Traditional mortars are eminently workable, effectively porous, economic in use and appropriately durable. Used in buildings for thousands of years, these materials are ideal for repair and conservation work. Unlike cement or modern hydraulic lime, their routine use would make a significant contribution in the struggle against climate change. However, despite the 1975 'lime revival' there remains a deficit in research into the most-used traditional mortars. This book seeks to redress the balance.

Drawing upon historic literature, material science and industry case studies, topics covered include:

  • A historical overview of traditional mortars
  • Slaking and mixing hot mixed lime mortars
  • The essentials of pozzolans, aggregates and lime tempering
  • Plasters, lime washes and sheltercoats
  • The revival of interest in the use of like-for-like and compatible mortars

" Most professionals involved with the repair of fabric, and particularly members of the Building Limes Forum, will know that this book has been coming. The rest of us have probably heard about it. Well-respected educator and stonemason Nigel Copsey has been at work on this magnum opus for many years. This book is very well produced. This is a book that I believe all Members of our Association MUST read, mark and learn if involved in any way in the repair and maintenance of masonry or cob buildings.

" A thoroughly well-researched document, presenting many references with very good practical advice and will serve as a very useful manual for those looking to understand or use mortars made this way. A valuable contribution to the contemporary lime movement's perpetual debate on all things lime. "
