It seems that the primer is a thin adhesive. why is the tape (additional layer of rubber and two extra layers of adhesive) needed? Everyone does it this way, but i dont understand why. the cost difference is very large, so there must be a reason why adhesive alone does not work for EPDM membranes.

So its not necessary to use a cleaning product before priming?
Is there anyway of installing in one piece when the osb box is already fixed in place?
