It would be worse in terms of stone durability an increase of the stone surface roughness than a decrease or flattening, because the first case derives to the increasing of the specific surface of the stone, which generally turns into more surface area to be exposed, a higher particle retention (Vazquez Calvo et al 2012) [14] and therefore an acceleration of its decay.
