This PVC-coated section needs a field cut for the revised route. I checked the coating system, but the edge-repair procedure is not in the field package. Can we get the approved method before cutting?
Watch out
Do not treat PVC-coated duct like bare galvanized sheet or patch it with ordinary duct mastic.
Check
Identify the coating system and service environment.
Check the manufacturer and project requirements for cut edges and holes.
Plan the cut to avoid unnecessary coating damage.
Verify cure and inspection requirements before concealment.
