Historic Masonry Restoration and Repair
Half Day $275
This is a half-day hands-on workshop (which runs from approximately 8 am to 12:00 pm) held at The Craftwork Training Center in Telford, PA. The workshop is for those who want to learn to use Natural Hydraulic Lime (NHL) mortars to repoint vintage brick and stone masonry. NHL mortars contain NO Portland Cement. Portland Cement is not required in the NHL mortars that we teach with and which we suggest to use when repointing most vintage brick and stone buildings that were originally built with lime mortar. Portland Cement is known to be harmful for repairing brick and stone masonry buildings when the masonry building was originally built with lime mortar. This is because of the brittleness and non-breathing, dense nature of Portland Cement which can trap moisture in the bedding mortar of a wall leading to potential swelling during freeze/thaw cycles and worse. Portland cement mortar also negatively reacts with salts which accelerate the breakdown of a well-intended replacement mortar that is a "high lime content" mortar which only contains a small amount of Portland Cement. These "high lime content mortars are frequently specified with the intent to make a mortar which is more accommodating to movement and breathability but unfortunately they also undergo pre-mature decay in their service life from these reactions. There are two price points for this workshop. Option #1 for Professionals is $1000 per participant which includes a credit of $1,000 toward future purchases of our materials when the material is redeemed within one year from the date of the program. This in essence makes the workshop free for historic masonry restoration companies. Option #2 is $200 per participant for just the workshop. A $100 non-refundable deposit per person is required two weeks in advance of coming to the program. The hands-on workshop will cover tips and tricks in the proper mixing, placing, texturing, tooling, curing and cleaning when performing repointing work with LimeWorks.us Ecologic™ Mortar which is based on Natural Hydraulic Lime containing No Portland Cement. Ecologic™ Mortar is simply a prepared blend of Natural Hydraulic Lime binder/aggregates and pigments to which you just add water, mix and go to work. Ecologic™ Mortars come in 12 stock colors and the workshop shows how everyone from a DIY to a professional can produce hundreds of new shades by blending them in various degrees. This is helpful for the professional who is called to install mock-up examples for Historic Restoration Architects to review and shows the mason how to tweak the mix to represent various nuances in the original mortar for the architect’s acceptance of the mix design before the whole project were to begin. We will show how to add such inclusions as marble dust, mica, slag flecks, oyster shells, and regional sands and then how to simulate a weathered surface of an historic mortar joint in order to create a close to indistinguishable match to original historic mortar. By practicing these techniques in patch pointing and full re-pointing work the intended outcome for what is being taught is a foremost learning to develop an attention to detail. Honing the development of attention to detail is the beginning of what would ready a participant and a crew to carry out "museum-quality" restoration work. At this workshop we also explain our services for properly sending a sample to our laboratory for custom color simulations. If any professional masonry company or organization gathers a group of at least 10 participants we will schedule a program at the group's chosen location anywhere in the USA if the full $1000 per participant price is paid for the 10 or more participants. The participating company will be credited to receive the full $10,000 value of actual LimeWorks.us products if they are obtained within one year of the workshop. This in essence makes the workshop free for historic masonry restoration companies.
Architects, Engineers and their firms are invited to observe this workshop and hear supporting information on what to consider when writing a specification for a proper historic repointing project and what to look for if work is or is not being carried out in a good and workmanlike manner. The cost is $60 per participant. 4 Learning Units can be self-reported for on-going education.

This is a four-day hands-on workshop (which is repeatable in succession if the work is not completed) is held at a historic site. The historic site will actually have substantial repair work accomplished during the program time. The intent is to instill an attitude toward historic masonry conservation that is respectful of irreplaceable historic fabric and understand how to sympathetically work a repair into and adjacent to the original material. A global mindset toward understanding the building in its environment, the building’s importance, how it was constructed, by who and why it came into existence along with why it and any significant architectural details should be kept in conservation is part of the philosophy discussed during this program. These are questions that every practitioner of historic building repair work should ask before engaging in a repair intervention. The workshop shows end-users how to better decipher the original mortars or plasters used to build the vintage building and spot the inappropriate forms of intervention used to create well-meaning but un-complementary repair work accomplished over the subsequent years from the time of original construction to the current state it is in. The inappropriate repairs may be deemed "inappropriate" based on non-compatible use of materials or simply not be sympathetic to what was the architect and builder's original intent. The intent of the workshop is to get the fix back on track with what is interpreted as the original intended design details. This workshop reviews performing a visual mortar analysis and one using an acid-digestion process of the targeted mortar(s) which is planned to be simulated for reinstallation by repointing. Visual observation of the original sand color and sizes found in the original mortar is reviewed when the mortar sample is sifted and separated into various gradations. Methods to properly prepare the historic masonry walls by cutting and squaring back original mortar joints will be addressed in repointing workshops. To ready walls for repointing, techniques for cutting without irreversibly damaging historic masonry units will be practiced, along with cleaning the masonry in preparation if needed. Placement of new materials and especially the incorporation of reconstituted historic elements in the effort of their reinstallation will be carried out whenever possible. This program is specifically a repointing or a re-plastering workshop but may cover other details. Various details may be listed on the Tentative Calendar Schedule because the historic site or building types may be different. Cost is $750 per participant for four days. A $100 non-refundable deposit per person is required two weeks in advance of coming to the program. The Field School Program is a hands on workshop intended for the participant who wants to get into this line of work professionally or wants to get a better well-rounded understanding of many of the details behind a historic masonry restoration campaign and business. Four Day Sets are $750. This program can be continued upon in four day sets in consecutive weeks based on the participants desire to keep working with us. Work is always on an actual historic building and its interrelated building details. Note to Non-Profit Sites: Underfunded historic sites can use this opportunity to host this workshop. By doing this they can leverage the value of the participants help in reducing the overall cost to complete the needed repair work that can be accomplished during the program because the participants will be guided by our Technical Install Team. Please inquire with your budget and allow us to design a workshop around your budget and preservation needs utilizing this available labor. Architects, Engineers and their firms are invited to observe this workshop on the first day of the four-day workshop and hear supporting information on what to consider when writing a specification for a proper historic brick and stone repointing or plaster refurbishment and what to look for if work is or is not being carried out in a good and workmanlike manner. The cost is $100 per participant. 6 Learning Units can be self-reported for on-going education. Lunch is also included for all who attend workshops that are more than ½ day.
