ᐅ KALLAX paint is peeling off after exposure to sunlight – how can this be resolved?

GakarHello everyone,
I have an issue with my IKEA KALLAX shelving unit where the finish on the shelves starts to peel off along the edges after relatively short exposure to direct sunlight. The affected areas feel rough, and the surface flakes off in thin layers. I suspect this is a reaction between UV radiation and the surface, as the shelving unit is placed in a south-facing room where sunlight is strong both in the morning and afternoon.
My question is whether anyone knows of a permanent solution or at least a good repair or protective approach to prevent this peeling? Are there special coatings or sealants that can be applied afterwards without having to sand down or repaint the entire piece? Also, I’m curious if this is a known issue with KALLAX or a unique case due to the specific building conditions.
Thanks for any tips and shared experiences!

Your issue is actually quite common with furniture made from particleboard with a melamine or lacquer coating, especially when exposed to strong UV light. UV radiation can make the top layer brittle, causing it to peel off at the edges.
Here are a few steps that might help you:
1. Carefully remove all peeling lacquer residues using fine-grit sandpaper (e.g., 220).
2. Thoroughly clean the surface to remove dust and grease.
3. Apply a UV-resistant clear coat specifically designed for wood or veneered surfaces. Make sure it is approved for interior use.
4. Additionally, a UV protection film or window foil may help prevent further damage.
Common mistakes include using paints or lacquers that are not UV-resistant or skipping the surface preparation before painting.
In short: proper preparation and an appropriate UV-protection clear coat can usually reduce or completely prevent the problem under normal conditions.

Timmyse3610 Nov 2021 10:19That sounds really frustrating, Gakar! As much as I like Ikea, KALLAX isn’t exactly the most durable furniture, especially when exposed to strong sunlight. I had a similar issue with a desk once, and I was pretty upset at first as well.
I would recommend taking Landontau’s advice seriously, and maybe also consider whether shutters or blinds could be used more frequently in your situation. This way, you can protect the surfaces before significant damage occurs.
A little encouragement: with some patience and the right materials, you’ll be able to fix it up well. 🙂

Additional information:
The peeling of the finish on KALLAX shelves usually results from the use of melamine-coated particle boards, which can fade under UV exposure and cause the binding agents in the finish to break down. This leads to gradual peeling, especially on the edges due to mechanical stress.
Possible solutions:
- Reducing sunlight exposure, for example by using UV protection film on windows or curtains.
- For refinishing, I recommend using an acrylic or PU clear coat with high UV protection, specifically designed for interior furniture surfaces.
- Before applying, it is essential to lightly sand the peeling areas to ensure proper adhesion of the new finish.
A complete surface rebuild requires more effort and is rarely practical for KALLAX particle boards.
Beware of finishes with a high solvent content, as these can damage the material.

Apply a UV-resistant clear coatThank you for the detailed explanation. I underestimated the importance of sanding beforehand; it seems to be crucial for good adhesion.

One more question for everyone: Does anyone know of a specific UV-protective varnish (brand or product type) that has proven effective? Preferably with a matte finish, because I don’t want the shelf to look glossy.
I’d really appreciate any recommendations!
