question for you-all,
i'm out of silica to thicken the epoxy for filling cracks on my canoe(just done stripping), i read that common flour(kitchen type) can be used instead of collodial silica for a thixotropic agent.
anyone else try this? I'm filling cracks in white cedar so it will be a very light-colored fill.

thanks !

I have never heard of using it.
The flour I use is the wood flour which is nothing more then the fine dust gathered from sanding the wood. I have used some from the band saw after it was sifted thru a piece of screening to remove the splinters and larger pieces.

The only use I know of for normal flour (kitchen type) is baking , making gravy or using some on a cut to stop the bleeding.

Not much help ... am I ... Hopefully, someone on here has a better answer for you.

Chuck.

Flour

I recently had the same problem. I mixed regular flour and fine sawdust from the belt sander. Mixed it up in a food processor. It seems to have worked just fine. Different color then the maple wood from Raka though.

I used kitchen flour before (late one night after I had run out of wood flour). It worked pretty well but it will sag much worse than silica. I had a bit better luck with talcum powder.

There is a site on the net that says flour will work just fine for making fillets. ( He actually builds boats too!).
