SCHEDULED DEMONSTRATIONS:

Cathedral Stone Products
Terra Cotta Restoration
This hands-on demonstration showcases our complete terra cotta restoration system, guiding attendees through every step of patching and casting TC pieces with our specialized mortar. Presented in a live, cooking-show format, participants will get hands-on experience patching terra cotta with our mortar, while seeing finished and in-progress pieces side by side as we walk through applying our Potassium Silicate paint and Terra Cotta glaze to complete the restoration process.

Darwen Terracotta
Historic Terra Cotta Restoration
This session follows the complete lifecycle of a historic terra cotta restoration project, from initial 3D scanning of a damaged or missing unit through to a finished, kiln-fired replacement. Attendees will see how field survey data is translated into accurate shop drawings, how those drawings inform hand-built models and plaster moulds, and how the moulding, casting, and firing process produces a unit that matches the original in profile, texture, and colour. The demonstration is designed to give architects, engineers and contractors a clear, practical understanding of what’s involved in specifying and sourcing like-for-like terra cotta replacements on Landmarked and historic buildings.

York Flashings / Heckmann Building Broducts
Wall Flashings and Transition Membranes
This presentation will cover a detailed explanation of the challenges and solutions facing through-wall flashings and transition membranes, provide a thorough description of the characteristics of several types of membranes, emphasize the importance of compatibility, and explain proper installation techniques.

Vestacast
Fabrication of GFRC Units
Hands on fabrication of GFRC units and understanding the uses of GFRC as replacement for Terra Cotta and natural stone facade elements

TCC Materials
Terra Cotta Composite Repair
This session will review best practices for composite repair of Terra Cotta. TCC Materials will review proper substrate preparation and installation.

Boston Valley Terra Cotta
Laser Scanning for Terra Cotta Replacement
This course demonstrates how high-resolution laser scanning is used to capture existing architectural terra cotta units that require replacement and create accurate digital models for restoration projects. Participants will follow the workflow from scanning deteriorated or damaged units through digital modeling and learn how the resulting data supports estimating, drafting, and the production of precisely matched replacement units.

Prosoco
Helical Anchors in Terra Cotta
This hands-on demonstration introduces participants to the installation and performance of helical anchors in terra cotta masonry. Attendees will learn proper installation techniques and observe field testing methods used to evaluate in-situ anchor performance, accounting for variations in substrate condition. The session will demonstrate how installation practices and performance testing can be used to develop reliable, project-specific repair solutions for terra cotta restoration.

Edison Coatings
Architectural Terra Cotta: The Art and Science of Longevity
Architectural terra cotta has demonstrated exceptional long-term performance on building facades, remaining a defining feature of many historic structures generations after installation. This hands-on course explores the material properties, manufacturing processes, and performance characteristics that have contributed to terra cotta’s durability and continued use in facade restoration projects. Through case studies, material demonstrations, performance testing data, a virtual manufacturing plant tour, and a hands-on unit pressing activity, participants will examine how terra cotta is produced, how historic units are documented and replicated, and how performance testing and lifecycle evidence demonstrate the material’s long-term durability in facade applications. Participants will also explore how modern restoration projects continue the legacy of this durable and versatile architectural material. Participants will gain a practical understanding of how proven field performance, lifecycle considerations, and preservation objectives inform restoration, replacement, and material selection decisions.

Gladding McBean
Terra Cotta Repair and Preservation
Terra cotta repair and preservation is a multistep process, requiring installation of the proper materials in the correct sequence to achieve long term performance and match color to the original aesthetic of the structure. Terra cotta is a composite material, using a fired clay bisque as the main body and a ceramic glaze on the exposed surfaces. The clay bisque and the ceramic glaze have different properties and the best long term performance is achieved by matching the properties of the repair materials to the original terra cotta properties.

Registration Closes on Friday, September 25th at 5:00pm

Although our ICRI and NWiR teams will do our best to accommodate last minute requests to register for our upcoming 2026 Demo Day, our team of volunteers will be carefully managing AIA CEU tracking with in-person sign-in sheets and ensuring organized groups for this full-day learning opportunity and we cannot confirm that venue space or CEUs will be available for those who have not signed up by Friday, September 25th. 

We appreciate your understanding and thank you for your interest in our ICRI & NWiR 2026 Terra Cotta Demo Day.
