Third day arranging a room and corridor: building ceilings and leaving walls ready to be painted.
The approach: given the height, the perimeter of the room is traced with a line marker, a plate fixed along the leveled line to support the joists. Joists screwed to the plate around the perimeter, anchored to the ceiling with threaded rods and tied one to the other with nuts.
The plasterboard is screwed against the beams and structure is done!
Then perforated plasterboard tape is taped over the joints, joint filler paste applied on the joints and screw heads. The dried paste is rubbed next day with sand paper to give a good finish. A coat of plaster is given to the walls and ceiling and rubbed again to leave the surface ready for painting.
