Hot Mixed Lime Mortars Course

24 April & 18 May 2018
Venue: Charlestown Workshops, Fife

Another new course for our lovely building contractors… Have you been asked to make and use hot mixed lime mortars for conservation projects? Not yet? Well, you soon will be… there has been a growing interest in the truly traditional way of producing mortars – by mixing quicklime and sand together in one operation (and possibly with other materials and additions) and critically when it is appropriate to use them post production. Come and brush up your knowledge and skills and able to sell more services in the building conservation industry.

Calce Viva (Italian for ‘alive lime’ aka quicklime).

This one day workshop aims to provide an introductory guide to the preparation and use of’ hot mixed’ lime mortars, that is, mortars prepared by slaking quicklime, sand and natural hydraulic lime binders (and possibly other additives like tallow or pozzolans) to more closely mimic the appearance and technical performance of conservation mortars and in some cases offer advantages in use and technical performance over more conventional ‘cold mortars’. More and more clients and specifiers are asking building contractors to make and use ‘hot mixed’ mortars on their repair jobs, so get ahead of the game and brush up your knowledge and skills with us.
‘Hot mixed’ mortars have a long history of use in the UK, with evidence visible throughout the nation on traditional buildings and structures. Since the lime revival of the mid 1990s however, the preparation and use of conservation mortars has been largely dominated by lime putty bound mortars or ‘cold’ mortars based on natural hydraulic limes (NHLs). Whilst all these mortar types have their place, a renewed interest in the production of what are perceived to be more authentic mortar preparations using quicklime and sand has been growing and this workshop aims to take the building contractor through the process of making and using ‘hot mixed’ mortars safely, constituents to be used, preparation of mortars, correct mixing equipment and critically at which point these mortars should be used for particular applications.

By the end of the course, attendees will be able to recognise traditionally made ‘hot mixed’ mortars in historic structures and buildings and be able to develop the skills to produce and successfully cure ‘hot mixed’ mortars in relation to authenticity, performance, exposure, season, substrate and nature of the masonry repairs required.

Course suitability

This course is aimed at building contractors (including stonemasons, bricklayers, lime workers and labourers) involved in historic building repair, reconstruction and the consolidation of historic structures and give you the confidence to make and use ‘hot mixed’ mortars successfully.

Learning outcomes:

  • Ability to recognise traditionally made ‘hot mixed’ mortars in historic buildings and structures;
  • Ability to make and use ‘hot mixed’ mortars successfully;
  • Understand at which point, post production of ‘hot mixed’ mortars, these mortars should be used.

 Course programme through a blend of theory and practical sessions

  • Health and safety briefing;
  • Historic preparation and use of lime (and other) based mortars;
  • Understanding the range and production methods of lime binders available in the UK today;
  • Understanding other mortar constituents including sands and aggregates, pozzolans and other additives such as animal fats and milk products;
  • Why specify ‘hot mixed’ mortars? Including issues of authenticity, performance, workability and challenges thereof;
  • Causes of failure – including slow slaking, slow carbonation, wet and exposed locations, unpredictable materials and avoiding failures;
  • Making and using hot mixed lime mortars for repairs to traditional buildings– factors to consider, mix proportions, appropriate mixing equipment, when to use ‘hot mixed’ mortars post production and Building Standards;
  • Perceived barriers to specification – including Health and Safety for safe storage of materials, mixing regimes and safety in use.
