Limitations:
May darken or enhance some surfaces. Will not prevent water penetration through structural cracks, defects, or open joints. Not suitable for asphalt or other non-masonry materials. Not appropriate for use on limestone, marble, travertine, other calcareous stones, or non-concrete surfaces.
Application:
Apply once using enough material to keep the surface wet approximately 30 to 60 seconds before penetrating.
