Equalizing your solid wood flooring
Solid Wood Floors, both unfinished and pre-finished, MUST be equalized properly before installation. Please follow these recommendations for equalizing:
Background to equalizing Solid Wood Flooring
Wood is a natural porous material, which continues to breathe even after installation and finishing. Wood has a cellular structure, and much like a sponge, expands as it picks up moisture and shrinks when it gives moisture off. It is this movement which can cause cracks, separation, cupping, swelling and lifting of your wood floor. All wood will eventually acclimate itself to its surroundings.
This is known as reaching the equilibrium point. The exact equilibrium point to be reached by all wood elements on a job site can be accurately predicted by taking relative humidity and temperature readings at the site and then use the chart below to find the expected equilibrium moisture content. The numbers in the middle of the chart are the equilibrium, moisture content point that all wood elements will reach.
