• Best For: Tile and grout contractors who want solvent-style protection in a water-based sealer for grout, quarry tile or Saltillo.

• Expert Note: Because it is vapor permeable, it protects grout and porous tile without trapping moisture vapor underneath; this item is the 1 gallon size, 1680-2112.
