ᐅ How can Malm furniture be better protected against moisture?

I would like to start a discussion with the specific question: How can the Malm furniture series from IKEA be better protected against moisture?

I have noticed that especially in rooms with higher humidity—such as bathrooms, kitchens, or basements—the Malm furniture tends to swell quickly or the surfaces suffer. The construction with particleboard and veneered surfaces is attractive and affordable, but this is precisely what makes it vulnerable.

I am particularly interested in practical and effective methods, such as coatings, additional protection, or other measures that prevent the furniture from absorbing moisture and keep it stable over time. It would also be important to address any potential risks, such as the effects of sealants or chemical treatments on the appearance and environmental impact.

Does anyone have experience, specific tips, or recommendations that go beyond general advice? Suggestions for products or modifications that can be done by oneself are also very welcome.

Simply seal the surfaces with clear varnish; this prevents water from penetrating.

Otherwise, avoid placing furniture in very damp rooms—that is the best protection.

Basically, the issue is that Malm furniture is made from coated particleboard, which can absorb moisture at the edges and surfaces despite being covered with foil or melamine laminate, especially when exposed to humid air or direct splashes of water.

An effective approach starts with protecting all sensitive cut edges, where water can easily penetrate. Special edge sealants made of transparent acrylic or waterproof varnishes are helpful here. These must be applied cleanly and without hairline cracks, ideally in several layers with sufficient drying time between applications.

For the surface, an additional clear lacquer or water-repellent furniture wax is recommended. It is important to choose products that remain breathable so that moisture does not accumulate inside the board, which could otherwise cause blistering or delamination.

Furthermore, it makes sense to physically separate the furniture from the moisture source—meaning keeping some distance from the wall, ensuring good ventilation in the room, and, if necessary, using a dehumidifier.

Regular maintenance and inspection are also crucial because even the smallest defects in protective layers can quickly allow moisture to penetrate.

I am interested in how severe the exposure is and in what environment the furniture is located. That would help to recommend targeted measures more effectively.

You’re touching on an important point! People often underestimate that not only direct moisture is damaging, but also generally high humidity. If you place a Malm shelf unit in the bathroom and leave the door open while showering, you’re basically inviting swelling and warping.

Of course, this can’t always be avoided completely, but you can achieve a lot with simple measures. Using spacer feet or small plastic pads under the legs to prevent moisture from wicking up through the floor into the furniture is an inexpensive hack.

Applying moisture-resistant varnishes or sealants can also make the furniture carcass more durable, without having to retrofit your furniture in a workshop.

It’s also important to ventilate regularly and monitor the room’s humidity with a hygrometer. If you’re a bit handy, you can add sealing tape to edges to prevent water from penetrating joints.

In any case: Don’t be afraid of attentive care! Your furniture will thank you with a longer lifespan. 🙂
