Install the corner bead. Using a corner-bead crimper, install the corner bead on the
exterior corners of corner posts. Use nails if necessary.
(2) Finishing Sheetrock The finishing process consists of covering nailheads and covering
seams (covering seams is also referred to as finishing joints). Finish sheetrock as follows:
Check for improperly recessed nails by running the edge of a sheetrock knife over the
nailheads. A clicking sound indicates a nail needing to be recessed.
Use a 4-inch knife and mud pan with joint compound to apply a smooth coat of joint
compound over the nails. Remove any excess compound.
Use the knife and mud pan to apply a heavy coat of joint compound over a sheetrock
joint, horizontal or vertical. A heavy coat is enough to ensure a good bond between
the tape and sheetrock and to fill in tapered edges. Measure and cut the tape to the
length required for a joint (see Figure 2-31). Keeping the tape centered over the joint,
start at one end of the joint and work toward the opposite end. Using the knife,
press the tape into the compound, removing all excess compound. Work off all
excess joint compound, being careful not to wrinkle the tape or leave air bubbles.
Continue to tape all the joints in the same manner.
