Dicor or Sikaflex for around antennas?

September 13, 2017, 12:27:21 pm

I am getting some leaking in the area of my antenna farm. The existing caulk/sealant is stiff. Do I use Sikaflex or Dicor to seal them up?

My (limited) understanding is that Dicor is self-leveling which may not work around the antennas.

Dicor also makes a non leveling caulk have used it and works well.

I replaced my antenna earlier this year and used the Dicor self leveling product. Looks good and has worked well so far.

I am not replacing the antenna at this point. I just want to seal up the leak. I think the flexible antennas bounced off some low branches and knocked the seal loose.

I am close to Tennessee RV and they do stock the stuff.  I'll buy from their parts department. I won't have them touch my RV again. Fool me once, shame on you; fool me twice, shame on me!

Fred, I would say you could use either the Dicor self leveling or the non-self leveling.

My vote is 3M 4000 UV.  It skins over pretty quickly and seems to attract less dirt in my experience.  I haven't tried Sikaflex.  Clean up as best you can in the area you want to reseal before you use anything

Knocked off my King Jack on a low limb, I'll use whatever MOT, or FOT use when they reinstall it.

For what it is worth: I had two broken plastic cable retainers up on the roof. I decided to replace them. I found some nylon cable retainers and thought-- they will not break.
I dug out the putty (for lack of a better description) covering the screws that holds the cable retainers, There was about 1/2" of very small diameter, rusty un-threaded body left. Totally loose in the holes!!. Replaced them with stainless steel lag screws. Put caulk down in the holes first, then caulked around retainers and "buried" the bolt heads.
