Miracle Sealants 511 Porous Plus is a premium penetrating sealer specially formulated for highly porous stone, tile, and grout surfaces. It delivers advanced protection against water, oils, stains, alkalis, salt ion intrusion, and freeze/thaw damage—all while preserving the material’s natural look and breathability. This breathable barrier does not form a surface coating, nor does it yellow, peel, or discolor over time. Its UV transparency and resistance to acid rain make it ideal for both interior and exterior applications in residential, commercial, and industrial environments. With coverage rates averaging two to ten times higher than typical sealers, it ensures lasting performance and cost efficiency. Suitable substrates include granite, marble, travertine, slate, limestone, sandstone, terra cotta, ceramic tile, grout, cantera, adoquin, and more. Whether protecting a kitchen countertop, pool deck, walkway, or bathroom floor, 511 Porous Plus provides long-lasting durability and invisible protection—though it will not prevent acid etching.
