Epoxy and wood flour for bid pending holes?

post #1 of 3
Thread Starter 
I'm changing bindings on some old Troublemakers. I have some plastic plugs and/ or I can easily turn up some hardwood plugs at work.

However, I build wooden kayaks as a hobby and often mix up batches of epoxy thickened with wood flour. Anybody used thickened epoxy for fill binding holes? Anybody see a problem with doing so?

Cheers

If you're talking of flowable-type epoxy and thickening it to peanut-butter consistency  like one does to make  fillets in stitch-n-glue construction, then no, there is not  a problem; you could alternatively use a fine silica thickener and it would flow better.   Flow both better out of a glue syringe and better into a hole.

 

Most of the epoxies I see talked of here (meaning on this forum, e.g. Devcon, Hysol) are designed for ease of use and a relatively fast cure time.   The type you're talking about requires a bit of *ahem* commitment, in terms of up-front cost, in terms of learning to use the product and in terms of the steps involved with each application.  If you do decide to use silica thickener, you'd effectively be creating something very like a product known here as PC7/PC11 marine epoxy.

Agree. I wouldn't purchase marine epoxy and fillers for the sole purpose of filling a few small holes but I always have enough leftover mix to do the job. When adding hardware to a boat, a drill/fill/drill approach is used so that no water can find it's way into the wood core. I've never used silica before as it adds another level of respiratory risk that I can do without.
Thanks for confirming my thoughts.
I'll be mixing up a batch in the next couple of weeks to do the hatches on my latest project and will fill the holes then.
Cheers
