Acclimation is not all about time
When floors are not properly acclimated, they may expand or shrink after installation, resulting in cupping, crowning or squeaking. There are no hard estimates for how long it will take wood to acclimate, but allow for anywhere between 5 and 14 days.
Our pallet should broken up and taken into HVAC area where they can be separated as much as possible. The middle boards should be close to original Kiln dried content. The outer boards are likely to reflect current conditions such as higher moisture content if humid or raining.
The goal of acclimation is to reach equilibrium moisture content (EMC) in the flooring, a point at which the wood will neither lose nor gain moisture. As a rule of thumb, try to avoid installing new floors during bouts of extreme weather such as a snowy winter, when humidity is too high, or a dry summer, when the humidity is too low. Spring and fall have less fluctuations in humidity levels and are more ideal.
Acclimating wood floors
All wood is extremely sensitive to climate and moisture, and should always be stored so that conditions between 60 and 80 degrees Fahrenheit and 30 to 50 percent relative humidity can be maintained – in other words, normal living conditions in most homes. Extreme temperature and moisture levels can destroy your flooring before it’s even installed, so climate control during storage, transportation, and installation is vitally important.
Remember that hardwood loses moisture and shrinks in dry climates, and expands in humid climates. Ensure that you allow your hardwood to acclimatize to the moisture content and temperature of its new home before installing it. This process takes at least two weeks, sometimes longer, so do not rush into installing a wood floor. The last thing you want is to install a new hardwood floor and have the wood shrink or expand after installation.
The acclimation process is more a matter of waiting to achieve results, rather than waiting until a certain number of days or weeks has passed. Factor the species of wood, the room temperature, relative humidity, and moisture content of both the flooring and the environment.
Two tools to help measure this process are a wood moisture meter, which can check the water content of the wood, and a hygrometer, to check the relative humidity of the environment in which it will be installed. You should allow hardwood to acclimate in an environment with the same living conditions as its final destination.
Wood flooring is a hygro-scopic material subject that expands or contracts with the amount of moisture, temperature, and humidity within the surrounding environment. Wood flooring simply needs to reach moisture content level in equilibrium with the surrounding environment (EMC) where it will be installed. The process of reaching this equilibrium is defined as acclimation.
According to the National Wood Flooring Association, the process of acclimation is as follows:
Acclimation by steps
Finally, if the installation site is in a location with very wet winters or very dry summers, for example, you may consider completing the installation during the fall or spring; aim for a time when the humidity is not too high or too low.The most important thing you can do to prepare hardwood for installation is to acclimate it properly to the normal living conditions of its new home. Even in very wet or dry climates, proper acclimation is the key to successful hardwood flooring installation.
