Hello everyone, I am planning to install new IKEA Platsa furniture in a room that occasionally experiences some moisture due to an adjacent terrace – especially after rain and during periods of high humidity. Since PLATSA is mainly made of particleboard with a foil coating, I am concerned about swelling edges and the overall durability of the furniture under these conditions.

Does anyone have experience or proven methods for effectively protecting PLATSA furniture from moisture without affecting the appearance or damaging the furniture? I am thinking of possible sealants, undercoating, or other technical solutions. It is particularly important to me that the furniture remains flexible and is not restricted in its assembly by too rigid protective layers.

Thank you in advance for your tips and advice!

The concern about moisture with PLATSA is justified, as the base is made of particleboard, which is susceptible to swelling if water penetrates the edges. My advice is to first treat all cut edges of the furniture with a waterproof wood sealant before assembling the pieces.

Additionally, it is recommended to use furniture feet or suitable pads to prevent direct contact with a damp floor. An extra sealing of the back panels and base edges of the furniture can help reduce moisture ingress.

As an addition: The particle boards in the PLATSA system are melamine-coated, which primarily provides surface protection. The weak points are actually the unsealed edges and possibly the assembly holes. To improve moisture resistance, in addition to waterproof sealing with paint or seam sealers, a permanent elastic coating with liquid rubber can also be applied.

Careful preparation is essential, meaning protecting the edges from moisture, and during use ensuring adequate air circulation to prevent condensation inside the furniture.

Another option is to avoid placing furniture directly against exterior walls, as these can promote cold and moisture exposure. It is also advisable to leave gaps between the wall and the furniture to allow air circulation, which reduces moisture buildup.

Additionally, using devices such as dehumidifiers or mechanical air exchangers in the room can be helpful, especially if the terrace is used frequently or the outside air is often humid.

During installation, a polyethylene (PE) sheet can be placed under the furniture to prevent potential rising moisture damage from the floor.

I would recommend sealing all cut edges with acrylic lacquer and placing the furniture on feet. This significantly reduces the risk of moisture damage.

Acrylic lacquer is good, but I specifically recommend a waterproof version, as standard acrylic lacquers do not always provide sufficient moisture resistance. Multiple coats with sanding between layers also improve the protective effect.
