How Long Does Bamboo Flooring Need to Acclimate?

Acclimation is the first and most important step to ensuring that your bamboo or hardwood floors provide a lifetime of quality use.

Does Bamboo Flooring Need to Acclimate

What is Acclimation?

Acclimation is, in the simplest sense, where the structures of a material adjust to their surrounding environment – with the material undergoing changes in temperature and humidity. As pertaining to flooring, acclimation means getting the wood accustomed to the environment in which it’s going to be installed. This is done by turning on the climate control and placing and opening the boxes in the rooms in which they’re going to be installed. There is a certain amount of time the flooring must stay like this before installation in order to allow the wood to balance itself out (acclimate) with the environment (read our guide on bamboo flooring installation).

Why Would Flooring Need to Acclimate?

Acclimation is important for flooring as bamboo and wood are porous, with microscopic holes that allow for air circulation. Along with this air comes the carrying of water molecules i.e. humidity.

All wood and bamboo flooring is hygroscopic, meaning it takes in and releases moisture in order to balance itself out with the environment. Should the air in a room be more humid than the bamboo or wood, the planks will take on humidity, and if it’s too humid they will swell slightly.

If the air in a room is less humid than the bamboo or wood, the planks will release humidity. If it’s too dry, they may shrink slightly, and if excessive, they may cup. When the atmosphere is less humid and the planks dry out, small gaps can develop between the flooring planks in winter and typically close back up in summer when the humidity increases.

Does Bamboo Flooring Need to Acclimate?

High-quality bamboo flooring requires at least 72 hours to acclimate, while lower quality brands require 1-2 weeks. All wood floors require some acclimation, and we recommend that you always follow the manufacturer’s installation instructions for detailed acclimation periods.

The differences between brands lie in the moisture content of the flooring – the higher the moisture content, the longer it will take to acclimate.

Testing the Moisture Content of Bamboo Flooring

Due to the sheer density of the planks and some binding resins, bamboo flooring can’t typically be tested for moisture in the same way hardwood flooring can. For classic bamboo floors, pin meters are recommended so you can insert the pins parallel to the grain to the same depth. For strand-woven bamboo, pinless (surface/face) meters are recommended.

Is Bamboo Flooring Sensitive to Moisture?

Excessive moisture and humidity can damage all wood flooring; however, bamboo is slightly more water-resistant than wood flooring (you can read more about this in our blog, Is Bamboo Flooring Waterproof?).

Specifically, the optimal environment for bamboo flooring is 40% to 60% humidity with a temperature range between 60 and 80 degrees Fahrenheit.

What Steps Can be Taken to Ensure Bamboo Flooring Acclimates Properly?

  • Step 1: First, ensure the room’s humidity and temperature are at the right levels and won’t fluctuate too excessively. 40%-60% humidity is required for healthy wood and bamboo floors.
  • Step 2: Cross stack the boxes for better airflow.
  • Step 3: Cut open the long sides and end flaps of the flooring boxes including the interior plastic to ensure air can circulate through them.
  • Step 4: Allow at least 72 hours for the bamboo flooring to acclimate to the temperature and humidity of the room. If you are in an excessively dry or humid climate, allow 10 days of acclimation instead of 3 days.
  • Step 5: The bamboo flooring will be ready for installation as soon as the difference in moisture content between the flooring and subfloor is within 3%.



How to acclimate hardwood and bamboo flooring

There we have it, a quick guide to hopefully answer the question of whether your bamboo flooring needs to acclimate. At least now you know how humidity affects wood flooring and in particular, bamboo flooring.

  1. Can you recommend a flooring company to look at my stranded bamboo floor and tell us why we are getting dark patches that are rough to the touch. We are in Bradenton, Florida

    • Hi Lawrence, have you reached out to your bamboo flooring manufacturer to see what they recommend? Dark spots in hardwood floors sometimes point to moisture issues in the sub-floor. One way to get to the root of the cause is to hire an NWFA certified inspector to come out and look at it as well. Best of luck!
