Dicor non sag caulk probs

Anyone else use dicorís 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 itís still soft. . Did I not let it cure long enough? Wonder what I did wrong. It was 65 degrees out when applied. Any suggestions? Iím 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 itís 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. . Do you think since itís 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 . 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. . The good thing now is I guess the crap will just scrape off easy cause itís soft. Mineral spirts tears right through it to take off whatís left. 007. What did you use?
