"Looking for a solution, we requested MV be applied with D.R. Horton on a test slab with a reading of 99% relative humidity using Wagnor's Probe & Meter for ASTM F2170 testing. The slab was 45 days old, MV was applied and 48 hours later we performed an ASTM 21 bag test which remained on the slab beyond the expected test time (18 to 24 hours), I left it on for 10 days.
10 days later I could barely get the duct tape and the slab was bone dry under the plastic.
Absolutely incredible results."
