PVC-Coated Duct Is Cut Without a Coating-Repair Plan

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?

Stop if

Stop before changing structural support, rated construction, equipment handling, specialty materials, weatherproofing, engineered movement details, or manufacturer-specific requirements without the responsible direction.

Watch out

Do not treat PVC-coated duct like bare galvanized sheet or patch it with ordinary duct mastic.

Check

current drawings and approved details
grid/floor/location and measured conditions
photos showing the installation condition
relevant manufacturer, structural, architectural, or finish information
what has already been checked
