ᐅ KALLAX Paint Smell – How Long Does It Last?

Hello everyone,
I recently bought a Kallax shelving unit from IKEA and treated it with a clear varnish to make the surface more durable. Now I’ve noticed that the varnish has quite a strong smell – a typical solvent odor that I didn’t expect. My question:

How long does this smell usually last after applying varnish? I have the shelf in a well-ventilated area, but after three days the odor is still quite noticeable. Are there any experiences or tips on how to get rid of the smell faster?

I don’t want to keep ventilating the room for days and then have to live with the strong smell. Maybe it also depends on the type of varnish? Does anyone have similar furniture and experience with varnishing and the related smell? Thanks for your insights!

That depends on the paint! Many people assume all paints smell similar and evaporate quickly. That’s not true! A water-based acrylic paint often only smells for one to two days, while a solvent-based clear coat can easily emit odors for weeks or even months.

The question here is: How good is the ventilation really? Simply airing out the room is rarely enough unless fresh air flows through thoroughly several times a day. And honestly: How sure are you that the smell is coming only from the paint? Sometimes residual solvents can also be trapped inside the wood or glues.

My advice: Patience is key, plus gentle and constant alternating ventilation. Brief or occasional airing out hardly makes a difference.

The smell after painting largely depends on the type of paint used. Solvent-based paints, especially those containing alcohol or turpentine, take longer to off-gas. This can range from one week up to several weeks, depending on the amount applied and the ventilation.

I recommend placing the piece of furniture in a well-ventilated and preferably dry area, ideally with constant air circulation provided by windows or fans. Additionally, room temperature can speed up the off-gassing process, as warmth promotes evaporation.

If the smell remains very strong, it is advisable to check whether the paint is fully dry—carefully reviewing the drying times indicated on the packaging often helps.

The smell can last for up to two weeks or even longer.

Plenty of ventilation and placing it in a warmer spot can help.

If it is too strong, you can try filtering it with activated charcoal or a vinegar smell.

The fact is:

The smell after painting a KALLAX shelf is directly related to the solvents contained in the paint. With solvent-based clear coats, volatile organic compounds form after application, which off-gas over several days to weeks and are perceived as odor.

The typical off-gassing period is between 7 and 21 days but can be significantly affected by factors such as room temperature, humidity, and ventilation. Warm air and constant airflow promote faster evaporation.

In conclusion, comfort and health should not be overlooked. When in doubt, special low-odor paints are more suitable.

Patience is the magic word

Patience, yes, but how much longer should we keep holding our noses before the shelf is finally ready to use?

In my opinion, many manufacturers just want to profit from their products without considering the user. Sure, the smell is toxic and lingers for a long time – but why aren’t low-odor paints the standard when they are technically available?

I think there should be more pressure on the industry, and end users should demand more. Why do we still accept this “standard”? Who knows what we are inhaling because of it. Just because the paint smells bad for a short time doesn’t mean it’s harmless.
