Hello all, are you all using the Trempro 645 to reseal the outer seams, windows, etc or something else. I ran across the post below on another forum and found it interesting. Any thoughts on using marine caulk? I probably would not use it on the roof as they did. Thanks, Scott
"The marine caulk mention was probably me. I try not to get on my high horse about it but it's a challenge. I just don't know why silicone has a place in this industry. I'd rather do it once and be done for several years. I have refurbished and modified boats and travel trailers, and maintained a couple of motorhomes. Adhesive caulking will out-perform silicone every time. Marine caulk is adhesive caulk which can withstand below water line conditions. I have used it on RV's as well as boats. I re-caulked my boat's through-hull fittings last year after 17 years - under the waterline.
After week 2 with my 2022 GD, I had to go on the roof because there was a damp spot in the corner of the ceiling above the entry door. As is very typical, the caulking along the metal trim and roof membrane had already cracked. In the rear, the self-leveling caulk could already be peeled up along the edges.
Normally, I would remove all the existing caulking first but I wasn't in a position to take that much time. I just ran a thick bead of adhesive caulk (I always have marine caulk) and smoothed it out with my fingers making sure the edges had good contact with the membrane and the metal trim, but directly over the top of their previously installed caulk. (I should mention that I did clean it well first.) This stuff sticks, even to the existing caulk - but not silicone. 1.5 years later and no cracking anywhere. I would like to take the rig to RV Roof Install and have a proper roof put on. But in the event I don't do that in the next year, I will take the time to clean off the old stuff and redo it all.
Some will argue not using appropriate recommended "compatible" (yeah right) products will void the warranty. My philosophy is that I'm up there because their inferior product or application isn't holding up after week 2 so why would I want to maintain that for the next year or however many for a warranty? I won't have to worry about water leaks if it is sealed properly. The only warranty work I would bring it in for on the roof is when those bubbles all over start billowing in the wind due to inferior application of the roof membrane. If they try to tell me the caulk I used along the edges or around any fittings voids the warranty for the middle of the roof membrane billowing in the wind, well I'd like to understand that logic. Anyway, they can keep their warranty if that's the case. I'll spend the money to get something done right myself.
