ᐅ Painting KALLAX with spray paint – does it cover well?

Hello everyone,

I’m planning to paint my KALLAX shelving unit from IKEA using spray paint and wondering how good the coverage usually is for a project like this. I’ve read that the surface of the KALLAX is quite smooth, which might make painting more difficult – the paint could apply unevenly or be thin in coverage.

Has anyone had experience with this and can say if spray paint alone is enough, or if it’s better to sand the unit beforehand or use a primer? Also, how many coats should be applied at minimum to achieve a fully opaque and durable finish?

I would also appreciate any tips on suitable spray paints and techniques. Thanks in advance!

Regarding the question: "Spray painting KALLAX – does it cover well?"

KALLAX boards have a melamine-coated surface that is very smooth and hard. This prevents spray paint from adhering well without prior treatment. Based on personal experience and material knowledge, I strongly recommend lightly sanding the surface with 220-grit sandpaper before painting to roughen it up.

Additionally, using a primer (promoting adhesion) is advisable, as using spray paint alone rarely achieves an even and durable topcoat.

For spray paint, 2–3 thin coats are preferable, allowing each coat to dry thoroughly. Thick coats tend to cause runs or an uneven appearance.

My recommendation is a special synthetic resin primer followed by a high-coverage acrylic or synthetic resin spray paint. Cheap spray paints often have lower coverage and durability.

Absolutely! If you try to apply one thick coat, you’ll end up with thick, running spots.

I once upgraded a KALLAX unit with spray paint – first sanded it, then painted it in the warm garage, and the coverage was excellent. The trick: use paint suitable for plastic, otherwise it won’t adhere well.

And hey – if needed, just gently sand between coats with fine-grit sandpaper; this results in a smooth finish like a factory paint job. 🙂

Don’t forget: ventilate regularly and allow enough drying time, or the result won’t turn out well.

Regarding the coverage of spray paint on KALLAX, I would like to add a few details.

First: The melamine-coated surface is very durable, correspondingly smooth, and chemically inert. This means adhesion is limited without preparation.

Sanding with 220 to 320 grit sandpaper (fine grit) is sufficient to roughen the surface without damaging the wood panel. Afterward, a primer specifically designed for plastics or melamine is recommended.

Second: The choice of spray paint greatly influences the result. Two-component spray paints or synthetic resin paints are well suited for furniture because they offer strong coverage and remain durable after curing. Acrylic paints are easier to work with but generally less resistant.

Third: Apply several thin layers (at least 2-3, depending on the paint and opacity), allowing 10-15 minutes drying time between coats.

Additionally, I recommend sealing with a matte or satin clear coat (also available as a spray) after the final layer to protect against scratches and wear.

One last question for you: What type of spray paint were you considering? That could help narrow down the recommendations.

Thank you for the detailed answer. I was actually thinking of using an inexpensive acrylic spray paint, like the ones available at hardware stores. It should be as simple and affordable as possible, but if I can’t achieve the desired coverage and durability with that, I would consider your recommendation.

The goal is a fully opaque, matte white finish that looks clean and is as resistant as possible to scratches and wear. Do you or anyone else have experience whether cheap acrylic paints for furniture are sufficient, or if it is better to use two-component (2K) or synthetic resin paints?

Also: After sanding, is it absolutely necessary to apply a primer, or is it enough to thoroughly degrease the shelf beforehand and apply the paint carefully?

In this case, applying primer is not just recommended but almost essential, especially if you want to achieve optimal adhesion and coverage.

The melamine surface of KALLAX is water- and dirt-repellent, which also means that paint without primer is more likely to peel or adhere unevenly.

Degreasing is necessary, but on its own it is not enough. The primer also ensures that the paint not only sticks better but also develops fewer peeling spots or cracks during and after drying.

For a matte white finish, a bonding primer specifically designed for smooth surfaces is advisable.

If you are using a cheap acrylic spray paint, you should definitely prime beforehand; otherwise, the result often looks patchy and lacks durability.
