kevlar canoe repair

5 posts in this topic

i have an 18 foot kevlar canoe that has a "crease" across the bottom, width ways, that needs to be repaired. there really isn't any rips in this spot but it does need to be fixed for the strength. I think the repair should be easy enough but my question is....I was given a rather large repair kit for a fiberglass canoe,resin and the epoxy, but am wondering if this will work on my kevlar canoe.bonding and strength can post? pics if needed to understand the scope of the work.if not what are my best options in S.E. MN? would consider paying for repairs but would like to do it myself.

If I remember correctly, you can use polyester resin over epoxy, but not the other way around - so I think you can use the fiberglass repair kit. You can also purchase epoxy resin online if you want to use something more like the original resin. You can use the fiberglass cloth that came with the kit you have. Depending on the brand of canoe you have, some of the manufacturers also use what is called a "vinylester" resin, which is something a little different again. Marine epoxy resin is available through suppliers who sell wood boat kits online.

Its the other way around you can put epoxy on any thing but only more epoxy on top in the future. Once epoxy is on no paint, polyester, vinylester will stick to it. The poly and vinylester are simalar. If your canoe is gel coated or colored its probaly poly/vinyl. If its natural it could go either way poly or epoxy. Its pretty easy to work with either way, you won't have any troubles. Good luck

Here is a link to Joe's Red Rock Store HSOforum that explains patching kevlar;

I don't know if it helps you out or not, but there are some other links as well dealing with kevlar. I haven't had any problems with my kevlar yet, but I found Joe's stuff to be interesting reads.

Yes - the Souris Rivers are epoxy resin, aren't they?

So I think it would be a good idea to find out for sure what kind of resin was used in the original layup before you repair it.

    • No where yesterday during the woman's march was there violence or racism exhibited. Intolerant towards things Trump wishes to eliminate yes. The damage by vandals occurred on Friday by a group of thugs who had only one purpose in mind and that was to destroy property and create trouble during the inauguration. (DC police even said that and they expected it.) Yes the Woman March did leave garbage to clean up, which can be expected. If you have ever had the experience of cleaning a (female) public restroom you would find out they have a problem with garbage cans. I'm sure most did take their signs with them in the same manner most ice-fisherman take their garbage off the lake with them, but there are some who don't. The top photo is the only one that is of the Woman March.   
    • Can you explain why you feel that way?    
    • I do believe you are out of line with the racist, intolerant, vandals comment.
    • I will slow it down. I did not say you said it was rigged. Your party,however went after Trump for not saying he would accept the election results and then turned around and in large numbers proclaimed they didn't accept the results. I don't expect you to understand the hypocrisy of that but at the same time it's there.   Conjecture. You don't have a single slice of evidence this is the case and you would be wise to retract it because it has no basis. None. Yet even though this is the sort of thing your party is outraged about by the right, you are actually more extreme about it on your side.    While there is direct evidence that the DNC blatantly rigged the Democrat primary in favor of Hillary and committed all manner of things that came out in the Podesta/DNC emails there was no outrage on your side over what they did. Yet you jump on Trump for something that was sold as truth when it was literally the same fake news the Dems have been pushing all cycle.    Considering the contributions that flowed into the Clinton campaign coffers in all manners it would be best to leave that sleeping dog lie.    In the meantime. you might want to take ownership of the mess that the racist, intolerant, vandals that made up the protest marches because you own that.    
    • i always thought they were about identical smoked  
    • Rumor has it they are running a story next week regarding ice fishing and CO. 
    • Looks like one to me. Nice catch  
    • I thought you lefties were against fake news.   Guess not so much anymore.   At least you haven't attacked Barron Trump, yet, unlike your fellow travelers. 
    • When did I claim the election was rigged? It was influenced by Russian propaganda and you have a President that is in all likelihood blackmailed by Russia.    And that is equivalent to some Saudi's donating to a charity somehow? Note that Trump's charity was shut down because it funneled money directly into Trump's pocket.
