Repairing Drywall Cracks That Keep Coming Back
Let’s say that you’ve already tried to fix a couple of the drywall cracks in your home, but you’ve noticed that they keep returning. The drywall keeps cracking in the same spot for some reason. With a bit of careful analysis and some hard work, you should be able to mend the cracks so that they won’t appear again, or at least not for a while.
What To Do First: Place Drywall Tape on the Crack
First, apply strips of drywall tape to the crack. Usually, one side of the fiberglass drywall tape is already sticky. If not, use some of the drywall compounds like glue to help the tape adhere to the wall.
The Next Step: Add Joint Compound to the Crack
Once you’ve placed the drywall tape, spread some of the drywall mud or joint compound over the tape in a thin layer. You want just enough to help the tape adhere. Let that dry for a bit, and then start spackling in earnest. Start at the center of the tape and spread the spackling compound or drywall mud outward and downward for the first layer.
Drywall Cracks That Keep Coming Back Due to Serious Problems
Unfortunately, some drywall cracks aren’t just there because of normal settling or seasonal temperature changes. Sometimes, a crack in a drywall ceiling that keeps coming back could be due to a failing beam or a moisture issue.

Prepare the Opening
Trim the edges of the hole to create straight sides and a square or rectangular overall shape. Use a framing square and a pencil to mark cutting lines on the drywall. Then cut along the lines with a drywall saw.
Warning
Make sure there is no wiring or plumbing behind the drywall surface before cutting by looking through the hole with a flashlight.
Install the Backing Strips
Cut two pieces of lumber or plywood a few inches longer than the long sides of the hole (if it's a rectangle). Place one piece into the hole, parallel to one of the long sides, so the strip is centered over the drywall edge (half is behind the drywall and half is exposed).
Install the Drywall Patch
Cut a piece of drywall to fit the hole. It doesn't have to be a snug fit, but the seams should be not more than about 1/8 inch wide. Position the patch over the hole and secure it to the backing strips with screws. Keep the screws about 1 inch from the edges of the patch and space them 6 inches apart.
Tape the Seams
Cut strips to length of drywall joint tape using a utility knife. Cover each seam with a strip of joint tape. Overlap the tape strips at the corners. Make sure the tape lies flat, with no wrinkles or bulges.
Mud the Seams
Cover the drywall tape with a thin layer of drywall joint compound, using a 6-inch drywall knife. You should be able to see the mesh through the compound. Let the compound dry. Then scrape the surface with the knife to remove any burrs or clumps.
