Hello everyone, I am planning to change the color of my BILLY shelves and want to paint them instead of just covering or staining them. I am especially interested in tips on the right type of paint, surface preparation, and whether you have experience with the durability of different paints on this specific furniture. The shelves are made of powder-coated particleboard and have a smooth surface. I am wondering if a special primer is necessary and what the entire painting process should look like to achieve a durable and high-quality result. Perhaps someone has painted BILLY shelves before and can share their approach and any potential challenges. Thank you in advance for your expertise!
Hello Jessie42, your question about painting the BILLY shelves is very well thought out, which I appreciate. I’ll go into some detail to give you a truly solid guide.
First: The surface of the BILLY shelves is usually made of melamine-coated particleboard. This means you’re dealing with a very smooth and durable surface that can’t just be sanded and painted over. If you paint directly on it without pre-treatment, the paint usually doesn’t adhere well or bubbles can form.
Therefore, it’s important to first scuff the surface lightly with fine sandpaper (grain 180-220) to improve adhesion. After that, thoroughly remove the dust—ideally with a damp cloth—and then let it dry completely.
Before applying the actual paint, I recommend using a special adhesion primer suitable for plastics or melamine-coated furniture. This primer ensures that the paint sticks better later on and doesn’t chip off.
For the paint itself, I suggest water-based acrylic paints because they have low odor and are relatively environmentally friendly. Depending on how much wear and tear the shelves will face, you can also use polyurethane (PU) paints, which are very durable but usually have longer curing times.
Apply the paint ideally with a spray gun or a high-quality foam or paintbrush in thin, multiple coats. After each coat, lightly sand again (for example, with 320-grit sandpaper) and remove dust thoroughly. This method will give you a smooth, nice finish.
If you want to use highly opaque colors, additional intermediate coats may be required. It’s also important to let the shelf dry in a dust-free environment.
One more question for you: Do you want to paint just the outside or also the inside of the shelf? Do you have a preference for the finish (matte or glossy)? Depending on that, the choice of products can be adjusted.
This is important for the preparation—as without thorough intermediate sanding and primer, nothing will stick properly. Melamine-coated surfaces are specifically designed to be scratch- and moisture-resistant, which makes painting a challenge.
If you need more details on the application, I’m happy to help. 🙂

Dilen has already summarized the key points very thoroughly. I would like to add that when purchasing the primer, you should ensure that it is explicitly suitable for challenging substrates such as melamine or plastic. Not every primer works equally well when it comes to furniture with smooth surfaces.
Additionally, I recommend thoroughly cleaning the BILLY shelves before treatment. A mild alcohol-based solvent—such as a little methylated spirits on a cloth—is suitable for removing any greasy residues that could otherwise impair adhesion.
Regarding the paint: if you want a particularly durable result, I would recommend a two-component lacquer, which is more labor-intensive but becomes very robust. For home use and less frequently used furniture, however, a high-quality acrylic paint is usually sufficient.
Finally, patience during drying and curing of the paint pays off. Even if the result looks good after the first day, especially polyurethane (PU) lacquers need enough time to fully cure, otherwise there is a risk of scratch marks or discoloration from use.
Do you already have a specific paint or finish in mind? Maybe I can also offer some recommendations on that.

Hey Jessie42 and everyone else,
I just want to bring a bit of a relaxed vibe here and share some of my experience, because painting BILLY shelves is actually a pretty nice challenge. 🙂
I think especially with shelves, multiple thin coats are worth it because one thin coat can look uneven, and once you get the hang of it, it’s almost fun. Tip: Try controlling the amount of paint your tool holds on a corner or a piece of cardboard first – it’s not a race, rather a slow stroll.
Also: Do this on a warm, well-ventilated day and make sure to take breaks in between. You can carefully wipe off any paint splatters with a slightly damp cloth as long as the paint hasn’t fully hardened yet.
By the way, if you’re feeling brave, you can even use fine sanding fleece between coats; it removes excess shine and results in a truly professional finish.
I agree — nothing is more frustrating than a freshly painted shelf that gets ugly scratches because you were too impatient. So: Have another coffee and wait a bit, then everything will be perfect. 😉
Have you used any special paints for living rooms or children's rooms? I like glossy finishes in dark tones, they reflect light so nicely in small spaces.
