Thank you Square Eye, given that I can't tear it out, do you think I can grind through until I have a smooth surface? What do you think that would take?
I need some help. While doing an exp. Agg. patio on a hot day, the concrete set faster than I could get all the stone embedded. The result is a shabby-looking slab surface with some stone embedded, some areas just pitted, where the stone made an impression. I'm considering a surface grinder...
