When Moisture Testing Is Not Required
A moisture test is not required when all specified conditions are met: the
concrete is surface dry, at least 28 days old, has a surface temperature of
60°F or higher, and has an intact structural waterproofing membrane beneath
the slab.
Confirm subfloor preparation, application rate, required number of coats,
drying times, flooring compatibility, and current manufacturer installation
instructions before use. All no-test conditions must be satisfied.
