Young Entertainer 59 Posted December 5, 2019 Share Posted December 5, 2019 any good ideas for some form of glue/adhesive that can be applied underwater, will be short term fix over xmas to glue a piece of rubber onto fibreglass, save me a separate haulout just to do this dry.

wheels 543 Posted December 5, 2019 Share Posted December 5, 2019 What is it exactly that you are trying to glue on and why?You are not going to get an underwater glue that will adhere to Rubber. Not that i know of anyway. Perhaps talk to one of the Glue selling experts.However, I do know of a flexible kind of product similar to rubber that is like a really thick (maybe 2mm thick) adhesive tape that will adhere underwater. It is used to seal leaks and comes in a really large size. Not sure who sells it, but I have seen it on TV, so assume it will be Bunnings or Mega10. Always thought I should get some of that, but never got around to it. Quote Link to post Share on other sites
Abel Seaman 19 Posted December 5, 2019 Share Posted December 5, 2019 I havent seen this stuff for years but it was impressive! https://www.marine-deals.co.nz/epoxy-resin-and-boat-repair/seal-once-sealant-cartridge Salesman applied a bead of sealant to a piece of polished stainless steel (that i gave to him from our stocks) while it was under a running cold water tap! we used it in wet industrial applications with good results. No relationship at all... Quote Link to post Share on other sites
boots 1 Posted December 5, 2019 Share Posted December 5, 2019 Knead it epoxy aqua at blackwoods Quote Link to post Share on other sites
wheels 543 Posted December 5, 2019 Share Posted December 5, 2019 Seal Once is not an Adhesive though. It will have enough strength to hold something not under any load, but under a bit of load it will pull apart. Kneed it will not adhere to Rubber. There are many Epoxy Putties that will stick and harden underwater, but they are too rigid once hard to be able to adhere well to rubber. Quote Link to post Share on other sites
Young Entertainer 59 Posted December 5, 2019 Author Share Posted December 5, 2019 it is a corner of my saildrive rubber, not mission critical but would like to stick it back to the hull for the break, no time available on the heard stand, but i am up for a half hour next week so i though dry it up as much as possible and put something on that will set underwater. Only has to last a month then I can do it properly Quote Link to post Share on other sites
wild violet 38 Posted December 6, 2019 Share Posted December 6, 2019 If there is water getting in your sail drive rubber would be wise to sort it properly.Could be very expensive to leave it Quote Link to post Share on other sites
Jon 340 Posted December 6, 2019 Share Posted December 6, 2019 He’s talking about the rubber boot prevents growth on the upper leg For what you want Craig I’d say any wet area sealant would do the job Quote Link to post Share on other sites
wheels 543 Posted December 7, 2019 Share Posted December 7, 2019 Be aware that no sealant is ever going to cure underwater. So what used is going to need to cure quickly before it goes back in Quote Link to post Share on other sites

whitepointer 32 Posted December 10, 2019 Share Posted December 10, 2019 after advice from a boat builder I glued my SD20 fairing rubber on with 3m 5200, 5 years later still looking good with no edges lifting Quote Link to post Share on other sites
