Over the past ten years, plaster technology has not changed significantly. If something fundamentally new appeared, then perhaps modern kneading stations, as well as supplying the solution. But they can only be used for large volumes of work. Cement-lime mortar for plaster is used very widely in our time. And the process of its application and subsequent alignment has its own subtleties and difficulties.
The walls are aligned with beacons, this is necessary to create a surface of perfect quality - in office, residential, and other premises. When carrying out such work, metal beacons are first installed on the walls using a level. The lighthouse performs 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 bysmearing or pouring. Its excess is removed with a rule and an even rail - in this way the surface is leveled.
Wall plastering, which uses cement-lime mortar, is an improved type of finishing work. Less time is needed here, however, irregularities are observed with the calculation of 3 mm per 2 m of height. The solution can be thrown with a trowel or, in the case of large volumes, supplied from the hose of the plastering station. Surplus is withdrawn by beacons according to the same rules.
Cement-lime can be applied in a layer, the thickness of which depends on the initial irregularities in the range of 2-4 cm. Grinding is considered the final stage of finishing. Felt or polyurethane graters are used here.
In today's market, plaster solutions are offered in a wide range. They are made on the basis of Portland cement, gypsum, lime, binder polymeric materials, etc. So you can choose for every taste and budget. However, despite the fact that gypsum-based compositions are considered very popular in our time, quite a few 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 plaster compositions. Other important advantages are the strength of the material and the convenience of working with it.
To better understand the reasons for usingcement-lime mortar, you need to list all its advantages:
– low price;
– plasticity;
– high adhesion – ability to stick to the surface;
– bactericidal properties;
– optimal indoor humidity;
– high crack resistance.
It is quite clear that any foreman will buy a plaster mixture to facilitate the work. However, the customer should think about whether it is worth overpaying for compounds that are similar in properties to cheaper counterparts? After all, it is better to save money, and then spend it on something more necessary, since any repair work requires a lot of money.
