How to level the walls at 90 degrees
Before performing facing works, the tile always arises the question - how to bring an angle of 90 degrees on the walls?
After all, even a minor deviation that is imperceptibly on the wall and clearly manifested in the corner will lead to the need to increase the layer of the adhesive solution in some places and reduce - in others.
Therefore, before finishing work, the vertical and horizontal of angular parameters is measured using: plumb, construction level or laser level.
After leveling lighthouses do not need to dismantle It is best to measure the laser level measurement, as the most convenient and accurate control tool, and then set lighthouses for which to output a straight angle between the walls:
- made from steel profile. They are not afraid of water, they are easily attached to the wall, have a perfectly smooth surface and are not subject to dismantling after the end of the work;
- from wooden rails with a cross section of 20x30 mm. Despite the fact that they have a number of shortcomings, due to accessibility are used more often than others. After leveling the wall is subject to extract;
- the oldest view is to exhibit beacons from the fragment of the mortar mixture. It is not necessary to delete them, but this method is often applied by experienced plasters.
With the help of what lighthouses to level the corners, as well as make walls in the rooms smooth, solves the specialist individually.
How to make an angle straight
Walls are aligned in turn It all depends on the magnitude of the slopes of the walls. Minor include deviations of no more than 20 mm. During the work, some rules should be followed:
- The exhibition of vertical beacons is mandatory.
- Compliance with the sequence when applying a solution: first the sketch is made with a liquid solution, and after it is setting it is the final alignment of the wall surface.
- The application of the thick layer of the solution is not recommended, since the mixture under its own weight fall off, without having time to grab.
- Initially, aligned with the rule of beacon one wall, then the second.
- If there is a rule in the form of a large metal salt, alignment takes place to move up-down to the beacon. Surplus the solution is cut, and in the missing places - it is pounced.
With high drops and deviations, use the reinforcing grid With the deviation of more than 2 cm, additional operations will be required:
- reinforcement by installing a reinforcing mesh;
- by braid wire on previously scored dowels, nails or screws. Depends on the wall material: concrete, brick, rikushnyak, foam concrete, foam block;
- locking dranco in wooden houses.
If the walls have a slight deviation, then the alignment is performed directly between them, as well as between the wall and the ceiling. In this case, the solution is applied to the corners and is aligned with the angular rule. Further from the angular line, the solution on the wall is reduced to no. See this video in detail about alignment of the corners:
Aligning the corners is the most time-consuming construction process, which is better to entrust professionals.
Tools for alignment
Alignment without a standard set of tools is impossible. These include:
- Rule 100-120 mm wide. It is made of aluminum rails up to 150 cm long. It allows you to evaluate all the irregularities of the wall, of its discharge and depressions.
- Wooden semiurial 50-70 cm long. Can be made of plastic or metal. It is used in order to ram the solution on the wall.
- Grater. Used in hardly available places for alignment and grout.
- Corner in the form of a straight triangle. It is made of wood or metal. With it, the surface and corners are checked. The larger the length of the parties constituting the rectangle, the more convenient it is to perform work on an angle of 90 degrees.
The table shows the building acknotes, which differ in each other in design and measurement method:
| № | name | characteristic |
|---|---|---|
| 1 | electronic | The scoreboard displays the results of the Vertical and Horizontal |
| 2 | laser | Liquid crystal display, measurement from the angle, the memory of the last 20 measurements |
| 3 | optical | Consists of glass: Limbs and plates with an index of angular minutes |
| 4 | mechanical | Inexpensive, accuracy of measurement of internal and outer corners |
| 5 | pendulum | The pendulum is rigidly connected to the showing arrow, which shows the deviation of the measured angle from the vertical or horizontal base |
Before making a straight angle, a trowel is made to throw a solution on the wall, and small irregularities are eliminated with a spatula.
It is impossible to align the corners without a solution. For its preparation, the capacity of the appropriate volume, sand with cement or dry solution is used in the finished proportion.
