Abstract: (1746 Views)
The reinforcement and hydrophobicity enhancement of historical construction materials, particularly the surfaces of historical stones, are among the most sensitive and challenging interventions in cultural heritage conservation. These interventions require precise analysis and comprehensive research to minimize potential side effects. Such actions are especially essential when stone artifacts exposed to open environments suffer from severe degradation and erosion or exhibit significant surface changes, potentially leading to loss of aesthetic and structural integrity. Without timely intervention, erosive factors may penetrate deeper layers of the artifact, posing a risk of complete collapse. In this study, the performance of three industrial silane/siloxane-based coatings Wacker 290, Wacker 3003, and Long Life was evaluated in the coating process of stone materials. The physical, mechanical, and especially hydrophobic properties of these materials on stone surfaces were analyzed and compared. Results indicated that all three materials exhibited moisture-repellent properties. However, Long Life and Wacker 290 demonstrated superior performance due to their better bonding with stone surfaces. These findings provide effective guidance for selecting suitable materials in conservation projects of historical artifacts, preventing the premature deterioration of these invaluable heritages.
