Hi Carl I would think sand paper open face type abrasive for removing the most stock but be careful  you don’t make a dip in the patch 120 grit.

I am doing a large Terrazzo restoration with a lot of patch work 4"x4" 3" round holes etc. who has found the fastest/best way to take down/flatten the initial patch after it sets up.

Thank Carl
