Lime mortar plastering

Lime mortar is primarily used in the conservation of buildings originally built using lime mortar, but may be used as an alternative to ordinary cement. It is made principally of lime, water and an aggregate such as sand. With the introduction of ordinary cement during the 19th century, the use of lime mortar in new constructions gradually declined, largely due to portland’s ease of use, quick setting, and compressive strength. However the soft, porous properties of lime mortar provide certain advantages when working with softer building materials such as natural stone and terracotta. For this reason, while ordinary cement continues to be commonly used in brick and concrete construction, in the repair of older, stone-built structures and the restoration of historical buildings the use of OPC has largely been discredited
