Beautiful and Healthy Natural Paints
Even something as apparently innocuous as the paint for the walls of the house can be an environmentally friendly gesture if, instead of using synthetic paints, we choose the biological and natural paints. In fact, the traditional synthetic varnishes are dangerous for the environment, but they can also cause serious harm to our health. This is a good reason to use natural paints, which can perfectly meet the various painting needs and tastes.
Generally, organic paints are have a very low environmental impact since they are made with natural ingredients that are safe for those who produce to those who use them and for those who live in the house. They are sold in a wide range of colours and shades are not at all inferior to their chemical "sisters".
What are the real benefits of choosing natural paints instead of the chemical ones?
- they have the same or a better result than those of synthetic origin;
- they are odourless, so the premises must not be ventilated after their preparation;
- they do not contain harmful and toxic volatile substances;
- they enhance the breathability of the treated material;
- in some cases they can absorb fine dust.
How is it possible to recognize the natural paints on the market? It is advisable to read the labels to make sure you are buying the right product and investing in quality and health protection. Most of times, they are marked by the European Ecolabel.
Among the most important brands of manufacturers of natural paints there are:

- the Italian SOLAS;
- DURGA, that uses renewable vegetable raw materials.
Some Notions On Natural Paints
Paintings are generally composed of: pigments, binders, mineral fillers and adjuvants.
In the case of natural paints all the ingredients must obviously be found in nature. Here's a round-up.
- Pigments: natural powders, colourant plants, cobalt blue, aged lime, white zinc, iron oxides, titanates.
- Binders or glues: fresh egg white and egg yolk, fresh milk, casein, starch, beeswax, oils.
- Minerals: amorphous and crystalline calcium carbonates, kaolin, mica, talc, marble, alabaster, sand.
- Adjuvants: Borax, calcium borates, alum, essential oils, plant extracts, soaps, vinegar, alcohol, methylcellulose, propolis.
In general, natural paints are washable, breathable, and long-lasting.
Defects of synthetic paints
Synthetic pigments veer with the action of ultraviolet and infrared rays unlike the natural ones. Then change colour over time. Often, they are not breathable, a feature that is required for the health of a home and its inhabitants. They always contain some chemical solvents which are toxic to humans. FInally, after painting a room, toxic particles remain in suspension for 3 or 4 weeks and the toxicity remains in the house even for years.
Therefore, if you want to restyle your home, use natural paints.
Besides that you can buy on the market, it is possible to produce absolutely natural paints at home with a few simple ingredients.
For example, here are two common recipes of natural paint based on milk and clay.
