Let Carlisle simplify your next EPDM or TPO installation with Weathered Membrane Cleaner. Weathered Membrane Cleaner is used to clean both new and in-service Sure-Seal®, Sure-White® and Sure-Tough® EPDM membranes and Sure-Weld® TPO membrane prior to the seaming process. It helps to loosen and remove dirt and other contaminants from the surface of the EPDM and TPO membranes and leaves a suitable surface for welding or the subsequent application of primer. Weathered Membrane Cleaner should be used when preparing EPDM membranes for application of primer, adhesives, SecurTAPE™, Factory-Applied Tape™ (FAT) and fl ashing. Do not use Weathered Membrane Cleaner on PVC membranes — instead use PVC Membrane Cleaner
