Abstract
This paper aims to show part of the research carried out in the investigation of consolidation materials in Cova Remígia (Castelló, Spain), a rock shelter with Levantine rock art. Research was aimed to determine the suitability of the application of various calcium hydroxide-based (Ca (OH)2) nanoparticulated consolidants to open-air calcareous surfaces in order to evaluate their potential use in the conservation of rock art. In order to understand the behaviour of these consolidants and their interaction with the rock, a comparative study was carried out comprising Nanorestore® and four products from the CaLoSiL® range. These are colloidal solutions based on calcium hydroxide Ca (OH)2 dispersed in different types of alcohols and in different concentrations, applied on stone supports with carbonic matrix. These are products designed for heritage conservation, specifically for treatments on stone supports, mortars, wall painting, etc. Previously, when testing the products, the chemical-mineralogical characterization of the support was carried out and the nanostructural features of the consolidants were analysed individually in order to know their physical crystallization behaviour and its possible benefits. At the same time, the evolutionary follow-up of these treatments took place, through the support of colorimetric, thermo-hygrometric studies and SEM-EDX analysis. This previous scientific knowledge on consolidating materials is part of the protocol for the preventive conservation of the rock shelter, since this methodology sets the guidelines advisable to use and follow by conservators-restorers, when facing problems of consolidation, fixation and decohesion of this type of stone support.
