Why exterior wood turns grey
Grey is an appearance change, not a complete condition report.
Read / explore ↗UnderstandWhy weathering looks uneven
Map the pattern before treating the whole surface.
Read / explore ↗UnderstandWeathering and decay are different questions
Surface appearance cannot clear a structural concern.
Read / explore ↗Exposure
Sun, shade and the visible surface
Use site-specific exposure notes rather than a compass label alone.
Read / explore ↗ExposureRain, runoff and splash patterns
Follow the water path before interpreting a mark.
Read / explore ↗ExposureUnder cover is a different exposure
A covered surface is not necessarily an unchanged surface.
Read / explore ↗Observe
Wet colour is not dry colour
Compare surfaces at a consistent visible condition.
Read / explore ↗ObservePhotograph wood so comparisons mean something
Repeat the viewpoint, light and context—not just the subject.
Read / explore ↗ObserveSurface checks and texture: what to record
Describe visible changes without turning them into a safety diagnosis.
Read / explore ↗ObserveA dark mark is not a diagnosis
Appearance alone cannot identify the cause of a stain.
Read / explore ↗ObservePlan a useful sample exposure
A sample can inform a decision without promising the whole project’s outcome.
Read / explore ↗ObserveBuild a seasonal appearance record
A good record preserves change without inventing a cause.
Read / explore ↗Decide
Choose natural greying or a maintained finish
Choose an appearance strategy that includes the work it requires.
Read / explore ↗DecideClear and pigmented finish questions
Ask about the exact finish rather than relying on a category name.
Read / explore ↗DecideNew boards beside weathered boards
A replacement creates a new starting condition in an older setting.
Read / explore ↗DecidePrepare an exterior wood appearance brief
Give the supplier a visual goal and the conditions it must address.
