No more intoxicating and polluting the planet: go for green painting! Easy to find, it is hardly more expensive. Composition, rendering and price: zoom for green paint ...
1. How to identify green paints?
Simply thanks to the presence of the logo of a label on the paint bucket. Two eco-labels are issued in France: the NF Environnement mark for the French market and the European Eco-label for the European Union market. To obtain sesame, paints must not contain heavy metals (lead, arsenic, mercury, ...) and their solvent content must be limited.
There are two types of eco-friendly paintings. The most common are acrylic paints. Dilutable with water, their volatile organic compound (VOC) content is minimal or nonexistent. Another option is natural kit paints, to play the little chemist with plant elements and to have a "home made" painting.
2. What criteria to take into account when choosing the painting?
Primordial criterion when choosing: the composition of the painting. Ecological paints are required to inscribe their total composition on the packaging. Check also the logos of toxicity: beyond two, you can be sure that the painting is not environmentally friendly! Acrylic paints are certainly less harmful, they are nonetheless a petrochemical derivative.
Purists and aficionados of the green, opt for 100% natural paints. Top of the top at the green level, they contain no trace of VOC and are made of organic elements. Sunflower oil, hemp, chalk, and natural pigments for color.
Recognized for their perfect respect for the environment, Biofa and Auro are the most famous brands of natural paints. At checkout, good surprise. The price of these is equivalent to that of mid-range synthetic paints. But small organic shops are not the only ones to offer eco-friendly paintings.
Major brands and brands also go green. Dulux Valentine with the range Oxygen, Castorama and its Colors, Ripolin and the Green range. Farrow & Ball has reduced its solvent content by more than 90% on all of its products. Be careful, although they have reduced their VOC content, green paint brands are not safe. They always use toxic binders harmful to health. Before you buy, consider comparing labels.
To note, the effort of the big signs. In the paint department at Castorama and Leroy Merlin, the ecologists are put forward and the choice is considerable. In return, we are close to the final clap for glycero losing ground.
3. Green paint: advantages and disadvantages
Advantages: Without pretole derivatives, eco-friendly paints are both environmentally friendly and healthy. No need to wear any mask, open the windows during or after the application and newborns and pregnant women do not incur any risk. The icing on the cake and decor, the offer of manufacturers is becoming wider. Eco-friendly paints are available in interior or exterior, in matt, glossy and satin, and for any type of support. Thanks to linseed oil, their penetration power is greater and they are not electrostatic.
A natural or acrylic paint does not contain any volatile solvents that evaporate once the paint dries. Unlike binders used in glycero (hydrocarbons and glycol ethers), eco-friendly paints are made from vegetable oils (linseed, castor oil, lavender), kaolin, natural resins, casein ... The dyes, meanwhile , are of mineral or vegetable origin. The risks of intoxication with acrylic paints exist, but are tiny.
Their life and aging is excellent and the risk of flaking very low. Micro porous, they are permeable to water vapor and suffer less the effects of moisture than synthetic paints. Eco-paints are more cost-effective than conventional paints because they cover a larger area than glycero (white spirit paint). Last but not least, they do not smell. A host of benefits for a rendering almost similar to synthetic paints.
Disadvantages: The choice of colors is more limited than for classic paintings. But farbickers like Ressource or Little Green have a wide range of colors. If, despite this, you do not find your happiness, it is possible to "play" with the pigments to obtain the "desired" hue.
At the level of the finish although the result is suitable, it is a little less smooth than with glycero. Another downside, it is not leachable. For the application, it is slightly more complicated than for a classic painting. The support must imperatively contain no trace of glycero. It is still impossible to paint with acrylic on top. Beforehand, it is necessary to sand the support.
On the price side, they are more expensive than the classic first price paints but no more than the good quality synthetic paints. At Dulux Valentine, it takes about € 37 for the 2.5 liters of synthetic paint, matte paint cream, and € 35 for the eco version, Oxygen mat.
