What is plaster, know many. It is the finishing giving to the building a complete look, serving for protection of designs against adverse effects, prolonging construction service life. It is possible to entrust its performance to plasterers pros, but even the beginner can do plaster of walls the hands.
Practice and knowledge of some bases is for this purpose necessary. And the skill comes with experience. For what plaster is necessary? How to make plaster of walls in a new building? What is necessary for plaster of walls? We will try to answer questions, important for the beginner, here.
For what it is necessary to plaster walls in the apartment
Even an interior in style the loft – only imitation by plaster under concrete of the raw wall surfaces. Plaster of walls in the apartment solves in a complex many problems.
Plaster covering:
strengthens a bricklaying;
protects concrete, gas-concrete surfaces from penetration of dampness from air;
prevents formations of fungal or mouldy defeat;
protects wood from cracking, rotting, insects, rodents;
levels uneven surfaces of walls, ceilings;
serves as additional heater;
absorbs noise;
creates a comfortable microclimate in the apartment;
omonolichivat the internal surface of the room of the apartment, sealing seams and joints of designs;
protects wood from ignition;
protects structures of the building from external influence;
levels surfaces according to state standards therefore facing by a tile or gypsum cardboard, pasting by wall-paper, painting is facilitated.
To change a wall or a partition more expensive, than to change, or to repair plaster vestments. Modern plaster structures please with durability, – service life reaches 25 and more years. Plastering of walls of the house at the same time resolves many problems.
Main types of plaster
As construction material and as a type of finishing plaster structures is known from antiquity. The antique Latin name – styuk, stukko remained till our time.
Further the speech will be about plaster for internal finishing of walls.
Finishing solutions happen:
decorative,
usual,
special.
Ordinary structures are applied to draft plaster of walls and ceilings, an omonolichivaniye of joints.
Depending on quality of performance of a surface plaster finishing happens:
high-quality – finishing of walls readily under painting or a sticker of wall-paper, is carried out obryzgy, multilayered putting soil and the finishing nakryvka;
improved – for utility rooms in houses and also, for draft finishing, consists of three layers – an obryzg, soil (the main layer), the nakryvka leveled by the rule and jammed by a gladilka;
the plain plaster consisting of two layers – an obryzg and soil, is applied without proveshivaniye, filled up with a polutyorok, applied to plastering of cellars, warehouses, utility rooms.
The decorative structures differing in texture and color apply to finishing finishing which does not need wall-paper, facing or coloring. Special plaster structures apply to performance of certain tasks. For example, they are used for additional thermal insulation of the apartment (heat-insulating plaster), by protection against the ionizing iatrotechnics beams (barytic plaster), treatments of crude walls of the house (sanifying).
Functional additives are a part of plaster solutions water (or solvent) and also the binding, making bases, fillers. As the main components of plaster structures are the knitting substances after hardening becoming similar to a stone or plastic, plaster structures classify by the form bases.
Further we will consider usual plasters
Cement
From the name it is clear that the main knitting substance of this look is cement. The simplest plaster structure – cement and sand. Finishing is strong, frost-resistant, inexpensive. It suits for internal and street plaster works. Perhaps manual or mechanical drawing. On sale is available in the form of dry mixes (CC) which part the modifying additives are. Solution can be prepared by the hands independently.
It is cement limy
Lime as substance to plastering began to be applied long before the invention of cement. Plaster limy solutions of a vysokoplastichna. Using this quality, lime is applied as additional binding in cement and limy solutions.
Perhaps manual drawing or the mechanized plastering. The structure is trained independently, or buy ready dry plaster mix. It is applied to draft and decorative finishing. Is suitable for finishing of wooden surfaces.
Plaster
The natural material which is easily stacked, plastic. More expensively than the previous plaster mixes, however has the advantages. Plaster structures carry out high-quality plaster of walls of rooms with normal humidity. CC are issued also decorative. Drawing manual and mechanized. It is good for foam concrete.
Clay
Natural knitting, applied not only in rural houses. Clay is eco-friendly, promotes maintenance of a favorable microclimate in the house. The clay plaster covering can be put with hands. Waste practically does not happen. Even the dried solution can be wetted, mixed and applied on the basis again. It is maintainable.
Decorative
This type of plaster materials is most various. CC and ready solutions make many companies, both Russian, and Italian, French, German and others. Are issued on mineral, acrylic, silicate, silicone, polymeric bases. Distinguish impressive, structural, color, kameshkovy, terrazitovy structures.

What mix it is the best of all to perform works
The choice of mix for plastering depends on several factors:
basis material;
appointments (technical for alignment or finishing);
degrees of roughness of the basis (big or small differences);
requirements of resistance to the damp environment (the increased or normal humidity);
service conditions (whether chemically aggressive Wednesday, temperature condition);
strength characteristics (speed of set of durability and brand);
difficulties of performance of plaster work (can be decisive for beginners or in case of geometrically difficult surface).
If plaster of walls is planned by the hands, then those that stick to the basis better more are suitable for the beginner, keep within easier, have the big term of life and quickly gain durability.
Plasterers pros recommend plaster finishing. It is easily put, formed, quickly hardens.

What ways of drawing exist
Depending on the size of the plastered surface and also the entering components ways of putting plaster can be:
manual (trowel, roller, trowel, ladle or just hands);
mechanized (with use of a hopper, plaster cars).
The choice of a way of drawing is often dictated by what plaster coat can be put for pass. When working manually some types of mixes put with a layer up to 6 cm thick. Mechanical drawing is limited to creation of a layer up to 20 mm.
Among manual ways of plaster of walls distinguish ways of drawing:
the technical (leveling) finishing with use of beacons or without them;
decorative (drawing by various tools, formation of a surface different receptions) finishings.
Manual drawing
Plaster of walls the hands consists in putting solution on the basis a hand tool, leveling, smoothing down or formation of an impressive surface for one pass or in consecutive creation of a multilayered covering. Manual plaster of walls is usually carried out at the small area of a covering, the general thickness of a layer of alignment to 10 – 12 cm, performance of finishing impressive finishing. At multilayered finishing each layer is dried.
The mechanized drawing
It is rational to use this way of performance of plaster works when there is an optimum combination of speed of plastering, the small cost of materials (a part of means is saved for expensive machine works), the large volume of a covering.
Plaster of walls with use of the plaster car is more economical on:
to expenses of forces;
to the spent time;
to consumption of plaster materials;
to financial expenditure for acquisition of plaster mixes which for machine works are cheaper.
Other pluses:
small volumes of waste;
uniformity of imposing and prize in quality, due to machine control of a ratio of CC – water;
supply of mix on a surface under pressure increases adhesion with the basis;
due to uniformity of mixing and imposing of a layer the general strength characteristics of mechanical finishing are higher, than manual.
Minuses: not always, not everywhere it is applicable
The mechanical equipment for plaster variously on complexity level. Apply small-scale mechanization (hoppers, sprays) or, even, the machine devices which are carrying out a zatvoreniye of plaster mix and drawing it at air supply by the compressor.
Apply mix, holding a nozzle in 20 – 30 cm from a wall, moving a working part of the device along a surface with an identical speed. After completion of work all details adjoining to solution wash out, dry. Use of eye protections is obligatory.
Seal of cracks
New buildings can undergo shrinkage process within one or two years. Plastering of new houses mineral plaster solutions during this period leads to emergence of cracks. Cracks meet also in houses the big term of operation. All cracks need under repair. Special repair is demanded by big cracks. "Heal" such defects with application of the reinforcing grids.
Cracks count up disclosure to 5 mm small. They are allowed to be covered with hard putty or cement, more liquid, than masonry, solution. The average cracks opened up to 10 mm on a surface "treat" TsPS solution (cement and sand), previously having embroidered. Large (more than 10 mm) educations sanify TsPS solution with use of crushed stone and reinforcing.
Solution is tried to be pumped in a crack crack more deeply, using for this purpose the construction syringe. The site of a brick and concrete wall before seal of cracks solution is cleaned from dust, humidified. Over the site with the covered body of a crack impose a piece of a grid which fix to a wall self-tapping screws. Plaster the site over a grid.
as the plaster covering strong keeps if is available;
whether there are exfoliated places (check a prostukivaniye);
whether there are other defects demanding elimination;
walls are how equal (carry out measurements).
General preparation
According to norms, the basis under plastering has to be removed dust, not have the centers of biodefeat, oil and rusty spots, vysol, uninsulated metal parts (brackets, nails, self-tapping screws). The plaster covering has considerable specific weight.
Before plastering of a wall the hands do notches, deepen seams for increase in adhesion. The basis is grounded, then dried up. Besides, preparation includes installation of beacons if plastering is conducted on them.
Priming of walls and installation of beacons
Dismantling of old plaster
If the old plaster covering strong, well keeps on a wall, carry out plaster of walls on old plaster. The covering unnecessary for the subsequent finishing, delete completely. It is required when the old plaster cover is strongly damaged.
Before removal of finishing it is moistened, using a sponge. If under the removed plaster there is a gypsum cardboard, then it is easily tapped. Having tapped also chips partially exfoliated site, unsnap adjacent plaster, getting under it a corner of the pallet or a chisel.
Can be necessary for full dismantling:
Bulgarian;
hatchet;
hammer;
pallet;
puncher;
scraper;
spray;
goggles, respirator.
Necessary tools for dismantling of old plaster
Sequence of actions:
namachivat a plaster covering, give it time (15 – 20 minutes) for a razmokaniye;
the pallet check a condition of friability of a layer;
delete a layer with possible means (the pallet, a chisel, a hatchet, or sawing the Bulgarian finishing on squares with the subsequent breaking off by the puncher with a zubilny nozzle).
Kk the concrete wall prepares
Often inexperienced people have problems at plaster of concrete walls the hands. Such not each plaster solution is well linked to the basis. Before, plaster solution was applied on concrete surfaces without use of primers. Therefore there is a probability that the old covering can disappear from a concrete wall together with new.
That it did not happen, from concrete walls old finishing is removed completely. When the design is bared, also joints of wall panels which were usually just covered superficially open. Hollow joints before an otshutakurivaniye fill with foam.
Zapenivaniye of concrete slabs and drawing notches before plaster
Also, before plastering apply notches up to 3-5 mm in depth on the surface of concrete with a hatchet, a chisel, buchardy or the hammer. For drawing notches sometimes use an easy jackhammer with a nozzle-buchardoy. Roughnesses increase coupling of the dense concrete bases with styuka.
If the electrical wiring is planned in shtroba, then its laying is done before plastering. In advance install fasteners, for example, suspended hooks.
It saves from unnecessary labor input, time and materials in the subsequent.
Preparation of a wooden wall
Wood especially needs preparatory work. Drawing notches is not always rational. Therefore the wooden bases before plastering upholster with shingle – thin reechka not wider than 20 mm. Shingle is beaten on a basis surface, disposing a lath at an angle 45 degrees to a floor, at distance about 4.5 cm from each other.
The first fill a narrow or curve tatter. Atop beat crosswise the second row of a tatter. That levels did not break up in the course of a pribivka, the ends of shingle presoak.
Besides, on the ends of a lath do not beat closely to each other, leaving an interval of 2 - 2.5 mm. Stuffing of nails with a wire interlacing on them helps to do without shingle.
For increase warm and noise isolations of board partitions, boards before attachment of shingle cover with burlap or gunny, lowering woven material before contact with a floor. Having beaten on a bottom, pull and attach the top end.
These materials are well linked to solutions, serve as additional isolation for boards, reduce soaking and buckling of the last. Then the plaster covering cracks less. Edges of fabrics connect with an overlap.
Preparation of a brick wall
In a bricklaying before plastering deepen approximately on centimeter masonry seams. Do it by a chisel, holding the tool at an angle to 45 degrees to a surface along the line of a seam. Bricks clean from pollution with metal brushes. Then the wall is washed.
If after washing with use of detergents fat or pitch spots, vysola appear, process them specifics, or clean mechanically to pure material. After preparation the basis is dried.
Gas concrete, gas-block, foam concrete block
How to prepare walls from these materials? With them, apparently, it is simpler. All speakers of roughness soshlifovyvat the grater intended for a gas concrete or a plane. After removal of dust cover with primer a brush or from the sprayer twice. Between priming dry, giving the chance to be formed to crystals and to fill a near-surface time.
Priming of a wall
Installation of the reinforcing grid
Partitions and walls from foam, gas-blocks do not shine with durability therefore they can burst at the slightest sags of the base. For strengthening the surface is reinforced a grid from fiber glass fabric which attach 2-3 mm on a layer of tiled glue. Glue is smeared with the pallet and stretched a gladilka. Impose glue a strip about a meter wide. Put to it a grid strip, smoothing it from the center of a strip up and a bottom.
Having established a grid, establish beacons. Before plastering over a grid impose the pallet a glue layer, combing it (for increase in adhesion) horizontally gear pallet. Dry up.
Arbolitovy plates
Because of roughness arbolitovy plates are always well linked to plaster finishing. Therefore additional measures are not required. Some plasterers fix on wood concrete the metal gauze for hardening of the wall.
Whitewashing
It is impossible to plaster on limy whitewashing because the covering will strongly not keep. Whitewashing is always multilayered, and plaster is linked only to the top limy plyonochka.
Whitewashing is deleted in several ways:
remove the pallet (a damp laborious way) – sites moisten, in 15 minutes remove sodden lime;
delete with the grinder (minus a way – a lot of dust, it is necessary to work in a respirator and points);
apply paste with a brush a thick layer on whitewashing. After drying the kleysterny crust which fastened with itself limy multilayered lime is deleted with the pallet (the most dust-free way);
wash away soap solution (on a bucket of water of a half-piece of polished soap, 5 tablespoons of soda), repeatedly moistening whitewashing with a sponge or a brush;
wash solutions of acids.
Plaster on colored walls
According to the standard rules paint before plastering should be deleted. However, if business does not concern damp rooms and also styuk with a big body weight, a strong film of paint it is possible not to eliminate. Well the light plaster plaster applied on paint keeps.
Ways of removal of paint:
soaking of 20 minutes with removal by the pallet (for water emulsion);
use of the special softening solutions;
heating and softening by the hair dryer, scraping by the pallet;
removal by a metal brush;
removal with use of mechanical means – grinders, etc.
Preparation of the painted walls for plastering includes:
drawing on the basis of the notches passing through a paint film painted by enamel or oil paint;
removal by the pallet of the exfoliated sites;
removal of a glossy layer nazhdachka or grinder;
removal of dust damp fabric;
degreasing of oil spots solvent;
drying of the prepared basis.
Necessary tools and materials
The list of what will be necessary for plaster:
for solution preparation – capacities, the mixer, a rastvoromeshalka;
for drawing – pallets (simply – a shovel), a bucket, a trowel, a trowel, rollers, brushes;
for extension, leveling – a grater, semi-graters, the rule;
for priming, formation of a relief pattern, coloring: rollers, brushes, brush, sponges, cliches, other make-shifts;
for measurement, a marking, installation of beacons – the level, a plumb, a roulette, a painting adhesive tape, a cord;
for coloring – brushes, a sponge, rollers, a spray;
for protection – glasses, a respirator, gloves, working clothes
From materials will be necessary:
components of plaster structure, CC or ready structures;
water;
primer;
shingle;
beacons;
the reinforcing grid;
attachment parts are expansion bolt shields, self-tapping screws, nails;
Necessary material for plaster
What is plaster on beacons
The technology of plastering of walls of the house includes options:
under a falcon (alignment without rule, approximately);
under the rule (does not allow to achieve easily high flatness of walls);
on beacons (high-quality finishing).
Approximately (without beacons) to plaster a curve wall qualitatively it will not turn out. Therefore the technology of plastering of walls "under a falcon" is applied only in new buildings with the increased quality of walls, or in utility rooms where the quality of a surface is not important.
The beacon – a level which surface serves a guide for the rule movable by the plasterer at leveling of the solution applied on a wall. Beacons make of metal, plastic, a tree or of the solution applied to plastering. Beacons have height regiments 6 – 10 mm, fasten to the basis solution or self-tapping screws.
Installation of mayachny levels is carried out on a plumb or level strictly vertically after priming. At first expose extreme beacons in 30 cm from corners of walls. The surface of levels forms the vertical plane, being guided by which, establish intermediate levels. Distance between levels do less than length of the rule on 20-30 cm. It is more rational to the beginning plasterers to locate beacons with a meter step.
When plastering on beacons mix is applied layer-by-layer until until solution rises over levels. The acting solution weight is cut off the rule which is densely pressed to beacons, moving it in zigzag fashion.
The surplus is removed from the rule a trowel or the pallet and stacked there where mix lacks. As a result the surface of the leveled solution forms the vertical plane. After a mix skhvatyvaniye beacons delete, and the remained flutes fill with plaster solution.
Plaster reinforcing
Mineral plaster structures have no elasticity, and therefore, like natural stone materials, can burst at the slightest motions of the basis and form cracks in the course of curing, for example, if plaster solutions fat. To reduce cracking and their disclosure, plaster is reinforced.
The same is done at repair of big cracks. Application of reinforcing increases finishing durability. Installation of grids is necessary in problem zones, for example, in junctions of the bases from different materials, for example, of a wall from a tree and concrete. Different characteristics of materials cause various behavior them at temperature change or humidity. Therefore, in the field of a joint cracks will be formed.
Grids are applied to reinforcing from:
metal;
plasticity;
fiber glasses;
Material selection and the size of cells of the reinforcing grid depends on the main objective of reinforcing and an installation site. If powerful grids establish for reinforcing of front finishing or creation of a plaster casing for warming plates, then for internal finishings and also where the plaster coat is small, apply plastic or fiber glass grids.
Grids are the hidden structural element located in a body of plaster is closer to a surface. At a big thickness of a plaster covering establish two or more grids. Attaching a grid on a wall or a ceiling, between a grid and the basis leave a gap which is filled with glue or plaster weight. Do it so that around a panel of a grid there were no air bubbles. The grid has to be drowned.
To fix a grid on walls, its panels, pulling, nail up or attach self-tapping screws. The next cloths connect with an overlap. It is important to pull only in order that there was no sagging that the wall did not turn out a curve. Not to draw.
If material of a grid can corrode at chemical reaction, for example, with limy plaster solution, the grid is protected, covering it with asphalt or coal varnish, oil paint, or cement milk with drying.
Solution preparation
Here three options are possible:
mix preparation by mixture of components independently;
cultivation of structure the CC water or thinner;
hashing of the ready plaster test before application (with addition of a small amount of liquid or without it).
If you independently prepare mix from the components acquired separately, then it is necessary to observe the sequence of mixture of the making substances.
TsPS is prepared in the following order:
place loose solids (sand, cement powder, perlite, a stone crumb) in capacity;
mix;
separately prepare liquid (a limy milk, water with softener, etc.);
stirring, gradually pour in liquid in dry mix before achievement of the necessary consistence of solution;
to structure about 5 minutes then once again mix allow "to have a rest" and infuse.
Preparation of dry mixes
If mix is prepared in a rastvoromeshalka, then it is admissible to pour at first in it a part of water, then to add other components. The remained water is added gradually, controlling consistence of the test.
Acquired by CC shut, following instructions of the producer which are in the detailed instruction on packing. Ready mixes in buckets before application also mix to return to structure uniformity. If plaster solution is painted, – it is a high time to add a color.
For some plaster structures there are nuances. For example, perlitovy sand strongly raises dust. It before mixing is moistened. Except knowledge of rules of preparation of the basis, information on how it is correct to apply plaster on walls in what sequence, how many and as it has to dry is required.
How to apply plaster on walls with the hands
It is possible to apply mix with a nakidyvaniye and pasting. Plastering of surfaces turns out in the first way more dense, finishing is stronger linked to a basis. It is possible to cover with structure a ladle, a shovel (trowel) with a steel cloth. Solution is scooped from capacity and a throw goes from the tool to the basis where he lays down and sticks a thick blot - "slap". Smear dough with the pallet, a trowel, a falcon.
The solution imposed on the pallet or a trowel by the auxiliary pallet is transferred to a wall by dab of the set thickness. The plasterer puts the tool with the test to a wall at an acute angle, and conducts it along a wall, reducing a corner in process of transfer of material by the basis. If dab begins on earlier made dab, reception is called "from wet on dry".
If dab begins on the dry place and comes to the end on other dab, reception is called "from dry on wet". Observance of receptions is important for decorative plaster. How to put finishing decorative finishing, it is possible to examine in other section of the website. Further we offer the detailed description of a way of performance of draft finishing on concrete.
For performance improved and performance of high-quality plaster of concrete walls of technology are similar. The first two stages of plaster of walls are similar. Difference only in end.
The first stage – obryzg
Solution mix with consistence is applied to an obryzg at plaster more liquidly. Layer thickness on concrete, a brick, a gas concrete thickness of an obryzgovy covering – 5 mm, for a tree – 9 mm (with a grid).
Step-by-step instruction of performance of an obryzg:
on a shovel or in a bucket we gather solution from capacity and we throw over a wall between beacons;
we do nabrosa, filling with "slaps" the site about 100 - 120 cm high (from below-up);
having covered obryzgy the area between beacons, the pallet we level a little "slaps" that on the site there was no blank space left;
we line a surface of a layer a keen edge of the pallet for increase in adhesion;
we do the same, carrying out obryzg to wall top;
we carry out obryzg the following sites of a wall, we leave to dry.
The second stage – soil
The main (basic) layer put over an obryzg is called soil. For creation of their thick multilayered covering can be a little. For soil cook dough, dense on consistence. For drawing we use pallets and the rule.
Soil performance:
On the wide pallet narrow we impose dough from capacity.
We transfer solution to a wall, slightly pressing it into the drawn grooves of an obryzg.
We remove the mix acting over beacons from below up the rule, pressing it to beacons and shaking in the horizontal direction. The solution removed by the rule is thrown off in capacity or by the pallet it is transferred there where it lacks.
Having carried out by the rule from below up few times, we carry out the rule from top to down. After such conducting solution will not slip on a wall down.
We plaster thus the wall rest.
We wait when solution grabs, we take beacons, we cover with solution the formed channels.
The third stage – a finishing layer a nakryvka
The structure of a nakryvka becomes with the same proportions, as basic. The consistence of solution of normal fat content – less dense, than for soil, and sand undertakes small fraction (up to 1.5 mm). Such mix keeps within easier, it is more plastic. At overwrite forms a smooth surface. The recommended thickness of 1.5 - 2 mm.
Filling of emptiness and drawing finishing layer
Step-by-step management:
If plastering was carried out without removal of poppies, then the nakryvka is applied on yet not dried up soil. The dried-up soil can be moistened with the roller.
Put a nakryvka, leveling it the rule. At the same time solution fills the formed emptiness and small cavities. Surplus of mix removes.
Zatirka of plaster
This stage completing. The smallest errors are eliminated with Zatirka.
Alignment – consolidation of hardly dried up nakryvka surface – a zatirka is carried out by a grater. The tool is not pressed strongly not to pull off the drying-up layer. Carry out smoothing down with circular motions (a zatirka "round"). Only in corners the grater is kept and conducted parallel to a corner. On the towering sites press more, trampling down, on deepenings pressing is reduced.
The surplus of the acting mix gathering at the corner of a grater or a trowel cleans off. The drying-up nakryvka layer is sprayed with water from the spray from time to time or humidified with a soft brush. The zatirka round with use of absolutely small amount of solution is possible
After a zatirka carry out smoothing at once – a zatirka "in a razgonka". Rectilinear vertical movements (up-down) make a clean grater with the rounded-off corners. The grater is pressed with identical effort, without taking away from a surface. Process so a square behind a square (sites about 1 sq.m).
Smoothing down (not obligatory operation) is carried out similar to a zatirka "in a razgonka", it only becomes the rubber, metal or wrapped-up by felt grater. Process a surface twice. Once, driving a gladilka (in one direction) from top to down, the second time – it is horizontal.
Finishing finishing
Why and than to grind plaster? Such procedure is performed to remove the slightest ledges which remained after plastering or a shpatlevaniye if for final finishing of the apartment coloring, or pasting is planned by wall-paper. The paint coat is thin and reveals even the most insignificant flaws. They are eliminated with grinding.
Manually apply a nazhdachka, a grinding grid or grinding bar to grinding. It is enough to process a surface for wall-paper a nazhdachka with grain 60. Under paint repeated grinding by a nazhdachka 120 is necessary. As a result receive the polished surface. After grinding and cleaning of dust plaster of walls the hands can be considered as finished. It is a little data on how carry out corners.
Plaster of corners
The words "pods" and "usenka" will tell nothing to the ignorant person. And meanwhile, it is the professional terms of plasterers designating internal and external corners respectively. The equipment their plastering differs from putting plaster on walls.
The main technicians applied by plasterers:
with use of a profile corner;
with beacons;
with the kontrashulets (punched by the corner having the aluminum basis));
with a serpyanka (a tape grid from fiber glass fabric or synthetics with a sticky layer);
without a kontrashulets.
Kontrashultsa it is possible to use for receiving pods and a usenok.
Step-by-step technology of performance of a corner by means of a kontrashulets:
Cut the punched corners of the necessary length.
On a corner a dense layer impose contact solution (along an internal corner mix is stretched along all length).
The corner is put to a corner, most densely pressed in the most "outstanding" place, then by means of the rule pressed kontrashults so that he got up strictly vertically (check the level or a plumb).
The surplus of mix which is marked out at installation deletes with the pallet. After that mixes give time to stiffen.
After installation the corner by test is leveled with a wall. Shelves of a corner appear at the same time in plaster solution. A corner of a kontrashulets the speaker protects a corner from damages.
Overlaying of contact solution
Installation of a corner
Removal surplus of solution
Performance of an external corner on a profile corner:
Cut profile corners of the necessary length;
On adjacent walls establish beacons (the corner is plastered before performance of work on a wall);
On a corner a dense layer impose contact solution (along an internal corner mix is stretched along all length).
Afterwards impose soil from two parties from a corner to the next beacons (already more thickly).
The corner is put to a corner, press a grid to mix, the help of the rule level solution on beacons on one, then on the second wall.
The surplus of mix removed by the rule the pallet adds there where it is not enough.
The profile corner and grid appear in a plaster layer.
How to check quality of plaster of walls
Accuracy of performance of finishing is checked the rule or a long two-meter lath. When carrying out it along a surface in different situation (horizontally, diagonalno or vertically), deviations from the plane are found visually. In dark time it is possible to check quality of plaster, having directed a small lamp beam parallel to the wall plane. Long shadows will give the acting roughnesses.
Having measured and having compared two diagonals of the room, it is possible to check, whether direct corners of the room. Diagonals have to be equal on length. Distance between parallel walls – identical on all their length. The correctness of performance of a corner can be checked, carrying out lengthways vertically by the square with a length of parties from 50 cm.
The quality of a surface of finishing is defined visually. On it there should not be darkenings or other spots. Shutters of windows, window leaves and doors have to open without hindrances. Sites around sockets, switches and door boxes, on perimeter of a floor have to be equal that laid on levels, a plinth and platbands densely adjoined a wall.
If you were going to make apartment renovation, and you have no experience of a covering of walls plaster the hands, you should not despair. Having studied the stated data, having watched videos, you gained an impression about main types and technicians of plaster works.
Detailed data on plaster structures, on how to apply decorative solutions, can be found on the website. At the address to plasterers, you will know what to pay attention to as works have to be performed for what this or that stage is necessary.
