Is there any grout left in the joints-why grind-what is the issue-probably bad lippage I would guess.
Cant just hone and run.

Hello partners,
 
    I wanted to get your opinions on grinding and honing on a limestone floor that the sub-structure is wire lath on top of plywood. The limestone is chipping because of defection on the floor. The sub-structure was not reinforced properly before the installation of the limestone. This limestone is very porous and I worry that when grinding and honing, the limestone will absorb the water into the plywood, and cause problems such as warping. Anyone ever have any problems with this? I know to keep the water to a minimum, but its limestone, its like honing a sponge.
