Dicor roof sealant is messy

Well today I got up on the roof to make sure all was well before we take our next trip. Not too shabby. Needs to be cleaned but could be worse.

I did notice a little bit of the old sealant at the back seem was starting to peel up a little so I starting pulling to see if it would pull off in a little area but of course 30 minutes later I pretty easily had the entire back seem of sealant off. So, time to put some dicor self leveling lap sealant on once the old stuff was completely cleaned off.

I guess my comment and or question is this. It doesn't have to look pretty right? As long as it goes on and doesn't leak? I have used the stuff once before and it never fails. It always looks messy and never as good as the original sealant looked and it ends up all over my hands. Is there a secret to stopping it from oozing once it starts!? That stuff is a menace but it "seems" to work. ;)

  • As long as you stop the leak, it doesn't matter if it's pretty.
    Wear disposable gloves, it is messy. I've found that releasing the tension on the caulking gun helps a little, but it still comes out.
    Come up with a plan before you start and do as much as possible without stopping. But, it's still messy.
    And I agree, use the Stick 'N Bond tape or Eternabond where possible. It's a one time repair.
  • On my front and back seam I removed all the loose stuff. Cleaned it with mineral spirits. Allowed it to dry. Applied Stick N Bond tape over the entire seam. That is the newer tape made by the same company. It seems to work well. Seems to hold up on the seam better than just Dicor. Also does a litt neater job. You have to realize the guys putting Dicor on at the factory are doing it 8 hours a day 5 days a week. Nobody can see your roof anyway. My patch jobs don't look perfect either. Main thing is to prevent leaks. We get better as time goes on.
