How to Repair a Sagging Ceiling

The Process

• 1

  Lay a plastic sheet or tarp on the floor underneath the area of the ceiling you are trying to fix to catch any paint or plaster that falls.

• 2

  Use plaster washers to patch, tighten and stabilize any loose ceiling plaster. Plaster washers are made of tiny metal discs that have 4-inch drywall screws fastened to the ends.

• 3

  Use a sander made of mesh to remove the paint from the damaged area and make it smooth. Secure the sagging ceiling by reattaching it to the attic floor joists with wall panels. Do this by following the seams, pushing the drywall in place and driving nails through it.

• 4

  Apply primer to the ceiling to stop water stains, if any, from seeping through the repaired ceiling. Wait for the primer to dry.

• 5

  Make a thin mixture of drywall compound. Use a paint roller to apply the compound to the repaired ceiling. Apply paint to the repaired area.
