make sure you get the eternaprime spray and heavy roller too!

Absolutely, make sure you wipe the surface down first. I used Acetone. The first time I used eternabond, others on the forum advised me to clean the surface good with acetone or some other cleaner. Because I didnt see dirt, I just placed the eternabond down. Big mistake. Wipe it down with a good cleaner first.

If you follow the guidelines for installing eternabond, there is nothing better! Trust me, it has sealed quarter sized holes in my aluminum roof after I installed it properly.

i agree with 450Donn, I have used that on this new roof as needed and it doesn't start leaking as the sun here in Arizona Beats the devil out of rubber. I have only used it for a few places where i tore the roof with trees. No leaks for a few months and another about 3 years ago. Checked them and no sign of lift at all. Dan

Did the Eternabond "thing" last year on our MH....the stuff is great! As others have said, get the surfaces clean, clean, clean. Once you put the tape in place, it is VERY difficult to remove....so be sure before you mount it.

As WeatherTodd suggested, get the heavy roller that is available. It is a bit pricey...but it REALLY does the job of sealing the tape and rolling out the bubbles. Also, you might want to have a couple of sharp needles handy to puncture any stubborn air pockets. I also found it helpful to visit the Eternabond website and a couple of others before I tackled the job. Very good info....

Eternabond also

I still had air gaps under Eternabond right at the transition molding. I think EDPM liquid rubber (DICOR) is better than Eternabond

let us know how the semi annual reapplication process goes with the dicor.

sealing a seam with eternabond requires a lil prep and pre planning to get it perfect. Once installed... much cleaner and maintenance free seal than any caulk.
Most important is to cut your tape slightly longer and dont work from one side to the other. If youve never used the seam tape before... having a 2nd person will help you set the material straight. Dont pull the backing off the adhesive side til you are positive you can lay it straight.
If you are getting air bubbles its because you are letting the material lay itself. Once the stuff touches... youre done for.
