How to Fix Drywall Buckle


Drywall is an effective covering for interior walls. The wall boards are screwed or nailed to the studs,and then taped and covered with compound to give you a smooth or textured look. Over time, depending on the moisture level and settling of your house, you may notice that the drywall has become buckled or uneven. With only a few tools, a day or two of your time and a few techniques, you can give your uneven drywall a brand new look.

Things You'll Need

  • 12-inch drywall knife
  • 6-Inch drywall knife
  • drywall pan
  • drywall tape
  • drop cloths
  • flat screwdriver
  • Phillips screwdriver
  • 1-1/2-inch drywall screws
  • Hammer
  • Drywall compound
  • Sanding screens
  • Lay out your drop cloths in the work area to protect the floor. Remove any receptacle and switch covers with your flat screwdriver, and store them in a secure spot.

  • Open your drywall compound, scoop it out and place it into your drywall pan with a 6-inch drywall knife. Fill the pan about 3/4 full with compound.

  • Locate any screws that are not flush, and run them to just below the surface of the drywall with your Phillips' screwdriver. Remove or tap flush and nails sticking out of your wall with the hammer.

  • Locate any areas not properly secured to the wall. Run drywall screws through the drywall and into the stud beneath with your Phillips screwdriver to secure the drywall and remove any waves.

  • Skim over any nails, screws and empty holes with drywall compound and your 6-inch drywall knife. Scoop up a small amount on your 6-inch knife, hold it at a 30-degree angle to the wall and press the compound into the hole or indention. Scrape off any excess compound on your knife onto your pan. Hold the knife at a 70-degree angle to the wall, and scrape off any excess compound on the wall.

  • Skim over any larger holes and joints with your 12-inch drywall knife. Hold your 12-inch knife at a 30- degree angle to the wall, and place a light coat of compound onto the wall. Place drywall tape on top of the wet compound, and slide your clean 12-inch knife over the tape pressing it into the compound. This action will also remove any excess compound.

  • Allow all of the drywall compound to dry completely, and skim all areas with compound again. Allow the second coat to dry completely and lightly sand all areas. Your drywall buckle is now repaired and ready for paint.

Tips & Warnings

  • Be careful when repairing water-damaged walls. Walls contain conduit and wiring which conducts electricity. Electrical shock hazard is present in this situation. If electrical sockets or switches are present on a wall being repaired, please shut off and lock out electricity to that room.
