How Long Does Paint Smell Last?

When you’re giving your Gold Coast or northern NSW home a fresh coat of paint, one of the most common concerns could be how to deal with that distinctive paint smell that lingers when the job is complete. Whether you’re refreshing your bedrooms on the Gold Coast or renovating an entire beachside apartment in Byron Bay, knowing the answer to the question, “How long does the paint smell last?” is important. As is understanding how to manage persistent odours.

These topics are essential for any Aussie DIY enthusiast as well as for those who hire professionals to handle their interior house painting. Here, we explore factors such as what tends to cause the strong odours, how long paint smells usually last, if they’re dangerous, and other common questions.

What Causes Paint Smells?

Paint fumes mainly come from volatile organic compounds (VOCs) that are released into the air as paint dries, a process called “off-gassing.” These VOCs include various chemicals such as benzene, formaldehyde, acetone, methylene chloride, and toluene, which are added to paint to enhance its performance and durability.

In oil-based paints, the mineral spirits used as solvents are the main culprits behind the strong smell. Water-based paints contain fewer VOCs, which is why they typically smell less potent and for shorter periods.

The concentration of these compounds is highest during and immediately after painting, gradually decreasing as the paint cures and the solvents evaporate. Australian regulations have become stricter regarding VOC content in recent years, leading to the development of low-VOC and zero-VOC options that help to significantly reduce paint odours while still maintaining quality for the long term. If you choose these products, you should find that the paint smells aren’t so strong in your house after work has been done.

How Long Does Paint Smell Last? A Typical Timeline of Paint Odours

How long a paint smell lasts varies depending on several factors, including which paints you use, as mentioned above. You’ll find smells usually go away within the following timeframes:

  • Water-based paints: Generally dissipate within 2-4 days when there is proper ventilation
  • Oil-based paints: Can linger for up to 2 weeks or longer
  • Zero-VOC and low-VOC paints: May clear within 24-48 hours

However, if you’re thinking, “My paint smell will not go away”, keep in mind that factors like humidity, temperature, and ventilation can significantly impact these timeframes. The humidity on the Gold Coast and in northern NSW beachside suburbs, for instance, might extend drying times compared to drier regions found in other parts of the country.

Is The Paint Smell Harmful? Understanding Paint Fumes

The question, “Are paint fumes dangerous?” is a valid concern for many homeowners. While modern paints are safer than ever, paint fumes can, at times, cause:

  • Headaches and dizziness
  • Eye, nose, and throat irritation
  • Breathing difficulties, especially for asthmatics
  • Nausea, in some cases

Vulnerable groups to these paint smells, including pregnant women, young children, and the elderly, should take extra precautions and not spend too long in freshly-painted rooms for the first few days. If you’re painting indoors during a wet winter or summer season, proper ventilation becomes even more crucial, too.

How to Get Rid of Paint Smells: Practical Solutions

Try these effective methods to eliminate paint odours faster inside your property:

Natural Ventilation

  • Open all windows and doors
  • Use cross-ventilation to create airflow
  • Install temporary fans to boost air circulation
  • Consider painting during Australia’s milder months for optimal ventilation

Odour Absorbers

  • Place bowls of white vinegar around the room
  • Use Australian-grown eucalyptus oil as a natural deodoriser
  • Scatter coffee grounds in shallow dishes
  • Light a few nice-smelling soy-based candles in the affected rooms
  • Cut onions in half and place them around the room (an old painter’s trick!)

Technical Solutions

  • Run air purifiers
  • Use air conditioning systems on fan mode rather than circulating the paint smell around your house

Prevention Tips for Future Painting Projects

When planning your next paint job:

  1. Choose low-VOC or zero-VOC paints, which are readily available from hardware and paint stores and used by professional painting firms such as Coverage By Design
  2. Time your painting project during more moderate weather conditions where possible
