What does low VOC mean?

VOC = Volatile Organic Compounds. Paints < 30 g/l are considered low VOC and are safer for interiors.

Low-VOC Paints

The smell of a freshly painted room once meant "cleanliness" - in reality it's chemical air pollution. We spend 90% of our time indoors - air quality matters. What does VOC mean, which certifications count and what should you watch out for?

What Are VOCs & Paint Categories

Infographic: VOC - Volatile Organic Compounds, evaporation from paint

VOC = Volatile Organic Compounds. Chemical substances with a boiling point ≤ 250°C that evaporate at room temperature:

Where Are They?

In the solvents & additives of the paint. As it dries they're released into the air → headaches, eye/throat irritation, long-term respiratory damage.

The industry classifies paints by VOC content:

Infographic: 3 categories - Conventional, Low VOC, Zero VOC

Conventional (Within Limits)

Complies with legislation (< 30 g/l for matte interior). Noticeable smell during application.

Low VOC

Significantly lower than the legal limit - far fewer fumes.

Zero VOC

< 5 g/l. Practically odourless. Room can be used immediately (nurseries, bedrooms, clinics).

Certifications & the Tinting Trap

"Eco-friendly" on the tin isn't enough - look for official marks:

Certification	What It Guarantees	Ideal For
EU Ecolabel	VOC < 10-15 g/l, no heavy metals/carcinogens + high opacity	General interior use
French A+	Room air emissions at 28 days - highest grade	Building certification
Indoor Air Comfort Gold	Combines strictest EU criteria (AgBB, A+, BREEAM, LEED)	Best-in-class IAQ
EN 71-3	Toy safety - no migration of heavy metals	Children's rooms, nursery furniture

⚠️ The Tinting Trap

VOC levels on the tin refer to the white base. Dark colorants can add VOCs! Make sure the store uses Zero VOC Colorants.

Technical Corner: Legislation & Emissions

For engineers, architects & specifiers:

Infographic: Decopaint 2004/42/EC, Content vs Emissions, TVOC

Directive 2004/42/EC

EU regulatory core. 12 sub-categories (A/a-A/l) with maximum VOC content (g/l) "ready for use." Category A/a (matte interior) = 30 g/l.

Content vs Emissions

VOC Content (g/l) = composition in the tin. VOC Emissions (µg/m³) = release rate at 3 & 28 days (ISO 16000). Low content ≠ low emissions!

LEED / BREEAM / WELL

2004/42/EC compliance isn't enough - they require Emissions Evaluation (Indoor Air Comfort Gold, EMICODE EC1+). TVOC ≤ 300 µg/m³ at 28 days.

Conclusion

Low-VOC paints protect indoor air quality without compromising durability. Look for certifications (EU Ecolabel, A+, Indoor Air Comfort Gold), ask about the colorants and - if targeting building certification - request an emissions certificate.
