Did you remove any excess caulking before applying the Eternabond? Or did you just apply the Eternabond over top what was there?
Reason I ask, my current trailer gobs and gobs of caulk around all the seams, and places like skylights, etc.westend wrote:
I installed Eternabond on every seam and all the through holes on my roof. It is still applied like the day I did it and no leaks after three years.
My roof was unusual in that I had years of different sealers on it to try to stop leaking--silicone, acrylic house caulk, RTV silicone, roofing tar, etc..
I removed all that I could, mechanically, with a wire cup brush on a grinder (aluminum roof). I then went over each seam with mineral spirits and lastly, lacquer thinner. This left a very clean surface for the Eternabond. I used Eternabond Roof tape on standing seams, vent openings, and vent pipes. On the edge trim, I covered the plastic screw cover and all of the edge trim with Eternabond Webseal, a more conformal tape. The finishing was two coats of elastomeric roof paint. It still looks like a million $$$.
The tricks for using the tape are---hospital clean surface and pressing the tape with a hand roller. The roller bursts the microencapsulated adhesive in the tape. Pressing by hand is no good. You need to put pressure on the tape with a roller.
Another thing I learned about Eternabond tapes is that they make excellent screw sealers. When I mounted my solar panel, I screwed through the tape and it follows up the screw thread and covers the head. Marvelous stuff!
