Inform Guide: Lime and Cement in Traditional Mortars

Overview

This INFORM guide focuses on two commonly used mortar types in Scotland: lime mortars and cement mortars, and the impact that the use of these materials has on stone-built structures. An overview of the physical properties of both mortar types is given, as well as an indication of their technical suitability for use with traditional stone masonry. Selecting a suitable mortar for repair works is important for the conservation of traditional buildings and for preventing masonry decay associated with the use of incompatible materials.
