Evaluation of treatment products for the front door of the church of Santiago, Guadix
Abstract
In a previous article the materials and the state of conservation of the Front Door of the church have been characterized, with the aim of determining the causes and the alteration mechanisms that are present in it. In the present work the behaviour of several treatments, water repellents and/or consolidants, is evaluated to determine their effectiveness and their answer to the weathering factors. With this object, several characteristics of the stone, before and after the application of treatments, have been determined, as well as the weathering resistance that has been measured subjecting the samples to alteration tests that reproduce the observed weathering mechanisms, salt crystallization and freezing-thawing.
