Measure the ceiling and cut drywall sheets to fit
Mark ceiling joist locations on the walls and drywall edges
Lift the first sheet into place with a drywall lift or helpers
Position the sheet perpendicular to the joists
Leave a small gap around the room perimeter
Fasten the drywall to the joists with drywall screws
Start screws near the center of the sheet and work outward
Space screws about 12 inches apart on ceilings
Keep screw heads slightly below the surface without breaking the paper
Stagger end joints between adjacent sheets
Cut openings for lights, vents, and fixtures before hanging
Use T-braces or temporary supports if needed
Hang remaining sheets tightly but without forcing them
Tape and mud the seams after all sheets are installed
Sand the joints smooth after the compound dries
