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

Preparing wall corners

Even if the walls are plastered along the lighthouses and high-quality plastered, this does not mean that everything is in order with the corners. Shallow grooves and grooves are unacceptable, they are putty. Ideally, when puttying and subsequent sanding, the inner corner is given a minimum radius of curvature.

This will completely remove excess glue and air during pasting. When preparing the outer corner, it is imperative to use a perforated corner. This will help create straight lines and properly wallpaper it, protect against plaster collapse in case of light blows that occur, for example, when furniture drifts.

When applying the primer to the walls, a roller is used. Use a brush for thoroughly priming corners. Choose the order of the sheets and decide where to start. It may be more convenient to start at the edge of a window or doorway. Start by choosing a wall with a less noticeable angle, such as where the cabinet will stand.

Pick up a narrow strip of wallpaper cut from a roll to the width. Walk with her along the selected wall, trying the options for the location of the sheets. When choosing the option of how to properly glue the corners with wallpaper, strictly follow the rules:

• sheet joints in the corners are unacceptable;
• no matter how even the corner may seem, do not plan to paste over it with a solid sheet;
• instead of an overlap sticker, use an overlap sticker followed by a double cut.

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

You can apply barely noticeable marks a centimeter in length every 20-30 cm and draw a line not from the very junction, but, say, one centimeter to the left or to the right, so that later this line will close. Such an inconspicuous line will serve as a reliable reference point and will not show up later at the very junction, as it sometimes happens.

Gluing the first canvases

Recall the sequence of the sticker:

• Open the wallpaper with or without pattern selection (according to the instructions in the roll).
• Apply glue to walls, canvas, or to walls and canvas (according to the instructions).
• If the sheet is glued, fold it over to prevent the glue from drying out prematurely.
• Stick the canvas on the wall from the ceiling downward, guided by the vertical mark or with the extreme edge of the already glued canvas, aligning the pattern.
• Carefully remove the remaining air with a roller or brush, smoothing from the center to the edges.
• Using a wide spatula with a stationery knife, trim the top and bottom of the panel, smooth it again with a roller, if necessary, coat with glue and smooth again.

How to glue the wallpaper: inner corners

1. We cut out a strip from a single piece, 5 centimeters wide than the distance from the last piece to angle (measure at the ceiling, in the middle and at the floor, take the largest one), the remaining piece will be glued after first.
2. We coat it with glue (according to the instructions for the wallpaper) and glue 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, draw a vertical line for sticking the remaining piece of canvas so that it is glued with an overlap of 2 cm on 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 out the remaining glue and air.
6. We are preparing a knife, for 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 off excess, if necessary, bend the edges and finish with glue, roll it in with a roller.

After double trimming, an inconspicuous joint remains. If it doesn't work the first time, remove the glued strips and repeat with great diligence. It will definitely work, and you will know how to properly glue the wallpaper in the corners.

How to properly wallpaper the outer corners of a room

Pasting the outer 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 over with a solid canvas.

After gluing the first corner piece of canvas, the rolled-up part of the wallpaper must be at least 5 cm. The next canvas with glue along the markings so that the overlap in the narrowest part is at least 2 centimeters.

Thoroughly drive out the remnants of glue and air. We prepare the knife blade and, applying a wide spatula, cut off both blades without tearing. We remove the excess, glue it and roll it in if necessary.

Useful expert advice

• If you find an air bubble and it does not smooth out, pierce it, remove the air, pour 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 is chewed. Let them dry a bit and cut again. Perhaps the knife is dull and it's time to change the blade.
• Avoid drafts in the room, this can lead to premature, uneven drying and flaking of the sheets.
• Unplug and frame outlets and switches in the room ahead of time. You can put it back in place immediately after pasting.
• When gluing to problem areas, add 10% PVA glue to water while preparing the glue.
• If old wallpaper is difficult to remove, wet it with a primer using a paint roller. Remove immediately before the primer is dry.
