Depends on how rough it is. Try coarse sandpaper (60 grit) to get it mostly smooth, and then try something like 120 grit to get it a little smoother. The 60 grit won't clog up so bad. You can pour envirotex epoxy pretty thick (I've seen people go as thick as 1/4"-1/2" in multiple pours), so It can cover up a surface that is somewhat rough.
