While fiberglass mesh tape is stronger than paper tape in expansion under ultimate tensile load, it does not reinforce the joint compound in compression, bending or shear, and will allow visible cracking of the joint compound to occur at lower loads as the glass mesh stretches. The only time USG recommends mesh tape is when you’re using our fiberglass drywall tapes with USG setting-type joint compounds.
USG Imperial® Tape Type P has an open weave that provides excellent keying of plaster during embedding. Strong, glass-fiber tape for joint reinforcement in USG veneer plaster systems on wood framing.
