Gypsum cardboard has long occupied its niche in the market. It enjoys well-deserved popularity, as it is a universal material that can be attached to walls or ceiling or used as a partition. However, depending on the installation site, the installation methods will change, and various tricks will appear, which must be taken into account when carrying out work. 
Drywall is used to level the walls andceilings in the room. can be done in several ways: on a metal or wooden frame or on glue. Each method has its own advantages and disadvantages. It is worth considering them in more detail.
Wall mounting by wireframe: necessary materials and tools
This method is applicable for any roomregardless of their size and destination. The frame is used when closing walls and ceilings, as well as when erecting a partition from the GCR. It is worth noting that the crate in all cases is almost the same. 
Nomenclature of profiles for GCR. At the initial stage, it is necessary to prepare all materials and tools. To carry out the work you will need:
- perforator;
- Screwdriver;
- a hammer;
- mounting knife;
- Self-tapping screws for wood or metal (depending on the material of the crate);
- scissors or hacksaw for metal;
- drywall;
- profiles or slats;
- mounting hangers;
- pencil;
- level;
- roulette;
- plumb bob;
- gon.

Wall preparation and foundation marking
Important! Preparation of the substrate includes cleaning the wall from easily peelable coatings, repairing in the presence of significant damage, deformation removal.

From the wall to be closed, it is necessary to indent the distance necessary for the laying of communications and insulation. Further, the location of the guide profiles located on the floor and ceiling, as well as on the walls, is noted. All guides must be in the same plane. Then it is noted where the racking profiles will be located. The distance between them should be 40-60 cm. At the same time, it is necessary to calculate the distance in such a way that the edges of the sheets of gypsum board fall on the profiles, and do not fall into the gap between them.

Mounting of the frame for GKL
Next, the frame is assembled. First, the guiding profiles are installed on the floor and ceiling. It is from them that the reliability of the entire structure will depend, so it is necessary to fasten them carefully. The installation of the profiles is done using dowels in 40-60 cm increments. Further, the guides on the walls are installed in a similar way. 
Scheme fastening metal frame underdrywall. Then mounting plumb lines are mounted to the wall along the line of load-bearing profiles. The step is 60 cm. On adjacent lines it is advisable to shift the plumb lines relative to each other. You can arrange them in staggered order. This will give greater strength and rigidity to the structure. Further, rack racks are inserted into the rails and they are placed in their places. They are attached to the guides and to the plumb lines. Self-tapping can be used for this operation. If the plumbs have "ears", they should be wrapped inside the frame. After the installation of vertical profiles, the installation of transverse profiles begins. All operations are performed in a similar manner. If the profile is too long, it can be cut using a hacksaw or metal scissors. If, on the contrary, it is short, then it is necessary to increase the length using special connectors. The rim of the wooden bars is collected similarly. Back to contents</a>
Installation of GCR on the walls
The last step is the installation of plasterboard. However, before proceeding to the final stage, it is necessary to solve the problem with noise and heat insulation of the room. As a heater can be used mineral wool, sheets of foam, cork. All these materials absorb sound well. Installation of communications, the laying of engineering systems is carried out before the walls are sewn up by the GKL. When the room is insulated and all communications are summed up, you can start installing the sheets. For this you need metal screws. Important! GCR is drilled every 30-40 cm to all the profiles of the frame. During installation, the following rules must be observed:

Pros and cons of this type of drywall installation
On the positive sides this method is much more, more often it is used it:
- even walls with significant swings, pits or protrusions are leveled;
- all flaws in the ground are masked;
- reliable fastening of plasterboard;
- there is no need for thorough preparation of the foundation, its leveling, etc .;
- possibility of additional warming and soundproofing of the room;
- absence of "wet" operations;
- can be used in any room.
There are only three basic shortcomings:
- reduction of the area of the room;
- low maintainability;
- For GKL there is no solid wall.
If the collection of the frame seems too troublesome, then you can try to simply glue the material on the walls. Back to contents</a>
Fastening of plasterboard on glue
It is not always possible to paste drywall. Use it only if the following conditions are met:

If at least one of these conditions is not met,It is better to use the wireframe method of fastening. You can not glue the plasterboard on the ceiling: in this case the crate must be used. Of the special advantages of this type of installation can be noted the economy of space. It is very convenient in small rooms. Back to contents</a>
Pre-treatment of walls
Scheme of wiring installation under gypsum board. Before gluing the GCR, it is necessary to separate the wiring. All cables must be recessed into walls, in strobes. Also, you can close the wires with special cable channels. To glue the drywall you need to prepare the walls. They need to be cleaned of wallpaper, old paint, dirt, dust and oil stains. If necessary, straighten strong cavities. Then dry it. To improve the adhesion and reduce the moisture-absorbing properties of the walls, they should be treated with a special primer. It, too, must dry up. Only after the completion of all the preparatory measures you can proceed to gluing the GCR. Back to contents</a>
Required materials and tools for gluing the material
To carry out the work you will need:
Scheme fixing gypsum board to the frame. The way of gluing depends on the features of the substrate. This will affect the materials used. If the differences do not exceed 5 mm, then plaster putty is quite suitable. The works are as follows. The sheets are cut so that after gluing there is a gap to the floor of 10-15 mm, as the plasterboard will be installed on the trimming linings. The fact is that the gypsum glue for drying needs air. Subsequently, the scraps are removed, and the gap is sealed with a sealant. This is necessary to ensure that the GCR does not absorb moisture from the floor or from the screed. The sheets must have communication holes. To hit were as accurate as possible, the trimming is best done after pasting the previous sheet. On the prepared material with a notched trowel around the perimeter and in the center a plaster putty is applied. This will avoid the sagging of the material and allow it to be installed on the wall evenly. If something is attached to the wall, for example, a shelf, then it is better to apply the adhesive compound with a continuous layer. Then the sheet rises and is attached to the wall. To make it convenient to take a sheet, you can put it on the flooring of the boards. The bulging parts align, for this you can use the board and a hammer. When the adhesive compound has dried, it will be necessary to seal the joints between the sheets and seal the gap where the pads were placed. For uneven walls you will need a special glue "Perlfix". It is applied by piles on the entire panel with an interval of 250 mm. Then the GCR rises and is attached to the wall. Leveling, rule and board with a hammer are used for leveling. You can apply a marking to the floor and ceiling to make it easier to align the material and make sure that the panels are in the same plane. In fact, there is nothing difficult in these works. First you need to think everything over, calculate, and only then do it. </ ul>
