“There are many reasons why calcium chloride moisture emission testing cannot do what a relative humidity test can accomplish. The bottom line is that RH testing is a far better predictor of whether or not a floor covering or coating on a concrete slab will succeed or fail. It is unnecessary to perform moisture emission tests in addition to relative humidity.”
