Wasted a full day and $300 on a 'moisture meter' that was basically a toy
Got a job last month for a glue-down LVT install in a basement. The concrete felt a bit cool, but the homeowner swore it was dry. I was in a hurry and grabbed this digital moisture meter I saw online for about $300, thinking it was a pro tool. Thing gave me a perfect reading, so I went ahead and glued it all down. Fast forward three weeks, the client calls me back because the planks are bubbling and the glue is failing. Had to rip it all up, and the real pro meter I borrowed from a friend showed the slab was way too damp. That cheap meter just read surface temp or something, not actual moisture. Lost a day of labor and ate the cost of the new material. Anyone know a truly reliable brand for concrete moisture checks that won't lie to you?
