Is it okay to use coarse grit sandpaper for lapping stones?

Mesh drywall sandpaper would be a even better choice.

You're talking about that 3m sanding screen right?

Sandpaper is great, but it can shed abrasive which can get lodged in your stone. Make sure to check the stone for this when you are done.

I've lapped stones on concrete, cinder blocks, against other stones, with sandpaper, silicon carbide powder on a lapping plate and about any other way you can think of. Never once did I get abrasive lodged in the stone.

How coarse are we talking? I wouldn't go using no 36 grit sandpaper to flatten a stone.....it'll leave to big of gouges in the stone.
I'd use something like 120 as the coarsest.

Lets say 200 grit

Yes, that's fine.
