The Archbishop's House:  Weathered render and lime paint on front column at the portal. The render was resurfaced with KEIM Universalputz Render, a lime-rich historic blend render mortar. The surfaces were recoated with KEIM Soldalit sol-silicate mineral coating system designed for previously-painted and rendered surfaces.
The Archbishop's House:  Decorative concrete exhibited cracks at the deck edges.
The Archbishop's House:  Failing concrete edges from inappropriate concrete repairs. The broken mortar patches were removed revealing deep voids. Deep voids were filled with coarse-grained KEIM Restauro Base restoration mortar with a final lift of Restauro Top fine-grained restoration mortar in a matched color. Soft carving is possible for 12 hours.
The Archbishop's House:  Weathered rendered surfaces of the apse. Surface voids were parged with KEIM Universalputz Standard Render followed with two more 1/8 inch layers of Universalputz Render with KEIM Glass Fiber Mesh embedded in-between the layers, and finished to match the historic surface texture.
The Archbishop's House:  A close view of the apse wall detailing the depth of crumbly render. Water intrusion has eroded the surface leaving the core friable.
The Archbishop's House:  The base layer of KEIM Universalputz Standard Render applied with the KEIM Glass Fiber Mesh embedded into the surface. The Mesh is overlapped four inches at edges. This assembly is allowed to cure overnight before the top Render layer is applied and decoratively finished and ready for the sol-silicate Soldalit mineral finish.
The Archbishop's House:  The Soldalit sol-silicate mineral coating is applied to mock up the interior side of the corner column at the southeast corner of the front portico.

About This Project

The Archbishop's House is one of seven magnificent structures located around the Queen's Park Savannah. Built in 1903-1904, it was the palatial residence for Patrick Vincent Flood, the fifth Archbishop of Port of Spain. The restoration included stone repairs, historic stucco repair and replacement, paint stripping, and repainting with a highly vapor permeable sol-silicate mineral coating system.

Regional Info The climate is tropical. There are two seasons annually: the dry season for the first five months of the year, and the rainy season in the remaining seven of the year. Winds are predominantly from the northeast and are dominated by the northeast trade winds. Unlike most of the other Caribbean islands, both Trinidad and Tobago have frequently escaped the wrath of major devastating hurricanes. In the Northern Range, the climate is often different in contrast to the sweltering heat of the plains below. With constant cloud and mist cover, and heavy rains in the mountains, the temperature is much cooler. Record temperatures for Trinidad and Tobago are 102 °F for the high in Port of Spain, and a low of 54 °F.
