The use of appropriate conservation techniques is critical to the preservation of buildings. Part 1 of this 3-part Digest gives advice on how to apply safe, effective, appropriate and enduring conservation techniques to stonework. It outlines how to identify the stone and associated mortars, and how to diagnose the causes of soiling and deterioration. It advocates avoidance of cleaning to optimise the life of masonry but outlines its use where appropriate. The other parts will cover conservation of terracotta, brickwork, renders, plasters and stucco. The companion Digest 502 explains the principles of the conservation of masonry in historic buildings.
