I have never done that
It will be a big mess-but do-able.
I think you have to be very mindful of the sanded mortar grout.
May want to consider using a hard bond metal diamond for the initial grinding cut then move to brushes or DIP's.
Stone glamour works well on bricks-

I would do a test with low grit metal diamonds or a low grit malish brush and convince him that taking some of the edges down is more economical and authentic looking than flattening the floor completely.

Everyone,

Happy New Year.  Home owner has 900 sq ft of this brick. He wants it flattened. (A lot of lippage). Anybody had any experience flattening this brick?  One concern is that it is only 1/2 inch thick. Whar are your thoughts?
