Common Causes
Failed prep, coating over an incompatible finish, trapped moisture, heavy sun exposure, shaded mildew-prone walls, and delayed maintenance can all shorten finish life.
What To Check First
Look for water streaks, shiny old finish, peeling patches, dark corners, and areas where decks, gutters, landscaping, or rooflines keep logs wet.
Next Step
Send close photos and one wider wall view before assuming the whole cabin needs another coat.
