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.
