Can this be applied over silicone? Just looking to beef up some joints on my RV Roof.

I wouldn't . If you don't have a leak then I wouldn't mess with it . Or I would remive the silicone and use the dicor sealant .

I think that a better resolution to your problem would be to apply strips of EPDM roofing materiel over the joint that you want to reinforce.So far as applying this over silicone, I don't know if that would work or not.

Nope. Silicone must be removed. Curses to anyone who used silicone as it is a PITA :(

No. This has to contact clean EPDM to bond and seal correctly. Silicone + EPDM = Leaks.

Tom, I love the eternabond but I was using it to fix seams on a metal roof. For that the best prep was Acetone but I'm pretty sure that stuff will not play well w/ your rubber roofing. I can't speak to how much you'll need because it really is based on the amount of dirt, mold you have. My suggestion would be to pick up whatever cleaner you'll need at your local hardware, home depot or lowe's and just return what you don't use. You definately need it as clean and dry as possible. If you put it on right that stuff ain't coming off. Hope this helps.

This product works fine on solid surfaces. BUT not on an RV EPDM roof. It may work if you use a primer with it and clean the roof first with TSP. I used this on a motorhome roof, without a primer, and did not get the roof totally clean, and it flecked off going down the road. But if you are doing a motorhome EPDM roof Iwould suggest the #63900 made for RV Roofs, and use the primer...

It works well on pure silicone. It might work on some silicone blends, but probably not nearly as well. A lot of exterior/interior house caulking are acrylic base and I don't think this would be the product for those types. I think the "big box" lumber stores have a remover for acrylic latex caulk .

The reason I chose this product is for its bonding ability to rubber roofing surfaces,many silicone products do not work well in this regard....Bonding to a rubber roofing material has been excellent!!!! Also recommended by the installer!!!

I am not sure what kind of roof this is. But ours was rubber rv roof and worked great. Still looks like new. It is for RV rubber roofs.

I used this specifically for my Coleman 12' fiberglass pop-up trailer roof. I bought (2) gallons and have 1/2 of second gallon still available. I rolled it on thick and imagine another 5-6 years of use before having to reapply.

Should work well, maybe brilliantly, as long as either the glass or the pvc is transparent enough to allow UVlight to cure the bond. I am a sculptor (in glass and metal) and for the work I've done Loctite 349 Impruv is peerless, stronger and cleaner than construction silicone

I certainly do not claim to be an expert having only used this product once, but it is so sticky, I think it would adhere to anything. Be sure to overlap it on to the remaining roofing to make a good seal. So far it has worked great for me. Hope this helps.

i have not used it on silicone sheet's and because it is a metal it's possible that it may damage the surface.

I suppose you could try. I only used it on the molding around the roof. It has good adherence.

yes you absolutely can... The stuff is amazing and well worth the cost... Here is a good instructional video that shows how to clean and install (http://www.youtube.com/watch?v=ZYwxEX3SBK4), I have repaired several RV EPDM roofs with this product and it is amazing... Cleaning of the surface is of utmost importance... If there is any dirt, grime, etc on your repair the tape bond will eventually fail...

I would recommend construction adhesive rather than the silicone adhesive. It will set up faster, be stronger & move durable.

On the instructions on the can it says it can be used on "some" tpo roofs. This product worked beyond great for me on my travel trailer and would recommend this product for redoing your roof for sure! Make sure you get the cleaner/activator (part1) . 1 bottle of cleaner/activator and 2 gallons of the coating did my 26ft trailer

No, Make sure you clean the heck out of surface to use epoxy on. Silicon residue will cause problems. Use J-B WELD EPOXY. Play with it first.

Silicone doesn't stick very well to plastic. If it sticks at all try using a long (about 2 inch) drywall screw to extract it. You can even put the screw into the nozzle while the silicone is still gooey and let it harden. Then removal is easy.

I used it on an a flat smooth RV roof. It does seal well but I have no idea about putting it over shingles.
