Put a ding in my SR Q17 on the Pigeon River last fall. The damage is right beneath the rear paddlers left butt cheek :)

I have watched Red Rock Joe’s YouTube videos on how to patch cracks. Looks fairly DIY friendly.

Would someone here be willing to look at photos and give me advice as to how to approach a patch? Never tangled with this before and just looking for some pointers.

I attached some photos. I’ve got the canoe out, so, if more pics would help you help me, I’ve got easy access.

Thanks,

Mr B

Sneak up from a dark side!

So much for silly. Looks like a dent no fibers cut or holed hull. Looks like a refinish job no patch, just soak some epoxy into the fiber layers.
Clean it up well, very light sanding (frayed kevlar is kinda kinky and hard to work with). Mix up some goo of your choice, West Systems Epoxy is a good start, brush/roller on the repair let it set up. I'd do the inside also after the first side is cured.

That's a simple repair. Looks like the Kevlar is cracked all the way through to the inside? If so, I would put the structural patch on the inside of the hull and just smooth over the outside with some epoxy.

Haven't watched the video you refer to but I'm assuming it has all the necessary steps needed. Cover the wet epoxy patch with Saran Wrap/Handy Wrap to make a nice smooth surface finish.

I would agree with BeaV. Inside patch.

You folks are the best!

So here is my plan so far.....

Sand and cleanup inside area for structural patch.

First apply a Kevlar patch then a fiberglass patch over the top of the Kevlar patch?

So it would go like this for the inside patch?

Goop->Kevlar->more goop->Fiberglass->last layer of goop

I'd only add a patch if the area was punctured or cut/broken or real flexy, but hey it's your canoe. My though is if a surface application works that is less weight and material build up, can always add latter if it's found to be weak. Easy on the goop, a little goes a long way. All ya want is to saturate the cloth/fibers with a layer of epoxy apply then squeegee off the excess. If your going to add a patch just fiberglass one layer should be fine.

BeaV's saran wrap, is a good idea and I have used it often.

I won't be able to physically help, but I could mosey down and kinda help after surgery seeing how I'll be limited.

I patched a similar place on my Magic a couple of years ago and was advised by Northstar to do what has been suggested here, patch on the inside. My Magic is the White gold layup so I used Gel Coat on the outside and glass on the inside. If you use a layer of glass don't forget to put on a coat of urethane or spar varnish that has a UV filter or the glass will turn white.

Nctry- I’m not opposed to a little expert advice :) I’ll try and keep you posted as to when I’ll be doing this. Sometime soon though. Heading to SAK on May 16th.

Butthead- the crack feels more flimsy than the rest of the canoe. I don’t doubt that I could paddle it as is the whole season and probably be fine. I just enjoy tinkering and learning.

To the rest.....thanks for intel!

As butthead stated, go easy on the goop(epoxy) especially if you go with 2 layers- it will build up quick and be thicker than you need.

Make sure you wet the fiberglass or Kevlar before sticking it in the canoe. Then apply just enough goop to the canoe surface to wet it before sticking the patch on. Assuming you're putting the second layer on while the first is still not cured then you shouldn't need more goop in between layers. After you stick on the second, apply only enough goop to smooth out the patch. Apply Saran wrap and stretch tight/smooth out.

If you do two layers make sure the first layer is smaller on all four sides. Like a half inch on all four. This way the Kevlar is bonded to the canoe. Then the glass is bonded to the Kevlar as well as the canoe. Much stronger repair this way.

Thanks for all the advice folks.

Received the kit today.

Might try and sneak out these next couple of evenings, after the kids go to bed, and get the areas sanded.

Question......

Since I will prob have a bunch of the resin left over at the end of the project, could I use this same resin to repair other dings?

The portion of the keel that collides with rocks upon beaching shows a little wear. A little groove slowly forming at the point of impact. Could I use some of the epoxy to fill this void?


A small, like 1 1/2 inch long, tear in the fabric on the vertical wall of the front float tank. It’s in the corner where the the front float tank wall and the paddlers right side wall meet. Right in the bend where the 2 parts meet. Should I slather a little on there?


Again, thanks for all the advice!

Yes, you can use the leftover to fill other dings. Saran wrap stretched over wherever you can does a good job of smoothing. For your bow repair same applies although you might need to build up in multiple layers if you're using the resin neat w/o any additives.

Curious why the FG on top of the kevlar patch?

Lastly, if you have leftover fabric why not do a patch on top of the tear on the float tank? It'd probably be longer lasting then just applying epoxy to it.

Good point on the float tank. Think I’ll cut a strip to put on there also.

Surgery was today. Very very sore. They somehow torqued on my bad shoulders and now that of all things GS is extremely painful. But as soon as it's can travel, I'm heading down to big sandy to try and catch you Jeff.

Ben- Sounds good!

Decided to finish up the syrup operation for the year. While boiling decided to just do the patches. Not pretty but, made the boat stronger. While working on it, I found a couple more dings I want to touch up. Ordered some more epoxy.

Evidently, the Porkchop Express (my canoe) needed a little more TLC than I thought.
