You don't. You paint over it with deck paint (deck paint is designed for boat decks and is VERY thick and seals any surface.) Then you just lay your new floor over it once it dries. Open windows and have fans going while rolling it on.
use an electric grinder with a diamond/cuphead wheel, wet the concrete to avoid creating dust

you can get the wheels on ebay at a good price if you can't find them locally
I'm not sure how safe this is, but I think gasoline works.
