readings are attempted, otherwise results may
not accurately reflect the amount of moisture
present or moisture movement in the concrete
during normal operating conditions.
Removal of covering materials
All covering materials, adhesive residue, curing
compound, sealers, paints etc., shall be removed
from the test surface prior to testing. The test
surface must be clean, bare concrete.
Observe all health and safety practices relevant
to cleaning and removal of these types of
materials. Removal of covering materials and
cleaning, if required, shall take place a minimum
of 48 hours prior to testing.
Use of water based cleaning methods that could
lead to elevated surface and/or sub-surface
moisture levels in the concrete are not
recommended, and testing after such treatment
could result in elevated readings.
No visible water in liquid form should be present
on the concrete at the time of testing.
Avoid testing in locations subject to direct
sunlight or sources of heat. Use of artificial aids
for accelerated drying of concrete is not
recommended. If they are being used it is
recommended they should be turned off at least
four days before taking final readings.
