This looks like an acid burn on the slate, I had a similar job like this in Miami that no other contractor could fix, we went down there and used and alkaline cleaner scrubbed the slate and then used 250 grit black honing powders and then used the Color Enhancer form StoneCare Central and the job turned out great.


Recommend you test an area to see if you get  the same results.
