With its help easily identify areas where the old plaster has started to peel away from the wall – this is necessary to completely recapture, because their presence will lead to the inevitable formation of cracks in newly plastered wall.
The next stage of training is the identification and elimination of foci of reproduction of fungi (molds). Action here will require radical, even if the old plaster is held firmly, it must be completely (to masonry) to remove from the wall. After that, you will need treatment with special antifungal composition, preferably twice. After drying, the entire surface of the wall should be treated with acrylic primer of deep penetration – if the wall is loose and easily crumbles, it is necessary to ground a in 2-3 layers with intermediate drying each for 1.5-2 hours.
In some cases, when you need plastering walls with gypsum plaster, but the old plaster layer is still quite durable, and painted with alkyd enamel, a task seriously complicated, because to fully remove the paint will be incredibly difficult. In this case there is a simpler way to handle the wall with primer «Beton-contact», which is a suspension of quartz sand in an acrylic binder. After drying, the surface of the wall reaches the desired roughness, which will be easy to keep the new layer of plaster.

It guides galvanized steel/aluminium that allow you to create a uniform layer of plaster, and greatly simplify and speed up the work process.
Beacons are precut at the height of the wall. Then, starting from one of the corners of the room begins the process of their installation. It is easier to do with the use of alabaster (hardening time which is 5-7 minutes). Alabaster spankings applied to the wall (2-3 places), after which it is pressed vertically into the lighthouse and is aligned to the level of construction so that was strictly vertical. The preferred use of 2-meter level. The next lighthouse is set on the distance from the first, what length is used the rule. Beginners will be easier to work with rule with the length of 1-1,5 meters.
Once all the beacons are installed, issues like plastering on beacons plaster plaster almost does not occur, because the further process is quite simple. Cooked pounces on the wall of the building with a bucket of suitable size from bottom to top. After having closed the wall surface height of about one meter, rule plaster layer to be trimmed (also, starting from the bottom) – the very rule, while sliding over the beacons. The result is a fairly smooth layer, and in the formation of small pits, you can fill them with a spatula.
If necessary, the dried surface you can start to wipe the plastic or steel trowel, soaking it in the water. Thus, with sufficient skill it is possible to obtain an almost perfect, glossy surface. Thus, the question of how to plaster, gypsum plaster, is not so difficult as it might seem at first glance.

However, it is possible to plastering drywall and polystyrene gypsum plaster, and allowed its use is not concrete or brick walls.

It is worth noting that despite this, the plaster reinforced concrete foam polystyrene or desirable to keep with pre-installation of steel or plastic plaster mesh – it will greatly increase the strength of the surface, preventing the formation of cracks in it. It is worth noting the opportunity to plastering of the ceiling plaster at the same time, particularly pleased with the fact that it is possible to apply a thick enough layer in one pass, which will allow to hide serious defects.
