This pamphlet describes and illustrates the repointing of old stone and brick walling, a common remedial task that is often undertaken unnecessarily, or executed badly. The use of strong cement mortars and of unsuitable joint finishes - particularly the unthinking application of a weather-struck finish in situations where it is not appropriate - are common causes of damage, and all too often repointing is carried out by people with insufficient knowledge or poor technique. Bad repointing can disfigure an old building and, more importantly, harm historic fabric. When the correct materials and techniques are used, however, repointing will look attractive, perform satisfactorily and extend the life of the stones or bricks for many years. Chapters on history, weathering and failure, repointing, preparation of joints, mortar mixes and mixing, application of mortar, references, other advice, and glossary.
