RILEM technical committee Repair Mortars for Historic Masonry (TC 203-RHM) was launched in September 2003 to develop recommendations for the selection of repair mortars for historic (older) masonry. Examples of repair mortars are repointing mortar, bedding mortar, renders and plasters.

In practice many mistakes were being made in choosing repair mortars. There was a clear need for recommendations for selecting repair mortars, based on an explanation of the factors playing a role in regard to the compatibility of the repair mortar with the existing mortar and masonry units, and aspects such as service life and performance.
