Take your lime plastering skills to the next level with this practical introduction to ornamental lime plastering, including running a cornice in-situ and forming external and internal mitres.  

This two-day practical course is taught by three Master Plasterers at the National Trust’s stunning Heritage and Rural Skills Centre.

Our expert tutors will show you how to make a running mould and a silicone mould, cast and fix enrichments, and run fibrous plasterwork formed ‘on the bench’.

This course is kindly supported by the Worshipful Company of Plaisterers which means we can offer some places at a subsidised rate of £150.
