As we do some winter housekeeping, we are reminded of some of our favorite past projects. This portion of a frieze (circa 1885) from a terracotta façade in Fulton Market was brought to us in rough shape several years ago. We thoroughly cleaned old mortar and dirt from the pieces and reassembled them using epoxy gel and stainless threaded rods. The cracks were patched and the upper corner was rebuilt using Jahn M100. This repair mortar was custom matched to the original terracotta clay color. The patches were stippled and sculpted to mimic the relief of the original frieze and Keim Soldalit potassium silicate was applied over the entire piece to match the original glaze color. The finalized piece was reinstalled using stainless steel eye bolts and custom tinted Type O mortar. This project was both a fun and challenging one for the HFS restoration team! ...
