Guided evidence worksheet
Material drying: surface improvement versus trapped moisture
Use the same location, depth, instrument and environmental conditions at each reading. Compare surface recovery with concealed layers.
Reasoning guardrail
Separate the routes before choosing a repair.
A surface that feels dry is not proof that the assembly is ready to close or repaint.
- Trigger
- A measurement trend at the same locations is more reliable than color or touch.
- Area
- Materials
- Provenance
- Original explanatory diagram, not a site photograph.
1. Freeze the evidence
What happened first?
2. Competing hypotheses
Record evidence for and against each route.
Surface dried while deeper material remains wet
Airflow improves the finish first while insulation, framing or backing retain moisture.
Evidence that raises fit
Evidence that lowers fit
Notes
Continuing or intermittent moisture source
New water enters between readings and prevents a stable drying trend.
Evidence that raises fit
Evidence that lowers fit
Notes
Measurement method variation
Different locations, depth, temperature or meter mode create an apparent change that is not real drying.
Evidence that raises fit
Evidence that lowers fit
Notes
3. Decision points
Change one condition at a time.
Do readings at fixed surface and depth points decline together over time?
Yes: The assembly shows a more credible drying trend.
No: Check for trapped layers, an ongoing source or method inconsistency.
Observed answer and evidence
Does the reading rebound after a specific weather or use event?
Yes: Treat the source as active or intermittent.
No: Continue controlled trend logging and compare environmental conditions.
Observed answer and evidence
Safety boundary
Stop rather than create a better clue.
- Do not declare an assembly dry from one surface reading.
- Stop invasive measurement where electrical, structural or hazardous-material risks are unknown.
