摘要:
A mesh-type drywall tape includes a scrim layer of a plurality of lengthwise strands coupled to a plurality of crosswise strands, wherein the scrim layer includes an indexing pattern for indicating a tape edge. To form the indexing pattern, markings are disposed on multiple strands. In one embodiment, the indexing pattern has a v-shaped configuration with diagonal portions that may vary or alternate in shape and color. The indexing pattern repeats itself along the entire length of the tape.
