Best way to remove paint from cinder block wall

I'm remodeling a room in my basement and I found the cinder block walls had been painted with the first coat being a mildew resistant finish, and then the second, outer coat was Dry-lok waterproofing, so they painted the two types on the walls in the wrong order. (I found this out thanks to someone on here explaining to me why the Dry-lok was peeling off in large chunks :thumbsup: )

I am using a grinder with a coarse knotted cup brush to remove both layers of paint and it works, but it's eating up the brushes quickly and it's taking foreeeevveeerrr to finish the job. Is there a faster way?
