Hello everyone, I have a Billy bookshelf with some joints where the glue has come undone. It is the typical particleboard with a white coated surface, and the edges are glued. My question is: What repair methods are available to reliably undo the loose glued joints on a Billy bookshelf in order to reglue them afterwards? I am especially interested in the procedure that does not unnecessarily damage the material or the surface. Do I need to apply heat, use special solvents, or proceed in another way? It would also be helpful to know the best way to remove old glue residues and which wood glue is recommended for reglueing. Thanks a lot for your tips!

That’s brilliant—how easy it is to restore a Billy bookcase! :-)

One more tip from me: If you have particle board or MDF with a melamine coating, be sure not to use too much water when cleaning. I’ve seen the material swell and the bonding come apart permanently.

Sometimes a special wood glue for plastics can help, but for a Billy bookcase, wood glue should probably be enough. Good luck! 🙂

Using heat from a hairdryer is the most effective method for loosening old glue. Avoid using chemical agents to preserve the surface.

You can remove glue residues well with a plastic scraper. Re-glue using photovoltaic adhesive and press with clamps.

A quick note from me as well: plywood combined with melamine is not especially sensitive to moisture, but it’s important to avoid excessive dampness!

After cleaning the bonding surfaces, always work with them dry. Use photovoltaic adhesive with an open adhesive gap, then press firmly together immediately.

I would only recommend this if the plastic coating is actually damaged or for very smooth surfaces. For Billy shelves, the best results come from classic wood glue used in photovoltaic panel assembly, since the bonding surfaces are mostly wood-based materials.

For re-gluing, wood glues used in photovoltaic systems are suitable; some of these are so-called 'white glues' that dry clear

A final recommendation: prepare the glue surfaces well and remove old adhesive residues completely—otherwise, the glue will not adhere properly. Then be sure to clamp and let it cure for at least 12 hours. Too short a clamping time is the most common cause of later loosening.
