Air toxins from paint: what the reporting has found

A note on this article. The version of this post that ran on our old site reproduced a 2010 Daily Mail feature by Angela Epstein in full. We’ve replaced it with our own summary and a link to the original, because the original is the journalist’s work, not ours. If you want the full piece, read it at the source.

Most people redecorate without a second thought about what they’re breathing while they do it. The health reporting on this is not new, and it is not fringe — it has been covered in the mainstream press for well over a decade.

The short version

Ordinary decorating products are chemistry. Conventional paints contain solvents and volatile organic compounds that evaporate as the paint dries and continue off-gassing long afterwards. Paint strippers, varnishes and two-pack products can contain considerably harsher agents again. And the jobs around painting — sanding old coatings, stripping wallpaper, cutting back and replastering — put dust into the air that has its own risks, particularly in older properties.

The people most exposed aren’t homeowners doing one room a year. They’re professionals doing it every working day, in enclosed spaces, often without adequate ventilation.

What the coverage consistently flags

  • Solvents and VOCs in conventional paint, released during application and drying, and associated in the research literature with respiratory irritation, headaches and longer-term effects with sustained exposure.
  • Isocyanates, found in some two-pack and specialist finishes, a well-documented cause of occupational asthma in the trades.
  • Dust from preparation work — sanding, stripping and replastering — including the risk of disturbing older materials in period properties.
  • Ventilation as the single biggest controllable factor. Most guidance comes back to the same point: the enclosed room is what makes the exposure serious.

Why we work in lime

This is the reason our finishes are what they are. Limewash and lime plaster are high-calcium lime, water, marble dust and mineral pigment. There are no synthetic binders and no solvents, so there is nothing to off-gas — not on day one, and not in year five. Lime is also naturally alkaline, which means it resists mold and mildew without added biocides.

We’re not claiming lime is a medical intervention. We’re saying that if a wall finish can be beautiful and not put solvents into the air of a bedroom, that’s the one worth specifying. That’s the whole basis of our Zero VOC Home Program.

What to do about it

The Zero VOC Home Program Every wall and ceiling moved off paint, measured before and after, from $85 a month. Interior limewash Zero VOC, breathable, and it filters formaldehyde back out of the room. The EPA study The measurements behind the claim that indoor air is the more polluted air.
