This is necessary to improve sound insulation. If the house has wooden ceilings, they will need to be cleaned of plaster mix to make sure that they are in excellent condition and can withstand the weight of the suspended structure.
An example of marking a ceiling frame for plasterboard.First of all, you will need to make markings. In this case, we will consider the alignment of the ceiling structure, while no figured or multi-level products will be made. The frame for the plasterboard ceiling can be installed at the minimum possible distance from the main structure - 2.5 cm. To make markings correctly, you will need to find the lowest point on the main ceiling, step back from it by 2.5 cm, and then put a mark on the wall. Using a water level, this mark should be transferred to all external and internal corners of the room. If you plan to build any lighting fixtures and other equipment into the ceiling structure, you will need to determine the lowest point and put down the height of the lighting fixtures from it. The level will be beaten off according to the new mark.
Installing plasterboard sheets usingT-shaped stand. Between the marks that were applied to the wall, it will be necessary to draw control lines. This can be done with the help of an ordinary thread, which is wound on a cassette and covered with blueing. The thread will need to be pulled between several marks, after which, having pulled it a little, it is necessary to release it sharply. As a result, you can get a straight line, which can be used as a guide during the installation of the frame of the suspended structure, it will mean the lower limit of the frame. The frame will consist of several metal profiles, therefore it will be necessary to beat off several lines on the main ceiling. To do this, it is necessary to choose a corner of the room, which is close to 90 °. Next, you need to decide on the direction of the plasterboard sheets. During the installation, it is necessary to mark two opposite walls every 50 cm along the direction of the ceiling. After this, it will be necessary to sheathe the lines between the marks along the ceiling structure using a chokline.

These devices rest against the main structure, so you will need to fill the level with water to capacity. To avoid this, the flasks must be removed. Self-tapping screws for plasterboard sheets should be used to secure metal profiles. It is imperative to check their quality as follows: if the self-tapping screw put on the nozzle does not fly off it in a horizontal position or with a slight downward tilt of the fastener, this means that it is of high quality.

One person will not be able to lift and screw the gypsum plasterboard on their own. In this case, self-tapping screws for metal are used for installation, which are 25 mm long. The installation step of these devices is 30 cm. The cap of the fastener must be recessed into the gypsum plasterboard sheet, otherwise it will interfere with the puttying later. However, you should also take care that the cap does not break the paper. To do this, it is recommended to use a special nozzle with a lampshade, which can fix the depth of immersion of the cap.
Cassette ceiling installation diagram.The installation scheme of the sheets is simple: the outer part of the plasterboard sheet should lie on the CD profile, overlapping it by half. This is the only way to level the ceiling. The other half will be occupied by the next sheet. After installing all the sheets, you will need to start sealing the seams and installed fasteners. In some cases, the surface of the plasterboard sheets may be uneven, for example, a small groove may run along the edges of the material. Therefore, the plasterboard sheets will also need to be processed before applying finishing materials. For this, special gypsum-based mixtures should be used. The minimum layer thickness of such a mixture is 0.5 cm, the maximum is 5 cm. The solution is applied in a thin layer. If you cannot level the plasterboard ceiling in this way, you will need to apply this mixture in a thick layer. After applying the plaster, you will need to wait until it dries. Then it is rubbed with a hard sponge, which must first be moistened in water. This will eliminate the roughness of the base. Leveling the ceiling with plasterboard sheets is a simple process, you just need to prepare all the necessary tools and materials, and strictly follow the sequence of actions.
