Hello everyone, I unfortunately broke a corner on the carcass of my IKEA Besta cabinet. It is one of the lower corners, and the material is the usual particleboard with a foil laminate. I want to repair the damage as sustainably and securely as possible, without leaving large visible marks afterwards. Does anyone have experience or tips on how to proceed? I'm especially interested in how to properly glue the corner back together and whether additional reinforcements are necessary. I’m also unsure about which type of adhesive is best suited for this and if screws or metal brackets should be used as well. Thanks in advance for any helpful advice!
For repairing a broken corner on an IKEA Besta cabinet, I recommend the following steps:
- Lightly roughen the surface at the break to improve the adhesive’s grip.
- Use a polyurethane (PU) wood glue, as it is very strong and water-resistant.
- Apply the glue evenly to both broken surfaces and clamp the parts together with clamps or grips.
- Reduce any stress on the joint during curing (at least 24 hours).
- After drying, fill any small gaps with wood filler and sand smooth if necessary.
Additionally, for extra stability, you can screw a thin metal bracket on the inside of the corner after gluing if you want the repair to bear more load. However, keep in mind this will leave visible screw holes on the inside surface.
I do not recommend using general-purpose glues or superglues, as they are less suitable for permanent wood repairs in furniture.

Otherwise, moisture can penetrate and cause the board to swell even more. For roughening the surface, it’s best to use fine sandpaper (grit 120 to 180) only on the bonding areas.
If the broken area is very small or heavily delaminated, I recommend gluing small wooden strips or plywood pieces under the corner as reinforcement – this can further stabilize the whole. It is important to firmly clamp the area with clamps so the adhesive can cure completely.
If you want to improve the appearance of the corner, you can use a furniture touch-up marker or paint that matches the color after sanding. This way, any imperfections will be hardly noticeable later.
If you have any further questions, feel free to ask!

Does anyone have experience with disadvantages when using additional reinforcements on IKEA modules?
Furthermore, the question arises whether metal brackets might provide better long-term stability. What about the long-term performance of PU adhesive alone versus the combination of adhesive plus metal brackets? Are there any reliable practical experiences?

The key is that the reinforcements should not be too bulky and must be carefully installed using the same adhesive.

How does the long-term performance of PU adhesive alone compare to the combination of adhesive plus metal brackets?PU adhesive provides a very strong bond, often sufficient for furniture that is not heavily loaded. I usually use metal brackets when additional load is applied to a corner, as they help distribute the load better and provide mechanical support.
In conclusion: If you use the cabinet for heavy loads (e.g., TVs or heavy electronics), a combination of high-quality adhesive and reinforcement with brackets is recommended. For normal loads, adhesive alone and a wooden strip as internal reinforcement are usually enough.
