The methods of leveling the corners of the room with plaster

The question of flat walls is one of the most important when it comes to finishing work. But no less important, when the corners in the rooms will be flat at 90º.Therefore, the question of how to level the corner of the wall with plaster mortar, one of the often found on the pages of construction forums. In the rooms are always present as internal corners, and external. Therefore, it is necessary to understand two alignment processes, which differ slightly from each other.

Please note that it is best to level the plaster if the deviation from the straight is not very large( 87º-92º).If this figure exceeds the standards, then it is best to use for drywall plasterboard.

Aligning the outer corner of the

Let's start with the question of how to align the corners of the walls( external)?Usually they are located at the door, rarely when there is a column or an architectural ledge in the room. But in any case, they must be fitted in a straight line.

• The deviation is primarily determined. For this, a square is applied to the corner. The long part of the tool should lie on the main wall, which must already be plastered. Usually under it the ledge is fitted.
• If the angle is sharp, then the adjacent surface must be leveled.
• First install plaster beacons - evenly over the entire height.
• Then apply the plaster on the adjacent wall. That is, simultaneously the surface of the wall and the outer corner are leveled.

Most likely, small deviations still remain. Therefore, it is necessary to wait until the plaster layer has dried, after which the angle must be treated with a primer. When it dries, it is possible to carry out final alignment with putty( thin layer), using an angled spatula.

Aligning the inner corner

Solving the question of how to align the inner corner of the wall is more complicated. Sequence of work:

• A metal profile is installed on one wall at a distance of the blade width of the corner trowel, which is fixed to the wall with three metal dowels. The installation should be strictly vertical, for which the level is used.
• A plaster solution is applied to the adjacent wall with a small trowel. The plaster is applied in small strokes to the entire height of the aligned corner.
• Now with a corner trowel, it is necessary to level the mortar so that the gap between the tool blades and the wall surfaces is completely filled with plaster.
• The profile is removed, it is expected when the applied layer dries, after which it is necessary to prime the angle and carry out additional leveling with a thin layer of putty.

As you can see, plastering the corners of the walls with your own hands is not the easiest process. But if you understand it, it turns out that it is not a problem to do it yourself.

Modern way

Building technologies today quickly change, moving into the category of "simple in performance."Therefore, the question of how to plaster the corners of the walls can be solved in a simpler, modern way. To do this you will need a special detail - a metal counter. In fact, this is a straight corner made of aluminum, to which is attached a mesh. Conrasultz is used to form corners.

In order to install it, it is necessary to apply a thick layer of plaster mortar right in the corner. It is better if it is thick. After that, this mesh corner is installed over the not dried plaster. Note that the verticality of the Conasultian installation is the main requirement. The metal corner itself is a soft piece, so it's best to use a long rule to press it down to the corner of the room.

At the same time, from the leveling device, squeeze out part of the plaster solution, which must be removed. Now it takes time for the solution to dry out thoroughly. The rest of the angle alignment process is performed using standard technology. In fact, this is the usual alignment of walls that are adjacent to each other. That is, first one wall is leveled, then the other. At the same time, the net of the Conaxult is inside the applied layer of plaster, which will make the solution stronger. A metal corner will provide 90º.
