Grinding concrete is a very dirty job. If I had to do it I would use a 9 or 4 1/2 inch grinder with a concrete grinding wheel. At least an N95 dust mask, goggles, preferably like motorcycle riders use with the around the edges to keep dust out.

Show activity on this post. If it's a small area around the drain, the lowest cost, least-fuss option is one of these grinding blocks (use with some water and you can mop the slurry up rather than deal with dust in the air. Plug the floor drain first.) The one with the grooves is most applicable. Share.
