Eternabond tape yeah or nah?

Looking at my roof today on my 2017 183 and I saw a few spots in the caulking around the max air vents starting to show little holes and cracking. Iím just wondering if I should go the route of the sticky gooey caulk that is around all vents and areas to seal or go with eternabond tape? I have heard good things about it but never used it before. Let me know the good the bad and the ugly . Thanks

I taped all my seams with Eternabond. It isn’t hard, though it takes some time and you need to prep. Done properly it will last a long time.

Here is my story from over 4 years ago...

I have heard from many owners of trailers they have done the same thing...

use Eternabond dot com as a reference tool with their information

https://www.forestriverforums.com/fo...nce-90060.html

You do not need 6 inch when 2 inch will do the job... you decide... it WILL STICK no matter which width you choose...

I did the same on my 2011 Dynamax. Clean surfaces & stick down Eternabond or Dicor everywhere there is caulking.Click image for larger version

I used the 4Ē. It covered all seams well, and I think 2Ē would have been too narrow. I ran two passes only on the front seam, as it barely covered everything with one pass.

I’ll use Dicor where just touch ups may be required. If I lot of rework is done, and I have to remove all the old Dicor, I’ll usually redo it with eternabond.

I did my roof, including front and rear end caps, and around all roof penetrations, the 4th year I owned my TT. I used 4" tape. After 4 years none of it is coming up anywhere and everything is still sealed up tight. The next RV will get it done the first week that it is in the driveway.

A good cleaning and prep according to instructions is vital. Don't try to skimp on either.

Many members have done their RV the first year of ownership. I did mine the second year after learning about Eternabond. I purchased a 6"x50' roll, cut off 2- 8'6" pieces for the front and rear caps, then split the remaining length to 2- 3" pieces for the sides. Another 4"x10' for around skylight, vents and other protrusions.

I did the same last year. Roof leaks are the death of RV's. I used 4" around every hole in the membrane, all along both sides, as well as 2 layers on the front and back seams. Last weekend, I put down 3 coats of EPDM acrylic coating. I think I am good for many years now.

What product did you use for the coating?

Thanks for the pics! It looks great. I'm getting ready to do my roof, but I''m unsure how to neatly do the sides. How did you do the sides? How far down did you go? Did you pull up any trim? Could you include pictures?

Thanks!

Also tape the 3 exposed edges of your slide outs so that it covers any trim/screws on the sides. The screws on top will back out and penetrate the original roofing. The extra layer of Eternabond is cheap insurance.

Eternabond

Just take you time, once itís down itís down and hard to remove. I did mine with 4 inch about 12 inches at a time, and prep is the key . Lots of YouTube on how to do it.

Dicor, two step system. It took 2 of the step 1 bottles to do my 30' trailer, and 3 gallons of step 2 for 3 coats.

Only things I took off were the vent & fridge covers. If you're talking about the 4" tape, along the sides, I tried to have enough to curl 1/2" or so over the side. It got kinda ugly in spots because you get no second chance with this stuff, once it touches the roof it isn't coming off. I suppose you could remove the trim and go under it, but you run the risk of not getting the rubber back down right.

If you're talking about the coating, you have to protect the camper from the step1 product. It can really mess up your finish.

Sealing roof vents, etc.

I would only use eternabond on an area or something you will NEVER have to replace. I've replaced vent covers and shower bubbles and getting dicor off is bad enough. Why? Hail and sun rot of covers will have you doing replacements.
