ᐅ KALLAX Side Panel Cracked – Is It Possible to Glue It or Should It Be Replaced?

Hello everyone,

I just noticed that one of the side panels on my IKEA KALLAX shelf has cracked. It is the narrow side panel attached on the outside, basically the covering panel.

My question is whether anyone has experience with effectively and permanently gluing such a side panel, or if replacing the entire side panel is the only solution?

If gluing is an option: Which adhesives work well for this, and what is the recommended procedure to ensure the panel stays stable and the repair isn’t very noticeable?

The damage is at a corner, a kind of chip with a crack, not a large break. The furniture is a bit older, maybe 3-4 years, but it doesn’t carry much weight on top.

I would appreciate any specific tips or personal experiences, thanks!

Hello Grahame48,

it’s good that you’re asking specifically about this. Basically, the side panels of the KALLAX shelf are made of coated particleboard or MDF, which are not designed to handle significant point loads. If a corner is chipped, you can usually repair it with good wood glue.

I recommend using a PU adhesive (polyurethane glue), as it provides high strength and is somewhat more flexible than regular wood glue. It’s important to clean the surfaces to be glued well and, if possible, lightly sand them to improve adhesion.

After gluing, you should clamp the panel under pressure as long as possible, for example with clamps or at least by weighting it down with something heavy. Allow the glue to cure for at least 24 hours.

If the panel is severely damaged, however, stability cannot be guaranteed. In that case, it may be worth ordering a replacement if that is still possible.

I hope this helps!

Hey Grahame48,

wow, the KALLAX is really great, but one of the side panels cracked? No need to panic 🙂

I can definitely confirm that! And here’s another tip: if you can still get original KALLAX side panels, I’d recommend replacing them – it’s simply cleaner and more sustainable than gluing.

But gluing is a great alternative if you want to fix it quickly and with minimal effort. Just make sure to secure the panel well – and let the adhesive cure fully.

It will surely turn out great again! Good luck, and let us know how it went!

Hello Grahame48,

I’d like to give you a brief guide on how to approach repairing a cracked KALLAX side panel if you want to glue it:

1. Cleaning: Carefully remove dust, old glue residues, or grease from the break area.

2. Preparation: Lightly sand the broken edges with fine sandpaper (around grit 120-150) to slightly roughen the surface.

3. Adhesive selection: A polyurethane (PU) glue (e.g., Titebond Polyurethane) or a strong wood glue suitable for coated MDF or particleboard is ideal.

4. Application: Apply the adhesive generously to both bonding surfaces to fill any gaps.

5. Clamping: Press the broken pieces firmly together using clamps. If you don’t have clamps, securely taping the joint with painter’s tape or applying an appropriate weight can help.

6. Curing time: Allow at least 24 hours to fully cure for maximum stability.

7. Finishing: Carefully sand off any glue residues or smooth the area with fine sandpaper, then visually touch up with paint or a matching marker.

If the panel will be subjected to frequent stress or additional load (e.g., boxes regularly removed from the side), I recommend replacing the panel.

Summary: Gluing is possible and holds well if done cleanly with good adhesive. However, replacement is always the safer option.

Hope this helps!

I agree, but I would like to add:

- The KALLAX side panels are actually replaceable parts. IKEA offers these original replacement pieces, which makes swapping them easier and more reliable than gluing, as the fit is guaranteed.

- When attempting to glue, the coating where the bond must be applied can cause problems. Most PU adhesives cure well on raw wood or MDF but less effectively on laminated surfaces.

- If you still choose to glue, you should consider the mechanical stresses on the repaired area. Especially under bending or lateral pressure, the glued joint may fail.

- A note: If you want to replace the panel, you don’t need to replace the entire shelf unit, only the side panel. These parts are available exactly as needed in IKEA’s inventory.

My recommendation: For the damaged corner, I would prefer replacing the panel for durability and appearance. A glued area will remain visible, especially on exterior surfaces.

It is important to highlight this so you can make a decision based on facts.

Grahame48, I really appreciate how thoroughly you have researched this topic and looked for possible solutions.

That made me think. I once had a similar problem and used glue – honestly, it didn’t look very neat, even though I tried my best. If that bothers you, it might not be visually satisfying.

On the other hand, replacing a fresh side panel only costs a few euros and some effort, but ultimately feels more professional and you don’t have to worry about stability or durability.

Best regards and good luck with the repair!
