Hello everyone, a part of the middle shelf in my Billy bookcase from IKEA has unfortunately broken. It is the thin particleboard, which was probably damaged due to too much weight or rough handling. Now I want to repair it without having to replace the entire shelf. Does anyone have experience with properly fixing such broken parts? I am especially interested in how to stabilize the break points so that the load-bearing capacity is maintained. Materials, methods, and tools that work well would be very helpful.

Roughen the break point with sandpaper That sounds reasonable; I hadn’t considered that. Do I need to sand again after the drying phase if the glue is still visible? How much does this affect the surface if I also want to use the area as a storage spot?
Good question! The surface is slightly roughened at the break point by sanding, which is usually hardly noticeable on a shelf board. After gluing and sanding, you can apply a thin layer of clear varnish to seal and smooth it. This way, the shelf surface remains practically unchanged in usability. Important: Let the glue dry completely before sanding and applying the varnish.
Thank you, Katau! That already helps a lot with the planning. I have an additional question: If a suitable replacement part is not available, is it possible to build up missing pieces using wood filler? Or is that generally unsuitable for load-bearing or stressed parts, such as shelves in Billy bookcases?
