Eco-friendly, low-VOC paint in Geneva

VOCs: what the acronym really means

VOCs, or volatile organic compounds, are substances that evaporate from the paint film at room temperature, especially during drying. They are what cause the “fresh paint smell” and spread into the air of the room.

Two simple ideas help to make sense of it:

• Water-based paints generally emit fewer VOCs than the old solvent-based paints (oil-based). Most current interior paints are water-based.
• “Low-emission” does not mean “zero”: there is always a residual share of emissions, which decreases over time. This is why ventilation and drying matter as much as the product itself.

The word “eco-friendly” sometimes covers other aspects (raw materials, recyclability of the packaging). For indoor air quality, the decisive criterion remains the VOC emission level.

Reading labels and emission classes

Several markers help to compare products objectively, without relying on a marketing promise printed on the tin. The point is to tell a sales argument apart from measured, verifiable data.

Indicator	What it tells you
VOC content (g/l)	Amount of VOCs in the product, governed by the European regulation adopted in Switzerland
Emission class (A+ to C)	Emissions measured in the air after application: A+ = very low emissions
Recognised eco-labels	Independent environmental and health specifications
Technical data sheet / safety data sheet	Detailed manufacturer data, to be requested if in doubt

A good habit: favour products showing a high emission class (A+) and keep the technical data sheet. Renovhome SA can indicate the nature of the products chosen during the quote visit.

Why favour low-emission paint: children’s rooms and sensitive people

Choosing a low-emission paint makes full sense in certain situations where indoor air deserves particular attention.

• Children’s and babies’ rooms — young children spend a lot of time in their room; limiting emissions is a sensible precaution.
• Sensitive people — asthma, an allergic predisposition, respiratory sensitivity or simply discomfort with smells.
• Poorly ventilated or continuously occupied rooms — home offices, bedrooms without a large opening.
• A home reoccupied soon after the work — moving in shortly afterwards, re-letting.

In these cases, a low-emission product, combined with good ventilation, reduces exposure during the most sensitive phase, the one immediately following application. The olfactory comfort of a living room also matters for adults.

Ventilation and drying: the right steps after application

The product is not everything: the way you ventilate and respect drying directly influences air quality after the work. A few practical pointers, valid even with a low-emission paint.

• Ventilate during and after application — opening the windows and keeping a through-draught helps the residual VOCs to disperse.
• Respect drying between coats — the time between two coats depends on the product, the temperature and the humidity of the room; follow the indications on the technical data sheet.
• Wait before putting things back — a residual smell may linger for a while; ventilate thoroughly before putting furniture and textiles back in place.
• In the case of water damage — the surface must first dry out before any repainting, the necessary time being checked with a moisture meter.

These simple steps speed up the return to healthy air and take nothing away from the final result.

How Renovhome SA approaches interior painting in Geneva

Renovhome SA applies low-VOC paints and factors this dimension in from the quote visit, without turning a health topic into an overblown selling point. The method stays the same everywhere across the canton, from the older flats of Eaux-Vives to the modernist estates of Le Lignon, Onex or Meyrin.

In practical terms, during an on-site visit:

• Room-by-room recommendation — we flag the rooms where low-emission paint is particularly relevant, such as a child’s room.
• Consistent choice of finish — the emission level is combined with the finish suited to the use (see the painting glossary).
• Preparation and protection — the same protocol for protecting the premises and preparing the surfaces.
• Detailed quote — each item is described room by room, after a visit and with no commitment.
