First of all, let's make clear what an eco-paint actually is and what makes it different compared to the conventional ones. In order to make a paint well-spreadable, manufacturers use both chemical and natural solvents. They ensure easy application and even coverage, but a downside, is that they pollute the indoor climate, but also negatively influence the environment - moreover, even the natural solvents (terpenes) can be carcinogenic.
On the contrary, some natural paints are beneficial for the environment and may serve you a good purpose, if you suffer from allergies. Eco-friendly paint (also eco-paint, natural paint, bio-paint or organic paint) is a generic term for all paints made from natural raw materials, which are usually of plant or mineral origin.
There are a large variety of natural paints of plant or mineral origin. However, that does not mean that all natural paints are always purely organic and eco- friendly since there are no legal regulations that would control that. For example, manufacturers sometimes add formaldehyde chemical preservatives to their natural paints to make them more durable. Another thing is that natural paints may sometimes contain substances that are considered to be safe for the human body, but their manufacture may harm the environment. Therefore, people who care about the environment and allergy sufferers, in particular, should carefully check the ingredients of natural paints and avoid terpenes in particular.

Some eco-paints indeed require up to six coats to receive full coverage. And generally, natural paints lack levelling agents and fillers, that’s why it’s sometimes not that easy to apply the paint. Dripping paints with low opacity cause nothing but trouble. Depending on the surface, you should therefore apply a primer to make the paint adhere better. If you want to achieve good results without painting three times, you should rely on quality natural paints. This will not only save you time but also money. High-quality eco paints contain enough pigments which allow them to have great opacity.
