ᐅ KALLAX unit corners damaged upon moving in – repair instructions?

Hello everyone,

I recently moved into a new apartment and noticed some damage to the corners of my KALLAX unit (the shelf with square compartments) while assembling it. The corners are scraped on two sides and have cracks, probably caused during transport or handling during the move. Since I really want to use the unit, I am looking for a practical repair guide on how to best fix these corner damages without significantly affecting the appearance.

Are there established methods you can recommend for repairing corners like this, for example using special fillers, sanding, painting, or even specific repair kits for KALLAX? Is it necessary to replace individual parts, or can such damage be repaired discreetly by myself?

I look forward to your experiences, tips, and suggestions on the best approach so I don’t have to discard the shelf. Many thanks in advance!

The corners are worn down on two sides and have cracks, probably caused by transport or handling during the move.

In such cases, I recommend first gently cleaning all damaged areas and carefully removing any loose parts. For repairing corners, special wood filler or furniture repair compound is suitable, which can be sanded and painted over after it hardens.

There are also repair kits available on the market specifically designed for MDF or particleboard panels like those used in KALLAX. Using fine sandpaper with a grit of 180 to 220, you can smooth the surface. Afterwards, matte acrylic paint in a matching tint can be applied sparingly to visually blend the repaired area.

A complete replacement of the damaged cabinet parts is usually labor-intensive and only necessary in cases of very large or structurally significant damage. For small to medium damage, these steps are generally sufficient and effective.

Great that you’re reaching out here instead of just giving up on it! 🙂 I once had a nasty scratch on my KALLAX and fixed it with wood filler from a hardware store. The product dries quickly and can be sanded smoothly afterwards. Just add a bit of paint, and you’re done!

This is brilliant because it lets you save your shelving unit nicely and, at the same time, you get a little DIY story to share about your move ;-)

Really: just give it a try and don’t get discouraged right away!

Additionally: If the damage is quite deep, it is advisable to apply several layers of wood filler one after another. After each layer, allow sufficient drying time before sanding and applying the next layer.

It is also important to touch up the repaired area with a suitable acrylic paint or furniture touch-up pen in the exact finish and color of the cabinet to achieve the best visual result. Sometimes there are slight color variations with KALLAX units. A good tip is to test the matching color in an inconspicuous spot first.

Apply furniture filler, sand it smooth, and then paint with a matching color – this will neatly repair the corner.

Do not apply too thickly, as it can quickly look bulky.

The tip about using wood filler is generally good, but don’t you think that common wood fillers sometimes don’t adhere well to MDF panels like those used in KALLAX? The surface is often coated with melamine, which can sometimes prevent an optimal bond.

I would rather recommend technical repair kits specifically designed for melamine-coated furniture. These have adhesives or fillers formulated to ensure lasting durability and better appearance.

Has anyone found success with such kits? What are your experiences, and are there differences in product quality?
