Has anyone used this Eternabond Tape for the seams on the roofs of their RV'S?

Lee C · 03-10-2009, 09:57 PM

I used Eternabond along the seam of the roof and the end caps and around the vents and the skylight. I didn't have a leak but did it as a precaution. It's really simple, just follow the directions and be careful where you put it because it "stays stuck". Eternabond has some video directions on their web site.

It is a good product. I have put it on many repairs made in the shop.

I put it on three years ago and have been very happy with it. It will go on my next coach as well.

I can't understand why the manufacturers don't put it on in the beginning. It would probably even cut down on warranty repairs which would make it cost effective.

i used the tape where the end cap meets the side and roof several years ago and it is still good. it has been used to repair rips in the awning fabric and it is still holding.

I have used the tape, with success. I will use it again. All around the rook, caps and all other openings in the roof.

I have a question about Eternabond as a follow-up to cadteach's question..I've done a search but can't seem to find my answer. DH and I are considering applying EB to the roof seams and skylight, etc (as Lee C did) as a precaution. But we're not sure if we should remove caulking first and then apply the EB or remove old caulking/sealants, replace with new and THEN apply the EB. Any suggestions?
Thanks in advance...

Hi Jeanne M,
My use of EB on the roof was also for prevention. I cleaned the places I was to put the EB throughly with 303. I applied the EB right over the factory installed caulk and seam cover strips. I used the 4" wide EB. Get the longest roll you can buy. This is the important step, lay a chalk line (buy it at Lowe's or HD) where you want one edge of the EB to go. You get only one chance with EB. The chalk line will help you keep the run straight. Start at the back and work to the front on all runs. This makes the overlap correct for the wind direction when driving.

good luck,

I do exactly what Gary does. I even used it to seal around the black tank vent where it goes through the roof fitting. There was a small gap there so that rain could follow the pipe down into the coach to who knows where. Not any more. It is a great product.

every seam on my roof (vents, sky lights, sewer vents etc etc) are sealed with EB tape. bought a 4in wide 50ft roll and cut it into 2ins which gave me a 100ft. all done just as preventive maintance.

I have replaced my old seals with EB and I can also recommend it.

Definately remove all old caulkin before applying the EB. Get a caulkin tool like this http://www.lowes.com/lowes/lkn?actio...389&lpage=none and remove all caulkin very carefully without doing damage to the surface. It is hard work but will pay off in the long run.

When finished the scraping you can remove the last small sticky bits with 3M general purpose adhesive cleaner: http://www.autobarn.net/mmm08987.html

Any small gaps in the EB can be covered with a suitable caulkin if needed.

Good luck with your project.

Used the 4" by 50' rolls to seal the roof seams on my DSDP. Newmar did not get too wild and crazy with the sealant so I just cleaned real good with lacquer thinner. Just don't let it pool on the TPO roof. 4" gave good overlap on both sides. Started from the back and worked to the front. Use a chalk line to keep yourself straight.

Hi Ho: I used 2-inch white for the motorhome edge seals. Seems to work well, but have only had about 3 years to evaluate. Also used 4-inch silver for a snowmobile trailer with roof that used to leak like a sieve. No problems for the last 5 years even with lots of snow and cold weather (to -35 deg. F.) Not even a drop of water leaks.

I like the stuff. Kind of expensive, but can be obtained online at reduced prices.
