Internal plastering of walls, indispensable working conditions for
Despite the fact that it will be about finishing works inside the premises where you can afford to forget about the latest weather reports, one should also take into account the fact that not all rooms in these rooms will always have all the conditions inincluding heating. So, the season for applying to the walls of the plaster still have to choose the most suitable for temperature performance. The fact is that internal plastering of walls can be carried out only if the temperature of their surface is not lower than +5 degrees Celsius .Not adhering to this rule will lead to the fact that adhesion( adhesion to the base) of the mixture will be extremely low with all the ensuing consequences.
Plaster is considered the cheapest finishing material, but some "craftsmen" are trying to save even on it. And now the dried layer of plaster, in which lime was not reported, starts to slowly but surely crumble, and from the touch of the hand this process accelerates, leaving distinct marks on the fingers. And all because because of the small amount of the astringent component the composition is "lean".Therefore, take only proven brands in shops that are trustworthy. After finishing the walls with poor-quality plaster it will take you as much time as working with the best mixture, namely, on an average of 1/5 of the labor for repair work. In general, plastering is considered the most laborious process.
Decorative plaster for interior works as the best way of finishing
In general, all grades of decorative plaster are called only by analogy, in general, is a multicomponent paste with excellent adhesion to any surfaces. Of course, this is not a glue, but its viscosity is almost equal to it. However, this consistency is completely independent of the amount of binder, so do not think that by adding a large amount of gypsum or lime you will transfer a simple plaster to the rank of decorative. On the contrary, with such an overabundance of astringent components, the composition will become too "greasy" and will start cracking over time, and then, after falling into the microcracks of moisture, and break down.
Decorative plaster for interior works receives all its characteristics only due to its special components, namely, the content of minerals, silicone, silicates or acrylic in it. Polymers, like acrylic, give the plaster mixture really unique properties. It is these mixtures, in the composition of which there are polymers, that are best suited, for example, for finishing the ceiling. The polymer also includes internal warm plaster, in which there are pellets of expanded polystyrene. Mineral plasters also have only a small percentage of mineral grains, the main binder is white cement.
Internal plaster of the house is a very important task
It's no secret that the plaster is impeccably applied only to a well-cleaned wall, so try to prepare the surface in advance, shortly before the work starts. If the substrate is highly absorbent, it is necessary to primed it with a special compound to improve adhesion, in this you can use a conventional paint brush or roller. Then you can proceed to the preparation of mortar from the dry mix, unless, of course, you have not purchased the finished decorative plaster for interior decoration. The factory mix is diluted with water to the desired consistency of not very liquid dough, to maintain the viscosity of the composition.
The main point is a thorough mixing of the solution, afterwards neither water nor a dry mixture in the solution can not be added.
The walls and ceiling of the plaster should be started immediately and, if possible, used up the amount cooked within half an hour. Of course, there are mixtures that harden very long, but they begin to grasp for about forty minutes. On the ceiling, decorative, including Venetian plaster is applied by a falcon in the direction of itself, and on the wall the mixture can be applied with a trowel or plaster falcon, as it is convenient for anyone, but with movement from the bottom up. Leveling is performed in zigzag motions. If these simple rules are observed, the internal plaster of the house will be made by you without any complications.
