Why does the color of my Billy bookshelf fade over time? I have a few shelves that have noticeably lost color intensity after about two years of use, especially when exposed to direct sunlight. Are there any material or manufacturing factors that might explain this fading? I’m particularly interested in whether it’s related to the paint, UV exposure, or possibly the particleboard used. Or could it be care instructions that I might have overlooked? I use the shelf in a bright room and wonder how durable the color quality of the BILLY really is.
That is a very good and valid question. Essentially, the BILLY shelf is made of particleboard with a wood veneer or melamine coating, sometimes also lacquered. The fading of the color mainly depends on two factors: first, UV radiation, which can break down the material as well as the pigments in the lacquer or coating, and second, the type of dyes used and their resistance to environmental influences.
Most BILLY shelves have a surface that is not optimally protected against UV light because the focus is more on cost-effective manufacturing. The type of paint can also explain why it fades faster compared to solid wood or high-density MDF panels with special sealing.
It is important to mention that temperature, humidity, and cleaning with unsuitable products can also damage the surface. Apart from the typical UV-related color changes, improper maintenance can significantly reduce color intensity.
What exactly does your room look like in terms of light and climate exposure? Are you using cleaning agents that might have an aggressive effect?

The shelf is located near the south-facing window, so it gets several hours of sunlight daily. At the same time, the room is not air-conditioned, and the humidity fluctuates between 40 and 60 percent. I usually clean with a slightly damp microfiber cloth, without any greasy or abrasive cleaners—so rather mild. Still, the color fading seems quite noticeable even in areas not directly facing the sun.
I’d like to add a few technical details: The typical construction of BILLY consists of particleboard with a laminated melamine foil or a painted surface. The melamine foil itself is so thin that UV rays can easily penetrate it. If the paint is not formulated to be UV-resistant, the color pigments break down over time into smaller molecules that absorb less light – which makes the color appear “faded.”
Furthermore, every paint contains different types of pigments that vary in their UV resistance. IKEA’s formulation isn’t always consistent because it can change between batches to optimize costs. Unfortunately, budget furniture doesn’t always use premium UV protection.
The time factor also plays a role. UV-degraded polymers and paints change their structure, which also leads to a kind of superficial aging mechanically – this results in a duller, less smooth surface, which intensifies the effect. Additionally, slight thermal stress from sunlight exposure can damage the polymer bonds.
The best location would be one that provides enough light but avoids direct sunlight to minimize this problem. And of course, gentle maintenance without aggressive cleaners is recommended.

I’m happy to explain this again for everyone who isn’t familiar with paints and UV radiation.
The color deteriorates because sunlight passes through the window and hits the surface. This causes the slow breakdown of the color pigments and the coating.
BILLY shelves are made from affordable materials that don’t offer the same protection against UV light as more expensive types of wood or specially treated finishes.
Additionally, the melamine coating is heavily stressed—it gradually loses its resistance to light and moisture over time, especially without a special UV filter.
It helps to regularly dust the shelf and avoid direct sunlight. Alternatively, applying UV protection film to the windows can assist.
I hope this clarifies the reasons!
