Sun Darkens Hardwood Floors
Our new home has Brazilian Cherry floors throughout the first floor. When we chose the Brazilian Cherry flooring a friend of ours warned us that cherry flooring will darken from sun light. If you use area rugs then you will notice the flooring under the carpet remains it’s original color while the area of flooring exposed to sun light will darken over time.
As you can see in the photo the Brazilian Cherry flooring under our area rug in the breakfast nook is much lighter than the floor that’s exposed to direct sun light (I’ve pulled back the carpet in the photo so you can see the difference). This significant difference in the flooring color has happened in just under two years time.
Ultraviolet Light Causes Wood Flooring To Darken
Ultraviolet light from the sun causes the tannins in the Brazilian Cherry floors to darken over time. Most Cherry floors, American, Black, and Brazilian will darken when exposed to ultraviolet light. This problem is most often seen when area or throw rugs are put down to cover the flooring for extended periods of time.
I can only think of a couple of solutions to help with this situation. You could install a ultraviolet film to your windows to reduce the amount of UV rays that are exposed to the floor. You could also use curtains and blinds to shield the amount of direct sun light that hits the floor. I suppose if this has already happened then you can pull up the rugs for a few months at a time and try to expose those areas to UV light so they can darken as well.
If you are looking to buy a home with cherry floors then take a look under any area rugs. You may well find this issue and want to consider it before making your purchase decision.
Have you seen this before? Any suggestions on how to prevent it or fix it?
