I've used zero-VOC paints a couple times, and honestly, they're not completely odorless. Definitely less harsh than regular paint, but there's still a faint smell—especially noticeable in smaller spaces. Ventilation helps, but don't expect zero smell just because the label says zero-VOC. I'd say it's less of a gimmick, more like marketing stretching the truth a bit...
You're spot-on about the odor. I've recommended zero-VOC paints to clients aiming for greener homes, and while they're definitely a step up from traditional paints, there's always been that subtle smell lingering around. Especially noticeable in smaller rooms, like bathrooms or closets—just as you mentioned. Ventilation does help a lot, but it's good to keep expectations realistic.
Still, props to you for making the effort! Every little choice counts when it comes to building healthier spaces, and even if zero-VOC isn't 100% odor-free, it's still reducing harmful chemicals significantly. Marketing can be tricky, so it's great you're paying attention and sharing your experience.
Had a similar experience when we redid our guest bath last year. Went zero-VOC thinking we'd dodge the smell completely, but nope...still lingered for days. Definitely better than traditional paint, but yeah, ventilation's key—open windows and fans saved us.
"Went zero-VOC thinking we'd dodge the smell completely, but nope...still lingered for days."
Interesting you mention that—I've noticed similar things on a few of our recent projects. A couple points I've picked up along the way:
- Zero-VOC doesn't always mean zero odor. Some paints labeled "zero-VOC" still have other additives or solvents that can cause lingering smells. Learned this the hard way after a client complained about odors in their newly built home, despite us using supposedly eco-friendly paint.
- Ventilation definitely helps, as you mentioned. But I've also found that humidity and temperature play a big role. Higher humidity seems to trap odors longer, so running a dehumidifier alongside fans and open windows can speed things up.
- Another thing worth checking is primer choice. Sometimes the primer underneath isn't zero-VOC, and it can contribute significantly to lingering smells even if your topcoat is clean.
- Also, curious if anyone's tried activated charcoal bags or air purifiers during painting? Had a colleague swear by charcoal bags placed around freshly painted rooms—said it noticeably cut down on odors within hours. Haven't personally tested it yet, but might be worth experimenting with next time.
Overall, I think it's great we're all trying to build greener and healthier spaces—but clearly there's still some trial and error involved in getting it right...
Good points about humidity—I hadn't really thought about that. Tried charcoal bags once, seemed to help a bit, but wasn't a miracle fix. Wonder if certain paint brands have fewer additives causing odors...? Might be worth looking into.
