Let Versico simplify your next EPDM or TPO installation with Weathered Membrane Cleaner. Weathered Membrane Cleaner is used to clean both new and in service VersiGard&Reg; EPDM black and white membrane and VersiWeld&Reg; 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, QA Seam Tape and flashing. Do not use Weathered Membrane Cleaner on PVC membranes-instead use PVC Membrane Cleaner.
