The solution is ready.

The solution is prepared from Portland cement and construction sand (construction sand is usually river, mined from the bottom of the rivers and passes the cleaning) in a ratio of 1: 3. So, we fall asleep into the container cement with sand and mix until smooth in color. Spend more time on this procedure so that the mixture turns out to be homogeneous. If you use the finished mixture, this step can be excluded, since the factory is mixed quite well. Add water from the calculation one and a half to two liters for every 10 kg of the mixture. Next, mix for about five minutes, let the mixture stand for five minutes then then mix again. The solution is ready.
