2" x 500' Circle Brand Fiberglass Joint Tape T3001
Circle fiberglass mesh tape is used to prevent cracking at butt joints (where two drywall sheets meet). It is used on all butt joints and inside corners, then mortar is applied. This specific marking tape is self-adhesive, so you don't need to apply a layer of mortar beforehand; you can simply apply it directly to your drywall.
Self-adhesive drywall sealing tape significantly increases strength and durability to reduce cracks and leaks on the job site. No coating is required.
