Although you could use paper drywall joint tape and drywall mud, the repair is easier using a fiberglass mesh adhesive backed joint tape. I like it because it is stronger than paper tape and does not require drywall mud bedding.
- Cut lengths of the fiberglass mesh tape and adhere to the joints of the patch.
- Make sure to cover each length of seam with its own continuous piece of tape.
- Overlap the corner joints.
