Just a couple of comments from the 'field'.

I use cases of sealants each month. I have settled on Sika as the go to OEM as they have the best, most consistently performing product that I have used.

I use 221 in white for roof seams, 221 grey for windows, doors and general sealing on aluminum and 715, which is a silane terminated polymer (doesn't harden and crack) for major roofing seams and around protrusions like fans, vents, skylights, etc. as it is self leveling.

Dicor self leveling applies nicely, but is very high in VOCs and will start to show drying cracks within a year or 2 of outdoor exposure. I'm constantly ripping it from existing roofing on SOBs and repacing it with 715. The Airstream factory is also using SikaFlex 221 in white/grey/black on the newer trailers and Interstates.

One note of caution: the surface must be properly prepared and cleaned before applying any type of sealant. I use Eterna Bond spray cleaner prior to applying Sika products. They also make their own cleaner, but it is increasingly hard to find. DO NOT USE ALCOHOL if ytou intend to apply any Sika products.

Would acetone be okay to use?

I have used acetone in a pinch. Saturate a rag and wipe the area where the sealant will be placed. I have also done the same with brake/carb cleaner, but always place on a rag first.

Be sure to test on a small unobtrusive space first c

Just curious; why not alcohol?

Also, what is the "active ingredient" solvent (e.g., MEK, trichloroethylene, xylene, etc.) in the EternaBond spray and Sika cleaners?

I haven't gone into the chemistry of the cleaners, but Sika was adamant about NOT using alcohol under any of their sealants. It affects the bonding and adhesive properties of their products.

Thank you TinTin, an excellent source of information…should you find yourself with some more spare time a similar thread for maintenance/renovation topics could be: Chassis paint systems, replacement floor material, water/heat furnace…the list is unfortunately endless!

So much good information on these forums, some of it is hard to find. Summary threads on several topics could be useful for sure.

Well crapola! I used Alcohol to clean my surface areas one last time before I did my caulking. Guess I'll keep an eye on things.

I want to say this to anyone wondering, because I got extremely frustrated until I put two and two together about the Silkaflex. It's an oil based product, and you'll need Mineral Spirits to clean up and wipe off excess.(Good job not putting any details about cleanup on the actual product) I started with a wet rag and was getting frustrated. Said to myself, this is behaving just like when I use a wet rag by mistake with oil paint. Sure enough, switched to mineral spirits and that was the trick.

The white Adseal and Loctite all clean up with water. And are much easier to work with in my personal opinion. I've done on/off construction work for the family business since I was 15.My finger has probably smeared more than 10,000 miles of chaulk along trim and I am particular about my caulk job. When I see it globbed on by folks I cringe. :P Working with that Silkaflex made me feel like an amateur.

FYI: I've been using cosmoline remover to to clean up the area before application of sealants. I also use it to to clean smeared parbond and silka sealants around the application area when the sealants are still tacky. I got the idea from one of the handy out-of-doors mart videos.

TinTin, just for accuracy, you may wish to change the spelling to 'Sikaflex'...the preferred weapon of choice in the marine industry, paramount to read their application data-sheets for compatibility, application, cleaning and often priming. (many of their products are not only used for sealing but also bonding so don't use it if you wish or need to dismantle bonded items on a regular basis, you'll break everything apart from the bond!)

Ps. Agree, the forum has all the information anyone could wish for, the problem is accessing it quickly...perhaps a 'wikipedia' design/type website would work..., or if the 'administrators' used the 'Stickies' for the 'best' topics?

Thanks, the spelling is corrected in the last list on the thread. The last list is the only one to read (hope people realize that).

Yep,

I was going to add that I regularly use SikaFlex 221 for bonding as well as sealing applications. The stuff IS awesome. Just be sure that you want what ever it is in the selected place, 'cause you ain't movin' it for nothin' or no how once it cures.

And BTW, 221 is a one part moisture cure polyurethane, which means that it will cure almost before your eyes in a humid climate (like FL). However, if you are in a dry/desert climate, it can literally days to go off.

I was doing some sealing in ABQ over the Ballon Fiesta, and the relative humidity was around 10%....now that's DRY! After 4 hours, the 221 hardly budged, so I started lightly misting with water and wrapping with a wet rag. Worked like a charm!!!!
