This CPD session is aimed at experienced conservation professionals and practitioners. David Wiggins will examine the response of traditional solid masonry walls to moisture, probing the issue of the ‘breathability’ of old buildings. Sacrificial weathering will be unpacked as a process, and modern mortars critically evaluated for compatibility against hot-mixed lime mortars. Practical specification guidance will be given on lime mortar for exposed conditions.
