What causes hardwood floors and polyurethane to yellow?
1
The first is that some species are just naturally yellow (especially pines) and they become more yellow over time due to the UV rays from the sun (especially pines, bamboos and maples).
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.
