Do the repair of high quality!
If the ceiling in your room is uneven, since the shrinkage of reinforced concrete slabs took place unevenly, then you can dashcat the ceiling or make it lining with the help of modern finishing materials as dry plaster, drywall or wood -steering plate. You can also use suspended or suspended ceilings — they will not only correct the irregularities of the ceiling, but also optimize the lighting of this room.
