The core idea
Materials need a documented drying trend or acceptable condition before they are enclosed, coated or rebuilt.
How the mechanism works
Surface dryness can precede deeper drying, and low-permeance finishes can trap remaining moisture.
When it becomes relevant
Typical trigger: After leak control, cleaning or material removal.
Evidence that supports this interpretation
- Repeated readings decline or stabilize at references
- Temperature and humidity context is recorded
- Hidden layers are assessed where necessary
Evidence that weakens it
- Only one reading exists
- The surface was heated immediately before testing
- Reference material differs
What this concept cannot prove alone
A single observation, image or meter reading cannot confirm the complete failure pathway. Use this concept to form better questions, compare alternatives and decide which safe observation would be most informative next.
Safety and professional boundary
Drying targets and salvage decisions for structural or contaminated materials should be set by qualified professionals.
