Another new course for our lovely building contractors\u2026 Have you been asked to make and use hot mixed lime mortars for conservation projects? Not yet? Well, you soon will be\u2026 there has been a growing interest in the truly traditional way of producing mortars \u2013 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.<\/span><\/p>\n

Calce Viva (Italian for \u2018alive lime\u2019 aka quicklime).<\/span><\/p>\n

This one day workshop aims to provide an introductory guide to the preparation and use of\u2019 hot mixed\u2019 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 \u2018cold mortars\u2019. More and more clients and specifiers are asking building contractors to make and use \u2018hot mixed\u2019 mortars on their repair jobs, so get ahead of the game and brush up your knowledge and skills with us.<\/span>
\n\u2018Hot mixed\u2019 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 \u2018cold\u2019 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 \u2018hot mixed\u2019 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.<\/span><\/p>\n

By the end of the course, attendees will be able to recognise traditionally made \u2018hot mixed\u2019 mortars in historic structures and buildings and be able to develop the skills to produce and successfully cure \u2018hot mixed\u2019 mortars in relation to authenticity, performance, exposure, season, substrate and nature of the masonry repairs required.<\/span><\/p>\n

Course suitability<\/u><\/p>\n

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 \u2018hot mixed\u2019 mortars successfully.<\/span><\/p>\n
