- Excessive solutions are removed by the rule. The hand with the rule should go smoothly and zigzag, so as not to form irregularities;
- Formed voids are filled with plaster, and its surplus is removed by the rule.
Actions must be repeated until the wall becomes smooth and smooth. After that, the beacons are removed, and the appeared shoes are neatly filled with gypsum plaster. Lighthouses can not be removed if the tile will be laid out on top of the finish.
With a large irregularity of the base, the pumping and smoothing of the mixture is performed in several goals. Each layer must dry well. After drying, the final surface of the walls is sanded and prepared for applying the final finishes: painting, pastries with wallpaper, laying tiles, etc.

- ease of use.
When complying with the technology of application, the surface is obtained smooth and smooth. Due to this, the subsequent painting or pasting wallpaper will be perfect.
