Drywall goes by a few names such as gypsum board, wallboard, gyp board, plaster board or Sheetrock® but whatever name you give it, the stuff will need repair at some time. Drywall is a modern building material that comes in large panels (typically 4' by 8') having a gypsum core sandwiched between two heavy paper faces. These paper faces are often made from recycled paper. One face is very smooth and is the surfacing face and the other is more of a kraft paper backing face.
I have tutorials already for you on repairing large holes in drywall and repairing small holes in drywall, but this tutorial deals with more common repairs such as filling dents, repairing drywall joint tape that split or dealing with popping drywall nails.
So lets review ways to fix some pretty common drywall problems you may have around your home.
