Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check
Access-door leaks are not just “more mastic.” Check the frame, gasket, door seating, and latches first.
Field checklist
- Confirm the access door is the right size/type.
- Check frame is seated and fastened.
- Inspect gasket and latch contact.
- Seal frame perimeter only as approved.
- Make sure the door still opens and closes.
