Once you have cut more than half of the board, turn the knife over and cut from the bottom of the board to finish the cut.

Step 4: Break the Gypsum in the Core

Pick up the sheet slightly, bend it gently and a little knock from your knee will break the gypsum along this line. The paper on the back of the board will still be intact holding the board together.

  • Outline layout with the sheets lying flat on floor rather than standing on edge. It’ll be easier to use straight edges and simple chalk lines.
  • You have to cut openings for existing doors and windows before you hang the drywall sheets
  • Peeking jambs and insulation prevent cutting of the sheets in place. Make the cuts while the sheets are standing against the stack instead of piled over the opening. It’s helpful to have another person help and support the sheet to prevent cracking while you cut, especially if the cutout requires narrow, fragile drywall legs on either side of the opening.
  • Save wastes by firstly cutting pieces to length before cutting to width.
  • Use 12-ft. long sheets instead of 8-ft if you can manage the pieces and struggle them into the room. The remaining pieces will be longer, so they’re probably more useful, and you’ll have fewer joints to tape and fix.
  • As much as possible, minimize the number of joints, especially hard-to-tape butt joints.
