The rich color of old heart pine is one of the main benefits of an antique wood floor. A discussion of heart pine may help you to get the look you want. Several species of wood change color significantly as they age. Lumber from freshly sawn antique heart pine logs change from light yellows to deep orange-red browns as time passes. The color change is especially noticeable in longleaf heart pine of high resin content. Other species such as American black cherry, Jatoba (sold as Brazilian cherry) and purple heart also show a significant color transformation. Oxidation of components of the wood drives the change in color and it is accelerated by ultraviolet light. Covering part of a board with aluminum foil and leaving it in strong sun light for a day or two can cause enough darkening to be seen. For a new wood floor much of the change in color takes place in the first few weeks. However the richer tones continue to emerge for several months. Area rugs placed on the floor before this time will keep the areas under the rugs from darkening. Heart wood typically changes color significantly more than sap wood. The color of freshly sawn longleaf pine River recovered® logs is lighter while heart pine reclaimed from buildings is usually darker. Reclaimed heart pine can also contain some yellow portions that are associated with high resin concentrations. The color deepens to the same range in wood from either source. The degree of color change in a new floor is strongly affected by finish that is applied. The type of finish should be considered as a part of the decision to determine the final color of the floor.
