Repairing a canoe built with Tuf-weave

I need to repair a Wenonah WW II made with Tuff-Weave.

Can I use fiberglass s-glass or e-glass to make the repair?

Use glass for most outside repairs
and Kevlar or polyester for most inside repairs.

There are certain locations on the outside of the hull where the most likely recurring stresses (such as the bottom of the stern whumping when going over a ledge) may be better handled by Kevlar or even polyester rather than glass. And inside the boat, certain regions might need to be stiffened by glass or carbon rather than polyester or Kevlar. You have to visualize what sort of distortion produced the break.

Do yourself a big favor and do the repairs with E glass. It’s a heck of alot easier to work with and unless you’ve got a fair amount of experience (and tools) don’t think about playing with Kevlar.

Yes, and E-glass is always available
locally. John Sweet maintained that glass should be no more than three years old, because the coating on the fibers deteriorates so that resins may not adhere as well. But I know I’ve used older glass and I haven’t had any patch jobs go bad. And, I don’t know how one could determine the age of E-glass on store shelves.

S-glass is often tightly woven and harder to wet out. I’m using a very tight weave, though, and had no problem. Kevlar is easy to wet out, but you have to work in a good light so you can see the air has been squeegeed out of it.

glass coatings
New’er glass does wet out easier and tends to be clearer, makes a difference over wood. Keep it wrapped up and out of direct UV and it’ll last a fairly long time. I usually buy it in 100 yard rolls so takes a little time to use it all :slight_smile:
