It is not difficult to assemble a multi-level plasterboard ceiling on your own. It is enough to have a little experience and perform all the stages of installation sequentially. But you should immediately warn that the lower ceiling levels are marked on a leveled surface. Therefore, if the height of the ceiling in the room is insufficient for leveling with plasterboard, you may have to leave the main ceiling as the top level, having previously straightened it with plaster or putty.
First, you need to remove the old paint or whitewash from the ceiling. If the panels were glued, then they must be removed and the ceiling surface cleaned from traces of glue. If there was a stretch ceiling, then it is disassembled, all fasteners and other elements are removed. if the original base of the ceiling is curved, a single-level ceiling must be pre-assembled.
The markup begins with a horizontal mark. For this, a laser level is used. You can use the water one, but the laser is more convenient and faster.
The device must be placed in the center of the room, turned on and wait until the beam calms down. The laser is then directed one at a time to the corners of the room and marks are made on each of the converging walls.
According to the risks received, horizontal lines are beaten off with the help of a paint cord. It is pulled tight between the corners, then pulled slightly from the wall and released to produce cotton. As a result, a clear mark is left on the wall. To obtain a basic horizontal, this operation must be repeated along all the walls.
Since the first level is leveling, it should be as close to the main ceiling as possible. To determine its location, it is necessary to find the lowest angle, for which the distance from the ceiling to the base horizontal is measured. Where it is the smallest, there will be the desired angle.
Now, to get the ceiling line of the first level, you need:
- set aside in the corner found from the ceiling 4-5 cm (thickness of the PP profile plus a gap of 1-2 cm);
- measure the distance from the base horizontal to the mark made on the converging walls;
- postpone this distance in the remaining corners;
- connect the received marks, beating off the lines with a paint cord.
Next, you need to outline the attachment points of the ceiling profiles. For this:
- on the ceiling along the long wall, marks are placed with a pitch of 400-600 mm. The markup should start from the shortest wall in the room;
- marking is made on the second, parallel to the wall, starting from the same side as in the previous step;
- as a result of joining the marks, parallel lines are obtained, along which the fixation points of the suspensions are marked with a step of 700 mm.
The hangers are installed perpendicular to the lines using wedge anchors.
When installing a multi-level ceiling, the step between the intermediate frame profiles of the first tier should not exceed 400 mm, since it will carry an additional load. In addition, such a step makes it possible to install additional embedded inserts for securing the structure of the second tier.
The next step is to install the ceiling profiles. They are inserted into the wall profile guides and attached to the hangers. In order for the lower edges of all PP-profiles to be in the same horizontal plane, you can stretch the fishing line or use a rule-rail. In this case, intermediate profiles are set first, which will act as beacons. The remaining PP profiles are already aligned with them.
Stiffeners are attached perpendicular to the mounted profiles with crabs. A PP profile is also used for them. Stiffeners should be located at the site of the planned joints of drywall sheets. The necessary information on how to correctly and quickly work with the profile.
At the same stage, embedded profiles are installed under the frame of the second level, since it cannot be attached directly to drywall. Embeds are installed according to the drawing, in pre-designated places.
On this, the frame of the first tier is ready and it can be sewn up with plasterboard sheets. In this case, a frame element must be located under each joint. By the way, there are important tips on how to avoid the appearance of cracks on the ceiling from the gypsum board.

Installation of the second and subsequent levels
The required height is laid on the walls from the upper tier, and the guide profiles are fixed. In this case, it is necessary to take into account the thickness of the drywall sheet.
According to the existing drawing on the sheets of drywall of the upper level, the outline of the lower one is marked. Along these lines, pre-prepared blanks from the PN profile are attached. For straight sections - just segments of the required length. For curved ones - the profile must be cut and bent to the desired shape. Stiffeners are also installed between the guides.
Now the side walls of the second tier box are being manufactured. For this, strips of the required width are cut from drywall, taking into account the thickness of the gypsum board. These strips are fixed to the already set contour. They are attached to their free edge from the inside with self-tapping screws PN-profiles, which, in turn, are connected to wall guides with additional profiles.
The lower level frame is ready. It is sewn up with plasterboard in the same way as the upper tier.
Subsequent levels are performed in the sequence described above. The following video will show in more detail the technology for assembling a two-level ceiling. In order to find out how much material is required for the ceiling, use the online calculator, it will help you to purchase the required amount of material. Further video examples to help.
