Flex Paste vs. Dicor

[Skippy38]

Has anyone tried that new Flex Paste from Flex seal? I am wondering if it is a viable alternative to Dicor...

Dicor has a proven track record and works with all RV roof systems. With the Flex Paste I am not sure what it will be like in a few years in the Florida Sun. There only clime is "it will last for years".

You may also look at Durabond Tape, again a good track record on RV roofs. I am ordering some up to cover the transition between the front cap and the roof. To me it is a better option than removing all the old sealer and applying Dicor. This seam is not leaking so it is a preventive maintenance thing to cover with the Durabond tape.

I see they are running commercials with the guy paintring on the stuff on vent seals and such. I suppose it would work, For me I will stay with the tried and true method of Dicor.

Interesting note: Forest river is using tape to seal all the roof seams.

There is a good article on the Dicor site explaining EPDM and TPO roof materials and how Dicor is formulated specifically to bond with the material on a microscopic level. Somewhat self-serving but interesting nonetheless. I use Dicor and I am happy with the results.

Stick with the good stuff!
Leave that other miracle stuff for some guy to build boats from paper towels, chicken wire or glass.

I like how the Dicor performs, was just wondering if anyone had tried the Flex stuff. Like you, I taped the rear seams as a preventative measure but I taped it with the Quick Roof Ultra Bond tape that you get at Home Depot and not the Eternabond or Durabond brand. So far it is holding up well. Mine was not leaking either, I just figured it would be good to have another barrier against water. I will be taping the front seam shortly...

Skippy, it would be better if you explained why you have a need to use something else.

But wait, there's more! ARE YOU DOUBTING PHIL SWIFT? I am surprised all the RV manufacturers haven't gone to that spray can glop to seal roofs! I used some to seal the downspout on a gutter and stood on the seat of my tractor. The stuff blew all over and now the tractor is covered in white Flex Seal blobs. It won't come off. Didn't stop the gutter from leaking but you can't have everything I guess... :whistling:

Some of the "bonding tape roof products" are not compatible with TPO/EPDM roofing membrane. They react chemically with the TPO/EPDM to slowly dissolve it over time. I've no idea what you're doing to your roof with that brand tape or whether it is "chemically friendly" to TPO membrane. You may find that it "seals great, looks great, there's no leaks and it's cheaper to buy" only to find in 2-3 years that the TPO under the tape is "goo" and the way you noticed it is the sticky margins around the tape seams that are filled with dirt and pine needles.....

While it may work wonderfully and not cause any problems over time, on the other hand, you may have "compromised your TPO membrane beyond repair".....

Everyone is trying to build a better mouse trap, but there is still nothing better than the original. Don't let the glitz of theatrical performances and hype fool you. You'll regret it. Stick with the products that's specifically designed for what you have. Chemical imbalances between different substances can cost you a lot more than just a buck or two. You paid too much for your camper ... don't make short cuts in it's upkeep.

Hmmmm, reminds me of using blue Loctite threadlocker on screws through a plastic fender.....:facepalm: :banghead:

Mixing chemicals can have unpredictable or negative effects. Examples: while bleach will "remove blood stains" it will also remove most dyes from clothing as well. Paint remover will remove paint from your hands but at the cost of serious chemical burns.

I'm all for saving a buck but I'm not going to be the lab rat and test an "unknown" on my roof. Asking a question of this sort can get you an anecdotal response that may not reveal near term nor long term effects.

That would be helpful if I had a TPO/EDPM roof, but I do not. I have PVC roof and have had the tape on there for at least two years with no harmful effect at all.

[Skippy38]

Skippy, it would be better if you explained why you have a need to use something else.

I never said that I need to use something else. The original post was asking if anyone had tried it....

If you have a 20015 Cougar XLite with the factory installed roof, then it's not PVC. If you have changed out the roof, then that's an entirely different situation, however, there's no mention of that in your posts. Anyway, TPO and most "big box store roofing tape" do not play well together.... YMMV

ADDED: I'd ask, based on the original post and the "further revelations" whether we're being trolled or if possibly the goalpost is moving as the thread progresses ????

Exactly, who said I had a factory roof? I had a new roof installed a few years ago due to an "accident" lol, and they installed a PVC roof. I agree with you, my original question is whether anyone had any experience with the Flex Seal product, nothing about roofing tape. I never said that I used or was going to use the Flex Seal product....I just asked if anyone had any experience with it

If you want a "fact based answer to a question" it's always appropriate to provide all the information. As this thread "grows" you've added "just enough to keep the reader guessing"....

Trying to gather facts, provide them in a logical sequence for you, when you then "add a twist"... Well, use whatever you want and let us know how it works out for you :banghead:

[Gary R.]

The Flex Seal Paste website states the paste is safe for PVC, EIFS, EPDM, CSPE and more roof material.

Myself, I will stick with Eternabond and Dicor for our 5er.

Cheers!

I tried Flex-seal / Flex-paste on a fountain pot with a crack in one of the bowls and it lasted less than a week. Now, I've used Dicor products on my RV and it's lasted for years. Eterna-bond Tape is like magic and used in conjunction with self leveling and non-leveling Dicor caulk can't be beat.

[Hoopy Frood]

FWIW I tried using some of the FlexSeal spray filler to stop a leaking gutter on the house. I put on three coats, waiting for each to dry between applications. And the gutter still leaks.

I would not use FlexSeal anything on something I really wanted to protect.

All of my gutter seams still leak as well. I've got 2 to 3 coats of Flex Seal on all of them. This year, when it warms up a bit more, I'm buying a couple tubes of DICOR self leveling and fix my "gutter problems" that Flex Seal couldn't.

[Hugo-H]

I have some similar problems on my roof... but in the US they name products differently I see...
And since I want to care for my recently obtained 31 BHPR very much, I want to make sure I use the rights products and the right methods from the first time.
You mentioned about "removing" the old sealer and apply Dicor, while time ago someone told me not the remove the old sealer, but apply Dicor on top of it... what's the difference? (over time I guess...)

[JRTJH]

Hugo,

DICOR is one of the few sealants that will adhere to itself. The "general guidance" from DICOR is to clean the sealant beads, carefully inspect the margins and remove any "non-adherent" sealant by cutting it away "back to where it adheres to the surface properly". Once that is accomplished, wipe down the sealant surface with alcohol (or other approved solvent) to remove all contaminats, oils or grease that might have come from fingers, gloves, etc. Allow that to dry, then apply a fresh coat of DICOR sealant directly over the surface, overlapping the old sealant, allowing at least a 1" margin of fresh sealant in contact with the surface being covered.

DICOR self-levelling and DICOR non-leveling sealant are compatible with each other and there is no need to remove "all the old sealant". The company suggests that any "damaged or non-adherent sealant be removed before fresh sealant is applied to the surface.

It's my understanding that anything with silicone in it will not adhere to itself. I do not use any sealant with silicone on my RV "anywhere"... And, I completely avoid the $1.99 tubes of "latex caulking with silicone" for use on anything I own. Whether it's a "knot hole in an old lawn chair" or a loose piece of vinyl siding, that crap is exactly that: CRAP.

Dicor exists for a reason. The two different rubber materials used on RV roofs are also used for a reason. Why on God's green earth would you even want to risk damaging your RV's roofing material by "experimenting' with an infomercial "Johnny come lately" imitation. Dicor seals, adheres, is UV resistant and most importantly remaining very flexible for years. I just took off solar panels I mounted 6 yrs ago on our 2014 Jayco and the Dicor is still flexible. I think your are nuts using anything that the industry has not embraced. Roof leaks are the number one cause for an RV being deemed worthless. Don't even think the risk is worth it.

I keep a 25' roll of Durabond on hand just in case for emergencies. I used a clear Flex seal product on an awning & it turned yellow. You get what you pay for.
