Abstract This study represents a synthesis of the worldwide built structures which lasted across centuries due to the durability obtained by mixing some natural materials enriched with natural polymers. This work aims to identify the natural polymers influence in obtaining mortar plasters during the buildings evolution techniques. The research sets itself to bring into the front line the forgotten or abandoned solutions. The organic plant supplements and the animal derivates which can be identified inside mortars are usually found at the local plan of the construction. The main additions are: milk products, casein, organic fat, rice, plants saps and different herbs.
