Drywall
Attaching drywall to a ceiling is the most difficult part of replacing drywall. This is because sheets of drywall are heavy, making it difficult to lift the drywall and position it. However, installing drywall on the ceiling is also the most important step in the process because the ceiling is done before the walls. Putting drywall in the corners of your ceiling is not much different than installing it in the middle of the ceiling. If the corners of the room are square, this makes the job even easier.
Instructions
1. Measure 3 feet along one wall from the corner in which you will be installing drywall, and make a mark. Go back to the corner and measure 4 feet from the corner along the other wall and make a mark. Measure across the corner from one mark to the other. If the distance between the two marks equals 5 feet, the corner is square.
2. If the corner is not square, lift a piece of drywall up to the corner and determine the edge or edges where you will need to cut off some drywall to make the sheet fit better. Lower the drywall and make the appropriate cuts, using a drywall saw.
3. Place a tube of construction adhesive in a caulk gun. Cut off the tip of the adhesive tube with a utility knife. Apply a bead of construction adhesive to the ceiling joists in the corner of the room. Do not be stingy with the adhesive, since it will help prevent sagging.
4. Lift the drywall up to the corner. Lightly mark on the underside of the drywall where the ceiling studs are. Push the drywall against the glue-coated studs and attach it using drywall screws spaced 7 to 9 inches apart. Do not put screws closer than 1/2 inch to the edge of the drywall. Make sure the heads of the screws are slightly embedded in the drywall.
