percent that the joints will not separate when the wallpaper dries. Last option paint the joints with paint to match the wallpaper; after drying, even if the seams come apart, it will not be so noticeable visually. The last method is used mainly by beginners.
Well, the rough preparation of the walls has been completed and it’s time for the most interesting stage - wallpapering. In order to admire a beautiful wall covering without visible joints, you need to make a lot of effort. It is not necessary to glue the wallpaper overlapping; there is another option. You can even do this yourself, without the help of professionals, if, of course, you know the technology. This article will tell you and teach you how to glue wallpaper end-to-end correctly, and you can clearly see the process itself in the videos contained.
If the procedure of wallpapering a room is performed for the first time, there is a suspicion that it will take a long time. In order not to be distracted during the process by searching for everything you need, it would be correct to prepare all the tools and materials in advance. First of all, of course, you will need the wallpaper itself and wallpaper glue. You will also need:
It is important to note that the glue must be selected in accordance with the type of wallpaper. Each pack of dry adhesive powder indicates what wallpaper it is intended for. Also, when choosing, you can consult with the seller, who will help you choose the adhesive powder correctly.
As a rule, people who carry out repairs on their own do not have the same skills as professionals, so before hanging wallpaper, you must definitely cut it into sheets of suitable length. Professionals, as a rule, glue canvases directly from the roll, without cutting them, regardless of whether they are end-to-end or overlapping. This preparation is especially important if the wallpaper has a pattern or relief that needs to be adjusted.
To correctly cut panels with a pattern, you need to find a repeat pattern on the packaging, which determines the length through which the pattern is repeated. This indicator helps to use wallpaper more economically and correctly than with conventional measurement and calculation. You can make markings using a repeat in this way: for example, the value is 60 cm, and the height of the ceilings in the room being renovated is 2 m 80 cm. In this case, there will be 4 repeats per roll, which we multiply by its value, that is, by 60 cm The result is 240, this is not enough, since the panels turn out to be shorter than the height of the ceiling. We take 5 repeats and multiply by 60 cm, it comes out to 300 cm. This number is just right. It is necessary to cut all the rolls into equal parts of 300 cm. What remains does not need to be thrown away, it can be glued in small places, for example, under the windowsill or behind the radiator.
After the panels of the required length are prepared, it is necessary to mark the walls. This is also very important stage, the passage of which eliminates oblique gluing and allows you to do everything correctly. For marking, you will need a plumb line, with which vertical lines are measured and drawn along the entire surface of the walls at a distance equal to the width of the roll. You can do this starting from anywhere in the room, but not from the corner. This process is shown in the video.
There are only two ways to hang wallpaper: overlap and butt. Only very thin paper wallpapers are glued with an overlap or processing is done in the corners. This method takes a large number of material, and, as a rule, overlapped sheets stand out too much at the joints. Therefore, it is preferable to choose the second method.
To create a beautiful decorative wallpaper covering as a result, we follow this scheme:
To properly wallpaper walls butt-to-end, you need to take into account external factors. This is the air temperature in the room, which should be no more than 20 degrees. It is also necessary to close the windows and doors in the room so that drafts do not interfere with the drying of the glued canvases. Direct Sun rays also do not have a very favorable effect on freshly hung wallpaper.
As soon as a straight wall is glued, the question always arises of how to design the corner. Typically, apartments do not have perfectly even corners, which is why the problem of bubbles arises. You can solve this; there are two ways to do this:
In the following video you can see how this is done clearly.
