Do a physical inspection of every joint before signing off on concealment. Run your finger along the mastic joint — it should be continuous, fully adhered, and bridging the joint. Gaps and voids are rework, not acceptable.
Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
