Resene Eco Paint Guide: Low-VOC & Sustainable Options

Paint affects your home's indoor air quality. Choosing eco-friendly, low-VOC products matters for your family's health and environmental impact.

As certified Resene Eco Decorators, here's our guide to Resene's sustainable paint options for Wellington homes.

What Makes Paint "Eco-Friendly"?

VOC Levels (Most Important)

VOC = Volatile Organic Compounds

Traditional paints release VOCs during application and for weeks/months after:

• Cause headaches, respiratory irritation
• Contribute to indoor air pollution
• Environmental impact

Resene low-VOC standards:

• Standard paints: <50 g/L VOCs
• Low-VOC range: <10 g/L VOCs
• Zero-VOC options: <1 g/L VOCs

Compare to older paints (80–150 g/L) — a dramatic improvement. For context, the World Health Organisation classifies many compounds found in high-VOC paints as probable carcinogens with chronic exposure. The shift to low-VOC formulations in professional painting is one of the most significant health improvements in the trade over the past two decades.

Environmental Choice Certification

New Zealand Ecolabelling Trust certification:

• Rigorous independent assessment
• Whole product lifecycle considered
• Manufacturing process evaluated
• Performance standards maintained

Resene has more Environmental Choice certified paints than any other NZ brand — over 550 products. The certification isn't a rubber stamp; it requires documented evidence of environmental performance across manufacturing, packaging, and end-of-life management, reviewed on a regular cycle.

Manufacturing Impact

Resene's approach:

• Waterborne formulations (not solvent-based)
• Local NZ manufacturing reduces transport emissions
• Extensive recycling programme (PaintWise)
• Unused paint return scheme
• Packaging recycling

Resene manufactures in Upper Hutt — practically in Wellington's backyard. Choosing Resene over imported alternatives isn't just about the product; it's about supporting local manufacturing and avoiding the significant carbon footprint of sea freight from Asia or Europe.

Health Benefits of Low-VOC Paint

During Application

Traditional paint:

• Strong odour for days
• Headaches, nausea common
• Need extensive ventilation
• Occupants often leave during painting

Resene low-VOC:

• Minimal odour during application
• No headaches or nausea
• Can remain in home during painting
• Safe for occupied spaces

After Application

Traditional paint:

• Off-gassing continues weeks/months
• Indoor air quality affected long-term
• Particularly problematic in winter (homes closed up)

Resene low-VOC:

• Minimal off-gassing
• Room usable immediately after drying
• Long-term indoor air quality maintained
• Safe for children, elderly, sensitive individuals

Wellington's cold winters mean homes are often closed up for months at a time. In a sealed house during July and August, VOC off-gassing from a recent repaint accumulates rather than dispersing — a particular concern in newer, well-insulated homes. Low-VOC products eliminate this risk entirely.

Specific Health Considerations

Safe for:

• Asthma sufferers
• Pregnant women
• Infants and children
• Chemically sensitive individuals
• Elderly
• Pets

Our experience: We've painted many homes with occupants remaining throughout. No issues with low-VOC products. Parents of young children and families with asthma sufferers frequently comment that the absence of paint smell was a genuine surprise — they expected to need to vacate and didn't have to.

Environmental Impact

Carbon Footprint

Resene's NZ manufacturing:

• Shorter transport distances than imported paints
• Local raw materials where possible
• Modern efficient manufacturing

Compared to importing paint from Asia or Europe, Resene's local production represents a significant carbon saving per litre — particularly relevant when whole-house projects require 60–100 litres of product.

Waste Reduction

PaintWise Programme:

• New Zealand's paint recycling scheme
• Drop unused paint at Resene ColorShops or transfer stations
• Paint reprocessed or disposed of safely
• Keeps paint out of landfills

How to participate:

1. Take unused paint to ColorShop
2. Unopened tins may be refunded/exchanged
3. Opened paint accepted for recycling (no cost)

The Wellington Resene ColorShop on Tory Street accepts PaintWise returns during regular trading hours. If you have leftover paint from a previous project sitting in the garage — particularly older solvent-based products — PaintWise is the responsible disposal option. Never pour paint down a drain or into garden soil.

Waterborne vs Solvent-Based

Resene's waterborne formulations:

• Water as carrier instead of solvents
• Lower VOCs inherently
• Easier cleanup (water vs thinners)
• Safer for applicators and occupants

Most Resene products are waterborne — a significant environmental advantage. Solvent-based products still exist for specific applications (some floor coatings, high-build primers), but for the vast majority of interior and exterior residential work, waterborne systems deliver equivalent or better results with far less environmental impact.

Resene Eco Decorator Programme

What It Means

Resene certifies painters who:

• Use Environmental Choice products
• Follow sustainable practices
• Maintain high standards
• Commit to eco-friendly approaches

We are certified — one of few Wellington painters with this credential. Certification requires not just using the right products, but demonstrating knowledge of eco-friendly preparation, application, and waste management practices — and being assessed on it.

Benefits to You

1. Expert product knowledge — We understand which eco products suit which applications
2. Application expertise — Low-VOC products need proper technique
3. Waste minimization — We calculate quantities accurately, minimise leftover paint
4. Recycling — We return unused materials through PaintWise
5. Sustainable practices — Proper preparation reduces need for frequent repainting

Wellington-Specific Considerations

Mould Prevention

Wellington's humidity creates mould risk — particularly in older villa stock in Newtown, Mount Victoria, and Berhampore, where ventilation can be limited. Resene's eco products include:

• Mould-resistant formulations (Kitchen & Bathroom range)
• No toxic biocides needed
• Breathable finishes

The mould resistance in Resene's Kitchen & Bathroom product comes from the film-forming properties of the coating itself, not added biocides — which is both safer for occupants and more environmentally sound. Biocide-free mould resistance is a genuine technical achievement and one reason these products carry Environmental Choice certification.

Coastal Conditions

Salt spray and wind demand durable products. Resene's eco exterior paints withstand Wellington conditions without compromising environmental credentials. The Lumbersider and Sonyx 101 ranges are our standard specification for Wellington exteriors precisely because they're formulated for the kind of weather punishment Wellington dishes out.

Healthy Homes Standards

New rental property standards require:

• Adequate ventilation
• Mould prevention
• Healthy indoor environment

Low-VOC paints contribute to compliance. For Wellington landlords navigating Healthy Homes requirements, specifying Environmental Choice certified coatings and maintaining product documentation demonstrates a commitment to occupant health that supports compliance discussions with Tenancy Services.

Beyond Paint: Sustainable Practices

Our Eco Approach

• Accurate estimation (minimal waste)
• Proper surface preparation (maximizes lifespan)
• Quality application (reduces failures)
• PaintWise participation
• Efficient scheduling (reduces travel emissions)
• Digital documentation (less paper)

Sustainable painting extends beyond low-VOC products. The most sustainable paint job is one that doesn't need redoing for 10–12 years instead of 5–6. Proper surface preparation, correct product selection, and quality application are the three factors that determine paint longevity — and they're the same factors that determine overall environmental efficiency.

Frequently Asked Questions

Do low-VOC paints actually perform as well as traditional products?

Yes — in most applications, indistinguishably so. Resene has been refining its low-VOC formulations for over 20 years. The SpaceCote range delivers the same coverage, adhesion, and washability as any comparable product at higher VOC levels. The only area where some trade-offs remain is very high-build specialist primers and certain industrial floor coatings, which are rarely relevant for residential projects.

Do eco paints cost more?

Negligible difference. Most Resene products are low-VOC as standard — you're not paying a premium for an alternative. The Environmental Choice certified products sit across the same price points as the broader range. There's no additional cost to choosing sustainably with Resene.

How quickly can we use the room after painting?

With low-VOC products, rooms are ready for normal use after drying — typically 2–4 hours between coats and overnight after the final coat. You don't need the extended airing-out period that older high-VOC products required. In practice, most Wellington homes can be repainted room by room with occupants moving back in each evening.

Is low-VOC paint safe for a baby's nursery?

Yes. Resene's low-VOC and zero-VOC products are specifically appropriate for nurseries and children's bedrooms. The Environmental Choice certification covers human health impacts explicitly. We regularly paint nurseries using SpaceCote products and have had zero adverse reports from families. The key is allowing the standard drying time — overnight at minimum — before the room is reoccupied.
