Due to the possibility that the public can join and interact with these large-format works, an important flow of face-to-face visits is created around them, as well as a massive virtual reproduction of them, generated by the spectators themselves when sharing the images. photographs in their social networks, messages and other media.

Regarding the production conditions,

To carry out these works in interior or exterior spaces, walls and floors, a period of on-site work is necessary, which may vary depending on the degree of complexity and size of the works. In some cases, three in another six days, they must always be studied a priori, because they are optical illusions that require adjusting to the project and the architecture of each particular context.

Water-based colors are used and the degree of durability of each work will depend on the type of paint used. Many are ephemeral works, they will fade with the passing of days and the rains, although, if required, they can be kept in good condition for longer on floors and, preferably, on walls. The style of each work always obeys the artist's personal signature. Eduardo Relero has been entrusted with numerous campaigns by Amnesty International, Greenpeace, Firefox, the Red Cross, Complutense University, Microsoft and other national and international institutions.

Murals with chemical capacity to improve the environment

There is the possibility of using paints capable of absorbing and mineralizing greenhouse gases known as carbon dioxide (CO2) and nitrogen oxides (NOx) in a harmless matter for the environment and human health.
It has been possible using mineral compounds created and patented by Spanish laboratories
This has been recently done by Eduardo Relero in the center of Helsinki, a huge mural with the ability to absorb gases that are harmful to the environment
