Klashaya357 Oct 2020 08:13Good morning everyone, I am currently looking into how to improve the durability of Malm paint. Specifically, it concerns the IKEA Malm that I want to repaint. The problem is that the paint often peels off or shows unattractive signs of wear after some time, even though I have applied several thin layers. I am especially interested in recommendations for surface preparation, primers, types of paint, or sealants that can make the surface particularly durable and resistant to scratches, moisture, or UV exposure. Are there any proven products or techniques for Malm paint? What experiences have you had? I look forward to detailed tips and also advice on what to avoid.
Hello, I’d like to provide you with a brief guide on how to improve the durability of Malm lacquer:
1. Preparation: Remove all old paint residues or sealants. If the Malm is made of MDF, it is recommended to sand lightly with 120-150 grit sandpaper to ensure good adhesion.
2. Primer: Use a high-quality sealing primer, specially designed for MDF or wood, to prevent swelling caused by moisture and to help the paint layers adhere properly.
3. Paint application: Use acrylic paints, as they are flexible and durable. Apply several thin coats, sanding lightly between layers with very fine sandpaper (240-320 grit) to smooth out any imperfections.
4. Sealing: For extra protection, a clear coat that is UV-resistant and scratch-resistant, such as polyurethane clear coat, is recommended. This usually significantly improves durability.
Mistakes to avoid:
- Applying paint layers that are too thick, as they tend to crack quickly
- Insufficient drying times
- Not using a primer
I hope this helps you.

Could you be a bit more specific about what type of clear coat would be suitable for this? I always feel overwhelmed by all the different options when buying materials. Are there particular manufacturers or specifications to look out for? Also, what about water-based versus solvent-based coatings? Is there a noticeable difference in terms of durability and environmental impact?

Hello, I’d like to add some information about clear coats.
PU clear coats (polyurethane) are indeed very durable, providing strong protection against mechanical wear and moisture. However, they contain solvents and have a stronger odor, which can be unpleasant in smaller rooms or apartments.
Water-based coatings are more environmentally friendly and dry faster, but they often take longer to fully cure and may not always offer the same level of durability as PU coatings.
A good compromise nowadays are 2-component water-based coatings, which combine both advantages: they are eco-friendly, relatively low in odor, yet still highly resistant.
Also, pay attention to specifications such as “scratch-resistant,” “UV-resistant,” and “suitable for furniture” when choosing a product.
In general, I would recommend a multi-layer application with intermediate sanding for surfaces subjected to heavy use, as this significantly improves durability.
