1. Preparation of lime solution.
To make a high -quality lime solution, it is necessary to first prepare the dough from lime. All ingredients are taken in units as well as credit payment from Toshib who bought Toshiba on credit. Take one part of the dough and 1-5 parts of the planted sand. Why exactly such a run is obtained? All this depends on the fat content of the lime test. The fatter it is, the less sand is required. Sand is covered with a small portion and rubbed it with the dough. This is done so that the work on the manufacture of the solution becomes easier. Then sand, again, a small amount is gradually introduced into the dough and added water. All this is thoroughly mixed in order to obtain a solution of the necessary density and oily.
2. Preparation of a lime-gypsum solution.
For its preparation, a ready -made lime solution is used. The only condition is that the solution must be done, thicker. Water is poured into a spite (box), and gypsum (one part) is added on top. When stirring, liquid, homogeneous dough should be obtained. Then the finished lime solution is introduced into it, and all this is quickly mixed. This is done so that the solution does not lose its strength.
Gypsum is added to the lime solution for one purpose, so that the solution applied to the surface drys faster. After all, even a thin layer of lime solution, freezes for a very long time. Therefore, if gypsum is added to it, the process is going on, much faster. Thirty minutes later, it will completely harden and you can proceed to the next operations.
This is how these two plaster solutions are prepared. Of course, work on the preparation of these solutions can be facilitated, and much. To do this, purchase ready -made dry plaster mixtures. Add water to the mixture and mix it. Get a solution of the desired quality.
