Hello guys

Hey I am working on a sand stone patio area with hard water stains.

I am blasting the floor with glass beads and it still looks like it has some light white haze to the sand stone.

This is even after I wash the floor with water and dry the floor. Look good when wet.

Home owner wants it sealed with a natural seal no enhancing sealer.

Will the floor look better if use a 80 grit floor brush? To remove some of the stone and expose new stone?

Has any one had a problem like this?

I blasted the same floor 4 years ago came clean and looked good.

Looking for help.
