My garage was converted to a living space. The house is a typical San Francisco home, the garage makes up the whole ground floor. I took out the carpet, the plastic sheets underneath and I am left with a black coated cement floor. My neighbor believes this to be asphalt emulsion. I, for the life of me, cannot remove this stuff.
I prefer to have a nice clean cement floor. I've used all kinds of chemicals, scrapers, sanders but it just muddies up my tools without actually coming off. How can I resolve this??
I'm reluctant to use a sand blaster and a floor grinder, as they are both expensive to rent out here. If it's not feasible to remove this coating, can I just paint over this stuff with concrete paint?
