Eternabond on Sidewall Roof Seam

For you Eternabond experts. What size Eternabond did you use for he sidewall roof joint? I'm thinking one inch would do it, but two inches might be a better seal. Thanks in advance.

2" because I wanted to be absolutely sure the the tape overlapped any old sealer that I couldn't get completely off.

I recommend you go up top and measure. It is important to have adequate surface area, on both sides of the seam, covered. I used 3" width to do my seams, others prefer 4" wide tape.

I was contemplating the same thing but am worried about a couple of things. 1) I taped the front and rear cap seams but when I cover my RV the cover blowing in the wind screwed up the eternabond on the corner of the rear cap. It folded the tape over from the pressure of the cover and made a mess. When it gets hot the glue on the tape becomes gooey and the tape will move under pressure.
2) When I recoat my roof with liquid roof over the tape, will it adhere and what happens if the tape moves?
Any ideas out there?

I used 4" on the side wall seams, 6" on the front and rear cap seams, 2" on the antenna penetrations.

I've never had the Eternabond move or release. (I also don't use a cover) Be sure area is clean and firmly roll the tape to activate the adhesive. To really seal the edge of the tape, clean any glue along the edge with mineral spirits then use a bead of the dicor self leveling sealant. I did the area around my skylight 10 years ago that way and it hasn't moved..
Paint or Liquid rubber will cover both the tape and the dicor.
If your Fleetwood has the Alpha rubber roof you will need the primer for the Liquid Rubber...

Hi davismills,
4" wide is what I used. I would use the same width again. It provides significant holding power and a no excuse environment for the repair to work.

Hope somebody can post a picture or two of your work. I am doing my end cap and center line roof seems very soon to cover the 4" original tape with 6" E-bond white.

How do you get the tape under the AC units without removing them?

I am new to RVing and have purchased a 2001 National Tradewinds 7373. I have been re-caulking around all the penetration and need to re-caulk the seams between the end caps and EPDM roof. Is eternal bond the better way to address this issue for reduced future maintenance.?

Thanks in advance for your response.
