This means that while it’s easy to obtain everyday building materials including mortar, they may not be compatible with older buildings and walls as they may set harder than the surrounding stone or brick, which can quickly lead to ‘spalling’; the breaking up the wall if it is prevented from the natural micro movements and necessary breathing, which prevents moisture build up and frost damage.
