Problem with sawdust paste

[brianhabby]

Hi there

I've read several times that you can mix sawdust with some PVA glue to make a paste to use as a filler in open joints etc.

I tried this but the stuff had dried very dark and really shows up on the wood. Is this normal? and if not, what might I be doing wrong?

I would have thought it should dry the same colour as the wood since the PVA dries clear :?

I'm using it on oak if that matters.

regards

Brian

Could the water in the PVA have stained the oak?

Hi Smudger

The PVA I've used is from the same bottle that I used to glue up the project and there is no indication of darkening anywhere else.
