Why does wood change colour over time? Wood is a natural product, and as such is sensitive to environmental changes. Direct sunlight will cause the floor’s colour to fade over time. The extent to which a floor changes colour depends on the species, the type of finish, and the amount of contact with direct sunlight. Most floors will fade in colour, so obvious differences in colour at an early stage of the floor’s life become less obvious as the colour becomes more uniform. Also you should consider that flooring will not look the same as when you buy it forever! How to prevent your floor fading in colour The most important thing to do to protect your investment is to regularly maintain your floor, as this is the best way of keeping your floor looking its best.
