ᐅ Kallax discolored after sun exposure – how to restore the surface?

Hello everyone,

I left my Kallax shelf in the sun for several weeks to place some plants on it. Unfortunately, the surface of the shelf has faded significantly—almost white in some sun-exposed areas. My question is: How can I restore or at least visually improve this faded surface without repainting the entire shelf? Are there methods to balance or mask the fading without changing the original look too much?

Thanks for your tips and experiences!

Hey, I know that all too well! It’s really frustrating when the Kallax fades like that. 😞

You can try gently sanding the surfaces with fine sandpaper and then re-treating them with stain or a wood oil. This often restores a nice color and also helps protect against further fading. Good luck, you’ll manage it! 🙂

Apply wood stain or furniture oil, allow it to absorb well, then wipe off any excess. This often helps.

That sounds good at first, thanks! Do you really mean sandpaper? Is there a grit you would recommend to avoid removing too much of the surface?

And what about the color – should the stain be light or dark? I want to keep the contrast with the non-faded areas as low as possible.

It is important to know the exact material structure: Kallax shelves are usually made of melamine-coated chipboard, not solid wood construction.

Therefore, light sanding can easily damage the surface rather than improve it. Stain does not penetrate melamine but acts more superficially—usually with little effect or resulting in an unattractive finish.

It is better to check whether a specially suitable surface for recoloring is available or if a replacement panel is more cost-effective.

I can only agree with BAUEVA: Kallax is melamine-coated, which means you can’t simply sand the surface without damaging the protective layer.

My tip:
1. Clean the surface thoroughly with isopropanol to remove any dirt.
2. Use a special furniture pen or marker that matches the color of your Kallax.
3. Then carefully seal it with a clear matte varnish to protect the color and slow down fading.

It takes a bit of effort, but it’s often the best solution without having to work on the entire frame.
