Dholpur(Sandstone) floor restoration

Below please find some before and after images of cleaning work done on Dholpur floors on a terrace. Usually, two grits numbering 60 and 100 are good enough to clean Dholpur. However, because of the green marble slabs in between the Dholpur slabs, we have run grit numbers 200 and 400 to give a honed finish to the green marble.
Once completely dry we have applied two coats of sealer, which was left to dry for 72 hours.
Thereafter a clean terrace was ready for us again!
