We used it to replicate early cast concrete ornament and decorative cornice work on Mills Mansion (McKim Mead White) in Staatsburg, NY. Fabricated by Mike McLeod and Co., the stuff has weathered very well. The original modillions, individually cast by Italian craftspersons, were partially supported by wires strapped to mild steel pipe set into the modillion walls. When the pipe corroded, the mods. fell on passersby. We painted the stuff - the glass fibres will break down under UV load.
