Problem isn't so much getting the paint off concrete, it's getting it OUT of concrete. Concrete is very porous. If it is pretty well cured, I would probably use a angle grinder with a knotted wire cup brush. Will likely leave some marks in the concrete though. __________________ John Schaben "Where all think alike, no one is thinking very much" To view links or images in signatures your post count must be 10 or greater.
