Hello everyone,
I have several Billy bookcases from IKEA in my apartment. Unfortunately, the room sometimes becomes a bit humid, especially during the colder months. My question is therefore: What is the best way to effectively protect my Billy bookcases from moisture to prevent damage such as swelling or warping? Are there specific methods, treatments, or protective measures that work well for these shelves? I would appreciate tips on prevention as well as practical guidance for existing protection, ideally including recommendations for materials that are safe to use and do not affect the appearance of the bookcases.

cassandra30 May 2021 08:23On the topic of moisture protection for BILLY shelves from a technical perspective:
The melamine-coated particle boards are highly sensitive to water vapor and standing moisture. Especially unprotected cut edges tend to swell.
Therefore, I recommend sealing the edges with a suitable clear varnish (polyurethane) and avoiding direct sources of moisture such as wall contact in damp conditions or placing the shelves above a heater without air circulation.
This is crucial, as these areas are usually the weak points.
Additionally, I have found regular shock ventilation very helpful to prevent mold growth in the room.

One more quick question for the original poster: What is the average indoor humidity level in your room? And are the shelves placed directly against the wall, or is there something in between?
This affects the choice of protective methods.

Thank you for the many helpful suggestions and detailed tips.
The average indoor humidity in winter is often between 55 and 65%. The shelves are usually placed along the exterior walls but with about 5 cm (2 inches) of space from them, as I thought this would allow air to circulate.
I don’t have a dehumidifier yet, but that’s a good idea.
However, the advice about applying paint or sealant to the cut edges is causing me some concern. How exactly should I proceed with that? Is a single application enough? What about the visibility on the white surface?
I would appreciate any further explanations!

SauDietmar31 May 2021 07:16Hello jonnar,
regarding your question about applying paint to the cut edges:
It is recommended to apply at least two thin coats. Let the first coat dry thoroughly before applying the second (at least 2 hours). If necessary, lightly sand the surface with fine sandpaper (grit 220) before the second coat to improve adhesion.
Since the paints are usually clear, the change is minimal, but the edges may appear slightly glossier. You can test this beforehand in an inconspicuous area.
Important: Do not use opaque paint, only clear paint designed specifically for furniture or wood.
The 5 cm (2 inches) distance from the wall is good for air circulation – keep it that way. I strongly recommend getting a dehumidifier, as the risk of damage significantly increases above 60% humidity.
Good luck protecting your BILLY shelves! 🙂
