What is a Low/Zero-VOC paint?
A low-VOC paint is a type of paint that contains low levels of Volatile Organic Compounds (VOCs).
VOCs are chemicals that easily evaporate into the air as paint dries. Traditional paints release a lot of them—that’s what causes the strong paint smell and can lead to headaches, dizziness, eye irritation, or long-term health issues.
What makes low-VOC paint different?
- Fewer toxic fumes during and after painting
- Better indoor air quality
- Safer for homes, schools, hospitals, and enclosed spaces
- More eco-friendly
How low is “low”?
It depends on regulations, but typically:
- Low-VOC: under ~50 g/L (grams per liter)
- Zero-VOC: under ~5 g/L (and may still have trace VOCs from pigments)
So, Why Low/Zero VOC paints can be a problem when wrapping walls?
- Low-VOC paint can cause vinyl adhesive to fail because its chemistry and curing behavior are different from traditional paints. Low-VOC paints often dry fast but cure slowly.
Vinyl adhesives need a stable, fully cured surface to bond. If the paint is still outgassing or soft beneath the surface, the adhesive can’t properly “grab” and may lift, reason why Low/Zero VOC paints require longer curing times than regular VOC paints. - 2. To replace solvents, low-VOC paints use more surfactants (soap-like additives that help pigments spread). These can rise to the surface as the paint cures, creating a microscopic slick layer that repels adhesive, similar to trying to stick tape to soap residue.
- Additives designed to repel stains also repel glue
Many modern low-VOC paints include:
- stain blockers
- scrub-resistant additives
- anti-blocking agents
- Hydrophobic agents
Great for walls. Terrible for vinyl adhesion.
