Plaster plaster is on sale in the form of dry loose mix. Ready structures are stored in hermetically closed buckets. They can differ with the characteristics depending on availability and type of the used additives.
One of labor-intensive processes at repair is the otshtukaturivaniye of walls. The plaster blend is often applied to this work. It differs in plasticity, durability, simplicity in work. After such processing the surface becomes smooth.
The main component of solution is plaster. It is natural material which does not contain harmful components. Therefore solution is safe for health. It does not shrink, quickly stiffens and dries. If on ready layer water accidentally gets, it will not affect quality of covering. This material is resistant to fungus and mold, allows to create comfortable microclimate indoors.
Ease of mechanical damages, higher price in comparison with other types of plaster belongs to shortcomings. It is impossible to apply it and in the presence of open metal goods. In the latter case finishing material will cause corrosion.
How to choose plaster to plaster?
At first it is necessary to be defined what fractions of filler suit you. There are three views:
- Fine-grained. Add the ground sand to them. Such types can crack if to apply mix with thick layer. Therefore it has to be no more than 5-8 mm. Such version is used generally for ceilings.
- Medium-grained. The most popular type. Admissible thickness of layer – 50 mm.
- Coarse-grained. Are necessary for finishing of surfaces which have serious defects, for example, differences on level or holes. Is suitable for finishing of facades, repair of the broken slopes.
Plaster plaster is applied generally to internal works in the dry heated rooms. Producers constantly improve structures, raising moisture resistance indicators. Depending on features of the repaired room, mix with additives is chosen.
Polymeric additives increase adhesion of material, its elasticity. Similar types differ in the increased durability and frost resistance therefore are applied to alignment of concrete, silicate and other facades.
Mineral additives do plaster stronger, flexible and resistant to adverse atmospheric factors. Such version is considered more reliable and durable.
How to choose the brand?
The huge range of this material is presented at the construction market. Technical characteristics have to meet standards and standards. Such products are turned out under the following brands:
- There are options for manual and machine works, alignment and production of decorative surface. It is possible to buy solution of white or gray color. With its help it is possible to create easily relief panels or volume decor.
- KNAUF Rotband. It is often used by professionals. The period of hardening of mix in open capacity – is 20-25 minutes universal material, but. Because of the last it is not recommended to part it in large number at once.
- Thickness of the put layer can vary from 3 to 80 mm. It is made by the Osnovit company. Important advantage is the long viability of solution. It keeps the properties for 90 minutes.
- "Pro plaster". Such mix is ideal for the beginning masters. Differs in high plasticity that provides convenience of drawing and simplicity of alignment. In structure there is microfibre because of which the surface develops additional strength. The plasticity remains for 40 minutes.
Features of cultivation and putting plaster plaster.
Before works it is necessary to prepare solution. Powder is filled up in dry container. Water is added gradually. That the structure has turned out qualitative, it is necessary to observe the recipe specified on packing. As a rule, on 3 kg of mix 1.8 l of water are required.
It is the best of all to make mixture by means of electric drill. It will allow to receive uniform consistence in which there are no lumps. Ready mix has to remind dense sour cream. It is necessary to give to ready plaster to stand. It is the best of all to use solution as soon as possible.
It is necessary to apply mix on the walls which are in advance moistened with water. Preparation is carried out by means of spray or special brush. On the uvlazhenny basis by means of trowel the dense layer of solution snatches. It is impossible to do too thick layer at once, in the course of drying it will fall in the return case under weight of curb weight.
Solution has to be evenly applied therefore after preparation of walls lighthouses are established. For removal the surplus of mix by the rule is carried out over lighthouses.
At the correct drawing as a result of such work all roughnesses will be hidden under solution. For receiving ideally smooth basis the surface is rubbed clean and polished. It is the best of all to get to such work in about 30 minutes. It is possible to determine readiness of plaster by method of trial cutting. If the tool does not cut, and pulls, then it is better to wait a little more.
For receiving glossy surface of walls in a day plaster is moistened with water and processed the palette until the necessary result is received.
In conclusion we will note: when finishing walls from blocks or brick it is necessary to apply special grid to plaster reinforcing. It is especially relevant for new houses which still can shrink. The lighthouses established in the course of work are removed. It is easy to hide the available grooves under plaster. Such approach allows to receive monolithic covering without metal.
