Inform Guide: Restoration Mortars for Masonry Repairs

This INFORM provides information on the use of proprietary restoration mortars for repair of stone masonry. It identifies the types of products available for carrying out such repairs; the scenarios in which their use might be appropriate; the practical considerations for their use; and the associated visual implications. The use of restoration mortars is neither a long term or ‘like-for-like’ repair approach for traditional buildings, but situations can arise where it provides an acceptable solution for minor masonry repairs.
