Henry Frerk Sons Workshop


Our intensive hands-on two-day Jahn Restoration Training Workshops introduce traditional methods of masonry repair using Jahn Restoration Mortars. This includes the repair of limestone, sandstone, terra cotta and brick. The objective of these workshops is to demonstrate materials and techniques to achieve long lasting results. Our classes welcome masons, contractors, craftspeople, specifiers, and other preservation professionals. Architects can receive AIA/CEU credits upon request.

Successful completion of the Jahn Restoration Workshop is necessary to purchase Jahn Repair Mortars M70, M100, M120, and M160. $450.00 for two-day session.
