Lumber Liquidators - Climatizing Hardwood Flooring
"A Pro-Active Approach to Limit Cupping, Cracks, Warping
The highest number of complaints encountered with hardwood flooring is
that it cracks, has gaps between the planks, and cups. These results
can be caused by the flooring not being allowed enough time to
climatize to its environment or floor owners not understanding the
characteristics of hardwood floors. (They can also be caused by other
factors, but that's a whole other article!)
Hardwood flooring expands and contracts as the moisture in the air
around it changes. If you've ever watched a mud puddle dry in the
sun, you've seen the cracks and cupping that happen to the soil as the
water evaporates. The same thing happens to wood.
When picking your flooring, choose the one that is right for your
environment and for the subfloor over which it will be installed.
Even the most expensive wood will suffer if installed in the wrong
When you get your hardwood home, open the boxes and spread out the
planks so air can get to all areas. The amount of time to "air" your
flooring depends on the wood. Your flooring provider will give you
Expert installers take moisture readings of the hardwood planks and
check the humidity of the subfloor to ensure they are within the
correct range before installing the flooring. If you're a
do-it-yourselfer, ask you flooring provider for specifics.
After installation, your flooring will still be affected by humidity.
Unless you keep your environment at the same temperature and humidity
365 a year, your floor will have some warping, cupping, gaps, and
cracks. You will see them grow and recede throughout the year. These
are the characteristics and beauty of natural wood flooring."

"Before installation, the planks should be unpacked and given a couple
days to properly climatize to their new environment. The sub-floor
should be covered with a vapor barrier in order to prevent moisture
from seeping into the planks. The sub-floor should also be insulated
to reduce temperature extremes."

"Subfloors must be dry - Hardwood tolerance of moisture content can
only vary within 6%.
Make sure all work involving water or moisture (plumbing, drywall,
taping) is complete before delivery.
Install as close to the end of the project as possible.
Hardwood flooring requires 72 hours to climatize prior to installation."
