One of the most important criterion for the long-term future of the building is that the pointing mortar must be both softer and more porous than the masonry. Softer and porous mortar can be achieved using traditional mixes held together by the carbonation of lime putty. This is the only way of ensuring that the wetting and drying cycles are dealt with by mortar and not the actual fabric of the building. Additionally, the relative softness and porosity of the mortar will also reduce potential problems that is incorporated with the growth of salt crystals within the pore structure of the stone or brick. It will also enable salts to be drawn to the surface of the masonry without damaging the stone or brick.
