Table V Dew Point
Table V Dew Point
HOW TO USE THIS CHART: If the air temperature is 80°F and the RH is 65%, the dew point
is 66°F. No coating should be applied unless the surface temperature of the slab is 71°F or
higher.
DEW POINT: Temperature at which moisture will condense on the surface of an object.
No coatings should be applied unless surface of the concrete slab is a minimum of 5
degrees above this point. Ambient temperature must be maintained during curing, or can
be falling, but never rising.
RELATIVE HUMIDITY (RH): The amount of water vapor in a mixture of air and water
vapor. It is defined as the ratio of the partial pressure of water vapor in an air-water
mixture to the saturated vapor pressure of water at a prescribed temperature.
AMBIENT AIR TEMPERATURE: The ambient temperature is a non-specific phrase used to
describe the outside temperature. When taking the temperature with a thermometer, you
are getting a general idea of the temperature of the surrounding air without taking into
account the humidity or wind in the air.
