VERT / GREEN
Measurements use a documented method tied to the applicable product/drawing.
Flatness, level, plumb and square before finishes
Measure substrate before cabinetry, tile, glass, doors or panels; do not use a universal tolerance out of context.
JAUNE / YELLOW
A small framing error can become a large correction when rigid finishes arrive.
ROUGE / RED
If substrate exceeds product/spec/professional requirements, correct it before installation rather than forcing the finish.
Checkpoint before proceeding
What the professional checks
Finish trade and substrate-responsible party agree on measurement method and applicable criteria before installation.
