Resumen

This paper aims to study the effect of Ca(OH)2 nanoparticles coatings in protecting heritage materials against rain water and acid rain. Ca(OH)2 NPs are a novel solution for consolidating clay-based plasters or adobes in heritage buildings. Ca(OH)2 NPs are transformed into CaCO3 coatings, which are compatible with calcareous earthen materials. However, the performance of Ca(OH)2 NPs coatings in terms of water absorption and resistance to acid environments is scarcely discussed in the literature.
