Wallpaper is one of the most affordable materials for finishing even not very high-quality and even walls. They can perfectly hide uneven spots and even distortions. But gluing them on a completely curved surface is not easy inconvenient, sometimes even impossible. Therefore, the first step is to align all sections of the wall as much as possible, and the corners should be given the greatest attention. If in other sections of the wall the wallpaper cloth acquired elasticity from impregnation with glue and could stretch, then surprises in the form of distortions and large folds are not excluded at the curved corners of both internal and external.
Even at perfectly flat corners, sometimes difficulties arise. Therefore, before starting work, you should prepare well for gluing wallpaper in the corners.
Where to start gluing?

Many recommend from the window, and some from the door. In reality, there is no difference, if you do not take into account the past trends, when the wallpaper had a special edge for overlap. Because of what they had to glue them with an overlap of at least 1 cm. In this case, the best option was to glue it from the far wall with a window. So there were no seams visible when entering the room. Today, wallpapers are produced without this edge, and it is recommended to glue them back to back. Sticking wallpaper in the corners is no different from flat spaces.
The first step is to decide what kind of wallpaper are and how much glue is required to impregnate them:
- Paper ones require moderate impregnation and preliminary coating of the wall.
- Vinyl ones require good impregnation, especially when pasting them in the corners, since they are quite thick and dense.
- Non-woven wallpaper requires impregnation of walls only.
Applied tools for wallpapering
Often the wallpaper has a pattern that is not resistant to mechanical damage. Therefore, a special rubber roller or brush is required to smooth them.
Interior corner finishing
Having dealt with the types of canvases and the amount of glue, you can get to work. If the wallpaper began to stick from the corner, then without fail, using a long level and a metal ruler, it is necessary to mark in the form of a vertical line.

It should be located so that when gluing the sheet lies with a twist at an angle of 2-3 cm. The inner corner is the least noticeable, so if a small overlap is formed there, it will not be very noticeable.

If, when gluing the canvas, the edge of the sheet turned out to be not straight, then it can be trimmed with a wallpaper or an assembly knife. In this case, after each cut, it is recommended to break off the blade. Otherwise, with the subsequent use of it, scuffs and tears will occur.
The corner is where the wallpaper is most susceptible to peeling off the wall. Therefore, you should not spare glue here, the best option would be to pre-impregnate the surface in several layers.
For reliable gluing of corners, use special glue. PVA glue is perfect.
Applying wallpaper on outer corners
The rules for pasting wallpaper on the outer corners are in the perfect fit of the canvas. The option with an overlap will not work here, because it will be clearly visible. The best option would be "Cut". But in order to beautifully design the outer corner, its surface is necessary.

Further, it is recommended to pre-coat the wall surface with glue in several layers. If necessary, a brush should be used, as it is often impossible to penetrate small cracks with a roller. The pre-impregnated canvas is glued at a corner with a bend on the second wall of 2-3 cm. In this case, an uneven edge of the sheet is almost always formed. This is due to the geometry of the walls and their imperfection. The second sheet of wallpaper is glued with an overlap of 5-8 cm on the previous one. This is necessary so that you can conveniently grip it when removing it.
Then, using a plumb line, or it is better to use a long level, make an incision in both blades with a new blade of the assembly knife.
It is not worth saving here, because when the blade becomes dull, scuffs can form on the surface, which will become very unattractive.
After the incision is made, the excess piece is removed, and the edges of the joined sheets are carefully peeled off. The cut-off residue is removed from under it, and the wallpaper is glued in place. You can add glue if necessary.
Finishing the corners
Finishing the corners after gluing the wallpaper consists in rolling up the joints with a rubber roller and leveling with a special spatula.

They can also gently press down the wallpaper on the outer and inner corners. Here, the main thing is not to overdo it, because you can easily damage the wallpaper when pressed with a tool.
This video will help you figure out all the nuances when applying wallpaper in the corners.
