The most recognized and universal building material, of course, is drywall. Being a bright representative of the "dry" way of interior finishing of apartments, drywall has been firmly and permanently entered the construction industry.
Types of plasterboard
Drywall is conventionally divided into four types:
• ordinary drywall (GKL)
• with increased resistance to fire (GKLO)
• Moisture-proof (GKLV).
Typical drywall is used everywhere for buildings or rooms with normal humidity. Has a color: gray and blue.
Gypsum board with increased resistance to flame has in its composition special reinforcing additives. Has a color: red and gray.
Moisture-resistant plasterboard is used in the premises of apartments where the humidity level is high or high enough. Has a color: blue and green.
The standard sheet of Knauf wallboard is 1.2 x 2.5 m thick and 12.5 mm thick.
Preparation of the walls of the apartment before installation
Before installing the drywall sheets, the working surface of the walls is prepared. The walls are cleaned of the old plaster layer or wallpaper, dust and dirt are removed, as well as fragments of materials. If the surface of the wall in the apartment does not have an ideal flat surface, to fix the first sheet it is necessary to fix the "beacons".
Ways of fastening drywall
The technology of leveling the walls of the apartment for plasterboard finishing and fixing methods are divided into:
• glue
• frame.
Adhesive mounting method
For gluing method of fixing the sheets, horizontal stripes of gypsum board are attached on the floor and ceiling beforehand around the perimeter of the room being repaired. The width of the strips should be about 100 mm. Fastening of strips is made by screws for gypsum cardboard.
Now, vertical strips are fixed to horizontal strips at a distance of 600 mm. The resulting wire mesh will serve as the basis for subsequent gluing of the sheets. For gluing the sheets, special adhesive "Knauf Pearlfix" is used. The glue is applied to the inside of the sheet along the perimeter with droplets. Glue drops are located at a distance of 250 mm from each other. In the middle of the leaf, the droplets are placed along at a distance of about 350 mm. Then the sheet is carefully mounted on the wire mesh.
Drywall, methods of fastening, which always cause controversy when leveling the walls, perfectly holds on the adhesive basis.
But the special popularity in the preparation of the walls of the apartment with their own hands for the subsequent finishing has received a skeleton method of fastening.
Frame attachment method
What is remarkable about the skeleton method of fastening drywall sheets? With this method, the work is simplified to a minimum, so you can finish the walls yourself. The construction industry offers a wide selection of fastening profiles: from self-made wooden ones to metal profiles. Metal * profiles for attaching drywall to the walls are:
• main PP, PS, CW, CD
• Guide rails, UW, UD.
The main profiles are designed for significant loads and have a C-shaped shape of the edges, powerful stiffening ribs and longitudinal corrugations.
Guides are designed for low mechanical stress.
How to install drywall yourself
Installation of drywall on the walls of the apartment consists of their stages:
• marking up the installation points for profiles
• installation of profiles
• installation of drywall sheets
• Finishing work.
Use of wooden fasteners
Wooden fastenings for gypsum cardboard can be used for rooms with low humidity. For the installation of sheets as a wire mesh use wooden blocks with dimensions of 60x40 or 50x30 mm. Lower wooden rails should have a perfectly flat surface and special grooves for fastening bolts or screws.
The wooden crate for fastening the sheets is done by hand very simply.
Wooden rails of the required length are prepared. According to the preliminary layout of the wall, the rake is applied to it and aligned. With the help of screws, the slats are attached along the perimeter of the walls. The step of fixing the rails is 150 mm. so you will create wireframe guides for installation. Then, vertical racks are installed. For this purpose, holes for fastening are cut in the guide rails according to the marking and dimensions of the drain. Reiki are inserted into these holes and fixed to the wall using self-tapping screws. Checking the verticality of the rails with the help of levels. The fastening points of the rails and guides are additionally strengthened and processed with special mixtures to extend the life of the wooden frame. After that, the sheets of plasterboard are assembled.

Using metal profiles
The work begins with the marking of the installation points for the profiles. It is necessary to accurately and correctly make the markup, because the quality of the markings will depend on the quality of the sheet installation. On the walls of the apartment with a plumb, level and pencil vertical lines are applied. It should be remembered that the layout and layout of the sheets is done taking into account the size of the sheet. Then on each vertical line with an interval of 600 mm to the wall fixing direct suspensions are attached.
Direct wall suspensions are fastened using dowels with impact screws. The length of the dowel depends on the thickness of the wall (for reference: the length of the dowel for a concrete and brick wall is 40 mm). The next stage of installation is the fixing of vertical rack-mount profiles. Fasteners are made by self-tapping screws for metal. At the stage of formation of the installation framework, installation of hidden communications is carried out. All necessary wires fit behind the frame.
The most important is the installation of the first sheet.
The first sheet is laid in such a way as to cover half of the vertical profile. For these purposes I use screws so that there is no possibility to split the sheet.
The second sheet of drywall should be boldly laid with the first sheet so that the profile metal is not visible. According to this scheme, all sheets are laid and fixed. The joints between the sheets are sealed with reinforcing tape (sickle). Final plugging of visible joints and traces of fastening places is made with plaster. Your new level wall of the room is ready! Now you can make a wallpaper sticker, without waiting for the plaster to dry out - gypsum board has taken care of this too: neatly, quickly and respectably!
