ALSAN RS Roof waterproofing system - the professional's choice The ALSAN RS roof waterproofing system is used on the flat roofs of such constructions as industrial units and high-rise buildings, and especially for the refurbishment of such roofs. It is also suitable for the rapid and reliable waterproofing of specific areas, i.e. all upstands associated with ventilators, roof lights and gullies. The main product is the ALSAN RS 230 resin, a highly flexible and UV-stable PMMA resin formulation. The water- proofing is perfectly matched to the requirements on site, since ALSAN listens to and implements customer demands. The application method is straightforward: The substrate must be dry and sound. It is prepared and, if necessary, pre-treated as indicated on the substrate table. For instance, substrates such as asphalt, concrete or screed are primed, while bitumen sheets are not. The fleece-embedding layer (approx. 2,0 kg/m 2 ) consists of PMMA resin and is generously applied with a lambswool roller. The fleece is incorporated in the liquid resin and any air inclusions removed. The fleece acts as a layer thickness control and lends the system its mechanical properties. The fleece is then saturated with more PMMA resin (approx. 1,5 kg/m 2 ), which is applied wet in wet. If necessary, a top coat can be applied after a short interval to increase the chemical and mechanical resistance. A final sealer makes the surface easier to clean and provides a range of attractive design options.
