Can water be sprayed onto an IOZ coated surface, which has not fully cured due to low humid conditions, to accelerate the cure?

From Eugen Oranici of P&CES on March 28, 2019:
Yes, it can be when humidity it is too low.

From Larry Muzia of Exceletech Coating & Applications, LLC on March 27, 2019:
Iozinc will have curing issues whenever the humidity is below 50%. In areas of low humidity, it is practical to raise the humidity by either wetting the floor constantly or allowing the zinc to sit for a brief period, during which you may directly water mist the applied iozinc. It is very important to insure you have sufficient humidity after application and during the curing stage to insure the iozinc properly cures to achieve the physical properties which will allow it to perform. It is known that it may appear to be nice and cured; however, appearance is not sufficient criteria. Although the MEK rub test is one test to assess cure, I prefer the pencil hardness or nickel rub test, pass/fail.

From Hugh O'Neill of Fastrack Contracting Ltd on March 26, 2019:
Water misting to facilitate full cure can be used in conditions of low humidity.
