Lime mortars for traditional brickwork

Monday 25 September 2017


The course

The day will consist of introductory talks with slides covering:

  • The variety of limes and their uses, the current issues.
  • Suitability of purpose, no lime is a bad lime if properly used.
  • Non-hydraulic and hydraulic limes, traditional and modern preparations.
  • The decay of buildings and why historic buildings need lime.

The talks will be followed by practical demonstrations on how to make a decent lime mortar properly, so that a tradesman can use it.

The tutor

Dr Gerard Lynch is an internationally acknowledged leader in the field of brickwork and mortars and their historical conservation. His practical and technical skills in the use of traditional methods and materials are outstanding. He is author of Gauged Brickwork: A Technical Handbook, Brickwork: History, Technology  and The History of Gauged Brickwork.

It has long been Gerard’s belief that current understanding and practices do not fully reflect the traditional methods of lime and mortar making and he has stood out against fashionable trends in conservation, with well-researched evidence to support this.

He has a hands-on philosophy and a pragmatic view of how and why craftsmen went about their tasks in the past. Understanding non-hydraulic and hydraulic lime mortars is not rocket science, it is practical, sensible, achievable pragmatism backed up by centuries of evidence to support the use of lime mortars for all aspects of building works.

This day school will show that the physical evidence for Gerard’s opinions abound all around us, including in the Museum’s buildings.


£115 per person, to include tuition, teas and coffees and a light lunch.
