Air Bubbles in EPDM Rubber Membrane
Air Bubbles in EPDM Rubber Membrane
(OP)
Could anyone enlighten me with what may have caused this rubber membrane to get these air bubbles in it. The EPDM was used in an attempt to seal up a leak on a metal roof that had a galvalume finish. I am not sure what type of adhesive was was used to adhere it to the metal panel. Is the EPDM delaminating?

There are specific techniques required during installation to minimize the amount of air entrapment. If the membrane were transparent these techniques would be obvious.
