What to Check First
- Make a clean square cut
- Remove loose fibers and debris
- Verify the approved edge-coating product
- Treat exposed edges, seams, and penetrations as specified
- Inspect after fittings, access doors, or sensors are installed
Ask Foreman
What approved edge treatment are we using on these field-cut liner edges and penetrations?
Do Not Do This
Do not leave raw liner edges exposed, use random paint or sealant, or cover loose fibers without cleaning them first.
Why This Matters
Untreated edges can erode, shed fibers, absorb moisture, and fail inspection.
Verify against: liner manufacturer instructions, project insulation specification, approved product data.
