How Low-VOC Paint Improves Indoor Air
Share
Indoor air can be more polluted than outdoor air, with VOCs (volatile organic compounds) from regular paints being a major contributor. These chemicals release harmful gases that linger for months, affecting health and increasing risks of respiratory issues, headaches, and even long-term organ damage.
Switching to low-VOC paints reduces these risks. These paints contain fewer harmful chemicals (less than 50 g/L of VOCs), improving air quality while being safer for families, especially those with asthma or allergies. They also have less odour and are better for the environment.
Key Takeaways:
- Low-VOC paints: Emit fewer harmful chemicals, improving indoor air quality.
- Health benefits: Safer for children, elderly, and those with respiratory conditions.
- Environmental impact: Lower emissions reduce pollution.
- Performance: Comparable to regular paints in durability and coverage.
By choosing low-VOC paints, you create a healthier and safer living space while reducing harmful emissions.
What Are Low-VOC Paints?
Definition and Key Features of Low-VOC Paints
Low-VOC paints are designed with significantly fewer volatile organic compounds (VOCs) compared to traditional paints. To put it into perspective, standard paints typically contain around 250 g/L of VOCs for matte finishes and up to 380 g/L for glossy finishes. In contrast, low-VOC paints usually have 50 g/L or less, while no-VOC paints contain as little as 5 g/L or less. In Australia, low-VOC paints are defined as having no more than 49 g/L of VOCs, with some brands offering even lower levels.
The key difference lies in their formulation. Low-VOC paints are often water-based, using water-based resins instead of the oil-based resins found in traditional paints. This shift reduces the need for chemical solvents. Traditional paints rely on VOC solvents to maintain a "wet-edge" during application, whereas low-VOC alternatives achieve this with fewer chemicals. The result? Shorter drying times, although they may sometimes require an extra coat for full coverage and can produce a slightly streaky finish. On the plus side, these paints emit a much milder odour, making them more pleasant to work with.
This updated composition not only limits chemical exposure but also contributes to safer indoor environments.
How Low-VOC Paints Improve Indoor Air Quality
Thanks to their reduced chemical content, low-VOC paints help improve indoor air quality by releasing far fewer harmful substances into the air. Traditional paints, on the other hand, emit VOCs that evaporate into your living space, causing indoor pollution. In fact, in newly built homes, indoor VOC levels can be several times higher than outdoor levels. By cutting down on these emissions, low-VOC paints help minimise health risks such as headaches, nausea, and respiratory problems that are often linked to high VOC exposure.
This benefit is particularly relevant in Australiaโs warm climate, where higher temperatures can speed up the release of VOCs from traditional paints. Choosing low-VOC paints is a simple yet effective way to create a healthier home environment, all while maintaining reliable performance.
Health and Benefits of Low-VOC Paints
Health Benefits for Your Household
Low-VOC paints bring significant health advantages to Australian households by reducing harmful chemical emissions. This translates to cleaner, safer air for everyone, from young children to the elderly.
Traditional paints often release chemicals that can irritate the respiratory system, causing coughing, throat discomfort, and other symptoms during and after application. In contrast, low-VOC paints are much gentler on the lungs, making them an excellent choice for families with asthma sufferers or anyone prone to respiratory issues.
For those sensitive to chemicals, these paints are less likely to provoke allergic reactions or other discomforts. Over time, limiting exposure to high levels of VOCs can reduce the risk of chronic respiratory diseases, nervous system disorders, and even some types of cancer. Since certain VOCs are known to be neurotoxic, cutting down on their presence also offers long-term protection for the nervous system.
Additionally, low-VOC paints can improve comfort and even promote better sleep, especially when used in spaces like nurseries or childrenโs bedrooms. These benefits not only enhance individual well-being but also contribute to healthier living environments overall.
Impact on the Environment
The advantages of low-VOC paints extend well beyond personal health, offering meaningful benefits for the environment as well. By releasing fewer volatile organic compounds into the air, these paints help reduce air pollution and improve outdoor air quality for entire communities. VOCs are a contributor to ground-level ozone, which negatively impacts both human health and local ecosystems.
Many manufacturers of low-VOC paints also prioritise sustainable practices. For instance, some use renewable resources and aim to lower energy consumption during production. Dulux Australia, for example, has taken steps to reduce its carbon footprint by installing solar power systems across its Dulux Trade Centre stores and implementing other eco-friendly measures like rainwater harvesting and wastewater management at its manufacturing sites.
Low-VOC paints often incorporate biodegradable ingredients, making them less harmful to the environment when disposed of. For Australians committed to sustainability, these products align with green building initiatives and meet standards set by organisations like the Green Building Council of Australia. Local manufacturers are also innovating with plant-based paints and sustainable packaging, such as using recycled materials and cutting down on plastic, further reducing ecological harm.
Tips for Choosing and Using Low-VOC Paints
How to Identify Certified Low-VOC Products in Australia
When you're shopping for low-VOC paints in Australia, check the product label to ensure the VOC content is listed as less than 50 grams per litre. This is the standard for paints to qualify as low-VOC.
Certifications are a reliable way to ensure quality and adherence to environmental standards. In February 2025, Premier Painting Company in Sydney highlighted the importance of certifications like Green Star and GECA when selecting low-VOC paints for commercial applications.
Here are three key certifications to keep an eye out for:
- GECA (Good Environmental Choice Australia): Indicates the paint meets strict environmental criteria.
- Green Star: A trusted mark for sustainable building materials.
- Sensitive Choice: Endorsed by the National Asthma Council Australia, ideal for those with asthma or allergies.
Several major paint brands in Australia carry these certifications. For instance, Dulux envirO2 is GECA certified, while Taubmans Pure Performance is endorsed by the Sensitive Choice programme. Resene also offers a full range of low and zero-VOC paints, all certified by GECA.
Water-based (acrylic) low-VOC paints are another excellent choice. They're safer, easier to clean, and typically have lower VOC levels than oil-based paints. Plus, they dry faster, which is a bonus for Australian households looking to minimise disruption during home projects.
Once you've selected the right certified product, the way you apply it plays a big role in achieving the best results.
Best Practices for Application
To fully enjoy the health and environmental benefits of low-VOC paints, proper preparation and application are essential.
Start by cleaning all surfaces with a mild detergent to remove dust and dirt. For greasy areas, especially in kitchens, use a stronger degreaser to ensure the paint adheres properly. Fill any holes or cracks, then sand the surface smooth. Apply painter's tape along edges, trims, windows, and doors for clean lines. If you're painting over dark or new surfaces, use a primer to ensure an even finish.
Ventilation is key during application. Even though low-VOC paints emit fewer harmful chemicals, keeping windows open and using fans helps with air circulation. This speeds up drying and improves indoor air quality.
Match the paint to the room's specific requirements. For kitchens, go with moisture-resistant, low-VOC paint in a semi-gloss finish, which makes cleaning easier. Haymes Paint Kitchen & Bathroom is a great option that resists bacteria, mould, and mildew. Bathrooms benefit from similar semi-gloss or gloss finishes with added moisture resistance. Wattyl I.D Advanced is a solid choice for its anti-mould and anti-bacterial properties.
Bedrooms are best painted with an eggshell finish in a low-VOC formula to maintain cleaner air. For nurseries and kids' rooms, zero-VOC paint is the safest option. One family in Marrickville, Sydney, used eco-friendly, low-VOC paint in their nursery before their baby arrived. The result? A beautiful room with no odour complaints, and peaceful nights for everyone.
High-traffic areas like hallways and entryways require durable finishes that can withstand frequent cleaning. Satin or silk paints are ideal here, as they hold up well to wear and tear while maintaining their appearance.

Why Low VOC Paints are Worth the Money
Low-VOC vs Regular Paints: A Comparison
Understanding the differences between low-VOC and regular paints goes beyond just their chemical makeup. Itโs about how they impact your health, the environment, and even your budget. Letโs break it down.
Traditional paints pack a heavy VOC punch. Regular paints can contain up to 250 g/l of VOCs in flat finishes and 380 g/l in gloss, satin, and semi-gloss varieties. Whatโs concerning is that these VOCs donโt just disappear after the paint dries - they keep releasing into the air for a long time.
The consequences are far-reaching. Regular paints significantly contribute to indoor air pollution, which costs Australia an estimated A$12 billion annually in lost productivity and health issues. In fact, VOC levels indoors are typically two to five times higher than outdoors, largely due to emissions from paint.
Low-VOC paints offer a cleaner alternative. These paints are formulated with less than 50 g/l of VOCs for flat finishes and under 100 g/l for satin, semi-gloss, or gloss finishes. Thatโs about 80% fewer harmful chemicals compared to traditional paints, making a big difference for both health and the environment.
