%X 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. En un art赤culo anterior se han caracterizado los materiales y el estado de conservaci車n de la Portada de la iglesia, con objeto de determinar las causas y los mecanismos de alteraci車n que aparecen en la misma. En el presente trabajo se eval迆a el comportamiento de diversos tratamientos, hidr車fugos y/o consolidantes, para determinar su eficacia y su respuesta frente a los factores de alteraci車n. Para ello se han determinado las propiedades h赤dricas y mec芍nicas, y la resistencia a la alteraci車n se ha valorado sometiendo las muestras tratadas a ensayos de alteraci車n que reproducen los mecanismos de deterioro observados, la cristalizaci車n de sales y la heladicidad.
