Plaster board is one of the most common type of walls. Cracks in plaster board, which is a gypsum plaster centre bonded to layers of fiberboard, can be repaired with a special drywall repair tape and plaster. Cracks can be caused by shifting and settling of a building, or by the holes made to hang pictures or fixtures. The process of patching a crack in plaster board actually first makes the crack deeper and wider, which looks distressing, but results in a more satisfactory repair.
