Let’s talk a little about this word – “acclimating”. Inspectors are hired to come in and look at concerns or issues on flooring. Many times,the first statement the contractor makes in defense is: “We let the product acclimate 3 days prior to installing!”
The next question out of this inspectors mouth is: “Great to hear, was the product acclimated??”
Acclimation is not a period of time. If you are acclimating a product that is hygroscopic, or a product that will release or absorb moisture based on the environment it is exposed to, then we need to make sure that first, the environment is to the manufacturer’s specifications as to relative humidity and temperature and second, that the product has reached its equilibrium moisture content based on those readings. In other words, has the flooring acclimated or does it need more time? Temperature and relative humidity are what the products acclimating to and consequently, will either release moisture if too high or take on moisture if too low. Product can shrink or swell during this acclimation period. Let’s face it, we don’t want it shrinking or swelling AFTER it’s installed. Moisture testing by the installer is needed to make these determinations.
Minimally, if you are not trusting that all these moisture readings are going to be taken, at least expose the product to the environment that it will be “living in” and be sure that “wet work” (painting, drywall work…) is NOT being done during this acclimation period. Also stack the product in such a way that air flow gets to the boxes rather than stacking the boxes tight in a square. Additionally, do not stack the boxes on the bare concrete! Most of all, read and follow the installation instructions the manufacturer supplies.
If you have any doubt whether or not the product has acclimated properly – WAIT!!
