How to Repair a Ceiling Crack

Cracks in ceilings are caused mostly by settling of the house and the expansion and contraction created during that settling.

To repair a crack in a ceiling:

  • Score the crack with a utility knife to remove any loose plaster or other material that may be inside the crack.
  • Use mesh tape to cover the crack. This will allow the mud to bond directly to the plaster which will make the repair stronger.
  • If your ceiling is drywall, you may have to add some screws to hold the two halves in place and make the crack even on both sides.
  • Apply joint compound over the taped crack.
  • Once the joint compound is dry, sand the ceiling smooth.
  • Prime and paint the ceiling.
