This updated, two-day program is designed to provide owners, architects, engineers, contractors and conservators with a detailed, practical understanding of repair systems, mortars and methods for their proper application. Through a combination of presentations, demonstrations and exercises, participants will learn the techniques and approaches needed to properly complete masonry repair and repointing projects. Register for either day, or both days. Each day of the course is preregistered with AIA Continuing Education System for 7 HSW-Sustainable Design LU's.
A. APRIL 9: Terra Cotta, Stone & Historic Concrete Repairs
This workshop begins by illustrating the significance of each of the various materials properties for stone, concrete and masonry repair materials. Through examples and case studies, participants are then provided with an understanding of how to approach material selection.
Approaches to large-scale repair, replication of complex terra cotta glaze finishes, and the special issues revolving around wet terra cotta buildings are detailed. Particular attention is paid to properly sequencing work.
HANDS ON SESSIONS
The workshops include live demonstrations and hands-on exercises, giving participants an opportunity to see and feel the various repair and refinishing systems used in terra cotta and stone repair, and to try their hands at some basic composite repair. Particular emphasis is placed on how to create different textures and profiles, how to blend repairs with adjacent elements, and how to control color variations.
Composite Patching: Deep and Thin-Section Repair Mortars, Casting Mortars
Adhesives and Grouts
Glaze Replacements and Faux Finishes
B. APRIL 10: Historic Mortars & Repointing, Injection Grouting, Natural Cement, Natural Hydraulic Lime, Roman Cement
MATERIALS & PERFORMANCE
This program begins with a review of the basic components, principals and standards applying to both modern and historic masonry mortars and grouts. Included are the basic chemistry of various types of limes and cements, aggregate selection criteria, proportioning guidelines for modern and historic mortars, applicable ASTM Standards, approaches to color control and issues in mortar analysis.
Injection grouting will be illustrated, including case studies and demonstrations. Selection criteria based on compatibility with existing masonry assemblies are discussed.
A new component has been added on Natural Hyfraulic Lime and Roman Cement, two European technologies finding increasing use in North America.
HANDS-ON & LIVE DEMO'S: TOOLS, PREPARATION, MIXING, FINISHING
Live demonstrations and Hands-On exercises will be the focal points of the program, enabling participants to see and better understand the key principles, materials, techniques and issues relating to use of mortars for various types of repointing projects.
Preparation of masonry for repointing will be discussed and various tools and techniques will be demonstrated. Parameters for performing consistent, high quality work will be detailed. Options for designing repointing mixes for both contemporary and historic buildings and structures will be reviewed. Issues of field-mixed vs. prepackaged mortars, proportion vs. performance requirements, and proprietary vs. generic mortars will be discussed.
Quicklime and Hot Mixing, Lime Putty, Lime Hydrate
Natural Hydraulic Lime
Aggregates for Mortar
All materials, course notes, lunches, refreshments and use of a few basic tools. (Those who wish to bring their own tools are welcome to do so.) Certificates of Completion will be provided to all participants.
