How to glue wallpaper in corners - the secret to perfect gluing. How to beautifully join different types of wallpaper in the corners, especially if they are uneven. How to stick wallpaper on the corner of a wall

Nowadays non-woven wallpaper or wallpaper based on it is becoming more and more popular, and this is not at all surprising. They are distinguished by durability, ease of maintenance, and soundproofing qualities. In addition, recently manufacturers have been producing wallpaper twice as wide as a regular roll, 1 meter and several centimeters wide. Thus, gluing can be done several times faster, and there are fewer joints.

But many are afraid to purchase non-woven wallpaper because they are worried that they will not be able to stick it correctly, especially in the corners. Such worries are absolutely groundless, because in order to cover corners efficiently and beautifully, it is enough to know simple rules. Let's look at this topic in more detail.

What is non-woven wallpaper

In fact, this is wallpaper that is made of foamed vinyl, and the base is non-woven material. This lining material is based on cellulose fibers, which should be at least 70% of the composition. Their main advantage is that they visually level out all the unevenness of the wall, making it perfectly smooth. Also, vinyl wallpaper on a non-woven backing insulates the room from extraneous sounds: the knocking and screams of neighbors behind the wall will become less noticeable.

Non-woven wallpaper or vinyl wallpaper on a non-woven basis can be painted several times and even washed with a sponge to remove dirt. And when you decide to make repairs and peel off the wallpaper, only the top layer is removed, and the non-woven layer will serve as the basis for gluing new ones.

Non-woven wallpaper is very practical; you don’t need any special skills to glue it. But there are a few tips that will undoubtedly be useful to owners who decide to do the repairs themselves.

You can clearly see how to glue non-woven wallpaper in the video:

Gluing internal corners

Remember, the main rule for pasting corners is not to do it with one piece, so that one part of the solid strip is on one wall, and the second on the other. In this case, non-woven wallpaper may stretch, and the result will definitely not hit you. This rule applies to both internal and external corners. The correct solution would be to cover each wall with a separate piece, which simply fit together correctly.

To glue correctly, there are several ways that will undoubtedly lead you to the expected result.

Option 1. One of the simplest methods is to overlap the wallpaper in the corner. Thus, one sheet is glued with a spacing of 1-1.5 cm, and the second exactly along the corner line, i.e. There is no gap between the wallpaper, and the angle is neat and visually even.

Attention! Non-woven wallpaper is quite dense and thick, so the cut will still be visible.

Option 2. This method is most often used in rooms where the walls are not quite right and are a little overwhelmed. The first sheet is pasted with an allowance on the adjacent wall, so as to cover the entire corner. The width of the overlap depends on how uneven the walls in the room are. The second one is also glued with an overlap, so that the design is not distorted or displaced. After this, use a level or any other flat object to press a clear line, and use a sharp stationery knife to make a precise cut. Then easily remove the top excess strip.

The bottom part will be more difficult to remove, but just peel back the glued top part and you'll be good to go. After this, reapply glue to the edges and carefully attach them in place. The whole procedure should be carried out as quickly as possible, and then you will get the perfect angle even on such uneven walls.

Option 3. One strip is glued to the wall with an overlap of about 2 cm. Then, using a plastic spatula, it is carefully driven into the depths of the corner. All folds and irregularities can be eliminated quite simply: you need to make several cuts and overlaps, thus eliminating the unevenness of the canvas and the wall.

Next, take a long metal spatula, press it tightly to the corner and carefully cut off the excess material in one motion. The second strip is glued in the same way and cut. If everything is done correctly and carefully, you will get a monolithic seam that will be almost invisible to prying eyes.

Some options can be seen visually here:

External corners

In addition to internal corners, any room also has external ones. Often these are window slopes or niches and protrusions that cannot be ignored. They have their own characteristics of pasting. With the help of small secrets, gluing will become easy, and the corners will be neat and beautiful. The algorithm for pasting external corners is as follows:

In the end, I would like to say that non-woven wallpaper, even on a non-woven base, is a fairly dense and practical material that is very easy to glue. It cleans well and will please the eyes of its owners for a long time.

Wall decoration is an integral part of apartment renovation. Of the many options, probably the most famous and popular material for wall decoration is wallpaper. A huge selection of textures and patterns, an affordable price and an excellent ability to radically refresh a room - these are the main advantages of this material, which have captivated owners of apartments and houses for decades.

Another advantage of choosing wallpaper is the ability to do simple work yourself, saving money and enjoying the result. However, the surface of the walls is uneven and many are stopped by the question: how to glue wallpaper in the corners?

Pasted canvases repeat the unevenness of the walls, hiding some of them. But on the corners it happens differently. Even non-woven wallpaper, which easily stretches like fabric, wrinkles when drying at uneven corners, folds and distortions appear. Later they come off in these places. To prevent this from happening, you should know how to glue them correctly.

Preparing wall corners

Save

Even if the walls are plastered according to the beacons and well-puttyed, this does not mean that everything is in order with the corners. Small recesses and grooves are unacceptable; they are filled with putty. Ideally, when puttying and subsequent sanding, the inner corner is given a minimum radius of curvature.

This will allow you to completely remove excess glue and air when gluing. When preparing an external corner, it is necessary to use a perforated corner. This will help create straight lines and properly wallpaper, and will protect the plaster from collapsing during light impacts, which happen, for example, when furniture is moved.

When applying primer to walls, use a roller. Use a brush to thoroughly prime the corners. Choose the order in which you will paste the sheets and decide where to start. It may be more convenient to start at the edge of the window or door opening. To start, choose a wall with a less noticeable corner, such as where a cabinet will sit.

Take in your hands a narrow strip of wallpaper, cut to width from a roll. Walk with it along the selected wall, trying out options for the arrangement of sheets. When choosing an option for how to properly wallpaper corners, strictly follow the rules:

• sheet joints in the corners are unacceptable;
• no matter how smooth the corner may seem, do not plan to cover it with a single sheet;
• Instead of an overlapped sticker, use an overlapped sticker followed by a double cut.

Shifting the starting point, select such a location on the wall for the first panel so that approximately the middle part of the next panel falls on the corner walls. Using a plumb line and a sharp pencil, mark a vertical line on the wall. It is not necessary to draw a solid line, which may later become noticeable.

You can make barely noticeable centimeter-long marks every 20–30 cm and draw a line not from the very joint, but, say, one centimeter to the left or right, so that this line is subsequently closed. Such an inconspicuous line will serve as a reliable guide and will not appear later at the junction itself, as sometimes happens.

Gluing the first panels

Let's remember the sticker sequence:

• Open the wallpaper with or without a selection of patterns (according to the instructions on the roll).
• Apply glue to the walls, canvas or walls and canvas (according to the instructions).
• If the canvas is glued, fold it so that the glue does not dry out prematurely.
• Glue the canvas on the wall from the ceiling down, aligning with the vertical mark or with the extreme edge of the already pasted canvas, aligning the pattern.
• Carefully remove any remaining air with a roller or brush, smoothing from the center to the edges.
• Using a wide spatula and a utility knife, trim the top and bottom of the panel, smooth it again with a roller, apply glue if necessary, and smooth it again.

How to wallpaper: inner corners

1. We cut out a strip from a single piece of cloth, 5 centimeters wide greater than the distance from the last piece to the corner (we measure at the ceiling, in the middle and at the floor, take the largest), the remaining piece will be glued after the first.
2. We coat it with glue (according to the instructions for the wallpaper) and stick the prepared canvas, smoothing it with a roller or brush, first on the wall, then in the corner and then a strip on the next wall, removing excess glue and air.
3. In places where the wallpaper wrinkles noticeably, we make horizontal cuts 5–10 cm apart.
4. Using a plumb line, we draw a vertical line for gluing the remaining piece of canvas so that it overlaps 2 cm onto the previous canvas in its narrowest part.
5. We coat and glue the remaining canvas, aligning the smooth edge with the applied vertical line, smoothing to remove any remaining glue and air.
6. We prepare the knife; to do this, before each cut, we break off the tip of the knife according to the marks on the blade.
7. Using a knife and a wide spatula, we cut without tearing, in one step, both layers of the canvas so that the cut passes a centimeter from the edge of the second strip.
8. We remove the cut excess, if necessary, bend the edges and add glue, roll it with a roller.

After double trimming, an invisible joint remains. If you don't succeed the first time, remove the pasted strips and repeat with great diligence. It will definitely work out, and you will know how to properly hang wallpaper in the corners.

Pasting the external corners of the room is carried out in the same order and in compliance with the same rules: we carry out the markings so that there are no joints and do not try to paste them with a solid canvas.

After gluing the first corner piece of canvas, the wrapped part of the wallpaper should be at least 5 cm. Apply glue to the next canvas according to the markings so that the overlap in the narrowest part is at least 2 centimeters. Save

Useful advice from experts

• If you find an air bubble and it does not smooth out, pierce it, remove the air, pour in a little glue with a syringe and smooth it with a roller.
• Sometimes when trimming from above, below or at the window and doorway, the wallpaper gets chewed. Let them dry a little and repeat the cutting. Perhaps the knife has become dull and it's time to change the blade.
• Do not allow drafts in the room, this can lead to premature uneven drying and peeling of the canvases.
• De-energize the sockets and switches in the room in advance and remove their frames. You can return it to its place immediately after pasting.
• When gluing to problem areas, add 10% PVA glue to water when preparing the glue.
• If old wallpaper is difficult to remove, wet it with primer using a paint roller. Remove immediately before the primer dries.

Gluing modern wallpaper is not a difficult task. Even a novice repairman can handle this. But, if installing canvases on smooth walls is easy and simple, then you will have to tinker with the corners. It is the corners that become the stumbling block that slows down the entire process and requires a lot of effort. More often than others, non-woven wallpaper or vinyl sheets on a non-woven basis are used in repairs.

Features of the material

Wallpaper consisting entirely of non-woven fabric is easy to install and durable. They are made of non-woven cellulose with the addition of synthetic components. The cellulose component gives the wallpaper elasticity and breathability, while synthetics add strength. Such wallpaper is much more difficult to tear than paper-based vinyl, for example. In addition, they do not wrinkle at all and there are no folds left on the surface.

Non-woven vinyl wallpaper has the same properties. The only difference is that the canvases do not “breathe”, since vinyl does not allow air to pass through. Therefore, before gluing them to the walls, it is necessary to treat the surfaces with antibacterial primer or use glue with fungicidal additives. These measures will prevent the appearance of mold and mildew.

Non-woven wallpaper has a number of advantages over other coatings:

1. Their feature is good adhesion to glue and to any wall material. Such canvases do not need to be treated with an adhesive; it is applied only to the walls. The same applies to non-woven vinyl.
2. A useful quality of non-woven fabric is its tensile strength. The material does not shrink after the glue dries, and the dimensions of the canvas do not change. Thanks to this, the joints do not diverge, and the seams between the strips remain invisible. This feature is especially useful for wallpaper intended for painting, since painting makes all wall defects even more noticeable.
3. Non-woven fabric cannot be washed, but can be dyed. But cellulose-based vinyl can even be cleaned with detergents, and it is also easy to paint.
4. Due to the bulk of cellulose fibers, such wallpapers level the walls and hide small unevenness. Durable synthetic components are resistant to tearing, which allows non-woven wallpaper to reinforce walls. They prevent cracking by holding the plaster in place.
5. Non-woven wallpaper is easy to remove; its two-layer nature allows you to leave the backing on the surface and use it as a base for new coatings.

Installation of wallpaper on walls

There are several ways to glue wallpaper (you can easily see them from photos or videos). One of them involves initially gluing all smooth walls, and then the corners. Other artists advise starting from the most visible corner in the room. There is no consensus on this issue - everyone can glue at their own discretion.

Wall preparation is mandatory for any method. The old coating must be carefully removed and cracks filled with putty. Then the walls are covered with a special primer or wallpaper glue. Only after the primers have completely dried do they proceed to pasting the walls.

At the location of the reference point, draw a vertical line; this must be done with a plumb line or a building level. The first strip is cut from the roll, the length of which is equal to the height of the wall plus 5-7 cm. The wall is carefully coated with glue and wallpaper is applied. Level the canvas with a plastic spatula or wallpaper roller, focusing on the vertical.

Advice! It is better to use a special glue with a color indicator - in liquid form this composition has a pink tint, and after drying it becomes colorless. This allows the adhesive to be applied evenly to the wall without leaving any “gaps.”

At the baseboard and under the ceiling, the wallpaper is cut with sharp scissors or a construction knife. Move on to the next lane.

How to glue wallpaper in corners

In order to properly cover corners, you first need to understand their types. The angles are:

• Internal - each room has at least several such corners (in the standard layout there are four). A very important factor is the correctness of these areas. If the angle is uneven, has differences, or “sinks,” the wallpapering method will differ from the standard one.
• External corners in apartments began to appear more often with the advent of drywall - these are a variety of niches, arches, columns and other decorative elements. This also includes door and window slopes, if, of course, it is planned to install wallpaper in these areas.

Easy way

It is easiest to paste over a completely flat corner. Unfortunately, these are quite rare. These are either plasterboard structures or walls prepared for painting (plastered perfectly smooth and even).

In this case, the wallpaper is glued in the same way both in the inner and outer corners - they are simply wrapped in a single piece of wallpaper. The main thing is not to stretch the coating; after drying, it can return to its original size and shape. If there are small wrinkles on the wallpaper, you can make several horizontal cuts in the corner. This will help to even out the coating, and the cuts will not be noticeable after drying.

Important! No matter how smooth the corner is, it is better not to use the method of covering it with a solid canvas if it is connected to an external wall. In corners located near external walls, condensation appears more often - the wallpaper can peel off and become deformed.

Standard method for gluing corners

It is safer to glue wallpaper in the corners using the “overlapping” method. Its essence is as follows:

1. After pasting the adjacent wall, measure the distance to the corner at three points.
2. Based on the largest of the three values ​​obtained, the strip is cut off - its width is equal to the largest number plus 2-3 cm for overlap.
3. The wall is coated well with glue, especially paying attention to the corner (it is better to use a brush).
4. The prepared piece of wallpaper is applied to the corner, aligning the joint with the previous sheet.
5. The overlap formed on the adjacent wall is carefully pressed, tucking the wallpaper into the corner with a plastic spatula.
6. For a tighter fit, the edge of the wallpaper can be trimmed - make short horizontal cuts every 5 cm.
7. Trim the bottom and top edges of the wallpaper using a metal spatula and a sharp knife.
8. From the narrowest point of the overlap, retreat about one centimeter towards the corner and make a mark.
9. Focusing on the mark, draw a vertical line in this place using a plumb line or level.
10. Prepare the next strip (if necessary, select a pattern).
11. A strip is applied to the wall coated with glue, aligning its edge with the previously drawn line in the corner.
12. Level the strip, expelling air and excess glue. Cut under the ceiling and near the floor.

Corner processed! They move on to gluing a flat wall to the next corner - repeat the procedure. In this way you can glue external corners with different types of wallpaper.

Advice! Considering the considerable thickness of non-woven wallpaper, the overlap may be too noticeable.

In this way, you can paste over those corners that will be hidden by furniture or curtains, and choose another method for finishing the rest. You can also try cutting off only the top layer of wallpaper.

It is not necessary to glue the slopes with wallpaper; the video shows how they can be beautifully trimmed at the corners:

Corner cutting method

If the walls are to be painted, there should be no overlaps on them. Paint will make the thickening of the wallpaper too noticeable; another method will be needed here. This method is suitable for both internal and external corners.

The work is performed in the following sequence:

1. Repeat the first seven points from the previous instructions - the strip is glued with an overlap to the next wall. Only in this case the overlap is made larger - 5-7 cm.
2. A distance equal to the width of the roll minus one centimeter is retreated from the corner.
3. Using a plumb line or level, draw a vertical line at this point.
4. Cut a strip from the roll and apply it to the wall coated with glue, aligning the edge with the drawn strip.
5. The second edge is placed on the previous strip with an overlap, the wallpaper is pressed and leveled.
6. Carefully push the wallpaper into the corner with a spatula, leveling everything again.
7. In the middle of the overlap, apply a metal ruler vertically, take a very sharp knife and, without breaking it, draw a line along the edge of the ruler. It is very important that the line is drawn in one motion.
8. Remove a piece of the upper fabric, bend the edge of the lower one and also remove the excess.
9. Both edges are coated with glue and folded end to end. You can slightly pull the canvas in the right direction so that there is no gap or overlap.
10. Roll with a roller for joints.

This method helps to make the connection of the canvases invisible. It also works well on external corners, in niches and on slopes.

Advice! It is better to use a small metal spatula 10-15 cm instead of a ruler

Due to the unevenness of the corners, the ruler may not fit tightly to the wall, and the cut will turn out crooked. The spatula must be moved along with the knife, avoiding breaks in the cutting line. How to properly trim wallpaper in the corners can be seen in the video:

When renovating an apartment with your own hands, decorating walls with wallpaper is the simplest type of work. Minor difficulties arise only when gluing hard-to-reach places: radiator, window, door and corner. But if you know simple techniques, then everything here can be done quickly and with high quality. At the same time, the greatest number of secrets lies in the technology of pasting the corner. After all, it can be external and internal - hence the different solutions. To help novice decorators, in this article we will look in detail at how to properly glue wallpaper in the corners.

To glue wallpaper in the corners, you will additionally need the following materials and tools (the basic materials and tools for decorating walls with trellises are listed in the work “”):

• gypsum putty;
• corner spatula;
• metal profile for a lighthouse (any) 2.5 m long;
• a grinder or a hacksaw for cutting the profile to the height of the wall to be pasted;
• hammer drill for installing dowels;
• dowels with self-tapping screws;
• Phillips screwdriver or screwdriver.

Preparing corners

When wallpapering corners, it is difficult to ensure that they fit tightly to adjacent walls without folds, air pockets and excessive tension. The joints of adjacent walls are to blame for this. They are either uneven, zigzag-shaped if the walls are plastered, or filled up if the house is panel.

Therefore, an important task is to align the corners before starting work on decorating the room with wallpaper. Professional builders have several methods for this. The most common ones are listed below.

Method No. 1. One of the walls is strictly vertical, control is carried out with a plumb line, a rule is applied closely, or even better - a metal profile. Thus, the most protruding point of the surface of the adjacent wall is located.

An angled spatula is applied closely to the point, and a profile is applied to the spatula. Again, using a plumb line, the profile is brought into a strictly vertical position, after which 3-4 marks are made on the wall for installing dowels. Holes for them are drilled using a hammer drill, after which the profile is attached to the wall with self-tapping screws.

The corner is wetted with water, after which gypsum putty is applied to it. Using an angle spatula, pressing against the profile, a perfectly even angle is formed. Excess plaster is removed and the procedure is repeated at the next corner.

After the putty has dried, it is processed with zero-grade sandpaper.

Method No. 2. For this method, you will need a counter-shultz (plaster corner), which is a metal or plastic corner with a mesh attached to the edges.

It is installed in a corner strictly vertically (a plumb bob or a laser level will help) and attached to the wall with putty applied over a mesh. After complete drying, the putty layer is sanded with a special mesh or sandpaper.

The above methods for leveling corners allow you to solve any violations of the geometry of the joints of adjacent walls.

How to tape corners

When working with wallpaper, novice decorators will definitely encounter pasting internal corners and, possibly, external ones. The methods for gluing them are different, regardless of whether paper, vinyl or non-woven trellises are used.

Attention: in this section we are talking about plain wallpaper that does not require color adjustment. We will talk about how to stick wallpaper in the corners of a room with a pattern at the end of the work.

So, how to wallpaper in the corners?

External

In apartments of modern construction there are practically no external corners that need to be covered. An exception is window slopes, but they are usually painted rather than glued. If you still have to glue the outer corner, then below we will provide instructions on how to glue wallpaper in the corners of the room in this case.

The step-by-step algorithm of actions is as follows:

1. We measure the width of the sheet to be glued so that it goes around the corner by only 3-5 cm and cut it with scissors (a construction knife);
2. Spread the trellis with wallpaper glue and let it soak for 5-10 minutes;
3. We glue the wallpaper to the wall using standard technology;
4. After excess glue and air bubbles have been removed from under the main sheet, wrap its strip on the other side of the corner and glue it. If problems arise: folds form or the canvas cannot completely stick to the wall, we make cuts in problem areas;
5. Stepping back from the edge of the corner by 5-7 mm, using a plumb line and a pencil, draw a vertical line;
6. We prepare the following sheet for gluing: cut it to size in length and width if it is a window slope, or take a whole sheet of wallpaper if the work continues on the wall, spread it with glue and give time for the base of the mites to soak in the mixture;
7. We glue the sheet overlapping onto the strip of wallpaper strictly along a vertical line so that subsequent sheets are glued evenly;
8. If the seam is noticeable, then using a long metal ruler, or better yet a profile for beacons, cut both sheets of wallpaper with one knife cut;
9. Remove the cut strips;
10. We process the resulting joint with a narrow roller until the seam is closed.

Domestic

When pasting the inner corner, the last strip of wallpaper should cover the adjacent wall by 2-3 cm. To do this, it is adjusted to the width - it is measured, and the excess part is cut off. After gluing it, a vertical is drawn on the strip to the wall at a distance of 4-5 mm from the corner.

To do this, use a plumb line and a pencil. The next wallpaper sheet is glued overlapping, strictly along a vertical line. If the seam is barely visible, this completes the gluing of the corner. Otherwise, a cut is made to remove the parts of the wallpaper glued to each other and form a butt seam.

Note that the use of wide, meter-long wallpaper reduces the number of seams, which speeds up the entire technological process, but greatly complicates work in the corners.

How to match wallpaper with a pattern

With a relatively small collapse of the wall, a deviation from the vertical of up to 2 cm, it is possible to join wallpaper with a clear geometric pattern so that the location of the seam can only be detected as a result of a careful examination of the wallpapered wall.

Let us immediately note that a shift in the pattern is possible, but very slight, and therefore hardly noticeable if everything is done in accordance with the instructions.

1. Take a cut sheet of trellis, matched according to the pattern with the last wallpaper pasted, and spread it on the floor face up.
2. Using a tape measure, measure the distance from the edge of the last sheet to the corner at the top and bottom of the wall. For example, at the top the width of the unpasted space will be 23 cm, at the bottom - 21 cm.
3. We transfer the obtained measurement results to a spread sheet of wallpaper. We mark the control points with a pencil or cut them a little with scissors. The main thing here is not to confuse the top with the bottom.
4. Add another 5-6 cm to 23 cm and cut a piece of wallpaper 28-29 cm wide.
5. We put a whole tapestry of tapestry on the cut sheet and join it according to the pattern so that the 21 cm point overlaps (exactly this point, otherwise nothing will work).
6. We cut the wallpaper to length and cut out the part that overlaps the mark (it is not necessary to cut it; you don’t have to coat it with glue, which is a little more difficult).
7. Turn over the first sheet and spread it with wallpaper glue.
8. We glue the sheet onto the wall end-to-end with the last piece, carefully working first the seam and then the corner. The last thing to do is glue the overlap. In this case, the formation of folds should not be allowed.
9. We retreat from the corner by the width of the next sheet of wallpaper and draw several vertical lines with a pencil along a plumb line at a distance of 0.5 cm from each other.
10. Apply glue to the next sheet of wallpaper and fold it so that the wallpaper is saturated with the mite mass.
11. After impregnation of the sheet, open the top and glue the canvas so that the pattern in the center of the wall matches perfectly. Focusing on the vertical lines, we glue the wallpaper along the entire length on the side farthest from the corner. Smoothing must be done towards the corner.
12. Using a metal profile and a construction knife, we cut both sheets of wallpaper at the same time (the cut should go along the overlapped trellises).
13. We remove the cut strips of the bottom and top sheets.
14. Using a narrow roller we process the resulting joint.

For reference: there is no need to match wallpapers with different patterns. They are glued according to a simplified scheme.

There is nothing complicated in the materials answering the question of how to properly glue wallpaper in the corners of a room. The work can be easily done by yourself.

Other nuances of pasting corners

Every master in any field of activity always has his own little secrets. Wallpapering corners is no exception. It also has its own secrets.

• If the wall deviates significantly from the vertical, more than 2 cm, you should buy wallpaper without a pattern or with a pattern that does not require careful adjustment - a crooked angle will skew the pattern and ruin the effect of the repair.
• The corners must be primed to enhance the adhesion of the wallpaper glue to the wall - the lag of the trellises usually begins in the corners. If the primer was not applied over the entire surface of the walls, then instead of primer in the corners, you can use water-based paint or wallpaper glue, which is spread 4-5 hours before starting work.
• Glue in the corners must be applied only with a brush - the roller allows gaps (does not cover the entire surface), which will negatively affect the quality of the pasting.
• Before gluing the main panel, it is advisable to glue the corner with a strip of wallpaper 10 cm wide (the recommendation applies to smooth wallpaper). This will hide the unraveling seam and strengthen the trellises from tearing. Professionals often use Cobweb painting fiberglass instead of a paper strip.
• For heavy or thick wallpaper in the corners, you must use a special transparent adhesive.
• Non-woven wallpaper most effectively hides uneven corners.
• When folds form, while smoothing out a strip of wallpaper that has reached the other side of the wall, the spade needs to be trimmed in a herringbone pattern, which will allow it to be leveled. The next sheet glued overlapping will hide the cuts made.
• Ironing the trellises in the corners is carried out until the air cavities disappear - the sheet of wallpaper should fit snugly against the wall and not hang in the air.
• After removing the scraps formed after cutting the seam, the edges of the sheets are carefully moved away from the wall with a metal spatula and coated with glue. If this is not done, the edge of the wallpaper under which the cut strip was located will definitely fall behind - almost all the adhesive mass is removed with the strip.
