This video shows why a weather app on your phone, a touch of the hand, and a "eyeball" assessment are inappropriate for reliably diagnosing a wet wall, floor, or building. Instead of guesswork, you get a practical guide: what to measure, how to interpret the results, and when a simple comparative reading isn't enough. This discussion is particularly important for owners of flooded apartments, houses, and commercial premises, but also for anyone who wants to know what to expect from a drying company. The key takeaway is simple: don't look for "dryness" in a vacuum. First, you need to establish a dry standard—a reference point in a similar, unflooded area—and only then compare the result to a wet area. This approach allows you to meaningfully answer the question of how you know a wall or floor has returned to its pre-damage condition, and why visual appearance alone isn't conclusive. The episode also provides important documentation: insurers often ask for this justification. 🧐 What you'll learn in this episode: ☑️ You'll understand why your phone and weather app don't tell you if a wall is dry ☑️ You'll discover 4 parameters that really matter after a flood ☑️ You'll discover the difference between relative humidity and specific humidity ☑️ You'll see how dew point relates to condensation, mold, and mildew ☑️ You'll learn how to determine a dry standard for comparative measurement ☑️ You'll learn how to read a non-destructive reading to avoid false conclusions ☑️ You'll understand when a MEX5 is sufficient and when a CMEX5 is needed ☑️ You'll learn how to detect moisture under tiles and in the leak zone ☑️ You'll discover why it's important to measure floor moisture before installing the floor ☑️ You'll see how to archive measurements with a photo and geotag and report Frequently Asked Questions: How to check if a wall is dry after flooding? Touch and appearance alone aren't enough. You need to measure the room air parameters, surface temperature, and material moisture, preferably relative to a dry reference point. Why aren't a phone or weather app enough to assess moisture? Because they show general or external data, while after flooding, what matters is the microclimate of a specific room and the reading from the material itself. What is a comparative moisture measurement? This is a non-destructive reading that only makes sense after determining a dry standard in a similar, non-flooded location. It shows the difference between a dry and wet area, instead of pretending to be a single universal number for every material. What is dew point and why does it matter after flooding? It's the temperature at which water vapor begins to condense. If a wall is lower than the dew point, the risk of condensation increases, and with it, mold and mildew problems. Can moisture be detected under tiles without chiseling? Yes. A non-destructive meter can quickly map moisture differences under the floor covering, and measuring the surface temperature helps narrow down the problem. How to check floor moisture before installing the floor? Concrete and screed require a measurement specifically designed for cementitious materials. This episode features the CMEX5, which allows you to assess mass moisture and CM equivalent without drilling the entire surface. 00:00 Phone vs. Real Moisture Measurement 01:03 Why Measure Moisture After Flooding? 02:41 How to Diagnose Water Damage from the First Minute 03:39 Why a Weather App Won't Replace a Meter 04:53 4 Air Parameters That Really Matter 05:18 Dew Point and Water Condensation on a Cold Wall 07:37 MEX5: What Does It Measure and What Materials Does It Measure? 09:04 Wood, Scales, and First Interpretation Pitfalls 11:33 Dry Standard: How Do You Really Know It's Dry? 14:37 Moisture Under Tiles and Locating Leaks Without Chiseling 15:36 Photos, Geotags, and Measurement Archives in the App 17:42 CMEX5: Meter for Concrete, Screed, and Anhydrite 19:05 Why Measure Floor Moisture Before the Floor? 20:52 Mass Moisture and CM Equivalent in Practice 23:34 External probes and even more extensive diagnostics 25:18 What the meter says about a drying company #DeepDry #humiditymeasurement #flooddehumidification #wallhumidity #floorhumidity #humiditymeter #dewpoint #Tramex #Corroventa #MEX5 #CMEX5 #floodedapartment #floodedhouse #drywall #moisturediagnostics #buildingdehumidification #screed #waterleak #floodinsurance #damageadjustment
