More and more homes across Spain are switching to low-VOC ecological paints, not just following a trend but responding to the direct impact on family health and indoor air quality. However, with labels promising to be "ecological" and certifications that look technical, it is not always clear what makes a paint truly respectful of the environment and the people living in the painted space.
What are VOCs and why they matter in your home
Volatile organic compounds (VOCs) are chemical substances that evaporate easily at room temperature and are released into the air during and after paint application. Conventional paints can contain high levels of these compounds, which are responsible for headaches, eye irritation, dizziness, and respiratory problems, especially in children, elderly people, or those with allergies.
In Spain, European legislation sets maximum limits for these compounds: up to 30 grams per litre for water-based interior paints carrying the Ecolabel mark. Paints labelled "No VOC" must contain less than 5 grams per litre. The largest VOC release occurs during the first three days after application, which is why the intense smell of fresh paint that lingers in newly painted rooms is so common.
Key differences between ecological and natural paints
It is important not to confuse "ecological paint" with "natural paint". Ecological paints typically comply with standards such as the European Ecolabel and are manufactured with acrylic bases containing reduced amounts of VOCs. These are the paints readily available in conventional paint shops in cities such as Madrid, Barcelona, Valencia, or Sevilla, and they represent a clear improvement over traditional paints.
Natural paints, on the other hand, are formulated without synthetic chemicals, using vegetable oils (mainly linseed), natural resins, casein, citrus derivatives, and silicates for exterior use. Their pigments contain no heavy metals and come from earths, metal oxides, and other mineral or plant-based products. These paints allow walls to breathe, do not create an impermeable layer over plaster or cement, and are suitable even for people with high chemical sensitivity. That said, they are not usually found in conventional stores and their distribution is more specialised.
Certifications to look for: Ecolabel and other labels
To identify a truly ecological paint, the most reliable approach is to check its certifications. The European Ecolabel is a voluntary mark that guarantees the product meets strict criteria for pollution reduction, low energy consumption, and absence of hazardous substances (such as formaldehyde, heavy metals, or phthalates). You will recognise this label by its logo in the form of a flower with a euro symbol in the centre.
Other relevant certifications available in Spain include Natureplus, which certifies that at least 85% of the composition comes from renewable raw materials, and EMICODE, managed by the German GEV association, which classifies VOC emissions into three categories (with EC1 being the lowest emissions). These labels are a much more solid guarantee than generic claims of "low odour" or "ecological" without official backing.
Brands and distributors available in Spain
The Spanish market offers a mix of natural and ecological paints manufactured locally or imported. Among natural paint brands, AURO (distributed by Alen and Calche in Madrid), Naturclay (based in Santiago de Compostela, specialising in clay and lime coatings), Com-Cal (Barcelona-based manufacturer of bio-building materials based on lime), and Keim (silicate mineral paints distributed by Ecopaint Ibérica) stand out. German brands such as PNZ, Kreidezeit, and Livos are also available, distributed by specialised companies.
As for Ecolabel-certified ecological paints from conventional manufacturers, several Spanish brands offer dedicated ranges: Bruguer (with its Ecosense line), Isaval (Duin Blanco and Espacios Collection), Blatem (Pintura Ecoluz and Eco Green), Pinturas Lepanto, Montó (Magnum and Zero lines), Titanlux (Candance), and others such as Graphenstone or Tkrom. These options are more accessible in paint shops and large DIY stores throughout Spain, from Andalucía to the Basque Country, across Catalonia, the Valencian Community, and Galicia.
When to use ecological paint: spaces and situations
Ecological and low-VOC paints are especially recommended in children's bedrooms, baby rooms, homes where elderly people or those with respiratory problems live, and generally in any space where people spend a lot of time. They are also very practical when you need a room to be ready to use the same day, since the low emission levels allow you to sleep or work without waiting days for the smell to clear.
In cities such as Málaga, Bilbao, Zaragoza, Murcia, Alicante, or Granada, where homes may have humidity or ventilation issues, reducing indoor VOCs becomes particularly important. Natural paints also offer additional benefits in this regard, as they allow walls to breathe and better regulate indoor humidity.
One final practical tip: if you are requesting quotes to paint your home, you can mention in your request that you prefer certified ecological paints. On our platform, we always ask for photos and videos of surfaces before finalising any quote, which allows the professional to assess the real condition of your walls and recommend the most suitable type of paint, both in terms of performance and its impact on health and the environment. Remember that payment is handled in two parts: 50% at the start (to reserve the date and purchase materials) and 50% at the end, once the work has been verified.
