How to glue wallpaper in the corners

Any room can be made over with wallpaper, but the tricky part is usually finding the corners. It can be a little difficult to achieve a smooth, seamless finish when working with inside or outside corners. Fortunately, professional-looking results are achievable with the appropriate methods and a little perseverance.

It is important to prepare all of your tools before you begin. A straight edge, a seam roller, a sharp utility knife, and high-quality wallpaper adhesive are required. Getting your corners ready will simplify the process and increase the likelihood that the wallpaper will adhere firmly and look fantastic.

Because walls are rarely perfectly straight, inside corners can be especially difficult. This implies that wrinkles or bubbles may appear when the wallpaper is simply folded into the corner. Here’s where it gets important to measure and cut the wallpaper precisely so that it overlaps the corner just a little.

Conversely, to avoid peeling, outside corners call for a different strategy. It’s imperative to make sure that the wallpaper covers the corner securely and that any overlaps are seamless and undetectable. Pressing the wallpaper into place and preventing air pockets can be achieved by using a seam roller.

You’ll be well on your way to becoming an expert at adhering wallpaper to corners if you keep these pointers in mind. Recall that meticulous cutting and measuring combined with patience will pay off in the end by providing your walls with a beautiful finish.

Preparatory activities

To ensure that there are no issues during the process, steps should be taken beforehand to remove outdated finishes and unevenness. Although the room appears to have a flat layout from the outside, the flaws are revealed when measuring with a building level. As a result, the wallpaper—not just in the corners—will appear uneven; the joints won’t be vertical, creating unsightly creases, and the product images will move. Consequently, the repair will need to be redone from scratch.

Using a spatula or sandpaper, the surface is cleared of dust, old plaster, or dirt. Putty the necessary amount to remove curvature and voids. The material undergoes priming and sanding after it has dried. This material strengthens the bond (adhesion) between the walls and the finishing material’s surfaces. Applying one layer, waiting for about thirty minutes, and then applying the second layer is sufficient. Experts apply wallpaper glue on top of the primer layers five hours prior to work commencing.

The sockets and switches must be de-energized before their covers are taken off and put back in place.

Perforated corners are used in the alignment process. They shield the joints from damage in addition to making them look better. Cardboard corners will work for minor imperfections; in other situations, PVC products will work. The steps are as follows:

1. Check the verticality using a plumb line or laser level.
2. Align the profile according to the level, filling it with putty.
3. After drying, treat with a layer of putty. If you plan to paste with paper or non-woven material, the profiles are additionally sealed with finishing putty.

It can be challenging to achieve a smooth and seamless look when gluing wallpaper in the corners, but patience and technique are key. Make sure the walls are smooth and clean before cutting the wallpaper into small, manageable pieces. Smooth out any wrinkles or bubbles as you go. Evenly apply the adhesive, then press the wallpaper into the corner using a brush. By carefully trimming any excess and taking the time to align patterns correctly, you can give your corners a polished and cohesive look that will transform your space.

Materials for work

The following are necessary tools:

1. A utility knife for removing excess trellises.
2. Pencil.
3. Spatula about 15 cm wide.
4. Roulette.
5. Scissors.
6. Roller.
7. Brush.
8. Clean cloth for ironing.

Gluing technology

Following surface preparation, we start adhering the products to the door or window. Applying veneer to every joint at once is unacceptable. First, pick one after you’ve made a strip and applied glue to the wall and the profile (if the material the rolls are made of calls for it). We only glue wallpaper in one direction, either from left to right or right to left. We ensure that every component is precisely level. Then, gradually smooth out the finish to remove any air bubbles using a clean, soft cloth, roller, or plastic putty knife.

In the inner corners

In the rooms, there are more joints of this kind. The order is as follows:

1. Cut the canvas to width, leaving 1.5 cm for folding onto the adjacent wall. If there are unevennesses, the width of the fold should be 5 cm.
2. If, when pasting non-woven wallpaper, a wide piece remains on the edges of the walls, it can be used on an adjacent wall, provided the patterns match.
3. The canvas is pressed against the wall with a spatula for a tight fit.
4. When folds appear, the edges are trimmed towards them.
5. Trellis on an adjacent surface should overlap with the edge, and the canvases should be aligned along a vertical line.

In outside corners

The steps are as follows:

1. Place the product with the possibility of turning it 30 cm behind the adjacent surface.
2. If the edge wrinkles, leave the fold width 0.5–1 cm.
3. The edges of the trim protruding outwards are protected with PVC profiles, which are attached after installation work.

Measure the width of the roll, take a 5 mm step back, and mark the spot to line the next strip. Working along the resulting vertical line, you can continue.

In order to conceal the flaws, the wallpaper will be adhered to one another so that a portion of the unevenly cut edge hides behind the other strip.

Gaining proficiency in adhering wallpaper to corners can significantly alter the appearance of your space. It all comes down to technique, patience, and accuracy. You can achieve a seamless, expert-looking finish by precisely measuring, cutting, and aligning your wallpaper.

Don’t hurry things along. It’s important to take your time when applying wallpaper to prevent creases and bubbles, particularly in difficult corners. As you proceed, don’t forget to use a gentle brush or sponge to remove any remaining air bubbles.

These actions can completely change a space and give it a modern, polished look. Even the trickiest corners can be confidently handled with practice, giving you beautifully finished walls.

Continue to try new things and hone your skills. You’ll soon discover that adhering wallpaper to corners is an easy task, and you’ll be able to admire the finished product—perfectly decorated spaces.
