Since the XV century, in European countries began the widespread use of gypsum. Such a "plaster of Paris", namely such a name was given to the gypsum, was used for interior decoration of buildings. Today, any repair is impossible without the use of drywall.

Main qualities of plasterboard
What you need to know about drywall for its comfortable use as a building material?
Initially, a sheet of drywall was perceived as an alternative to the plaster layer and plywood. However, over time, new types of sheets began to appear, intended already for rooms with high humidity and invulnerable to fire. What was the attractiveness of the drywall sheet?
It is necessary to note important qualitative properties:
• nontoxicity of the material
• porous structure
• non-flammability and fire resistance
• easy operation and installation.
As a part of plasterboard there are no harmful impurities and salts of heavy metals. On the contrary, these are natural components that do not have a negative effect on the skin and respiratory organs of a person. Suffice it to recall the use of gypsum in medical manipulations: "woke up - plaster."
The porous structure of gypsum allows to absorb and give water from the environment, and this means to carry out a natural circulation. It is impossible to set fire to drywall. "Dry" method of installation of drywall eliminates dirt, debris and other uncomfortable conditions of repair. Convenience at installation allows to embody all design ideas and decisions. Working with plasterboard is convenient, because the standard dimensions of the sheet can be customized to any work surface. Plasterboard structures have a negligible weight in the repair or reconstruction of apartments and premises.
Wealth and diversity of species
If you pay attention to the color of the sheets of drywall, you can immediately detect the difference. This is indeed so. Conditionally drywall is divided into several types:
• GKL - ordinary plasterboard (gray color)
• GKLO - plasterboard of increased resistance to negative flame effect (red color)
• GKLV - moisture resistant gypsum board (green color).
A conventional drywall is used everywhere for rooms or rooms that have a normal moisture regime.
Gypsum cardboard, which has increased resistance to negative flame effects, with special reinforcing additives.
Moisture-resistant plasterboard is used in rooms and apartments where there is a significant level of humidity.
Therefore, when choosing gipsokartonovyh sheets you need to pay attention to the color and thickness of gypsum board. The thickness of the cut sheet 9.5 mm will be insufficient, for reliability it is recommended to choose a thickness of 12.5 mm. A typical greyish-colored gypsum cardboard can be used to work in almost the entire apartment. Moisture-resistant plasterboard greenish shade with silicone impregnation is most applicable for bathroom and kitchen.
When using moisture resistant sheets in wet rooms, after installation, the front side is treated with waterproof primers and putties. Primer surface should be made two times. Places of installation of gypsum board with intensive moistening are covered with a waterproofing layer.
The composition of fireproof gypsum cardboard eliminates the possibility of fire and smoldering. The red color of fire-resistant plasterboard, whose core, even without impregnation, will signal the safety of the application. Fire-resistant material is significantly different from the usual for the price.

Sheet dimensions
The standard size of a drywall sheet of factory production is:
• length - 2500 mm.
• width -1200 mm.
• The thickness is -12.5 mm.
Sometimes the length of the GCR can be in the range of 2-4 m. However, the width of the sheet remains the same: from 600 mm to 1200 mm. The thickness of the sheet drywall depends entirely on the purpose and is from 6.5 to 24 mm. The most demanded is the thickness of the sheet 9.5 and 12.5 mm. Depending on the thickness of the sheet, the weight of the material is different. Insignificant weight gipsokartonnyh designs allows to use and apply two kinds of fastening.
Methods of fixing plasterboard sheets
Methods of fixing gypsum cardboard depend on the type of working surface, moisture level and thickness of the sheet itself.
The methods of fastening with the technology of leveling the walls with subsequent finishing with plasterboard are divided into:
• glue
• frame
Method of fastening glue
With the gluing method of fastening, a lath is arranged around the perimeter of the room. Fastening of strips of a lath to a wall is made by special self-cutters for gypsum cardboard. The resulting carcass lath is the basis for subsequent gluing. For gluing and mounting sheets used glue "Knauf Perlfiks" or Plast.
This glue is applied evenly on the inner surface of the leaf with drops 250 mm apart. For the best gluing in the middle of the sheet, I place the glue along along the glue. The sheet to be mounted is pressed lightly onto the frame crate.
Fastening method frame
The frame method of fastening is most applicable because of the simplicity and efficiency of installation. The construction of the frame for fastening is several hours. Fastening profiles are used for fixing sheets of gypsum board: wooden and metal. Metal profiles are distinguished on the main and guides. The main profiles include: profiles of PP, PS, CW, CD. To auxiliary - Mon, UW, UD.
For fixing the frame method, in addition to the selected metal profiles for mounting and boards, it will be necessary to use pin dowels and gypsum board screws. The length of self-tapping screws for work is chosen according to the scheme: the thickness of the sheet plus 1 cm. For mounting on the skeleton and glue methods, the plates must be installed closely.
Fasteners (self-tapping screws)
Self-tapping screws with a frequent and sparse thread pitch are used as the main fastener for sheets.
The screw has a countersunk head with Phillips Phillips No. 2, a frequent or rare right-hand thread and a pointed tip. Coverage is black, less often gray phosphate or yellow zinc.
Fasteners having a frequent or infrequent thread pitch are used for fastening without pre-drilling.
