Will this work over old silicone caulking?

Silicone is about the only thing it won't stick to. You will need to remove the silicone & clean the area with a solvent such as acetone prior to application.Instructions come with the roll and clearly outline this.

Don't know for certain.... Never tried that myself, but it will certainly stick to any clean surface EXTREMELY Well, so as long as it completely covers the old caulk, I would think it should work fine, based upon my experience.

This would determine exactly what application you were looking to use it for. I'm not a chemist, so I can't speak to it's bonding properties, but this stuff will stick to just about anything. I used it to seal the seams on my aluminum RV. I first removed as much of the old sealant as I could, and then used acetone to clean the surface. It's not that hard to use, but once it makes contact, it's pretty much down for good. You can't lay it down and then pick it back up. It's only been 6 months since I put it down, but we've had a number of heavy rains and there hasn't been any signs of leaking. Not sure how it will do over a wide bead of silicone, but if it's just a narrow bead, you should be fine. This would determine exactly what application you were looking to use it for.

Yes and no. It will not stick to silicone at all. But if you are using the 6 inch wide tape, it will usually overlap all the silicone and stick to the RV. I used it over top of silicone that was about an inch wide, since the tape overlapped it by 2inches on each side it was fine. It did not stick to the silicone underneath the tape though.

yes, but it is preferable to remove and scrape clean before using. you need to use a putty or silicone sealer to flare out the sides to make a proper waterproof seal.Ron C

I believe it will, but advise scraping as much of the old off before application of Eterna-Bond. Silicone caulking should have NEVER been applied to your roof. Eterna-Bond will adhere to almost any clean surface. It's never failed me.

I have tried about every type of caulk there is for various bath and kitchen uses. Lexel is a very superior product for adhesion and water resistance. It's main downside is the fact that it requires careful application and keep in mind that it does not have water cleanup. I use masking tape to mask both sides of the seam I wish to caulk. I apply a bead of the caulk and then smooth it out with a popcycle stick. This makes a round caulk seam and the tape catches the extra caulk that would otherwise get on the surface you wish to keep it off. Remove the masking tape carefully within a few minutes. You can remove excess caulk from hands or tools with paint thinner. Silicone caulk is another alternative but in my experience is not as durable as Lexel. Both however, are superior to acrylic caulks that do have water cleanup characteristics. Acrylic caulks do have their uses but when adhesion and water proof qualities are paramount you cannot beat Lexel.

I don't think siliconing it will give you a long lasting solution. You'd have to make modification to it just to get it to sit flush before siliconing it. I recommend using a dremel or dremel like product to cut out the old rust drain and then replace it properly.

We use this on our roof. I don't know about caulking. We have a 1995 sunrise Tt and our rv mechanic recommended this Dicor works great on seams and roof. No leaks. The roof is rubber not alum.

It might if the seam is easily covered by the patch. You have to really follow the directions and get the tightest seal possible. Worth a try. Not to expensive. Good luck!

You shouldn't have any issues, you'll need to pre drill, and use a high quality silicone sealant during installation.

yes it will. After removal you will have to clean surface with an adhesive remover. Goo Gone will work as well if you do not have access to commercial grade products.

I don't see why not if using the right box and proper caulking. Robert M. suggested using Arlington model DHB1W for this. I would check that out.

That's a good idea. I put mine up with clear silicone and it worked well. Good luck.

This gun will work fine for any caulk since there is a dial on the gun to adjust the feed rate of the caulk. There are 2 triggers on the gun which one is to apply pressure and the 2nd is to release the pressure. Hope this helps.

I read somewhere that you can so long as you clean the old caulk with acetone--or some other appropriate cleaner--first. However, I've never tried it. I took the time to remove the old caulk first, which was easily done with a small Sheetrock mud knife and a hair dryer. I did it in winter months so if it can be done then, it can be done anytime of year. Just take your time so you don't puncture the roof material. I cleaned my surface with a rag dampened with acetone (not soaking). I let it dry overnight and then applied the tape. No problems since! Hope this helps.

I have to agree with TonyD except I put mine closer to the inside of center, guess it's really up to you and the shape of the tub. Silicone caulk works the best but can be bit messy/greasy to clean up, the key I found is to not to try and wash it off but instead get an old towel and wipe the excess off your hands and fingers after you beaded the seams or use latex gloves which are cheap and handy to have around anyways. Other than that it was an easy install and they work like a charm now.

It solved that problem at BOTH of my garages. The only trick is sealing the sides of this strip ... to keep water from running to the end of it, and then into the garage. I used silicone caulk. Oh, and make sure you glue it down correctly (per instructions), so water doesn't get under this strip.

No caulk is needed, but it wouldn't hurt. Just be careful of the threaded plastic adapter, as it can be easily crossthreaded.

I coated a fiberglass roof, not the seams. I would think a caulk would work better for seams.

No. It's great stuff. If I need a clear caulk, typically on glass or plastic, Dap Kwik seal is very good.

It might help somewhat, but I think something made from silicone would be a far better solution. Good luck!
