The matter is that internal premises of inhabited and public buildings for some reasons should be repaired with change of colour of walls. And to change a tonality of colour plasters difficultly.

Color izvestkovo-sandy solutions prepare in rastvorosmesitele. At first fill in the liquid limy dough, then fall asleep cement. Mix 1... 2мин, fall asleep sand and mix even 3 minutes After that enter painting material (a pigment and a part to exhaust), preliminary ground in kraskoterke.

Color izvestkovo-sandy solutions prepare also from dry mixes, factory fabricated. Put them on a ground from a limy solution (sometimes with the small additive of cement) after ground hardening (on 6... 7th day).

The Thickness of a decorative layer depends on size of grains napolnitelja.

The Decorative layer can be left smooth or to give it various structure - for this purpose there is variety of ways.

Drawing nakryvochnogo a layer nabryzgom. On a finished plane with in advance put thin layer colour nakryvki nabryzgivajut some more layers. If the solution taken for this purpose has fine-grained structure nabryzg make with shchetinnoj brushes (fig. 60). the Brush immerse in a liquid solution, bring to a wall and spend on hair a ruler. Splashes fall on. A surface also give it a shagreen leather kind. Nabryzg make in some layers, allowing previous to seize.

To receive the medium-grained invoice, take a solution with sand of average krupnosti. Nabryzg conduct from a broom, impose a solution in some layers and lead up the general thickness to 8... 10 mm.

The Coarse-grained invoice nabryzgivajut through a grid with cells Z. 10мм depending on krupnosti napolnitelej a solution. Put a solution too in some layers till the thickness nabryzga 8... 10 mm. For nabryzga different layers it is impossible to change distance of a grid from a wall - it should be to constants - nearby 15 see

Nabryzg is conducted by flakes differently. At first put on a plane nakryvochnyi a layer of dark colour in the thickness about 6 mm. It diligently rub clean and at once throw a layer of a light solution. Make it by means of a metal broom and put flakes so that between them the dark basis appeared through.

Flakes of larger size (nabryzg throws) make a plaster shovel from the falcon. It is necessary to watch, that throws were identical and laid down one near another.

The Various invoice can be received, processing trimmed surfaces different tools on a plastic solution and a solution semihardened.

The Invoice "яюф =ЁртхЁ=шэ". Over the prepared wall throw a colour solution in the thickness of a layer of 10 mm. A fresh solution nadirajut a metal broom, moving it in a horizontal direction. After that a surface slightly smooth a metal shovel, moving it too across.

The Invoice "яюф трыѕэ№". Svezhenanesennyj a colour solution level poluterkom and tortsujut rigid hair or shchetinnymi brushes (fig. 61).

The Invoice "яюф уѕсъѕ". Put a layer smetanoobraznogo a colour solution, level poluterkom and tortsujut a surface a sponge. That the solution did not litter and did not stick to a sponge, it is necessary to moisten it in soap water and to wring out.

Color plastic testoobraznomu to a solution, having levelled it poluterkom, it is possible to give the invoice "яюф сюЁючф№". Do it by means of special malok with the semicircular oblique teeths of various size cut out on them. Malki conduct on directing rulers. Furrowed structure receive also, processing a fresh layer shtkatur gvozdevymi brushes.

Furnish of facades of buildings various rustami too spend more often on a fresh not strong plaster coat. Cutting of seams-tapes do the most various: horizontal and vertical, narrow and wide (fig. 62). Difficult rusty extend templates (fig. 62, in and. less difficult fill the steel ruler, which thickness 8... 10, width 40... 50 and length 500... 800 mm. For reception of seams of rectangular section a ruler put to marking lines, tap on it with a hammer, deepening on the set depth. Then a ruler cautiously take out (fig. 62,). Rusty in width 1... 2см cut rustovkoj, moving it on the enclosed ruler.

the Device rustov on a building facade: and - a steel ruler; - tsiklej; in - a template (vytjagivanie two tapes); g - a template (vytjagivanie one tape)

Thin rusty cut in already painted plaster. For this purpose use a scrap of a saw in the size 20... 30 sm, placed in a wooden holder (fig. 62, 6).

It is possible to do rusty by means of supplementary smooth wooden reek trapezoid section. Depending on the set depth rusta rejku put on the marked surface - on a ground or nakryvochnyj a layer. Space between rejkami fill with a solution which level and condense.

After shvatyvanija a solution rejki cautiously take out, rusty clear away. A body especially deep rustov form bricklaying ledges.

On a fresh finishing layer carry out both the so-called type-setting and combined invoices. In svezhenanesennuju plaster press various small stones: a pebble, splinters of rocks, brick shchebenku. Usually so finish rustovannye stones. When the set will be fixed, do obryzg by a colour solution in the thickness no more than 10 mm.

Combined name the invoice which turns out at use of various ways of furnish. For example, on a finishing layer various furrows, and then nabryzgivajut smetanoobraznyj a solution from a brush cut, a broom or through a grid.

On the semihardened solution izvestkovo-sandy plasters including colour, rub clean, scrape, do a small notch.

Rub clean to receive a smooth surface, measured spiraleobraznymi movements (zatirka round) or movements of a grater identical on length (zatirka vrazgonku).

Surfaces with granular structure "яюф яхёёрэшъ" Well look;. For this purpose through 1,5... 2ч after drawing of a solution of a surface scrape. TSiklja (fig. 63) removes a film from knitting materials and tears out any quantity of grains of sand. The received rough plane clear a soft dry brush or a brush.
