Establishing Concrete Baselines:
Sub-Floor Installation Suitability for Wagner
Concrete Meters
Wagner Concrete Meters detect moisture in concrete
and provide a relative reading, not a percentage of
relative humidity, moisture content or lbs./1000 sq.
ft. (kg. / 304.8 sq.m.)
You can establish your own baseline or comfort range
reading for use with the Wagner C575 meter. Once
established, the baseline will become your "not-to-
exceed" reading, indicating sub-floors that you cannot
safely install your adhesives, paints or floor coverings
over. You can easily establish your own baseline(s) in
the following manner.
To establish baseline date on how the Wagner C575
Meter corrolates a specifi application of concrete
moisture contest by weight.
1. % MC (moisture content) = wet weight minus -
dry weight divided by dry weight mulitplied by
100
wet weight - dry weight
2. First obtain a sample of concrete that is oven
dry weight
x
100 = % MC
