ᐅ Why is the finish on the edges of my Billy shelf fading?

Hello everyone,

I have a Billy bookcase from IKEA that I bought about 2 years ago. Unfortunately, I have noticed that the finish on the edges of the bookcase is gradually peeling or changing. It seems like the surface is particularly vulnerable, even though I am quite careful and don’t use the bookcase excessively.

I’m interested in what usually causes the color fading or peeling on the edges of Billy bookcases. Is it material fatigue, poor coating, or perhaps low-quality veneer?

I have also wondered whether factors like moisture, cleaning with strong agents, or simple mechanical wear could be the main reason, but I’m not sure. Are there any known tips for protecting or restoring the surface?

Thanks for your expertise!

It’s great that you described this so precisely! 🙂 I had exactly the same issue – and for me, it was definitely because the edge banding, meaning the veneer or paint layer, was simply thin and less durable. Especially with frequent bumps or if something wasn’t handled gently during assembly, the color tends to chip off.

I carefully touched up my edges with acrylic paint back then. That helped because it provides better scratch resistance and preserves the color. But be careful: don’t apply too thickly, or it will look unnatural quickly! Keep it up, you’ll manage! 🙂

What is typically the cause of discoloration or color loss on the edges of Billy bookcases

The observed issue can be explained from a technical perspective: Billy bookcases are mainly made of particleboard covered with a melamine resin coating or laminate. The edges are usually protected with a thin trim or edge banding to safeguard the panels.

The edge banding is less durable than the larger surface area because it is thinner and exposed to mechanical stress, impact, and friction forces.

Another factor can be the influence of atmospheric humidity. Fluctuations in moisture levels cause slight swelling and shrinking, which can lead to visible damage or color changes along the edges. Additionally, cleaning agents containing solvents or harsh chemicals can dissolve or damage the coating.

In conclusion, color loss at the edges is usually due to normal wear and tear related to the material properties. To prevent this, gentle cleaning is recommended, and if needed, sealing the edges with a clear lacquer.

This is an important point I would like to add: The edges of Billy shelves are not made of solid particleboard but are usually covered with ABS edging or thin edge banding that is mechanically applied over the particleboard edges.

Due to strong pressure, impacts, or constant rubbing, the edge banding wears out quickly, especially if there are small irregularities at the cut edges where the banding does not fully adhere. These minor defects can occur when moving or transporting the shelf.

The color change happens because the white decorative laminate on the edge strips wears off or even peels, revealing the underlying wood material, which is darker.

Additionally, the UV resistance of the laminates may be limited, so over time and with exposure to light, discoloration can occur.

Is the discoloration on your shelf mainly along longer edges or especially at joints and corners? Are these areas frequently touched or stressed?

My advice: If you plan to do repairs, definitely use fine-grain edging or edge strips, and seal the surface multiple times with special edge lacquer.

Thanks for asking! For me, the paint wear mainly occurs on the outer edges of the side panels, so along the long edges of the shelves. Exactly where you’d hold the shelf when, for example, taking a box out or moving it. The corners aren’t as badly affected because I’m usually more careful with those.

That sounds like a good solution. I’ve never used acrylic lacquer for this before, so it would be great if someone could recommend which products are suitable to ensure the treatment really helps and the paint doesn’t peel further. After applying the finish, the surface shouldn’t appear noticeably glossy or opaque either, as I want to maintain the original Billy look.

I would like to provide a structured suggestion for repairing the peeled edges:

1. Preparation: Lightly sand the affected edges first with very fine sandpaper (grit 400–600) to remove loose paint residues and uneven spots.

2. Cleaning: Then, wipe off the sanding dust with a damp cloth.

3. Paint selection: Water-based acrylic paints with a matte to satin finish are suitable for the touch-up. These can be applied well with a fine brush or a small sponge applicator.

4. Application: Apply several thin layers, allowing each to dry thoroughly. This makes the surface durable without noticeable changes in gloss.

5. Drying time: Allow at least 12 hours between coats.

Additionally, I recommend using only mild, pH-neutral cleaning agents in the future, as harsh cleaners can damage the coating.

Die Oberfläche sollte nach dem Lackieren auch nicht sichtbar glänzend oder opak wirken

That is exactly why matte acrylic paints are a good choice.

I hope this guide helps you. If you like, I can also provide some product recommendations.
