Make sure the subfloor is structurally sound, level and is free
of dust and debris. The deflection cannot exceed L/360 of the
span under intended live and dead loads. Check for protruding
nails and/or defects in the subfloor. If installing over concrete,
the concrete must be dry with moisture emission rates that
do not exceed 3lbs. per 1000 square feet per 24 hours as
measured by the Anhydrous Calcium Chloride Test.
