Abstract: The facades of historic buildings are mostly coated with mortars, usually based on air or
hydraulic lime, or they are left uncoated. As these mortars are the most external elements of
these constructions, they are also the most exposed and the first to undergo degradation
and, therefore, the first to require conservation/replacement. The choice of these
replacement/repair mortars requires very special care. According to the available standards,
the performance of these mortars is evaluated based on laboratory-produced test samples,
with standard specimen dimensions and under standard curing conditions. The behaviour of
the mortar, over time, will be influenced by the characteristics of the substrate and by the
interface that will be created between substrate and mortar. The present study is part of a
broader investigation within the scope of the IF Mortar project, which aims to analyse the
influence of the characteristics of several substrates on the characteristics of different
mortar types. In this paper, results obtained during previous experimental campaigns,
related to the mechanical characteristics of several mortars applied to different substrates,
will be presented.
