Looking for some advice re: the cleaning and sealing of brick flooring. Previous owners turned a breezeway into a mudroom. We blew out the wall and incorporated this room into the kitchen as a dining area. How do we go about sealing this floor from the inevitable food/beverage spills? Will need to be cleaned first - with acid? These bricks are beautiful, a lot of white in them - appear to be old, maybe taken from an old building or something as the house is only about 30 years old. Thanks in advance!
