External plaster And decorative solutions (ch. 2)

"ртрэр " plaster is formed by processing of an obverse surface by a glass strip. Prepare a solution and put it on a surface the same as and for usual plasters. But in a solution, except to exhaust, white cement and sand there should be a gravel krupnostju grains of 4-8 mm (the invoice "Ётрэющ" plasters depends from krupnosti grains). Then a strip has flown down in the thickness of 6-7 mm in the size 300X100 mm conduct on a surface of fresh crude plaster from below upwards. Glass clings to separate grains of gravel, pulls out and stretches them. As a result on plaster vertical fragmentary strips of different depth are formed.

Terrazitovye create plasters after the preparatory layer will harden on all surface. Before drawing of a decorative layer a finished surface plentifully moisten with water. To put a finishing layer it is necessary at one time on the area limited rustami or any other elements - pilasters, window apertures etc.

The Solution put on a surface in the usual way for two-three receptions depending on a thickness nakryvochnogo a layer and level poluterkom. After that to plaster allow to dry out within approximately 24 hours (depending on air temperature) to such condition when the top layer at zatirke starts to be showered. Then start definitive furnish of a plastered surface - tsiklevke. For this purpose use a special grater - a board in the size 150X150 mm and thickness 20X25 mm into which in chessboard order on distance of 15 mm are from each other hammered the nails acting on 10-15 mm. This grater from top to down pass on a surface of an obverse layer therefore small deepenings from getting enough sleep gravel and separate sites of a solution are formed. Terrazitovuju plaster do continuous on all surface or with rustami (fig. 19), cutting a facade on separate sites. In this case separate defects of an obverse layer are less appreciable.

For achievement of the big decorative effect at oshtukaturivanii window and door slopes on perimetre of apertures on a facade do frameworks of a solution in the thickness of 2-2,5 sm which then paint in white colour.

Kamnevidnye of plaster simulate buchardirovannuju the invoice of a granite, marble, etc. materials.

One of the most widespread is plaster "яюф уЁрэш=" which within long years keeps the initial decorative properties.

Work on drawing of decorative plaster conduct in such sequence: on the dried up, preliminary moistened preparatory layer with a notch for the best coupling put smetanoobraznyj a cement mortal in the thickness 1 - 2 mm; after that at once put a decorative solution in the thickness of 5-8 mm. The mix should be moist. Such mix impose kelmoj on a surface and level. To clear the top layers of a crumb and cement traces, a surface wash out water by means of a manual spray (sprayer). Then, for invoice reception "яюф сѕёрЁфѕ" it condense with special punching in the size 150X150 mm from bronze or stainless steel with a relief surface in the form of acting pyramidal teeths (as at a hammer for otbivki meat). After drying of an obverse layer in a current of 3-4 days a surface wash out a ten-percentage solution of hydrochloric acid, and then water.

As well as terrazitovaja, plaster "яюф уЁрэш=" can be smooth on all surface and rustovannoj. Rusty allow to execute a finishing layer without visible joints.

For cutting rustov it is possible to use the special adaptation consisting from fastened among themselves two equal reek in length of 2-2,5 m, with a gleam between them in width of 10-12 mm. The adaptation put to a surface of a wall and a cutting torch or masterkom cut out rust. Then, having moved apart rejki upwards and downwards, mow down sides rusta. Rusty in the form of narrow deepenings fill iron strips. In the beginning a surface by means of a cord and a ruler break under the drawing into stones or it is simple on squares, having designated their thin protsarapannymi lines (stuffing carry out on svezhenanesennoj to plaster). To the planned line put a steel strip in the thickness of 5-15 mm and the length equal to the party of a stone or a square, and hammer blow deepen it in a plaster coat on 5-10 mm. Then a ruler edges rustov cautiously take out so that not to tear.

Plaster "яюф ьЁрьюЁ" carry out in the same way, only at solution manufacturing use a white marble crumb and white cement. Adding pigments, it is possible to receive colour furnish of an obverse surface.
