Step 2: Open All Boxes and Measure the Moisture Content
Bring in all flooring into the job site where it will be installed. Open all boxes along the length and ends. Cut open the inner plastic wrapping and fold back the plastic and cardboard to expose the flooring. Flooring will not acclimate properly if left in the plastic wrapping. Cross-stack the flooring, leaving room between each box for good airflow.
Using a moisture meter, get an initial baseline by measuring the moisture content (MC) of 20 boards per 1,000′ of flooring. Make sure to take random samples across the full lot of flooring. Take the average of all MC% measurements. Also, measure the MC% of the subfloor by taking the average of 20 readings per 1,000′ of subfloor.
In most cases, the MC of the subfloor and flooring must be within 2% of each other to begin the installation. The MC% of the flooring and subfloor should also match the average temperature and RH% of the house.
