How to properly glue wallpaper in the corners of a room?

Although handling corners can frequently be a little challenging, adhering wallpaper can be a rewarding way to update the appearance of any space. It can be difficult to get the wallpaper to lie flat in these places without wrinkling or bubbling. However, you can accomplish a professional finish with the appropriate strategy and close attention to detail.

Having a spotless, even surface is crucial when working on corners. A less-than-perfect outcome could result from the wallpaper misaligning due to any lumps or flaws in the wall. Before you start, make sure to fill in any holes and smooth down any uneven areas.

Avoiding trying to wrap a single piece of wallpaper around a corner is one important piece of advice. The paper may stretch and tear as a result of this. Rather, trim the wallpaper to end just before the corner, then begin the new piece by slightly overlying the old one. This technique improves wallpaper adhesion and guarantees a seamless appearance.

To ensure a tight bond to the wall and lessen the chance of air bubbles, you can press the wallpaper firmly into the corner with the aid of a wallpaper smoothing tool. Here, accuracy and patience are your greatest friends. Take your time, smoothing out each section as you go.

Your wallpapered room’s overall look can be significantly improved by following these easy steps. Beautiful, crisp corners that improve the appearance of your space can be achieved with meticulous planning and a methodical approach.

Materials and tools

You will also require the following supplies and equipment to glue wallpaper to the corners (the essential supplies and equipment for adorning walls with trellises are detailed in the article "How to properly hang wallpaper with your own hands"):

• 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

It can be challenging to wallpaper corners so they fit tightly against neighboring walls without creasing, creating air pockets, or requiring too much tension. This is due to the joints between nearby walls. If the walls are plastered, they are either uneven, zigzag-shaped, or scattered if the home is paneled.

Thus, before beginning to decorate the room with wallpaper, it is crucial to align the corners. Expert builders use a variety of techniques to accomplish this. These are a list of the most popular ones.

Method No. 1: Strictly vertical control is applied to one wall using a plumb line, a rule, or, for best results, a metal profile. As a result, this is where the adjacent wall’s surface most prominently projects.

The point is carefully worked with an angled spatula, and the spatula is then coated with a profile. Once more, the profile is brought into a strictly vertical position using a plumb line. Following this, three to four marks are made on the wall for the dowel installation. Using a hammer drill, holes are drilled for them, and then self-tapping screws are used to secure the profile to the wall.

Water is sprayed onto the corner, and then gypsum putty is applied. A perfectly even angle is formed by pressing against the profile with an angle spatula. After removing any extra plaster, the process is carried out at the next corner.

Zero-grade sandpaper is used to process the putty once it has dried.

Method No. 2 requires the use of a counter-shultz, also known as a plastic or metal corner with mesh fastened to the edges.

It is put in a corner, strictly vertically (a plumb bob or laser level will help), and putty is used over mesh to attach it to the wall. The putty layer is sanded using sandpaper or a specific mesh once it has completely dried.

You can solve any violations of the geometry of the joints of adjacent walls by using the corner alignment techniques mentioned above.

Although adhering wallpaper to a room’s corners can be challenging, done correctly, the effect can be smooth and expert. To ensure you have some extra wallpaper, measure and cut the strips a little longer than what is required at first. For a strong hold, apply adhesive to the wallpaper’s back as well as the wall. Using a brush or roller, evenly apply the wallpaper into the corner, being careful not to leave any wrinkles or bubbles. With a sharp knife, carefully trim off any excess, then firmly press the edges down using a seam roller. Your corners will appear perfect if you are patient and pay close attention to detail.

How to tape corners

Inexperienced finishers will undoubtedly run into pasting internal and possibly external corners when working with wallpaper. Whether you use non-woven trellises, paper, or vinyl, the techniques for adhering them are different.

Note that we are discussing plain wallpaper in this section, which doesn’t require color correction. When all is said and done, we’ll discuss how to apply wallpaper with pattern in a room’s corners.

So, how should the corners be wallpapered?

External

Modern apartment buildings essentially lack exterior corners that require covering. Window slopes are an exception, but they are typically painted rather than glued. In the event that you still need to glue the outer corner, we’ve included instructions below on how to glue wallpaper in the room’s corners.

The following is the step-by-step action algorithm:

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. Retreating from the edge of the corner by 5-7 mm, using a plumb line and pencil, we apply a vertical line;
6. We prepare for gluing the following sheet: cut into size in length and width, if it is a slope of the window, or take a whole canvas of the wallpaper, if the work continues along the wall, spread glue and give time to impregnate the base of ticks with mass;
7. We glue the sheet overlap on a strip of wallpaper strictly along the vertical line so that the subsequent sheets are glued evenly;
8. If the seam is noticeable, then with the help of a long metal ruler, and preferably a profile for lighthouses, we cut both sheets of wallpapers with one knife carrier;
9. Remove cut strips;
10. The formed joint is treated with a narrow roller until the seam is closed.

Internal

The final wallpaper strip should overlap the neighboring wall by two to three centimeters when pasting the inner corner. In order to accomplish this, the width is adjusted, measured, and the excess portion is chopped off. Following the glue, a vertical line is drawn on the strip that is spaced 4-5 mm from the wall to the corner.

Pencil and plumb line are used for this. The adhesion of the subsequent wallpaper sheet is done strictly along the vertical line, with an overlap. This finishes pasting the corner if the seam is not very visible. If not, a cut is made to enable you to separate the wallpaper’s adhesive sections and create a butt seam.

It should be noted that while using wide, meter-long wallpaper minimizes seams and speeds up the entire technological process, it makes the work in the corners much more difficult.

How to join wallpaper with a pattern

It is possible to join wallpaper strips with a distinct geometric pattern with a comparatively small wall tilt—a departure from the vertical of up to 2 cm—so that the seam can only be detected through closely inspected pasted walls.

Let us acknowledge right away that, provided all is followed to the letter, a shift in the pattern may occur, but it will be very slight and thus barely perceptible.

1. Take a cut sheet of trellis, matched according to the pattern with the last pasted wallpaper, 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 onto 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 place 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, spread it with wallpaper glue.
8. We glue the sheet onto the wall end-to-end with the last sheet, carefully working out the seam first, and then the corner. The last thing to do is to glue the overlap. In this case, the formation of folds should not be allowed.
9. We retreat from the corner to 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 vertical lines, 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. Use a narrow roller to process the resulting joint.

As an example, wallpapers with disparate patterns don’t have to be combined. They are adhered to using a rudimentary layout.

The answer to the question of how to correctly glue wallpaper in a room’s corners is not difficult to find in the materials. You can complete the task on your own with ease.

Other nuances of pasting corners

Every expert in any field has a few little secrets of their own. Corners with wallpaper are not an exception. It has secrets of its own as well.

• 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 distort the pattern and spoil 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 coat 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 must 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.

While adhering wallpaper to a room’s corners may appear difficult, it is manageable with the correct technique. The preparation and method you employ are crucial. To achieve a perfect finish, you must first make sure the walls are clean, dry, and even. To guarantee a seamless appearance, precisely measure and cut your wallpaper, allowing for some overlap in the corners.

When applying the wallpaper, begin hanging it from the top and use a wallpaper brush or smoother to smooth it down. Watch out for wrinkles and bubbles, particularly in the areas close to the corners. When working with an interior corner, slightly overlap one wall with the other. Wrap the wallpaper around the edge of the outside corners, being careful to ensure that it sticks well and lines up exactly with the next strip.

Recall that accuracy and patience are crucial. Never be afraid to carefully lift the wallpaper and reapply it if you run into any problems, such as misalignment or air bubbles. You can make sure that your wallpaper corners look neat and professional by practicing and paying close attention to detail. You can use well-applied wallpaper to turn your room into a gorgeously finished space by following these tips.
