Rapid decay of the physical heritage is a significant issue and urgently requires remediation. Microbial generated or catalyzed decay amounts have substantially increased in the industrial age primarily via inorganic and organic air contamination. They are most quick in rock art, pre-historical and historical mural painting, and antique marble structures and sculptures. In the structure of several interdisciplinary research study tasks and networks, bio receptivity in addition to bio susceptibility of therapeutic agents for the protection of physical culture heritage was studied or reviewed. Masonry biocides used in the control of organic developments are seldom explicitly formulated for structure materials, and there is now an expanding problem for their total impacts on the rock. A unique method was developed that used dried biocide residues after touching with various sandstone types. A typical method, power dispersive XRD, was then used to examine the possibility of the biocides causing the dissolution of stone components. Of the biocides utilized in the analysis, a quaternary ammonium compound with no natural borate had a minor result in the dissolution of rock components. A biocide containing dichlorophenol showed up to trigger some dissolution of silicate minerals, the impact likely to be related to its high pH. The third biocide, an alkylamine, produced the dissolution of Al, Si, K, and Fe. Clay minerals seemed one of the most susceptible to the alkylamine biocide’s effect. The mode of action is associated with the development of clay-amine developments, resulting in clay dispersal. Rock minerals in the biologically decayed sandstone were much less vulnerable to the activity of the biocides. It could be associated with the existence of various microbial items included in the stone. However, the action of masonry biocides on decayed stone requires even more research to illuminate a specific mechanistic activity. This research has revealed the analysis of biocide treatment sandstone problem of application, issue, and environmental hazards.
