I had to make a repair to the rubber on the roof which involved removing the front termination bar. I have one tube of dicor self leveling sealant and about 40 feet of 2" wide Eternabond tape. I have no butyl tape and no way to get any before the next rainfall. Is there a reason I couldn't/shouldn't use the eternabond to tape the metal edge of the front to the rubber roof, then put the termination bar over that?

Normally you use 4 inch Eternabond over the whole thing between the roof and the cap. For a quick fix using what you have, you can put the "termination bar" back on and put your 2 inch Eternabond along it with 1 inch overlap, so with 40 feet and 8 ft to do, you could do two 8 ft, with one overlap making 3 inches. Or even three and get 4 inches.It is hard to do all 8 ft with one length --it gets twisted up in the wind and turns into a nightmare, so shorter lengths overlapping end to end is more practical. Your 40 ft leaves enough for overlapping the end to end and for the lengths.You might not need the Dicor at all. Purists put Dicor along the edges of the Eternabond, but how long is this for, before you get some 4 inch and do it over top of this one?

You indicate trying to be economical in roof repair/maintenance...have 2 inch tape but not 4 inch tape. Not wise IMO.

It is hard to do all 8 ft with one length --it gets twisted up in the wind and turns into a nightmaresorry to askbut how is 8ft across, hard to tape downi've never found EB to get twisty, you must be putting it down during a windstorm/Galei've run full length front to back over 30ft using 4" , just smooth it down as i unroll it, my only hassle is keeping a straight line/edge and not wiggling back & forthor is that what you meant ?

That seems like there would be more opportunity for leaks that way. Are you saying put the tape over the termination bar?

No, Mr Wiz, I am such a spaz I can't pull the clear plastic underlay off and lay out the Eternabond like you are supposed to as you go along and keep it straight. Not enough hands! So I would get the clear part off all the way from shorter lengths, but even the shorter lengths would get in the breeze. With any luck the OP is not such a spaz as I am, and it will go better. :)---OP, You can overlap Eternabond and it will stick. You still have to sort of "work it in" to activate the glue. There are rollers for that, but I just do it by hand. Probably not so good, but it seems to work Ok.I am not clear on the "termination bar" but if it is the moulding piece across the roof at the cap, usually that is Dicored down original, so a repair would be to cover the whole thing with wide Eternabond. (at least that is one way).So if that is all off now, I don't see any advantage in putting it down over tape and taping over it above that. Why not just put it down without the Butyl under it and the Dicor above it, and just go straight to the Eternabond over it all?
