    1. Measure the area where drywall will be installed


    2. Mark measurements on the back (gray) side of drywall


    3. Place T-square along marked line for straight cuts


    4. Score deeply through paper and into gypsum with utility knife


    5. Flip sheet over and fold along scored line to crack gypsum core

    šŸ’” Pro Tips

  • Score multiple passes with light pressure rather than one heavy pass
  • Use a drywall rasp to fine-tune cuts that are slightly too big
  • Save cutout pieces for patching small holes later

  • āŒ Common Mistakes to Avoid

  • Trying to cut through entire thickness in one pass
  • Measuring from wrong reference point
  • Not accounting for electrical box depth when cutting outlets

  • šŸ” Troubleshooting

    Rough, torn edges

    *Cause:* Dull knife blade or rushing cut

    *Fix:* Use sharp blade and score multiple light passes


    Piece too small for opening

    *Cause:* Measurement error

    *Fix:* Use joint compound to fill small gaps, or cut new piece


    Can't break cleanly along score

    *Cause:* Insufficient scoring depth

    *Fix:* Score deeper, ensuring cut penetrates gypsum core
