Moisture mitigation is the use of a coating or membrane system to block excess moisture vapor from a concrete slab before flooring is installed.

Relative humidity (RH) testing measures the internal moisture condition of a concrete slab using in-situ probes, following the ASTM F2170 standard.

The calcium chloride test measures moisture vapor coming through a concrete slab, reported in pounds per 1,000 square feet per 24 hours.

Dew point is the temperature at which airborne moisture condenses onto a surface, and it’s one of the most important numbers to check before coating a floor.

Moisture vapor emission rate (MVER) measures how much water vapor passes through a concrete slab, a key test before coating.
