"It is critical as a homeowner, with massive amounts of conservation work to do, to be able to do as much as possible myself. These courses empower attendees to have the confidence to do these repairs." - 2021 course delegate

 

This introductory, 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 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), a conservation builder/plasterer (Michal Wolf) and a heritage consultant (Rob Workman).

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.

Lunch and refreshments are provided. Accommodation is not included.

"The course content was revelatory. I knew a little about hot lime mortars and had a small amount of practical experience but the information supplied answered all my questions. It pretty much turned my lime world upside down and as a consequence I have changed my working practise" - 2021 course delegate

 

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

Lunch and refreshments are provided. Accommodation is not included.
