Intelligent additives and modern technologies for the protection of heritage and historical buildings, as well as their use in earthen architecture, are very important due to their close relationship with geotechnical engineering. These additives have played the role of stabilizers in various earthen buildings from ancient times to the present. Most archaeologists, architects, and anthropologists are involved in the conservation of heritage and historical buildings. They use traditional techniques and materials in various conservation methods. A new revolution has begun for the protection of these types of buildings, utilizing spray techniques for the conservation of historical structures. The size of particles is very important for spray techniques and conservation. Therefore, this research evaluates the existing work of the authors' team on the importance of particle sizes in spray techniques and related methods for future conservation of heritage and historical buildings. Existing and traditional additives were often grouped under one category for all activities. However, recognizing the importance of separating particle sizes into macro, micro, nano, and pico can initiate a new approach to the protection of heritage and historical buildings in various countries.
