Cracks that keep on happening in your drywall occur because of a repair in which the old plaster used to fix the drywall couldn't hold onto the drywall behind it. To get plaster to hold onto your drywall surface, you must thoroughly clean the surface and also mix your plaster or joint compound correctly according to the manufacturer's instructions. You must also apply a caulking solution before reapplying the plaster to seal the gaps in the crack, especially you can fit your pinky finger inside the crack, or if the crack is even bigger than that. Use joint compound for the most effective drywall repairs.

  1. 1

    Remove all the loose pieces and bits inside the crack. Do not be alarmed if this procedure increases the size of the crack.

  2. 2

    Use a spray bottle filled with water to spray the remaining plaster. Spray once and wait about 30 seconds to let the plaster absorb the water. Keep doing this until you see water dripping. Leave the wall alone for about five minutes.

  3. 3

    Apply some caulk with your gun in the crack, moving from the very top to the bottom. Smooth out the caulk with your finger once you've finished.

  4. 4

    Mix the joint compound according to the manufacturer's instructions.

  5. 5

    Put some transparent tape along the crack and skim the joint compound around the crack with a float. Let the compound dry for at least 30 minutes before you apply a second coat, if necessary.

  6. 6

    Sand the compound with 120-grit sandpaper once it's dried. Wait at least 24 hours, if not more, before you prime and paint the surface.
