We establish the solution of the mortar mass in portions of 10 kg.

We start filling the floor from any corner, but so that in the end the work ends near the doorway. We establish the solution of the mortar mass in portions of 10 kg. And we level it with a trowel to remove all the slides and pits, the layer should be 5 cm, we make such a fill along the entire perimeter of the floor. Then we pour another layer of concrete with a thickness of 4-6 cm, level it with a trowel and then smack by the building level so that ultimately the floor had a finished surface without mayor. The time is given to dry concrete 24 hours, and then we eliminate the small cracks that have arisen when dried up with a small spatula.
