This study aims at providing a dataset for selecting the most suitable consolidant for marble, limestone and lime
mortar. Diammonium hydrogen phosphate (DAP), nanolimes (NL), ethyl silicate (ES) and acrylic resin (B72)
were compared. Application was performed by brushing in different amounts to investigate the influence of the
product consumption. Effectiveness, compatibility, durability and sustainability were evaluated. DAP showed
several advantages over the alternative consolidants, in terms of both technical performance and sustainability.
ES exhibited high efficacy but also risks of poor compatibility and durability, together with a high global
warming potential. NL and B72 provided the least promising results
