Hello fellow woodworkers. I have a project that I’m going to attempt which will require filling some pretty good size cracks. I know the current rage is to fill them with epoxy, which I have done. My question is with the high cost of epoxy has anyone tried to fill cracks with a mixture of sawdust and wood glue? My thought is to fill the deep cracks most of the way then finish the fill after it dries with epoxy. Anyone try that method?

I’ve done this with titebond 2 with no issues. I’m sure it goes without saying but make sure the glues fully dry first. Can’t speak for any other brand

I have had good luck using CA glue and saw dust.
I found that I could pack the crack with fine sawdust as tight as possible. Then quickly soak it with the thin CA glue, immediately followed with medium or thick CA glue. The thin glue acts as a wicking agent to pull the thicker glue into the sawdust.

Sawdust and woodglue will work but you might not like what it looks like. Dont know what you plan to do, ie sand/finish in some way etc. Do a test if possible to see if you like it.

I use microballoons to extend the fill capacity of epoxy, using it on the first and or second pour, so the final is pure epoxy.

Have your say...
