Never checked with Jason, but I can tell you it dries pretty fast and hard. I don't think it has an effect on final readings because I have seen readings go up, down and remain the same as my initial readings, depending on the slab conditions. Besides, it stands to reason (to me anyway) that like MVE, any moisture given off is going up into the air more than down into the sensor. I started doing this after my first few tests when I started when I experienced a lot of contamination getting into my sensors. Even had a bunch destroyed on a job when the GC scheduled wet saw cutting in slabs during the test cycle (grrrrr).
