SPAB – Historic Flint Masonry Repair
18 April - 09:00 - 19 April - 16:45
£350Learn the essentials of flint working techniques and traditional flint wall repair on this Humble Heritage course.
Join us at Hatfield House for this hands-on two-day course. You will learn the essentials of flint working techniques and traditional flint wall repair from specialist Lynn Mathias, one of the few remaining practitioners of this endangered craft.
Through a combination of live demonstrations and hands-on sessions, you will learn how to assess, prepare and repair traditional flint walls. You will be working on a 17th century garden wall in the grounds of Hatfield House, giving you plenty of opportunities to try out your new skills on real historic masonry, under the expert supervision of one of the country’s leading flint specialists.
Although this is an introductory course, you should come away from this workshop with the confidence to tackle your own flint masonry repairs.
Flint has been used as a building material since Roman times, prized for its durability and beauty, as well as its abundance and availability. Masonry flint knapping is now a critically endangered craft, but Lynn hopes that courses like this will help to pass on knowledge and skills vital to keep the craft alive so it can one day be removed from the endangered craft list.
