Miracle Sealants 511 Impregnator is a professional-grade, oil-based polymerized-silicone penetrating sealer for medium- to dense-porosity tile, stone, concrete, masonry and grout. It soaks into the surface and forms an invisible barrier that resists water, alkalis, staining, salt-ion intrusion and freeze/thaw damage while still letting moisture vapor escape. It is not a surface coating and will not alter the natural look; treated surfaces are harder and less slippery. It is UV-transparent, resists acid rain, will not yellow, and meets USDA requirements for incidental food contact. Note: 511 Impregnator will not stop acid etching.
