Paint fails at an entryway faster than anywhere else on a building, because it is the wet part of a dry elevation. Two years in it starts to lift, and the operator has a defect with no record of who applied it or what they applied. Without that the only move is to repaint and hope, with the same specification as before, because nobody knows the first one was wrong for the exposure. In the twin, the finish sits on the surface that carries it, with the contractor, the date and the warranty term against it.
The paint at the entryway is peeling and the question is who did it. The surface answers with the contractor who applied it, the month it went on, and a two year workmanship warranty that ran out four months ago. The copilot adds what the timing suggests: peeling at an entryway two years in usually means the substrate was never primed for the moisture load it sits in — a workmanship argument rather than a wear one, and a failure mode the next specification has to survive.
