Restoring the Broadway Promenade exterior, a story of collaboration

Located in Sarasota, Florida, the 10-year-old Broadway Promenade Condominium was in need of repair.  The stucco was cracked, unbounded and inadequately cured during construction, resulting in a high alkaline stucco.  As a result, the exterior paint exhibited severe alkaline burn, became mottled in color and had begun to delaminate and peel despite several attempts to repaint areas.

A thin veneer overlay system comprised of Sto RFP, fiber reinforcement mesh and Stolit Lotusan finish was used to resurface areas that required substantial stucco repair. For areas that only needed recoating, StoColor...
