THe electric company threw away a bunch of this stuff and i brought home a lot of it, not knowing quite what I would do with it. I think I'll make a floor for a greenhouse and the runway for the r/c airplanes now that I know how to stick it together. Just need to figure how to hold it down when it gets windy.

Is there anyway of installing in one piece when the osb box is already fixed in place?

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?
