Installation of the first and preparation of the second level of the ceiling
Now it’s time to create the first level of the ceiling. To do this, cut off fragments of drywall of the required size. The joints of these fragments should be in the middle of the profiles. Then you need to fix the cut off the drywall sheets on profiles using self -tapping screws. During installation, it is necessary to take care of the output of wires for lamps.
Next, you need to mark the setting of the second tier of the ceiling. To do this, attach the profile of the sd by the edge to the surface of the wall and make a mark on the wall. Using the level, you need to draw a line at the marked height around the entire perimeter of the room, and on the ceiling to outline the contours of the transition of the second to the first tier.
