Anyone done any exterior RH testing on structural concrete being renovated for application of coating systems? Just finished placing Wagner Sensors on 40 year old, 5" slab and got readings from the mid 70s to mid 80s. It was 86 degrees and 68% relative humidity at 9 am (sweat my a#! off). I got a hunch they're going to climb. Previous coating had no problems, this work is just part of a complete renovation.
