Kevlar Repair - What Epoxy

OK........I was told to use 105 / 205........whatever the HELL that is....   Undecided  Undecided


I guess this stuff sets up pretty quickly.......so I need some other ideas.

1).  Is that the stuff I should be using.......if not WHAT.

2).  Are their other options.  I've read a little on west's website, but I'd like opinions from those who have done it.

I'm headed out later today to get the stuff.......any help would be appreciated.

Thanks,

Geo

If you're in the TC's - I'd suggest you go over to Northwest Canoe and discuss with them. They sell cedar-strip building supplies and epoxy - and they do boat repair.  They'll point you in the right direction.

For West System - 105 is the resin , the 2.. is the hardner that turns the stuff into glue/solid.  There are different hardners for diff needs.

Recoating the bottom of a canoe isn't rocket science - but a really-quick curing epoxy might be hard to work with.

Thanks........

I was thinking the 205 is too fast...........I ended up getting both.....I figure I can use 205 to start with.....the "crack" repairing, and get a "feel" for how fast it will be.

After that, I figure if 205 is GOOD, I will finish up with 205, otherwise, I will move onto 206.

Thanks,

Geo

I use 105 which is the resin, and 206 which is the slower hardner.

The push down plunger pumps you see in the link also meter the resin and hardner. One stroke resin, one stroke hardner, easy. Just leave the pumps on, nothing dries out. It's ready the next time.

GeoF, One nice thing about the slower hardner, it gives you time to have your panic attack and still recover enough to still do the right thing.  Grin

Work on a small cut or area. Build some confidence in what you're working with and the time it takes. Keep your batches of mix small. Give it time to cure. No rush.

If you think your job is making you nervous. One of may first experiences was I cut a hole in the bottom of a brand new never been wet racing canoe to install a Andersen Bailer. Talk about measure twice.

Don't even think that one of those bailers will work in tripping canoes. Hydrostatic pressure is exponential. Even a heavy slower race team can keep it from working right, let alone a tripping canoe full of gear.

thanks guys...........

I started the process.............and I'm quickly finding out even the not so deep scratches are causing the kevlar to stand up........

I'm thinking after I do the first coat, I will need to go over the canoe and check for "standers" and shave them off.

I understand now about "pot smoke"..........WOW...........10 minutes and I had a freakin smokin, burnin my damn hand mess...........   Smiley   Smiley

BUT.......it is started.

Later,

Geo

Shave? Like with a cabinet scraper, safety blade or a Gillette Quatro?

Here's the West Marine options:

Yikes that stuff is pricey! Honestly, a syringe of the half or one hour (whatever) epoxy will easily coat the entire bottom of a canoe. Use a margarine tub for a mixing pot ... comes right off when cured should you wish to reuse it.  Wink

If you have trouble with the cutting/shaving kevlar fibers? Remember you can just wet the fuzz with a small amount of epoxy and tape it down with clear box tape. After it hardens, remove the tape and do your larger area coats.

So........how long should the epoxy still be tacky.............

I did the coat about 24 hrs ago, but it is not completely setup..........

Fingerprints still set in the epoxy..........just wondering.

Outside temps have been 50 overnight and 65 high.........got to 80 today........


Thanks,

Geo
