Plaster consists of three layers: obryzga, a ground and nakryvki. Put them nabrasyvaniem or namazyvaniem. Namazyvanie to execute easier, but smear only solutions for a ground and nakryvki. Obryzg it is necessary to throw necessarily, but skill here is necessary. If a brick or concrete surface equal enough, it is possible to put thin layers of a solution on it, rubbing it as it is possible more strongly in various roughnesses of a surface.

On concrete surfaces plaster can be in the thickness to 5 mm. On brick it it is desirable to do slightly more thickly, for example, 10 mm. Through more thin plaster will appear through laying seams. Thin plaster is more economic, but it less warm and faster collapses.

solution Drawing on walls kelmoj: and - nabiranie a solution on the falcon, - zabiranie a solution kelmoj from the falcon, in - solution drawing on walls in position from left to right, g - the same, spravo on the left the Thickness of plaster on wooden surfaces, considering from basis level (a wall, a partition), should be not less than 25 mm. In this case it will not be damaged jarred on to lathing. At the big thickness of plaster the additional preparation consisting in stuffing of nails and opletenii by their wire sometimes is required.

It is impossible to put for once on walls and ceilings thick layers of a solution: they will slip, and to burst at drying. It is possible to put an izvestkovogipsovyj solution on slopes and zaglushiny in window and door, apertures a layer in the thickness to 50 mm.

Obryzg - the first layer plaster nameta. Its thickness should be not less than 5 and no more 9 mm. smetanoobraznoj consistences put a solution nabrasyvaniem a continuous layer, without admissions. Its appointment - to fill all roughnesses, and at wooden surfaces - to get under target dran and to be hooked for it.

the Ground - the second layer plaster nameta, put on obryzg after it shvatyvanija or easy hardening. A solution testoobraznyj. It is the basic plaster coat. Put it in one, two or more layers that depends on a demanded thickness of plaster. Each layer level, especially carefully - last on which (as soon as the ground slightly will seize) the thin layer nakryvki will be put.

Drawing kelmoj a solution on a ceiling: and - through a head, - over itself, in - from itself Nakryvka - the third layer smetanoobraznogo a solution in the thickness of 2-4 mm. It put on a ground which should be well levelled. If a ground dry, it necessarily moisten with water from a brush, and on a damp ground put nakryvku. However it is better to put nakryvku on a ground which has already seized, but has not dried up yet. It provides the strongest coupling nakryvki with a ground. The thickness nakryvki depends on flatness of a ground. A solution for nakryvki same by what the ground was carried out; only it is desirable to prepare it on the small sand sifted through a fine sieve with the size of cells 1,5 h 1,5 mm. Such nakryvka it is purely rubbed clean and at colouring allows to do without shpatlevanija.

If the solution was izvestkovo-plaster nakryvku it is expedient to prepare from a limy solution without plaster addition as at zatirke plaster often otmolazhivaetsja and nakryvka has no necessary durability.

solution Drawing on a wall a scoop from the falcon-ladle: and - a scoop, - the falcon-ladle, in - position of a scoop in a hand, g - namazyvanie a solution a scoop As soon as nakryvka will seize, start to zatirke. Dried up nakryvku moisten from a brush with water and rub clean.

Drawing of a solution plaster kelmoj from the falcon. the Prepared solution type (impose) on the falcon plaster kelmoj. For this purpose the falcon one end opirajut on a box, the second end lift at an angle 25-30 ° over a box and kelmoj quickly type on the falcon a portion of a solution (2-4), put in order it, i.e. Remove from edges surpluses to warn solution losses at its transferring from a box to a packing place. At solution drawing on a wall the falcon should be inclined to a wall. Then the hand, holding the falcon, will be protected from hit on it of a solution. A solution from the falcon type the right edge or the end kelmy. Kelmu with a solution bring to a wall, by a hand brush do a wave kelmoj with a sharp stop, thus the solution flies on a surface. However too strongly to wave a hand it is impossible, as the solution will be sprayed. To put a solution it is necessary at different levels, from left to right and from right to left. Correct position of the case of the worker reduces its fatigue and raises labour productivity (fig. 55).

Plastering ceilings, it is necessary to put a solution from different positions from itself, over itself and through a shoulder (fig. 56).

If it is impossible to buy or make plaster kelmu it is possible to make the elementary scoop and the falcon with sides (fig. 57). A solution put the same as and kelmoj. A scoop produce from a roofing steel or duralumin in the thickness to 1 mm. A scoop it is possible not only to throw, but also to smear a solution.
