An Introduction to Lime in Building
11 November 2021

This one-day course led by expert tutors is ideal for anyone new to using lime in building or keen to expand their basic understanding. Through a combination of illustrated talks and practical demonstrations, it will explain the different forms of lime available and look at a range of uses, from pointing to plastering and lime washing.    

The course will be delivered by a specifier (Marianne Suhr), conservation builder (Rob Workman) and experienced lime plasterer (Michal Wolf). The small group setting will allow plenty of opportunity for questions and discussion.   

This beginner / intermediate course will appeal to builders already working with lime and looking to extend their knowledge, or who want to begin using lime. It is also suitable for owners of period houses or other old buildings looking to develop their understanding of traditional materials, and specifiers wishing to develop or enhance their understanding of lime and its many applications.   

The SPAB is an IHBC recognised CPD provider and attendance certificates for CPD are available on request. Spaces are limited to allow for small group learning.

Tutors:

Marianne Suhr - historic buildings surveyor
Marianne is a chartered building surveyor, writer and broadcaster specialising in the repair of historic buildings. After completing a scholarship with the SPAB, she spent seven years in architectural practice. Marianne gave up her desk job to concentrate on practical building projects, whilst co- presenting three series of BBC2’s ‘Restoration’ programme. She has repaired and adapted four houses of her own, and used the experience gained to set up ‘The Old House Consultancy’. Marianne lectures extensively on building repair and runs courses for builders, homeowners and professionals. 

Michal Wolf - plasterer and conservator in lime
Michal is the founder of All Things Lime, a small but dynamic company which helps owners of traditional buildings and national charities to look after their historic buildings. Michal believes in a positive and sensible approach towards caring for historic buildings, and is also interested in traditional methods of working and keeping the craft alive by researching and using different lime plasters (such as chalk lime and hot lime). 

Rob Workman - heritage consultant
Rob has over 15 years specialist experience in the heritage construction sector - project managing conservation building works utilising traditional craft skills and appropriate materials and, more recently, as a conservation officer for South Oxfordshire and Vale White Horse District Councils. Rob now runs his own historic building and heritage planning consultancy, Lime&Listed, in South Oxfordshire.

 

 

Hot Limes in Building
12 November 2021

This one-day course led by an expert tutor is ideal for anyone with basic knowledge of lime who wants to explore the use of hot mixes in more detail. Through a combination of illustrated talks, video and demonstrations, it will provide a practical insight into hot limes and their use.

After many years producing lime mortars by first slaking putty, then mixing with sand, it is now widely accepted that mortars were traditionally mixed ‘hot’. This means slaking the sand alongside the quicklime in a single operation.  Course tutor Nigel Copsey has spent years researching the methods used for making mortars, and has many years of site based experience using hot lime mortars in the repair of historic buildings.   

The day will be a mixture of illustrated talks and demonstrations, covering slaking methods, different mixing methods, application and aftercare. Nigel will also explain the essential properties of hot lime mortars and explore the reasons for their superior performance in terms of shrinkage, durability and frost resistance.  

This intermediate course is especially relevant for builders already working with lime and looking to extend their knowledge and use of hot mixes, and to specifiers wishing to develop or enhance their understanding of hot lime and its applications. It will also appeal to anyone carrying out practical building projects who is familiar with lime but interested in learning more about hot mixes. It provides up to date information on our understanding of traditional mortars, as well as detailed practical instruction and is therefore essential for anyone working in the field. It assumes a little background knowledge of lime, and anyone completely new to the subject is recommended to attend the 'Introduction to Lime in Building’ course, taking place the day before. There will be ample opportunity to ask questions and discuss issues during both courses.     

The SPAB is an IHBC recognised CPD provider and attendance certificates for CPD are available on request.
