YOUR FIRST PIECE OF DRYWALL SHOULD BE SECURE Put the first fresh sheet of drywall up against the wall, on top of the spacer board, and so forth. Applying a 2-inch drywall screw to the stud will now hold the drywall in place. (To install the screws, a drill is required.)

Continue screwing each stud at a distance of six inches. Make sure your screws are 1 inch or less from the drywall panel’s edge.

GO ON UNTIL THE ROOM IS COMPLETE. Finish the rest of the room using the same method, but remember to leave about an inch between drywall panels.

To make cuts for electrical outlets and switches, use a utility knife. Additionally, where complete drywall panels won’t fit into the available space, cuts will need to be made.

You must move the studs and mark your spacer board again when you reach a new wall.
