Definition & Meaning of "drywall tape"

What is "drywall tape"?

Drywall tape is a type of tape used to reinforce joints and seams in drywall installations. It is typically made of either paper or fiberglass mesh and is applied over the seams between drywall panels before being covered with joint compound. The tape helps prevent cracks and improves the durability of the wall. Paper drywall tape is often stronger and smoother, while fiberglass mesh tape is self-adhesive, making it easier to apply. Both types are designed to ensure a clean, seamless finish for drywall surfaces and prevent damage over time.
