Hello everyone,
I have a small problem with my IKEA KALLAX shelf: the coating is peeling off in some areas. Since I don’t want to simply replace the shelf but try to repair the damaged spots, I’m looking for ideas on how to properly reattach or replace the peeling coating.
It’s important to me that the solution is reasonably durable and doesn’t peel off again quickly. If anyone has experience with specific adhesives, paints, or other materials that work well for this, I would really appreciate any tips.
Also, advice on how to best prepare the surface to ensure the repair holds well would be great.
Thanks in advance!

Before investing too much effort into repairs – how durable is the KALLAX overall? @Joshpe, have you considered whether a minor cosmetic fix is sufficient for appearance, or if the shelf really needs to be replaced?
Often, the effort and materials required for gluing or repairs also depend on the cost-performance ratio. In my experience, for mid-range furniture like KALLAX, functional value outweighs perfect appearance.
If you want to repair it thoroughly without compromise, that’s certainly fine, but I would also compare how resistant other hobby-grade items on the market are to repairs.
Regarding the adhesives: I would like to revisit the question of whether polyurethane glue adheres well to the smooth backside of melamine foil, since melamine is very smooth and chemically inert. Pretreatments with adhesion promoters or primers might help.

In my research, I found that this is often a weak spot during repairs, as the bond there frequently doesn’t last permanently.
Would a solvent-based contact adhesive be a better option? According to product descriptions, it adheres particularly well to foils and plastics.
The key issue for me is to reattach the foil with as little visible adhesive as possible, since I don’t want to completely reapply the foil on the shelving unit, just repair it locally.
Does anyone have direct experience using contact adhesives on furniture laminates?

Would solvent-based contact adhesive possibly be a better choice?Solvent-based contact adhesive actually adheres very well to smooth, coated surfaces such as melamine, laminate, or vinyl films. It creates an immediate strong bond, significantly stronger than many polyurethane (PU) adhesives.
It is important that the adhesive is applied thinly and evenly to both surfaces and allowed to dry properly before joining them together – this is essential for contact adhesives.
A downside of contact adhesives is their somewhat lower flexibility and the strong odor during application. They also tend to be applied in thin layers, so the film needs to lie flat.
For your project (small areas with lifted KALLAX film), contact adhesive might even be the best option if you work carefully.
Please also consider safety: ensure good ventilation and wear gloves, as solvent vapors should not be underestimated.
On the topic of preparation and achieving lasting results:
The most important point that is often overlooked is the absolute cleanliness of the bonding surfaces. For melamine surfaces, degreasing with isopropanol or alcohol can also help remove dust and oil residues.
Contact adhesive adheres excellently if applied correctly and allowed to dry for the recommended time. In my experience, it holds significantly better than wood glue or PU adhesive on smooth, coated surfaces.
After gluing, the repaired area can be treated with a special furniture sealant lacquer—especially on spots that are frequently touched. This increases abrasion resistance.
In cases where the foil is detaching, gently heating it with a hair dryer before repair can help soften the adhesive residues and allow the foil to lie flat again.

In short: Contact adhesive or a special laminate glue is the preferred choice for repairing KALLAX coating.
Only in case of major damage: consider replacing the foil or a complete repaint.
Preparation: degrease the surface, lightly roughen it, apply the adhesive, ensure firm pressure is applied, and allow to cure for 24 hours.
Other adhesives are either too brittle or do not bond permanently to the foil.
