How you mount a wall mirror depends on its weight and size. If you want to fix your wall mirror with adhesive, you should not buy a wall mirror made of solid wood. The following types of mounting are explained here.
Adhesive tape: A wall mirror can be attached with special adhesive tape. This is adhesive on both sides. There are different types with a marking of the maximum load that can be carried. Before mounting, clean the back of the mirror and the wall. The wall and the back of the mirror must be dry and dust-free. Paper wallpaper as a background is unsuitable because it will be removed when the mirror is removed.
Dowels and screws: Large wall mirrors in particular, which are heavy, are fixed to the wall with dowels and screws so that they remain stable. To do this, mark the drill hole on the wall where the mirror is to hang. Then make sure that the dowel and the screw can be pulled over the mirror mount, otherwise you will have to use a different dowel and the matching screw. The hole must be as deep as the length of the dowel. Then hammer the dowel into the hole as far as it will go, take the screw and screw it into the dowel. The screw head must protrude in such a way that the mirror mount can be hung over it without any problems.
Hanging with screw only: Similar to fixing with dowel and screw, only the screw is drilled into the wall. However, this variant should only be used for smaller and lighter mirrors.
