Wood flour alternatives

[steve71]

Hi, I was wondering if there were any alternatives to using wood flour as a filler for making epoxy glue. I have tried using water putty in its dry powder form with silica but not happy with its lack of ability to hold without sagging. Is it just a case of putting more silica with it? When I use the 70/30 mix ratio as used with the wood flour to silica recipe I find it is just not holding even though its consistancy is like peanut butter.

Can Durhams water putty be used as a filler? (just in case nothing else is readily available?)

Gougeon Bros have a whole selection of fillers that can be blended to produce exactly the properties you want. I know that West Marine and Hamilton Marine both carry the entire range. Your local marine supply probably does as well.

Many thanks for your reply!

Jamestown Distributors TotalBoat sells a thickened epoxy that is wood colored, in a nice caulk cartridge. Saves a lot of time but costs more, plus you get the right consistency mix every time.

I've used TotalBoat's wood colored epoxy for different uses, some heavy duty, and it never failed me; I can recommend it without hesitating!
