Rough concrete must be faired up before commencing application. Existing membrane shall be clean. All blisters and defects in the old membrane must be cut out and repaired as required to provide a good sound substrate to which the new membrane system may be applied. Timber substrates may require a primer coat of Adhesive A901 cut back with Solvent 10 by 50% and allowed to dry prior to applying the Rollbase sheet product. Application Planning the installation of the membrane is important to ensure joints occur in suitable locations. Rollbase is generally laid to allow side laps of 50 mm with the end abutted and not overlapped. When the membrane has been installed, a strip of smooth membrane such as Argo / Fidia / Modo/P at least 15 cm wide, should be bonded over the traversal joints. Fully or part bonding The Rollbase shall be unrolled and set in to the exact position in which it is to be attached; it shall be folded back sideways to expose half of the underside. Refer to Adhesive A901 SDS specifically regarding the Flash Point and Flammability. Apply a coat of Adhesive A901 to the exposed surface (either fully covered or spot bonded dependant on the requirement), work the membrane back into position avoiding wrinkles or entraping air bubbles. Repeat the process with the rest of the sheet. Upon completion broom out any air to maximise adhesion. A minimum drying period of 2 hours with good air-flow is required to dry the adhesive – ENSURE THIS IS DONE BEFORE USING ANY HEAT SOURCE IN THE AREA AND ENSURE ALL ADHESIVE A901 CONTAINERS ARE REMOVED FROM THE AREA. After installation of the Rollbase the side laps shall be heat fused together to provide a homogenous joint. The bonding of the laps and overstripping of the traversal joint must not be carried out until the adhesive has been allowed to fully dry for a minimum of 2 hours. Nailing on wood Mechanically fixing Rollbase may be mechanically fixed over concrete, timber or insulation panels. The membrane shall be unrolled and set in to the exact position in which it is to be attached. The membrane shall be fixed with washers and the appropriate fixings. Generally the fixings are placed at the edge of the Rollbase with the adjacent sheet layed over the fixing to encapsulate the fixing. The fixing spacing will be dependant on the Engineers requirements however generally the spacing for the fixings is 1 m apart through the main area and 50 cm around the perimeter. Rollbase is generally installed to the horizontal surface only with al detail and up-stands detailed with a layer of plane Index membrane such as Argo / Fidia /Modo/P. Index® Rollbase
