Moisture and Moisture-related Conditions
With all that said, what issue results in the greatest number of call backs?
Unusual moisture conditions
Unusual moisture conditions are those that are different from the conditions expected when the space is occupied. This is why NOFMA installation instructions say a "near- occupied" environment must be established before the flooring is delivered to the site. What constitutes "near occupied" conditions? Near occupied means the structure is near enough to completion for construction-introduced extra moisture to have dried to normal conditions and that these conditions will remain through completion of the project. Sometimes running the HVAC equipment is necessary to reach these conditions, sometimes not. That means the structure is dried in, the windows and doors are installed and the dry wall has been mudded, taped and primed.
• Be the professional; know your product and the average moisture conditions required of the product and the jobsite.
• Require near occupied environmental conditions before delivery.
• Make common sense observations
• Check jobsite conditions with a moisture meter.
• Educate your workers and builders.
• Do not even deliver product to sites with excessive moisture.
• Assess marginal conditions for change in the right direction.
