Wood is a natural product containing natural characteristics such as variations in colour, tone, and graining. Some variation in colour and small sound knots is to be expected in a natural wood floor. Please note that the display sample may not always be a true representation of the final wood floor product. For this reason, new and/or replacement flooring may not exactly match display samples and/or existing flooring. A natural wood floor is subject to colour changes with the exposure to normal sunlight. These colour changes should be expected and are a desired attribute in the uniqueness of a wood floor. Product image colours may vary due to print processes and monitor display settings.
