Eternabond over sealant?

[Mickeyfan0805]

Our unit just turned 5 and is holding together beautifully. I want to keep it that way!

Over the past 5 years, I have done both spring and fall seal checks, placing self-leveling sealant over any locations where I found a crack. Now that the original sealant is 5 years old, I'm starting to consider moving to eternabond, but I'm not sure about putting it over the uneven sealant that is there.

For those of you who use Eternabond around your trailer, did you remove all of the sealant or simply place it over the existing and while making sure to get a clean seal on the edges?

Eternabond will stick just fine to Dicor. Clean the surface first, and use a roller to press it down.

I cleaned and inspected the Dicor sealant prior to applying the Eternabond. This stuff is very pliable and will completely seal over the uneven surfaces of the dicor.

When I did our front and rear caps I applied it over the existing Dicor. I did clean the area well before applying but did not see the need to remove what would be covered up.

Eternabond must be applied to a completely clean surface. Results would likely be unreliable trying to do as you suggest.
