Can Classicbond EPDM be joined?


Classicbond EPDM Membranes can be easily joined using either the 3" splice tape or some 6" covertape. Primer must be used when joining two sheets as the self adhesive tapes will only adhere to a primed surface . Please see our video installation guide to see how this is done using the 3" seam tape.

Can RESITRIX Sheets be joined?

Yes! The membrane can be joined and sealed by using a hot air gun with a flat nozzle and seam roller to creat a heat weld. It is easy to tell if a good weld has been formed as there will be a bleed on the welded edge. You can watch our installaton video to see how this is done.
