Control methods and work practices that reduce dust accumulation in concrete cutting and grinding include: Wet Cutting (Water Spraying) – This engineering control helps to eliminate silica dust from ever becoming airborne and is the most efficient method of dust control in concrete cutting and grinding.
Keeping this in view, can you grind concrete down 1 2?
A small planetary concrete grinder with basic grinding tools will remove around 1/16” of the concrete in 1-2 passes in a normal situation.

What do I use to sand concrete?
For basic sanding, use sandpaper with the grit between 40-60. To remove minor irregularities, use 80-120 grit sandpaper. For perfect finish and smoothness, use superfine sandpaper with grit ranging between 200-400. If there are severe imperfections, then you need to use a floor grinder or special diamond disc.
