Curved walls can add a touch of elegance to a home. Before the standard use of drywall, contractors commonly used plaster, which was spread directly onto curved surfaces. To attach drywall to a curved wall, you'll have to apply different construction techniques than what's done with flat walls. When installing drywall onto a curved wall, use 1/4-inch-thick sheets as opposed to the standard 1/2-inch-thick sheets.

Measure the length of the curved section of wall. Cut a 1/4-inch drywall sheet to fit. If you need to use multiple sheets, cut them short enough that the edges of the different sheets will meet in the middle of a stud.
Hold the first drywall sheet over the end stud of the curved area with the help of an assistant. Drive a drywall screw through the drywall and into the stud in the middle of the board, drilling it deep enough that the head of the screw goes just below the surface of the drywall.
Install screws into the studs every 6 inches above and below the first screw.
Cut a 1-by-2-inch board to fit the height of the curved wall.
Place the 1-by-2 board against the edge of the drywall where it's screwed to the end stud. Screw it to the drywall and the end stud, but place the screws in a different location than the drywall screws that are holding the drywall to the stud.
Spray the drywall where you are bending it with water. Use enough water to get the drywall damp and pliable but not wet enough that it's soaked.
Carefully push the drywall in toward the wall frame, and attach it to the second stud with drywall screws.
Attach the rest of the sheet of drywall to the wall frame, dampening the sheet and screwing it to the studs as you go. If you need another sheet, install it using the same method, but start at the other end stud.
Remove the 1-by-2 board on the edge of the curve.
Place wood putty over the drywall screws and the holes created by the 1-by-2 board. Sand the putty smooth.
Apply joint compound with a 6-inch putty knife to the seams where different drywall sheets meet. Place drywall tape over the joints, and run the putty knife over the tape to press it into the joint compound. Allow the joint compound to dry overnight.
Add another layer of joint compound and drywall tape to the seams, and allow it to dry overnight. Add a third layer of each, and allow it to dry overnight.
