ᐅ Doubling Kallax Doors – Is It Possible Without Screws?

Hello everyone, I am considering adding extra doors to my IKEA Kallax shelves by "doubling" them—that is, attaching a second, thinner door onto the original one to change the appearance or increase stability. Now my question is: Is it possible to double up Kallax doors without using screws? I want to avoid damaging the doors or weakening the shelf by screwing into it. Are there adhesive systems or special techniques that can achieve this, or is it generally unrealistic? I would appreciate any tips or experiences!

Doubling Kallax doors without screws is possible, but only with strong mounting adhesive or double-sided specialty tape. Make sure the door surfaces are completely clean and free of grease. However, screws provide a more stable connection.

The idea of doubling doors without screws is generally feasible; however, I would recommend using high-quality adhesives, such as specialized wood mounting glue. It is important that the doubled doors are not too heavy, as the adhesive bond might fail over time. Alternatively, you could consider concealed screws or small nails that minimally damage the material.

That may be true, but the question remains how durable and load-bearing such a connection is, especially if the door is opened frequently. Do users have experience with the longevity of these adhesive joints? I would assume that screws or at least mechanical fasteners are more robust, particularly because the doors are moved and subjected to stress.

I would be cautious with that. Kallax material is usually MDF with a laminate coating. It has limited load-bearing capacity when it comes to screws. In other words, hidden screws are more likely to cause cracks. Using adhesive can be more effective here, provided you choose the right products. The main factors are weight and stress.

I have addressed this topic several times and would like to provide a structured overview:

1. Preparation: Thoroughly dust the doors and lightly sand them to improve adhesion.
2. Adhesive: A polyurethane or hybrid adhesive is strong and flexible enough for wood and MDF.
3. Fixing: First apply the adhesive, then clamp or press with clamps until the adhesive is fully cured.
4. Load: Doors should not become too heavy; otherwise, additional supports are recommended.

A common mistake is insufficient clamping or using the wrong adhesive. Screws can provide support but are not necessary if the bonding process is done correctly.
