Dicor non sag caulk probs
Anyone else use dicor’s non sag caulk on vertical surfaces that are under stress? I let it cure for 10 days and drove a 6 hour trip and it split open. I also noticed it’s still soft. [emoji849]. Did I not let it cure long enough? Wonder what I did wrong. It was 65 degrees out when applied. Any suggestions? I’m parked at state park as host for a month and wonder if I do it again if will set before we leave in 28 days or it’s just this caulk is not any good. Thanks for any advise.

I've tried that.
It's worthless. I spent so much time stripping and re-doing caulking on my RV.
I'd recommend using Pro-Flex RV sealant. Honestly, I think the White (if you have a white camper) is the best. My local dealer just has Clear whichnis ok.. I think the White is harder and more durable.
My camper is white so I don't know about the Black or Tan stuff.. it may be good too.

BTW.. i've found that the 3M Adhesive remover (it's in an aerosol can) is the best at removing the stuff. A little bit of elbow grease and a plastic putty knife (and rags) work well.

Omg. I just got done doing a s_it load of caulking with it. [emoji849][emoji849][emoji849][emoji849]. Do you think since it’s only been a month I can caulk over it with proflex? I did have to recover two other sections that split after trip to get inspected [emoji849]. Those areas held up on this trip. They did cure longer. Thanks for all the advise.

I used dicor non sag sealant but with movement and change in temperature l would see small cracks, l had removed all the old sealant and replaced it with new sealant. I cut done some Eternabond to 2 inches cleaned surface with acetone and placed Eternabond. The Eternabond is not noticeable.

I know the feeling.
I spent two sweltering weekends re-doing basically everything with the non-sag stuff only to have it all crack out the first time I towed with it. What a nightmare.
I did remove it all prior to putting on the Pro-Flex. The seal is only as good as the surface beneath it.

I only used dicor on the roof. I too had not luck using it on vertical surfaces. I used ProFlex.

Well. I asked. [emoji849]. The good thing now is I guess the crap will just scrape off easy cause it’s soft. Mineral spirts tears right through it to take off what’s left. 007. What did you use?

See post #3.
3M Adhesive Cleaner, a plastic putty knife, rags, and some elbow grease.
3M 08987 General Purpose Adhesive Cleaner, 15 oz. https://www.amazon.com/dp/B0002NUO6K..._3geZCbWKNWTPG
It also works for getting off Pro-Flex which is much harder than the Dicor Non-Sag.

I used the non-sag to seal my solar panel connection box and it was done inside in 70 degrees and cured for a month and it split before I even moved the panels. Sorry to say the stuff is junk!

I like "Lexel" caulk. It comes in clear and white. It will stick to nearly any hard surface. It is VERY tough, flexible and even paintable.

I have used Dicor on my old MH and just the self-leveling on the roof of the new one. I guess we will see.

For clean up and preparing caulking I used white gas, aka camp fuel, aka naphtha..... with extreme caution.
It dries quickly, leaves no residue, removes traces of old caulking and prepares existing caulking (that is in fair condition) to be covered over.
This is what many of the repair pros use and I have used it for years myself....with very good success.
I prefer ProFlex 'Bright White' (not the just 'White') as it is whiter and stays more flexible....on vertical or horizontal seams/joints...
However ONLY DiCore on the rubber roof areas...both leveling around fixtures and non-sag on edge seams where you don't want it to flow.
Hope this helps

I've been using pro-flex as well when re-doing the vertical surfaces. Works great.

Sorry to jump in but I literally have the Dicor self leveling white caulk in my Amazon cart to order today and started reading this thread. I am replacing my bedroom vent with a fan/vent (Maxxair Plus 4000) and then adding a Maxxair vent cover on my 2016 Sunseeker. Am I using the correct caulk for the roof? Also, are lap sealant and self leveling caulk the same? Thanks. Kevin

You got the right stuff. On the roof the self-Leveling stuff is good.
