Adseal To SikaFlex 221, Can Or Should It Be Done?

I have a 2019 Globetrotter with an interior ceiling leak that I think is coming from the bathroom vent/fan. I have spent hours searching the forum about
sealants but can't find advice on how to handle an Adseal leak.

Should I remove the Adseal and reseal with Adseal (Airstream tech support recomendation)? I've read many comments that silicone will not adhere to silicone, and that SikaFlex 221 is a superior sealant. Can the Adseal be removed (with what) an SikaFlex 221 be used in its place?

Much of what I've read about Adseal was early impressions, now that it has been in use on Airstreams for several years has the conventional wisdom changed?

Thanks in advance for your advice.
Dave S

Why wouldn't you follow Airstream Tech advice?

Because the conventional wisdom on this forum seems to be that Adseal is an inferior sealant to SikaFlex, and that Airstream may have switched to Adseal for cost reasons. Some of this information goes back to 2014.

I was hoping to get an updated opinion from some of the more knowledgeable members on this forum especially concerning trying to use silicone sealant where silicone sealant was previously used (e.g. silicone won't adhere to silicone) and if Adseal to SikaFlex would be the better option.

It is my understanding that Sikaflex is not used on the roof, only below the beltline. Use Dicor to seal cracks and Adseal to replace the sealant. Info came from a dealer customer service seminar. Products need to be acquired from AS dealer as they buy up most of the available material.

It is also my belief that Sikaflex is a great sealant solution. Also, it can be difficult to find. Look to commercial construction supply houses as a source. That is rumor and may not be fact.

Read the thread as good info in response to all.

Good Luck with your research and keep us informed as to your findings. Pat

Just purchased several tubes of Sikaflex; white and beige(to match my Argosy).

I think I have tried every silicone based caulk known to man and have yet to find one that doesnt eventually mold or crack.

I dont have long-term experience with Sikaflex, but first impressions are very good- it is urethane based, the white is BRIGHT, it goes on shiney and stays that way. The only down side so far is it takes overnight to set, so you really need to apply it and leave the area so you dont mess it up.

There is one Ace Hardware in my area that carries the full selection of Sika products in a separate display, so it may be worth calling around.

Oh, and their construction adhesive is fantastic too

I have used both Sikaflex and 3M Marine Adhesive Sealant (also a urethane sealant) on the roof of our trailer. Both have worked well and both are available from Amazon. The 3M product comes in various colors, but Amazon seems to have mostly white. Amazon has white, aluminum gray, and black in Sikaflex as well as some other colors in a slightly different product.

Urethane sealants adhere well and remain flexible. I have no reservations about using them on our trailer. I mask carefully and wear nitrile gloves when using Sikaflex. It seems to be able to get on everything if you are not careful.

Yes it's under warranty and I do have an appointment at the mothership at the end of July for a couple of other issues.

We have 3 camping trips coming up before that, the first one is in in two weeks. No chance of getting an appointment with anybody before that, so there is no time like the present to learn how to fix roof leaks.

I have Adseal on order from Airstream and am ordering some SikaFlex today. TBD which I'll use.

I have read that thread, it is one of the most current on the use of sealants. It's posts #5, #6 and #12 that have me concerned. That same basic information has appeared in some older posts. I believe it was lewster in an older thread also said that Adseal does not adhere well and is eaisly removed.

I might just end up sticking some bubble gum around the vent for now

Me, I would use which ever product airstream used originally, it keeps the majority of airstreams dry. They have missed something up there and you just want to solve your problem not create more. I donít know about the compatibility of the adseal and sikaflex. I am making the assumption that the engineers specked that product for a reason but the owner is right by default so use what ever you want and let me know how you make out Incase mine develops a leak.

Hope the leak is easy to locate!

Regards,

Larry

Me too....

I've switched to 3M 5200, because I'm old and don't plan on spending any more time on the roof than is absolutely needed.
Some say, ' it's so hard to remove,' but isn't that the point?
I re-sealed with it 8 yrs ago, still intact and pliable.

As a suggestion, which was a quick fix for me - the vent in our 2017 FC 25' FB bathroom was dripping during a rain - I went up on the roof and removed the smoke color plastic cover. Several of the screws holding the vent in place were loose, I tightened them. PO had put clear silicone around the frame next to the roof that was not done very well - I removed and cleaned that and applied a new bead of Henry 100% white Silicone Tropicool roof sealant. Also the sponge/foam seal had somewhat deteriorated so I replaced that as well. Problem solved - took about 30 minutes.
