Sheetrock Ceiling Repair

Sheetrock is the modern answer to old-fashioned plaster walls and ceilings. Unlike plaster, which you spread on wet and allow to dry to form the surface, Sheetrock comes in sheets that you use to form the wall. You cover just the seams between the sheets in plaster. One advantage to Sheetrock is that if something damages it, that damage is usually along the seams rather than the board itself, since the board consists of gypsum, which is more flexible than plaster and usually won't crack. Clear out the furniture and cover the floor before you start the repair.

Instructions

    • 1

      Use a 6-inch drywall knife to scrape off all the existing plaster from the damaged seam. Pull off the existing tape, exposing the seam completely. Scrape off any residual plaster. Expose and clean up the whole seam, even if only part of the seam has damage.

    • 2

      Press mesh adhesive tape over the seam, covering the entire length of it. Press the tape to the ceiling with the palm of your hand to ensure that it's flat.

    • 3

      Spread joint compound over the tape from one end to the other, using the 6-inch drywall knife. The line of compound should be slightly wider than the tape, so it covers the tape completely. Ensure that the surface of the compound is flat and smooth.

    • 4

      Allow the compound to set for five or six hours. Use the drywall knife to scrape off any ridges or peaks.

    • 5

      Apply a second coat of joint compound on the seam using your 12-inch knife. Make the seam an inch or two wider on both edges than it was. Let it dry for five or six hours. Scrape off any ridges.

    • 6

      Apply a third layer of joint compound, making it a little wider still along both sides. Let it dry overnight.

    • 7

      Sand the seam with a drywall sanding pad to get it flat and smooth. Repaint the ceiling.
