For decorative plasters (knitting substances, the fillers painting substances (pigments), acid are necessary for etching).
As knitting materials apply colour portlandtsement (brown, red, pink yellow, blue, green, black colours) and white portlandtsement. When instead of colour cement use usual, choose its most light tones.
Fillers for such plasters - quartz sand a stone crumb of rocks (marble, a limestone granite), mica, anthracite, beaten glass, rubble and gravel.
Mica and beaten glass add to a decorative solution in a small amount for reception of crystal shine.
Rubble and gravel apply to creation of the type-setting invoice.
Dry painting substances (pigments) use for solution colouring. Apply minium iron, ohru, graphite, soot, manganese dioxide, umbru, a mummy and their mixes more often. Besides, for colouring or solution clarification add powder from white and colour stone breeds.
Acid hydrochloric (technical) 5-10%-s' is necessary for etching of cement plasters.
Now on sale there are plasters ready to application, and also the dry plaster mixes of different function, allowing to reach high-quality and reliable furnish of the house. .
First of all, before plaster a surface check on a deviation from a horizontal or vertical plane (define by proveshivanija). .
For this purpose in a wall corner, is closer to a ceiling, drive in a nail 1 ( rice: 2 and ) for a thickness of plaster. From a nail hat lower a plumb to a floor and drive in below a nail 2 so that its hat almost concerned a cord. If a wall above 3 m, drive in an intermediate nail. Similarly proveshivajut an opposite corner of a wall, driving in nails 3 and 4. After that on nails pull cords 5 and 6 and by means of other cord 7 together define deviations in a wall. .
If a wall surface equal the hammered nails leave in it. In cases when the cord concerns a surface, in these parts it cut down. If it is impossible to make it, in the same row partially pull out from a wall nails (1-2 or 3-4) that in convex place to receive plaster of the necessary thickness. In those places of a wall where there are deepenings and the plaster coat should be thicker, it is necessary for fixing by means of a metal grid or wire weaving. Further on hats of nails pull cords, and on cords drive in through 1,5-2,5 m nails 8-18. On hats of these nails do marks of the plaster test or a usual plaster solution that on them to establish a rule. After shvatyvanija the plaster test or a solution blow of a hammer a rule remove. Thus on a wall there is a strip of a solution (beacon).
Similarly proveshivajut ceilings. Nails hammer on ceiling corners, position of hats of nails check water level or by means of a level ( fig. 2 6 ). .
For maintenance of strong coupling of a plaster layer with the basis the surface should be well prepared. From it delete pollution and create on it a roughness.
The Spadework depends on properties and surface type. .
New concrete surfaces . If they are rough enough, them clear of a dust and washes out water. At an insufficient roughness them notch by means of a chisel, buchardy, trojanki, zubchatki or an axe. These tools put strokes in length of 10-15 mm and depth of 3-5 mm. On rough surfaces the solution well keeps. The polluted places on a concrete surface clear metal brushes.
