Plaster surfaces from various materials both with internal, and from lateral aspect for the purpose of their alignment and warming of premises. The plasters executed from solutions, name "ьюъЁ№ьш" or monolithic. Besides, there is a so-called dry plaster - gipsokartonnye sheets, which krepjat to surfaces nails, mastics and glues. They are applied only in a building.
Besides functions of warming and plaster alignment improve sound insulation, provide smaller sgoraemost wooden designs, improve sanitary-and-hygienic conditions of residing. Correctly executed plaster is durable - serves as centuries.
Depending on properties and plaster appointment are subdivided on usual, decorative and special. usual plasters carry out under colouring and pasting by wall-paper; decorative - can be colour, with the characteristic invoice; special - carry out protective functions (can be heat-shielding, acoustic, waterproofing etc.). In housing construction apply, as a rule, usual plasters, therefore here it will be a question only of them.
Usual plasters share on simple (for uninhabited structures), improved (for apartment houses) and high-quality (for public buildings). If to check up high-quality plaster otfugovannoj rejkoj in the length 2 m at its applying to a surface between it and plaster it is supposed no more than two roughnesses by depth or height to 2 mm (for improved - 3 mm). The deviation on a vertical is supposed 1 mm on 1 m of height of a wall (but no more than 3 mm on all element). The improved plaster rub clean round, and high-quality - vrazgonku, i.e. More purely, than round.
Plaster is expedient for carrying out on directing, or to so-called beacons which can be wooden, metal (from an angular steel), rastvornymi or plaster.
Building norms and rules (SNiP) define a different thickness of plaster: simple - 12 mm, improved - 15 mm and high-quality - 20 mm. On the basis of the big practical experience I can tell: it is better to do plaster in the thickness of 20-30 mm (for wooden surfaces), considering from level the day off drani, i.e. As a whole - 25-35 mm.
During time oshtukaturivanija it is necessary to put a solution in three layers: the first - obryzg, the second - a ground and the third - nakryvka. Obryzg and nakryvku put smetanoobraznym a solution, a ground - testoobraznym. How the solution is put, durability of plaster depends.
Knitting materials, fillers and water are necessary For preparation of plaster solutions.
