Ideal corners and absolutely plain surface of walls can be received, using gypsum cardboard. But not all agree to concede to this finishing material the modest living spaces. By means of gypsum plaster and own efforts it is possible to achieve quite good results. Walls are recommended to be leveled not only under painting, but also and under wall-paper. Finishing finishing of walls repeatedly wins if to make it on the prepared plain surface. Not seldom it is necessary to observe how through beautiful expensive wall-paper look through badly processed walls, especially it is noticeable on light thin wall-paper. And over wall-paper, crookedly pasted ceiling plinths, wavy adjoin to wall and create shadow at artificial lighting. At least, it looks ridiculously therefore before painting walls and to glue on them wall-paper, it is necessary to level vertical surfaces. Within this article we will consider option of alignment of walls in the panel house.
What it is required to us for alignment of walls?
Buckets, basins and rags will be in each house. Besides on alignment of walls it will be necessary for performance of work for us:
- quick-hardening gypsum plaster for filling of explicit deepenings and correction of big curvature of external corners;
- gypsum plaster of high quality, for finishing of walls under painting – basic gray and finishing white;
- the roller, the sprayer or brush for putting primer;
- wide stopping knifes it is not less than 2 pieces; angular palette; palette scraper;
- trowel or trowel;
- pravlo or semi-graters;
- grater or the holder for abrasive paper;
- abrasive paper 0;
- emery bar;
- nozzle mixer on drill;
- measured capacity for water;
- blade or scoop for gypsum plaster;
- perforated corners.
Basic and finishing putty get that which hardens, not too quickly, it is difficult not for experienced person to use quickly prepared mixes. All finishing material (mixes, primer) is the best of all to choose from one producer. The quantity of perforated corners has to match quantity of corners which you are going to govern. It means that corners in the subsequent will remain in solution cavity.
Preparation of walls
Before beginning to level walls, it is necessary to remove from them finishing material (wall-paper, painting, ceiling and floor plinth), i.e. to peel to plate by means of palettes. Old wall-paper is removed better if previously to moisten them with water. For compactness scraps of wall-paper are put at each other and turned in rolls which fix by adhesive tape.
After the surface of walls is released, it is necessary to process them by means of sandpaper, i.e. it is necessary to remove all strongly acting hillocks. In corners use the angular palette. The sticking-out armature needs to be removed too. The most uneven places on walls of panel houses, as a rule, in corners, under ceiling and near floor. Think whether you will be able to remove excess thickness on all perimeter? To level the main area of wall to it it is problematic, it is too much work therefore it will be more reasonable to make soft junctions between the main part of wall and top bottom. After on wall there are pasted wall-paper or it will be painted, this difference will not be noticeable.
After full cleaning of walls it is necessary to remove from them all dust with broom or the vacuum cleaner. Not superfluous will be to wash them with any cleaning agent.
Further it is necessary to apply primer on all surface. The main works can be begun after primer drying.
If on walls there are explicit deepenings and big cracks them it is necessary to close up quick-hardening mix. Try to level surface of “patches” at once. After partially closed up places completely dry up (time of drying is specified on packaging with mix), apply on them primer. Further it is possible to start the main works.
Begin to level walls, i.e. to apply solution from floor. For this purpose mix gypsum plaster with water in the recommended proportions. The compounding needs to be observed, otherwise too liquid solution will flow down, it is bad to keep on walls, and when drying such surface will be all in small holes from the burst air bubbles. Too dense mix will stiffen earlier, than you will manage to level it.
Capacity in which you will make mixture has to be rather wide that it was more convenient to pick up mix on trowel or the palette.
Carrying out plaster of walls, it is necessary to master the main movement: outline of solution on wall. Do it with force as though you want to hammer mix into wall surface, then it will well stick and you will only need to level it. Experienced masters are able to outline solution trowel which scoop mix. For the beginner this process not such idle time therefore it is more appropriate to use the same trowel and the palette or it is possible to use such method still: the palette on trowel to put solution, then the same palette to take gradually mixes and to outline on wall. Everyone outlines solution in own way therefore be defined as it is more convenient to you to do it. Having applied, thus, solution on surface about 1 sq.m, level this area grater. Level solution with circular motions. Continue to do batches, you apply plaster and level surface to ceiling.
If in some places the wall has the wavy form, then fill only low sites until you make even them crests.
You apply plaster on the layer thickness on which it is intended. Do not try to plaster all area for one layer, it is not done even by professionals.
When drawing basic layer it is not obligatory to level it ideally, you will apply on it not less than 1 more layer.
It is impossible to add new portion of gypsum plaster or water to already prepared solution. All prepared solution needs to be used at once. If at you remains superfluous, then remove it from capacity before hardening at once, later it will be to make is problematic.
Some complexity is represented by alignment of internal and external corners. But this moment is very important because carelessly executed corners nullify all efforts on alignment of walls and at the same time are capable to hide all available flaws.
We govern corners
Internal and external corners can be leveled by means of perforated corners.
The internal corner needs to be leveled so: on all height of corner to apply quick-hardening mix with intervals in 15 – 25 cm and to fix on it perforated corner. Before fixing it is necessary to define, where the biggest hollows and hillocks and, proceeding from it, to try to fix corner exactly. Solution before hardening needs to be distributed on all corner and to leave before full drying. Later the put time it is necessary to continue to equal corner, having left it in corner cavity (i.e. it is not necessary to delete corner) finishing or starting putty depending on that how many layers you will do.
The external corner is carried out in this way, only the perforated corner is put on the contrary. In case of big curvature of corner, it is necessary to put several layers of solution before full alignment.
After you have caused enough plaster coats and consider that you wall quite equal, execute grinding of all surface. It becomes by means of grater or the holder for abrasive paper. Before painting or pasting of walls wall-paper apply on them primer.
It is possible to clean tools from the stuck plaster by means of the small palette, at the same time it is not obligatory to polish every time the tool till glitters at all, it is possible to lower it in capacity with water to the next day.
Having executed plastering of walls, you thereby considerably will raise their sound insulation. Having established in the apartment new outer doors with sound insulation, plastic windows, of course, it is possible to achieve considerable decrease in penetration of noise from the street and from site. But it is not all measures which are necessary for ensuring the smallest penetration of noise from neighbors. To isolate the apartment from neighbors, it is necessary to fill in floors, in several layers to plaster ceiling. But the most important it is necessary to think over arrangement of electric sockets well. They mostly are also noise conductors between apartments.
