Pre-test conditioning and preparation
For best and most accurate results, to allow for an
accurate reflection of the amount of moisture present
and moisture movement in the slab during normal
operating conditions:
• Artificial heating or drying equipment should be
turned off at least 96 hours before final readings
are taken.
• Internal conditions of the building should have been
at normal service temperature and humidity for at
least 48 hours.
Prior to testing, the surface should be prepared:
• The test area should be clean and free of any foreign
substances.
• All covering materials, adhesive residue, curing
compound, sealers, paints, etc., should be removed
to expose a test area of clean bare concrete, strictly
observing all the appropriate safety and health
practices.
• Removal of covering materials and cleaning if
required should 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 floor slab are not
recommended.
