How do you keep timber from yellowing?
The trick to using stain to reduce or eliminate yellowing is to use a pigmented stain, not clear. The pigment should be the same color as the natural wood color. For instance, birch would be stained with a “birch” stain. This puts a pigment layer on top of the wood to block out UV light and inhibit yellowing.
Why did my clear polyurethane turn yellow?
The 2nd major cause is the polyurethane used. Oil based polyurethanes turn the floors yellow…and over time, they become more yellow…and sometimes even a bit orangish. It’s the UV rays from the sun that turn them a darker yellow or amber and the more they are exposed over time, the yellower they get.

Light, and lack of light, can affect how well paint color is preserved and how quickly it yellows. In the case of yellowing due to lack of light, chromophores are to blame.
