You’ve been there. It is day two of a drying project and the numbers on your moisture meter are the same on as they were on day one. Your wet materials don’t seem to be making drying progress. At this point, the most common response is to grab the demolition tools and start removing the wet materials… which may be the completely wrong course of action.
These wet materials might be making perfectly acceptable drying progress, but your meter is not able to show it. This can happen for a number of reasons, including false positives, surface moisture and meter scale limitations.
