Some wood species are light sensitive.  Hardwood Floors made from UV light sensitive wood will darken over time.  It is important to move furniture and rugs regularly for the first year to allow an equal light pattern reach the floor.  If a portion of the floor is covered and the areas under the covering appears lighter remove the covering to allow the floor to equalize.  It may take a few months for the covered area to darken to an equal color as rest of the flooring.

Light Sensitive Species are listed below:

• American Cherry
• Andiroba
• Australian Cypress
• Bloodwood
• Brazilian Cherry
• Cumaru
• Dark Sucupira
• IPE
• Kempus
• Massaranduba
• Santos Mahogany
• Sumatra Mahogany
• Sumatra Rosewood
• Teak
• Tiete Rosewood
• Tigerwood
• Walnut

A small amount of change can occur in Hickory and Maple.
