Hello everyone, I have a few Malm furniture pieces with some small damaged areas and edges. My question is: which adhesives are best suited for repairing Malm furniture, especially when it comes to cleanly and permanently gluing broken edges or cracks? It is important to me that the glue remains as invisible as possible, penetrates well into the rather smooth veneer material, and does not cause discoloration. Additionally, the repairs should be durable for everyday use without being noticeable. Does anyone have experience with suitable adhesives or can recommend specific products? Thanks in advance for your help.
Choosing the right adhesive for Malm furniture is crucial because the surface is usually coated with melamine resin, which is not very porous or absorbent. Wood glue designed for pure wood bonding works well for wood itself, but it tends to adhere poorly to melamine since this surface is very smooth and non-porous. Therefore, I recommend lightly sanding the bonding surfaces with fine sandpaper (grit 220 to 320) beforehand to improve adhesion.
Alternatively, special polyurethane-based construction adhesives (PU adhesives) are suitable. They provide strong bonding, remain flexible, and adhere well to smooth surfaces.
Additionally, a two-component epoxy adhesive can be useful for small cracks or broken edges, as it is very strong and durable. However, attention should be paid to the viscosity to prevent the adhesive from running too much and becoming visible later.
Have you already checked whether the surface is really melamine or possibly veneered MDF? This can sometimes be a decisive factor when choosing the adhesive.

Regarding liability for Malm furniture: These items are often made from particleboard with a melamine coating, which is hardly porous. Therefore, roughening the bonding surfaces is the most important step before applying wood glue or other adhesives.
I can confirm that. Polyurethane adhesives provide a good bond on coated surfaces, but they are not always thin or colorless enough to achieve invisible repairs.
It should be noted here that photovoltaic panel adhesive often does not adhere permanently to melamine without careful surface preparation.
For your goal—making invisible repairs on Malm furniture—I would recommend a combination of light roughening and a solvent-free, clear-drying PU adhesive. Additionally, fine sandpaper and possibly touch-ups with suitable retouching paints can be used.

white wood glue (photovoltaic panel adhesive). It is good for veneers, dries clear, and holds well.

For larger breaks, a two-component epoxy adhesive is recommended. This fills small gaps and cures very hard. Especially on edges, this can create a strong connection.
For smaller cracks or chips, solvent-free PU adhesives are ideal. Although they are somewhat more difficult to apply, they remain elastic and highly durable.
Important: After gluing, securely fix the parts and let them rest for at least 12 hours. The ambient temperature should also not be too low.
Can you also specify how large and deep the damages are? This helps to better assess which adhesive is most suitable.

Thank you for the helpful comments. Most of the cracks are quite narrow; some small chips along the edges probably occurred during transport. The surfaces are all smooth and melamine-coated, so some sanding will definitely be necessary. Two breaks involve larger shards that I want to reassemble precisely at the corners, making sure the glued joints remain invisible.
It is important to me that the adhesive does not yellow while drying or damage the surface, as I want to preserve the typical surface texture. I’m concerned that PU (polyurethane) adhesives might swell too much or be too viscous to work with neatly. Epoxy adhesives seem manageable, but can anyone share their experience regarding whether they dry invisibly enough? Also, how flexible are they for everyday use?
I would appreciate further assessments or tips, especially concerning specific products.
