Cтроителями three ways of facing of walls gipsokartonnymi are applied by sheets:
- on mouldings from gipsoopilochnoj mastics "яюф яЁртшыю";
- on a skeleton from strips gipsokartonnyh sheets;
- on a wooden skeleton.
At the first way works conduct in such sequence:
- preparation and proveska surfaces;
- a marking of an arrangement of sheets on a revetted surface;
- open also preparation of sheets;
- the prepared mastics;
- priklejka sheets on walls;
- processing of places of interface of sheets and their adjunction to overlappings.
Under each sheet on a finished surface put in chessboard order separate mouldings in diameter 10... 15 sm, maintaining between them distance no more than 40 sm (fig. 95). Under the edge of the first sheet turned to following sheet, mastic put such width that it acted from under an edge of the first on 45... 50 mm. The first sheet establish strictly vertically, checking rejkoj with a plumb.

1 - a rule; 2 - gipsokartonnye sheets; 3 - prospirits; 4 - mouldings from mastic; 5 - a strip from mastic
Then take special step malku (fig. 96) and with its help level an acting strip of a solution. Malka one ledge slides on edge of adjusting sheet. The second ledge which lies below the first for the thickness obshivochnogo sheet, levels a solution strip, creating an excellent beacon for installation of the second sheet. Joints between them will be rigid. So consistently revet all walls.

It is necessary to remember indispensable rules before to begin installation of sheets by any way.
Sheets have obverse and back parties Back that where cardboard joints are visible. If it is erroneous to put sheet the back party outside, it will be difficult to process a wall so that cardboard seams were imperceptible.
All sheets establish so that their bottom edge was on 5 sm above wearing floor level. After all floors wash and, if not to leave a backlash the sheet will absorb dampness, will deteriorate. The remained crack close a plinth and carefully coat with a cement mortal.
It is necessary to know in advance, how after facing will finish a premise if to glue wall-paper on joints of sheets do the closed seam. Put sheets, leaving a backlash from each other in the width 3... 5 mm. On joints then will put a layer shpaklevki, will stick with a gauze and again proshpakljujut.
If walls are going to paint, joints will not hide. They should be underlined on the contrary, as an architectural detail. It is for this purpose important, that the backlash between sheets was everywhere identical and strictly vertical (it is necessary, using rejkoj with a plumb to check and vertical position of edges).
To receive rust identical width on all length, take, for example, two small slices of gipso-cardboard sheet and insert them at installation of facing sheets above and below between them. Seams fill with a solution and there and then embroider, using for this purpose special small poluterkom from which bottom party the semicircular platen 10ХЮ mm is fixed. Move semigraters from top to down and then from below upwards.
When facing will reliably seize, slices GKL take out also emptiness after them fill with a solution.
Sometimes arrive and in another way. Seams do not embroider, and in a backlash between adjacent sheets on glue "¤хЁьшэшф" insert polyvinylchloride apportions.
the Second way facings - installation of sheets on a skeleton from strips same gipsokartonnogo sheet.
Preparatory operations spend in the same sequence, as in the first case. When the turn raskroja, at first raskraivajut strips GKL for a skeleton comes. Width of strips - 50... 70 mm. The central beacon on which sheets are joined, should be in the width 100... 120 mm.
By preparation of surfaces installation sites of sheets should be already marked, control marks are put. Now it is necessary to build a skeleton.
Having cut the quantity of strips necessary for this purpose, prepare for their label the first portion of mastic. To brick and concrete walls and marks put beacons on gipsoopilochnoj to mastic. If it is necessary to stick together a beacon from several strips (when that is demanded by alignment of walls), slices GKL stick together with each other sulfatno-plaster mastic. On it paste on a beacon and obshivochnye sheets.
On fig. 97 the scheme of an arrangement of a skeleton from strips gipsokartonnogo sheet is shown.

1 - gipsokartonnyj sheet; 2 - gipsoopilochnaja mastic; 3 - marks from floors GKL; 4 - a skeleton from strips GKL
The Skeleton leave on 2,5... 3 ch that mastic has reliably seized. At this time conduct open sheets, prepare mastic for their label.
The Worker smear a thin layer of sulfitno-plaster mastic on beacons and marks (only on what are intended under the given sheet!), imposes on them sheet and presses a rule. That the sheet did not slip, it krepjat 5... 6 nails. Hats of nails cover with mastic.
The Cycle comes to an end with processing of seams and places of an adjunction of sheets to overlappings.
And, at last, about the third way to facing of walls - on a wooden skeleton.
For a skeleton take antiseptirovannye and antipirirovannye wooden bars section 40X25 mm.
Having prepared surfaces, having marked the locations of bars of a skeleton, them krepjat to a wall screws or nails in wooden stoppers. Screws or nails should be zinced or kadmirovannye.
On fig. 98 the scheme of fastening GKL on a wooden skeleton is resulted.

1 - gipsokartonnyj sheet; 2 - screws or nails; 3 - a cross-section bar section 40x25 mm; 4 - vertical exhibitions from a bar section 40x25 mm; in - width of a sheet material
In public buildings (shops, schools, etc.) where the bottom of a wall wears out more likely, arrange in the bottom of the panel. For this purpose on facing from vertically put sheets put below horizontally second layer. So the panel in height of 1,2 mm (on width of sheet) turns out. The Same panels arrange low walls of staircases.
Low put a plinth in height 15... 20 sm from one-two numbers of a ceramic tile or from a cement mortal.
The Second layer of sheets paste without beacons, using for this purpose sulfitno-plaster mastic.
