To putty drywall

To do this, the first thing is also marking the beams, drawing two parallel lines on the ceiling, the distance between which will be equal to the width of the future structure. Then a 28×27 mm profile is attached to them, to whose side the side pieces of drywall are screwed the desired width. The same profiles are also attached to the lowering of these sheets (from the inside of the beam). To ensure the stiffness of the structure between these two guides, vertical racks are attached. For the same purpose, horizontal jumpers between the lower profiles are also made, which are attached to the walls and this guide. Then the lower part of the decorative beam is screwed, after which you can proceed to putty drywall.
