Hello everyone,

I have a Malm wooden piece of furniture where some areas have swollen due to moisture. These are local bulges, mostly on the surface, which significantly affect the overall appearance. My question is: What is the best and proper way to remove swollen spots on Malm wood without damaging the furniture’s structure or surface finish? Are there specific methods or home remedies that provide good results? It would also be important for me to know if these spots can be treated with less effort without having to refinish the entire surface, as only a few small areas are affected. Thank you very much for your tips and explanations!

Hello Bagalis,

To remove swollen areas in pine wood, a careful, gradual approach is recommended:

1. Remove moisture: Place an absorbent cloth (such as a cotton rag) on the affected area and heat it with an iron set to medium heat (without steam). The heat draws moisture out of the wood. Caution: Use only briefly and keep the iron moving constantly to avoid heat damage.

2. Sanding: Once the wood is dry, gently sand the swollen surface with fine sandpaper (grit 220 or finer). Work slowly and evenly to level the area.

3. Aftercare: Seal the treated spot afterwards with an appropriate wood oil or wax to protect the surface again.

This method works well for smaller, localized swelling. If the damage is very large or deep, consulting a professional wood expert might be advisable.

It is important to be cautious when applying heat to prevent further damage.

I hope this helps you.

Hello Bagalis,

As edisondan already mentioned, using a damp cloth and an iron works well to draw moisture out of wood. I’d like to explain this in a bit more detail and help avoid two common mistakes:

First: The iron must not produce steam, otherwise it will push even more moisture into the wood. Set the iron to a medium, dry setting only.

Second: The cloth should not be dripping wet, as this can cause water stains. It’s best to make the cloth just slightly damp.

Detailed procedure:

- Place the cloth on the swollen area.
- Press the iron on the spot for about 10–15 seconds at a time, then move it to another section.
- Check the area regularly to see if the swelling is going down.

If the area is still uneven after treatment, gently sand it with fine sandpaper. Important: Do not sand too deep to avoid thinning the veneer.

Finally, I recommend treating the area with an appropriate wood oil (e.g., linseed oil or a specialized furniture oil) to prevent the wood from absorbing moisture again.

This is crucial; otherwise, the repair can cause even more damage.

Hello Bagalis,

I would like to provide a more basic explanation for everyone dealing with swollen wood. Swelling occurs when moisture penetrates the wood, causing the cell walls to expand. In the case of engineered wood or veneer, as often found in Malm furniture, this is especially noticeable through surface bubbling or warping.

The method mentioned involving the application of heat and removal of moisture is effective because it reduces the water content within the material. The principle is:

1. Absorb moisture (e.g., with a paper or cotton cloth)
2. Apply heat (e.g., with an iron or even a hairdryer, though the iron is often more effective)
3. Allow the wood to dry

Once the surface is flat again, sandpaper can be used to smooth out minor imperfections. For larger damage or detached veneer, however, re-veneering or even replacement may be necessary.

Sometimes I read that people use baking paper instead of a normal cloth because it transfers heat better and releases less moisture – this can be tried with Malm furniture.

This is really important, because too much heat or water can worsen the problem.

Iron using a damp cloth, then allow to dry. Afterwards, lightly sand if necessary. Protect with appropriate oil or wax. Do not iron at too high a temperature to avoid scorch marks.
