Evaluation of the penetration of restoration materials in stone. A new method

We have used the measurements of the water-stone contact angle on the surface of sections of biocalcarenite samples to evaluate the penetration of organic and silico-organic restoration products in this rock. The method has been found to be effective and precise, allowing us to distinguish the depth of the zone with water-repellent characteristics from that with merely a consolidating effect. Se utilizan las medidas del ángulo de contacto agua-piedra sobre la superficie de secciones de probetas de biocalcarenita, para evaluar la penetrabilidad de productos de restauración orgánicos y silicoorgánicos en esta roca. El método se revela como eficaz y preciso, permitiendo discriminar la profundidad de la zona con características hidrófugas de aquélla exclusivamente consolidada.
