Acclimation and In-service Conditions
Note: Wood moisture content measuring devices will not give an accurate reading of bamboo moisture content. Contact the meter
manufacturer on how to convert the reading from wood moisture content to bamboo moisture content.
Acclimation is the process of adjusting (conditioning) the moisture content of bamboo flooring to the environment in which it is expected to
perform. The bamboo flooring is fully acclimated when its moisture content and dimensions (width and length) are stable. For example,
the averaged dimensions and moisture content remain constant for 3 consecutive days. Bamboo flooring must acclimate for as long as
necessary to reach fully acclimated stage. Acclimation time varies depending on geographical area, interior climate control and time of the
year. Minimum acclimation time is 72 hours. In open box, open wrap.
Elevate planks from the floor by placing them on 2”X 2” lumber or equivalence. Place spacers (3/4” to 1” sticks) between each layer or cross
stack the layers for maximum exposure to ambient conditions. Acclimation temperature range is 60°F-80°F and relative humidity (RH) of
35%-55%. Conditions in which the floor was acclimated should be maintained continuously thereafter. Document as much acclimation
information as possible below.

Job Site Condition
Prior to installation, the installer must ensure that at the time of installation, the job site conditions including subfloor/substrate, ambient
temperature and relative humidity, and all impacting variables will not negatively affect floor. Home Legend will decline responsibility for
damages associated with improper installation or poor site conditions.
Storage and Conditions
Do not store flooring in uncontrolled environmental conditions. For example, garages and exterior patios are not acceptable areas to store
flooring. Handle and unload bamboo flooring with care and store within the environmentally controlled site in which it is expected to
perform. Flooring stored on concrete slab should be elevated at least four inches to allow air circulation under cartons.
Existing Home
Existing home should have a consistent room temperature of 60°F-80°F and humidity of 35%-55%. Continual deviation from these conditions
will affect the dimensions of flooring, especially bamboo. During heating season, humidity may be much lower than the acceptable range.
During the heating season, a humidifier is recommended to prevent excess shrinkage in bamboo flooring to low humidity levels. During the
non-heating season, humidity levels can be maintained by using an air conditioner, dehumidifier, or by turning on your heating system
periodically.
New Construction or Remodel
All work involving water, such as pouring basement concrete floors, drywall and plasterwork, plumbing, etc. must be completed well in
advance of the floor delivery. Ensure that the building is enclosed. Where building codes allow, permanent heating and/or air conditioning
systems should be operating at least five days preceding installation to promote proper acclimation and should be maintained during and
after installation. If it is not possible for the permanent heating and/or air conditioning system to be operating before, during and after
installation, a temporary heating and/or dehumidification system that simulate normal living (occupied) conditions can enable the installation
to proceed until the permanent heating and/or air conditioning system is fully operational.
Your job site should have a consistent temperature of 60°F-80°F and relative humidity (RH) of 35%-55% which should be maintained
continuously thereafter.
Basements and Crawl Spaces
Concrete slab or ground must be dry. The ground in the crawl spaces must be completely covered using 6 mil black polyethylene. Crawl
space clearance between the earth and underside of joists should be no less than 18 inches and the perimeter vent area should be equal to
1.5% of the total square footage of the crawl space or as mandated by code.
Concrete Subfloor Requirements
It must have minimum rated strength of 3000 psi.
It must be level to within 1/8” in a 6 foot span or 3/16 inch in a 10 foot span; no bumps or low spots. High spots can be removed by grinding;
depressions can be filled with patching compound formulated for use in floor installation.
It must be clean; no construction debris, soil, mud and any other objects on or adhering to the floor; if necessary, scrape and sweep away
before the installation; no protrusions of nails, debris, metals should remain.
New concrete slab must cure for at least 60 days. It must have a minimum 10 mil polyethylene sheet between the ground and the concrete.
It must meet concrete moisture requirement below.
It must be free from moisture related conditions which can damage the installed flooring.
