Drywall, or sheetrock, is the first thing you need to buy. It is available in sheets of approximately 4 by 8 feet. You need to buy enough to cover an entire room, plus a little extra to allow for mistakes.
Hammer and Nails
You need a hammer and finishing nails, or a nail gun, to attach the sheets of drywall to the wall studs.
Drywall tape is a webbed tape that is applied over the seams between sheets of drywall.
Drywall Compound and Trowel
Drywall compound, or drywall "mud," should be spread evenly over the taped seams with a trowel and smoothed completely flat to hide the seams between sheets of drywall.
Saw or Blade
In order to cut sections of drywall to fit your particular space, you can use either a scoring blade, a circular saw or a drywall saw.
