RIBA South Conservation: water staining and efflorescence in historic masonry

Jamie Fairchild, Director of Restorative Techniques Limited, is our guest speaker for the October RIBA South Conservation Group talk. Join us for an enlightening exploration of the challenges faced by historic structures and the innovative solutions that have been developed to combat their deterioration.

Few historic buildings have not suffered from defective roofs, rising damp, or leaking pipes. Apart from the physical damage to the affected masonry, there is usually streaking and efflorescence, or the blistering of paint decoration. This presentation will describe and explain these changes and offer options to lessen or remove them.
