How to Repair Fine Popcorn Ceiling Cracks


Deep cracks in a popcorn ceiling can be very challenging and expensive to fix, but fine cracks are easily mended. Although you may have to repeat the repair with changing weather, the process is not difficult. With the right supplies and precautionary steps, you can ensure safety and quality in your repairs.

Things You'll Need

  • Latex or acrylic caulk
  • Caulk gun
  • Water
  • Paper towel
  • Scissors
  • Step stool or ladder
  • Cut an opening 1/4" wide on a tube of latex or acrylic caulk and insert the caulk into a dispensing caulk gun.

  • Stand on a step stool or ladder so that you can comfortably reach the fine ceiling crack that needs repair.

  • Slowly insert the caulk into the crack while using your finger to follow along with the tip of the caulk gun. Manipulate the caulk so that it fills the fine crack.

  • Wipe off any extra caulk from the ceiling with a dry paper towel.

  • Dampen another paper towel and use it to wipe any remaining caulk residue that isn't located within the crack.

  • Allow the caulk to dry for 24 hours before applying a coat of primer sealer paint.

  • Once the primer has fully dried, apply a layer of latex paint over the repaired area.

Tips & Warnings

  • Some older popcorn ceilings may contain asbestos, a dangerous building material. Use caution by wearing a face mask and latex gloves when repairing any cracks.
  • The ceiling may be susceptible to cracking as the weather changes. Simply follow these steps to repair in the same manner.
