ᐅ KALLAX shelves coming loose after years – how to reattach them?

Hello everyone,

I have an IKEA KALLAX shelving unit that I have been using for about 7 years. Recently, I noticed that some of the shelves are starting to come loose, the joints no longer seem stable, and the whole unit feels a bit wobbly. I suspect that the original dowels and adhesive connections have weakened over time, or that the material has slightly warped.

My question is: What is the best way to reattach the loose KALLAX shelves without taking the entire unit apart or cutting new boards? Are there proven methods, adhesives, or special dowels that work well to secure the shelves safely and permanently?

I want to make as few changes to the original construction as possible, since the unit is otherwise still in very good condition. Has anyone experienced similar KALLAX repairs and can share tips on how to restore its stability? Any advice or instructions would be much appreciated!

If the back panel no longer fits without tension, it should be replaced or re-tensioned

Exactly, this is often underestimated. By the way, the back panel of the KALLAX is just a thin particle board, which can warp over the years. My tip: If you want to replace the back panel, use plywood sheets at least 6mm (1/4 inch) thick, as they are much more stable.

After gluing, clamp and let it dry for at least 24 hours

Definitely stick to that! I’ve heard too many times that people were impatient, loaded the shelves too soon, and then everything became loose again.

And no joke: Screwing small wooden strips to the underside of the shelves can also help improve stability under vertical load. It’s a small modification, but very effective 😉
