During renovations of St Andrews Church on the Terrace in the Spring of 2008 we installed a rare 3 layer torchon roofing system to the Portico Entry roof. Previously it had Mastic Asphalt on the concrete structure which had bubbled and blown all over.
We melted and removed the asphalt bubbles and the main contractor had the plastering contractor screed over the old asphalt with a 20mm thick polymer modified plaster.
The plaster was allowed to cure then we primed it with Nurabond No10 adhesive and torched down Nuraply3PV vent sheet to the flat area and Nuraply 3P Basesheet to the sloping parts.
Both areas were then followed by a layer of 3P Sanded 3mm and a final third layer of Nuraply 3PM 4mm thick Mineral finish.
The job was finished off with Coloursteel wall flashings around the perimeter fitted into a polyurethane sealant filled saw cut in the plaster. After we left the job the plasterers applied a final coloured coat of plaster onto the walls down to our metal flashing.
