Yellow cast on new linoleum is no cause for alarm Q. I wanted to install Marmoleum Click flooring in my daughter’s room because it is supposed to be very good for healthy indoor air quality, and my daughter has allergies. But when the installer from the flooring company started taking the flooring out of the boxes, the color did not look like what we chose. Instead, it looked like the material had yellowed, like something does when it gets old. The installer said this was normal and that it would go away. But with the price of this product already being higher than many other options, I did not want to take the chance. I sent the flooring back and cancelled the job. I really wanted this floor. Is it possible that I just got a batch that was defective? A. The problem you are describing is not a defect. It is called “ambering,” which is a yellowish cast that appears on Marmoleum – and the competing brands of linoleum. As the installer said, it is normal. It goes away entirely after the flooring comes out of the box and is exposed to light for a few days.
