1. Home climate must be kept consistent at least two weeks before bringing the flooring in the home.
2. During Acclimation and after installation the home climate must be kept consistent. For example if home climate is 70F and humidity is 31% maintain these conditions during and after installation. Wood is hydroscopic and it can change dimensions when humidity levels change inside the home. A digital hygrometer can be purchased for $10 dollars to monitor these conditions.
3. Bring wood flooring inside the home, in the middle of the room to begin acclimation to home climate (all painting, or wet work should be done well in advance before acclimation of wood)
4. It is best to place sticks between each row of boxes to allow good air flow around each box.
5. Open up the last box stacked pull out the boards and test the Moisture Content of boards in the box. Also check to finish and milling for any issues. An initial moisture test the first day of acclimation can help give you an idea of how long it may take the floor to acclimate.
6. If the flooring is already at a Equilibrium moisture content to the conditions of the home the installation can begin in a few days as long as the humidity inside the home is kept consistent.
7. If the flooring is not within 2 percent of the moisture content of the subfloor acclimation time is extended until the wood flooring reaches proper balance with the subflooring.
8. If you receive the flooring and the moisture is high over 12% moisture on average then the flooring should not be installed. Return the flooring for new material.
9. Moisture testing should only be done with a species specific moisture meter. That can be set to calculate the species of wood being tested. Do not use a meter that cannot accomplish this task. I suggest talking to Lignomat for a good meter. One example is the Ligno DXC meter. Also be sure the read the meters instructions and know there limitations. Moisture testing should be documented with name of meter, model, and pictures that show date and time.
10. Again do not install flooring until a moisture balance is created between the wood flooring and subfloor. Extended acclimation time may be needed for exotic wood flooring.
11. NWFA states (acclimation can be facilitated by breaking the floor into small lots/ or opening the packaging and to cross stack the material with spacers (3/4” to 1” sticks) between each layer of flooring to allow air circulation around all sides.) Following this NWFA suggestion by opening up all the boxes and removing any plastic in the boxes can quicken the acclimation time, but if this method is done be sure to check for milling or finish issues prior to opening up all the boxes.
12. Once a moisture balance between the flooring and subfloor is achieved the wood flooring can be installed.
