I am planning on gluing up some picture frames with West epoxy with wood

How well does the squeeze out sand?

I would just test it, but mixing up a small batch is a bit of a chore; so I
am hoping someone knows from experience. Thanks

It tends to clog sand paper rather fast. You'll use of lot of paper.
There comes a point where the epoxy is no longer sticky but is still fairly
soft. At this point it is easy enough to cut and peel using sharp tools.
