This experimental study assesses the effectiveness of traditional and nano-materials in enhancing the physical and mechanical properties of deteriorated sandstone from Ramesses III Temple, Karnak, Luxor, Egypt. Treatments included Nano Estel (5%), Paraloid B-72 (3%), Paraloid B-72/Nano Estel (3%/5%), and ethyl silicates. Treated samples underwent Scanning Electron Microscopy (SEM) and physical/mechanical testing. Results show that Paraloid B-72/Nano Estel (3%/5%) yielded optimal consolidation, significantly improving sandstone’s physical and mechanical properties.
