Miracle Sealants 511 Impregnator Water-Based is a professional-grade penetrating sealer formulated to protect natural stone, tile, grout, and masonry surfaces where a water-based solution is preferred. It creates an invisible barrier that resists moisture, stains, and damage from water, alkalis, salt, and freezing conditions—offering strong protection with less odor than solvent-based alternatives. While it shields the surface, it still allows moisture vapor to escape, helping maintain the natural look and feel of the material.
