Both amateurs and professionals have already appreciated such a device as a laser level. After all, using this compact device, you can create absolutely precise markings vertically and horizontally on almost any surface in real time.

Previously, to solve such problems, various levels (spirit, hydraulic, etc.) or plumb lines were used, which required certain skills and quite a lot of time. However, after the advent of laser levels, beginners can also cope with such work, and the scope of this device is constantly expanding, especially in the field of construction, decoration, repair of buildings and other structures.

Builders use these handy devices:

• when leveling walls, ceilings and floors;
• for marking partitions and guides in suspended ceilings;
• perfectly even laying of floor and wall tiles;
• wiring installation;
• sewer connections.

Listing all areas of application of laser levels is a thankless task. However, it is worth mentioning that with this device you can hang a picture or a shelf and even glue wallpaper.

Consider the last option, which looks extremely unusual, in more detail. Let’s start with the fact that the walls of Russian apartments and houses are rarely perfectly even. Therefore, professionals first make the markup, and only then begin to glue the wallpaper, because only in this case will they be completely equal.

Very often this task is solved with the help of a primitive plumb line and an ordinary pencil or marker, with which a line was drawn on the wall. There are many drawbacks to this method. First, manual tagging is very time consuming. Second, there is a high probability of errors in measurements. Third, after smoothing the wallpaper at the seams, marker or crayon stains may appear.

You can avoid all these problems with the help of a laser level, which in a few seconds will “draw” a perfectly even line on the wall. In this case, you need to act according to the following scheme:

1. We take a tape measure in our hands and measure the distance between the middle of any corner, which should be one centimeter less than the width of the wallpaper. This centimeter will help us solve the problem of wall curvature.
2. Make a mark with a pencil or marker.
3. We place the laser level on a flat surface and direct the beam to a point on the wall.
4. We wait for the device to build a uniform vertical line on the wall, and we coat the first strip of wallpaper with glue, then glue it to the wall exactly along the laser marks.
5. We smooth the glued strip with a spatula, remove the glue protruding from the outside with clean microfiber rags, then carefully cut off that “extra centimeter” that turned out to be on the adjacent wall.

Then we glue the wallpaper along the first strip with a perfectly even vertical line obtained using a laser level.
