Remove peeling paint?

So, this is a flooring question - but not in the house. It's in my garage. It looks like the previous owner did a DIY "paint the garage floor kit" and probably used it improperly. Since I moved in 1.5 years ago, the floor has been peeling. It's getting worse. There are chips/flecks of paint that get dragged into the house on shoes, the floors of our cars are getting full of them, and it just generally looks super ugly.

What is the best way to remedy this? I'm pretty-sure I can't paint over it, as the new paint will just bond to the old paint and flake off with it. I don't want to pressure wash it all off (A. everything would get soaked + walls are finished; B. It's winter). Would a floor sander type of method work out, or would the concrete just chew up sanding discs?

I am fine with the floor just being concrete - it doesn't HAVE to be repainted, but if it looks bad after removing the old stuff, I'd probably want to put down new paint.

Info: House/Garage was built in 2002, Chicago climate, ~750sqft garage floor.

It looks like Sunbelt rents them for $420/day (or $865/week). It is an 8" electric shot blaster and says it can do 275 sqft/hr. I would assume that means if you know what you are doing. That does not include the dust collector at $97/day (or $290/week). So it's looking like $517 for a day, or $1,155 for a week - plus media. If I could find 2 other people (neighbors, etc) that wanted to go in together for a week, that might be affordable. +$500 to DIY seems a bit much - I guess I need to find a quoted price to compare.

Yeah, I haven't had any luck either. Nobody seems to care about garage floors :(

I'll look into your other suggestion and see what I find. The cost of renting the shot blaster doesn't put it out of the question, but it does make me want to explore other avenues before committing. Thanks again for all your help.


EDIT:
Looks like $97/day for the grinder, and $97/day for the dust collection vac. $194 is much easier to swallow, thus far.
