Monitoring Wood Moisture Content

Wood is a hygroscopic material that expands and contracts based on the ambient humidity.

Tracking Wood Moisture Content

• Install a data logger in your shop to record hourly temperature and relative humidity changes.
• Check the moisture content of incoming lumber using a pin-type moisture meter before processing.
• Allow kiln-dried lumber to acclimate to the shop environment for at least two weeks.

Seasonal Adjustment Strategies

• Leave expansion gaps between boards to prevent cupping and warping during humid months.
• Apply a sealant to end grain to slow down moisture absorption from the atmosphere.
• Use a crosscut sled to ensure cuts are perfectly square, which prevents the board from twisting as it dries.

Consistent monitoring prevents catastrophic failures in large panel constructions.
