Plastering of wall surfaces is performed in different ways, depending on the skill of the master. The method can be either "mechanized" or manual. But in any case, the task is one - to get the most flat plane, and no matter what plaster composition is used.
It is rather difficult to achieve the desired result if the surface to be finished is quite large. This greatly complicates the alignment process. In this case, a method is used, such as plastering walls on beacons.
What are beacons? These control "rulers", installed along the surface at a certain distance from each other. They serve as reference points for leveling the mixture layer. The technology of operation is basically the same, however, there are several ways of installing lighthouses, as well as the initial "material", which is used as such "pointers".Consider the procedure for applying to individual housing, where the rooms do not have such large dimensions as production facilities.
Technique and operating procedure for the lighthouses
On the wall are installed extreme beacons. They are placed vertically at a distance of about 20 cm from the corners of the room. Beacons most often use a steel profile. Mount it to the wall it can be different:
The first way is .Using a plumb line, a "vertical" is defined. Along it, you need to put a lump of gypsum on the wall, with an interval of 25 - 30 cm. Naturally, each wall has a certain curvature. Therefore, professionals recommend using a long wooden rod. If you attach it to the wall along the marked line, you will see where the plaster is put smaller, and where - more. By the way, there is an opinion that it is better to use "rotband" for fixing lighthouses. After that, the resulting "bumps" is superimposed profile and pressed. At the same time, with the help of the building level, "verticality" is controlled.
The second way is .Along the line to the wall are fastened clamps. With the help of the slats, their "apexes" are equalized so that the profile attached to them takes upright position. In this method, plus that you do not need to wait for the gypsum to dry. However, each clip in the store will have to pay, albeit a little.
Mounting of all lighthouses along the wall( if necessary).Such intermediate beacons are convenient to install, if between the outer profiles, the top and bottom, pull the string( twine).
Fixing profiles with mortar. It should be borne in mind that the lighthouse follows the entire length of the beacon. After this, wait until the solution dries.
Plastering between installed beacons. We must not forget that for a quality finish, the thickness of the layer should be at least 2 cm. If you have to make it thicker, then the work is done in several ways( the solution is laid in layers).Each layer must be trimmed with the rule( rod).Then there will not be large "bends" of the surface.
After applying the last, "top" layer, it is also aligned with the rule with the orientation to the beacons.
After complete drying of the plaster, the beacons are neatly broken out. The resulting furrows are covered with a solution and smoothed.
Invited "pros" such work is estimated quite expensive. If you do everything yourself, you can save a lot on this.
