Ice damage this winters broke the seal between my bulk head and the bottom of the kayak- now I have a leaky forward compartment. Can it be repaired with any good silicone sealer or does it take a special kind of flexible sealer?? Any ideas Thanks Wayne F *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Any ideas >> Silicone is not recommended, in case you later need to do a major fix of the hull -- polyester resins (and epoxies) do not stick well to surfaces that have had silicone on them. Depends on what the bulkhead material is, but 3M 5200 is commonly used for this application. It comes in a fast(er) cure and a regular cure. Either kind should work here. Getting the old joint clean and abraded will be tricky, but the 5200 is a good gap filler, so it is OK to erode some bulkhead. 5200 is at the local marine supply store. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

3M 5200 sealant. I just removed a bulkhead that was installed with 3M 5200 and the only thing that would take it out was a Dremal tool with a cutoff wheel. Seals great, very strong, and flexable. wrf_at_CISUNIX.UNH.EDU wrote: > Ice damage this winters broke the seal between my bulk head and the > bottom of the kayak- now I have a leaky forward compartment.

A lot less expensive then 3M, and does the same thing. td376_at_mail.anonymizer.com wrote: > 3M 5200 sealant.

Then the silicones from the aquarium sealer will make adhesion of either epoxy or polyester resin difficult or unreliable.

I didn't notice any mention of the hull material, but would suspect that this is important too. Are you guys talking of fiberglass or poly? How about good adhesive for poly - not necessarily flexible?

How >about good adhesive for poly - not necessarily flexible? We were discussing composite boats, I think: FG with either epoxy or polyester/vinylester resin as part of the matrix. By "poly" I assume you mean polyethylene, as in rotomolded boats? I do not have a good answer for gluing bulkheads to polyethylene. Polyethylene does not take well to any adhesive I know of. In my experience, by horribly roughening the surface, contact cement works OK for minicell for padding, and 3M 3532 works OK for low-stress applications where the hull will not be flexed. I would guess if the bulkhead material is tight fitting, 3M 5200 or silicone sealer would be equally "good," but not very good. I have seen a handful of polyethylene boats with bulkheads separated from the hull ... probably because of rough handling in surf, or some other interaction that caused oilcanning. I'd be curious if others have solved this problem. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

>....the seal between my bulk head and the bottom of the kayak- ...Can it be repaired with any good silicone sealer or does it take a special kind of flexible sealer?? Sorry if this has already been answered; I've been snorting Puget Sound salt water for 4 days and have been away from computers...woe is me! ;) It's best to stay with something compatible with the original system; that way if a subsequent repair is necessary, you're not limited. Using silicone will limit you to only using silicone in the future...and even it won't stick all that well to itself once fully cured. Necky uses Lexel clear rubber sealant on its minicel bulkheads. Some use the original resin. Contact your manufacturer to see what they use. 3M 5200 urethane adhesive/sealant also works well and is very tough.
