As the number of historic buildings continues to increase, so does the demand for masons who have the necessary skill and knowledge critical to the preservation of vintage structures. A skilled and exacting mason can match rebuilt sections of masonry to the original in terms of stone type and size; patterns of jointing and coursing; and mortar color, texture, and profile. Properly done, repointing restores the visual and physical integrity of the masonry. Improperly done, repointing not only detracts from the appearance of the building, but may also cause physical damage and decay to the stone or brick. The ultimate success and performance of the repairs depends upon the proper selection of materials and the quality of the work performed by the masons. This workshop is designed to elevate the level of craftsmanship of participants by introducing the techniques needed to simulate special joint profiles such as ribbon, weathered ridge, beaded, and/or grapevine repointing. Regardless of the type of mortar joint being installed, it is essential that existing joint profiles should be followed where encountered in historic restoration projects. The lecture, demonstrations, and hands-on exercises cover the properties of natural hydraulic lime, tips for selecting and mixing lime mortars, cleaning and filling joints, and consistently tooling and striking specialized mortar joint profiles. Under the guidance of experienced masons from LimeWorks.us, participants will practice the skills on mock-up panels. The additional knowledge and skills may also enable attendees to cultivate a competitive edge in the growing preservation field. The difference is in the details. Prior masonry experience is helpful but not required.

Lithomex is a modified lime-based mortar designed specifically to repair or simulate brick, stone, and terracotta surfaces. Unlike other products that trap moisture in the host stonework, Lithomex is flexible (with a very high modulus of elasticity), porous, and breathable; allowing water vapor to pass through the masonry to the atmosphere for long-lasting repairs. When applied by skilled craftsmen, Lithomex can simulate the color and texture of existing stone and brick while maintaining similar thermal expansion and weathering characteristics of the host material. Lithomex may be worked, tooled, dressed, and finished with traditional masonry tools, trowel edges, sculpting tools, sanding blocks, tungsten carbide abrasive sheet, and scratch floats. This comprehensive workshop addresses the potential causes of brick and stone deterioration and the aesthetic qualities of Lithomex and the properties that ensure its durability and compatibility with the host masonry. Technical knowledge and expertise are reinforced with hands-on demonstrations and extensive practice on mock-up panels. Under the direction of experienced masons from LimeWorks.us, students are guided through the steps to apply Lithomex properly and efficiently to deliver high quality work. Participants will learn how to use Lithomex to form flat, square, plumb, and level surfaces at right angles.

Old windows continue to be important to the mechanics of historic buildings as well as admirable architectural and woodworking achievements. A sash window or hung sash window is made of one or more movable panels or sashes that form a frame to hold panes of glass which are often separated by muntins. To facilitate operation, the weight of the glazed panel is usually balanced by a heavy steel, lead, or cast-iron sash weight or counter-weight concealed within the window frame. The sash weight is connected to the window by a braided cotton sash cord, or a chain, that runs over a pulley at the top of the frame. These older rope-and-pulley style windows are retained by trim that must be removed before the sash can be freed and parts of the window frame must be disassembled to repair a broken sash cord. During the workshop, participants will practice hands-on techniques to carefully remove window trim before lifting out a sash, disassemble parts of the window frame to access and repair broken sash cord, restring a sash, tie off the weights, open a stuck sash, and learn how to give old windows a thermal tune-up by adding weatherstripping. Well maintained historic windows can be airtight, weather resistant, and should last generations without needing replacement parts. Prior woodworking experience is helpful but not required.
