Drywall repairs are easy. Cut a square or
rectangle around the patch, and attach wood backer around the patch
opening leaving half the wood exposed around the opening. Screw
attach the new drywall around the patch leaving a space of 1/16 to
1/4". Wet the space with water or thinned compound, and use the
ButtTaper tool to create the tapered edge about the patch.
While using a setting compound
the �" tape is unnecessary or use the
�" tape with joint compound.
Alternatively, use drywall as
the backer instead of an OSB board or plywood. Apply a thin layer
of setting compound on the drywall backer and secure it to the old
drywall with 1-5/8" cement board screws. Use the same method for
the new drywall patch, and finish as instructed for butt joints.
For increased speed, use a
heat gun or hair dryer to speed the setting drying between coats.

video showing a repair on this website.
Note: 1-5/8" cement board screws are the
best drywall laminating screws as the nip under the bugle head
of the screw sinks the screw into the drywall. Remove the
screws after the setting compound on the drywall backer sets and
reuse the screws on other patches. Do not use 1-1/4" cement
board screws as they do not bind the boards well.
