  2. Remove 8” (20 cm) of release backing and position exposed tape surface on cleaned seam area. Expose 8” (20 cm) of tape at a time by pulling release backing away from mastic as tape is wrapped around the entire circumference of the manhole, vault, or pipe.
  3. Carefully cut the Boa-Tape™ when applying over cast iron manhole gussets. Gently mold the tape around gussets with a roller or gloved hand.
