SopeoHello everyone,
I am considering painting my KALLAX shelf myself, but I have heard that the surface of the shelf is coated, which might make it difficult for paint to adhere. My question is: Is it generally possible to paint a KALLAX shelf that has a factory-applied coating? What preparation work is necessary to ensure that the paint sticks well and does not peel off easily?
Are there any specific tips or experiences with certain paints, primers, or techniques that have proven effective?
I look forward to your expert advice and detailed suggestions – I want this to be a well-considered project, aiming for a long-lasting result. Thank you!

Hello Sopeo,
Regarding your question: Yes, you can paint a KALLAX unit despite its coating, but the preparation is very important.
The surface is covered with a melamine resin coating, which is quite smooth and not very absorbent. This means that without the proper intermediate steps, the paint usually does not adhere well. I recommend the following procedure:
1. Thorough sanding: Lightly sand the surface with fine sandpaper (grit 240 to 320) to create a fine texture.
2. Cleaning: Then clean thoroughly to remove sanding dust.
3. Primer: Use a special adhesion primer designed for smooth surfaces (e.g., synthetic resin-based).
4. Paint: Water-based acrylic paints work well but are less durable. For better durability, two-component (2K) paints or special furniture paints are suitable.
5. Finish: A clear coat can be applied for protection.
Common mistakes include skipping sanding or choosing the wrong primer. I hope this helps you.

From my experience, it’s also crucial not only to remove the sanding dust after sanding but to clean the surface with a degreasing cleaner to eliminate any traces of oils or fats that could negatively affect adhesion.
The choice of primer also matters: synthetic resin primers are often the best option. For the paint itself, you should use a high-quality, flexible furniture paint that can withstand wear and tear.
To add: The coating on KALLAX is usually a melamine resin foil, which is very difficult to grip.
According to technical datasheets for such foils, mechanical roughening is definitely necessary. I also recommend using primers with strong adhesion specifically designed for smooth foils.
These are not standard wood primers but products specially formulated for plastics. It has already been mentioned that sanding between coats before painting is essential – I fully agree with this. Otherwise, the paint may not adhere properly to the surface and could develop cracks or peeling after a short time.

I want to explain this in more detail because the topic is often underestimated.
The typical mistake in such projects is that users simply paint over the melamine coating without any preparation. Melamine resin films, like those used on KALLAX, are hard, smooth, and very resistant.
Step 1: Sanding. You need to be very careful here. Wet sanding with fine sandpaper (e.g., 320 grit) is recommended to create enough roughness without sanding too deep and damaging the film.
Step 2: Degreasing with appropriate solvents—cleaning agents containing alcohol or special degreasers are suitable.
Step 3: Priming. I recommend a bonding primer that is specifically designed for hard-to-paint smooth surfaces, such as an epoxy- or PU-based primer.
Step 4: Painting. Water-based paints are possible but not very durable. For furniture, using a PU paint from a spray can or paint material with good ventilation is advisable.
One more tip: If you are careless during priming, problems such as peeling often only appear weeks later.
A question for you: What will the shelf be used for? Does it need to support a lot of weight?

The shelf will be placed in the living room, mainly for decoration and books, so it won’t be exposed to excessive moisture or dirty items, but it will be used daily.
A clean appearance without peeling or unsightly scratches is important to me.
Could you also tell me if it makes a difference whether I finish it with a brush or spray lacquer? Which method produces a more durable and even result?
