That Paint Smell Won't Go Away? Let's Solve It.

Common causes of persistent paint odour

Lingering paint odours can turn the excitement of a fresh coat into a headache. The most frequent culprits include inadequate airflow during drying, painting in high humidity, or applying paint over a dirty or damp surface. Old paint cans, especially those poorly sealed, can also harbour strong smells. Sometimes, the issue isn't the paint itself but what's beneath it, like residual odours from smoke or pets that weren't properly sealed before painting. Understanding these factors is the first step in tackling that stubborn smell.

How paint type (oil vs. water-based) affects smell

The type of paint you choose directly impacts how long and how strong the smell will be. Oil-based paints, often referred to as alkyd paints, contain high levels of solvents that release strong VOCs as they dry and cure. This results in a much more potent and lingering odour compared to water-based (latex) paints. Water-based paints have significantly lower VOCs and primarily release water vapour as they dry, leading to a milder and much shorter-lived smell. Our staff, some with over 20 years behind the counter, can guide you on the best MF Paints product for your project, considering factors like odour, durability, and drying time, ensuring you make an informed choice for your Smiths Falls home.

1. 1

   Boost Airflow

   Open windows and doors. Use fans to create a cross-breeze, directing air out of the room. This helps carry away airborne compounds.

2. 2

   Use Dehumidifiers

   If humidity is high, a dehumidifier can speed up drying and reduce the conditions that trap odours.

3. 3

   Clean Surfaces Thoroughly

   Before painting, ensure surfaces are clean, dry, and free of mould or mildew, which can interact with paint and create new odours.

4. 4

   Consider Odour Absorbers

   Activated charcoal, bowls of white vinegar, or baking soda can absorb lingering smells. Place them strategically around the room.

5. 5

   Seal Unfinished Surfaces

   If the smell is coming from an unfinished surface or a subfloor, sealing it with a low-VOC primer can lock in odours.

Health considerations and when to be concerned

While most paint smells are harmless after initial exposure, prolonged inhalation of VOCs can lead to symptoms like headaches, dizziness, nausea, or respiratory irritation. Individuals with asthma, allergies, or chemical sensitivities are particularly vulnerable. If symptoms persist or worsen, or if the smell is unusually strong and chemical-like, it's wise to ventilate the area thoroughly, leave the space, and consult a medical professional. For future projects, opting for low-VOC MF Paints can significantly reduce these health risks.

Solutions to speed up odour dissipation

Beyond basic ventilation, there are several steps you can take to accelerate the removal of paint odours. Air purifiers with activated carbon filters are effective at capturing airborne VOCs. Placing bowls of activated charcoal, coffee grounds, or sliced onions in the room can also help absorb smells naturally. For stubborn odours, consider an ozone generator, but use it with extreme caution and only in unoccupied spaces, as ozone can be harmful. Ensure all painted surfaces are fully cured; sometimes, what seems like a lingering smell is just a very slow curing process, especially in cooler, damp conditions.

How long does paint smell typically last?

Water-based paints usually lose their strong smell within a few hours to a day after drying. Oil-based paints, however, can emit odours for several days to a few weeks, depending on ventilation, humidity, and the specific product's VOC content. Full curing, where all solvents have evaporated, can take up to a month.

Can paint smell be a sign of a bigger problem?

Occasionally, yes. If the smell is unusually pungent, mouldy, or doesn't diminish with ventilation, it could indicate issues like mould growth under the paint, painting over a contaminated surface, or even a faulty batch of paint. If you suspect a deeper problem, it's best to investigate the underlying surface.

Are low-VOC paints truly odour-free?

While no paint is entirely odour-free, low-VOC (Volatile Organic Compound) paints, like many MF Paints options, have significantly reduced levels of the chemicals that cause strong smells. They typically produce a much milder, less lingering odour that dissipates quickly, making them a better choice for sensitive individuals and for painting indoors.

What if the colour match doesn't look right in my lighting?

We guarantee colour matching accuracy, and if the match isn't right, we will remix it for free. Lighting conditions play a huge role, and our staff in Smiths Falls can advise on how different light sources can affect your chosen colour.
