Fiberglass-mesh tape is easier to use, as it doesn’t have to be embedded in joint compound like paper tape. It can be applied to the drywall first, then covered with compound. Fiberglass-mesh tape is good for tapered joints and patching holes, but it is tough to use in corners. Self-adhesive fiberglass-mesh tape can be pressed into place quickly.
Both types can be cut with the edge of a taping knife, trowel or a utility knife.
