I've read somewhere that u can use regular baking flour in epoxy to thicken it up? This is mainly used when doing fillets and filling in holes. Any truth to this?

Re: adding regular cooking flour to epoxy?

You can, but there can be problems. The flour can absorb resin or moisture and swell up, causing porous fillets.

It's not significantly cheaper than eg. talc, and like talc or any powder filler it doesn't add any strength to the mix. It's just for thickening.

You can use it, but why do so if you can get cabosil or wood flour easily?

lol. I've heard of people using fine saw dust to thicken epoxy as well.

Yes, you can use wood flour and that is sold as an epoxy filler
