Over the past ten years, the technology of plaster has not undergone significant changes. If something fundamentally new has appeared, then perhaps the modern kneading stations, as well as the solution supply. But they can be used only with large volumes of work. Cement-lime mortar for plaster is used today very widely. And the process of its application and subsequent alignment has its own subtleties and complexities.
The walls are aligned with beacons, this is necessary to create a surface of perfect quality - in office, residential, as well as other premises. During such work, metal beacons are first installed on the walls using a level. The lighthouse has a guiding function, and upon completion of work it is dismantled. After fixing it, you can proceed directly to the surface finish. Cement-lime mortar can be applied by spreading or spreading. Its surpluses are removed by the rule and a level rail - in this way the surface is leveled.
Wall plastering, in which cement-lime mortar is used, is an improved type of finishing work. Less time is needed here, however, irregularities are observed with a calculation of 3 mm at 2 m in height. The solution can be poured with a trowel or, in the case of large volumes, can be supplied from the hose of the plaster station. Surpluses are removed by lighthouses according to the same rules.
Cement-lime can be superimposed with a layer, the thickness of which depends on the initial bumps in the range of 2-4 cm. Grinding is considered to be the finishing stage. Felt or polyurethane graters are used here.
In the modern market, plaster solutions are available in a wide range. They are made on the basis of Portland cement, gypsum, lime, cement polymeric materials, etc. So you can choose for every taste and budget. However, despite the fact that nowadays gypsum-based compositions are considered very popular, quite a lot of finishers still use cement-lime mortar. Why is this happening with such a large and convenient choice and reasonable prices? The fact is that the cement-lime mortar has many positive characteristics, and its main trump card is a much more affordable price when compared with gypsum compositions for plaster. Another important advantage is the strength of the material and the convenience of working with it.
To better understand the reasons for using cement-lime mortar, you need to list all its advantages:
- low price;
- ductility;
- high adhesion - the ability to adhere to the surface;
- bactericidal properties;
- optimal humidity in the room;
- high resistance to cracks.
It is clear that any foreman will buy a gypsum mixture to facilitate the work. However, the customer should consider whether it is worth overpaying for formulations that are similar in properties to cheaper counterparts? It is better to save money, and then spend it on something more necessary, since any repair work requires considerable costs.
