About This Product
Penetrating Stone Sealer for Water and Stain Protection
Miracle Sealants® 511 Impregnator is an oil-based penetrating sealer designed for medium to dense porous natural stone, tile, grout, concrete, and masonry. Its polymerized silicone formula penetrates below the surface to resist water, stains, alkalis, salt intrusion, and freeze/thaw damage, helping protect valuable installations from everyday use and exposure.
Invisible Impregnator Protection Without a Surface Coating
This impregnator forms an invisible barrier instead of leaving a topical film. Moisture vapor can still escape through the treated material, while the UV-transparent, non-yellowing protection retains the natural character of the surface. Because the oil-based formula may shade some materials, appearance testing is important before treating the full area.
Interior and Exterior Tile Sealer for Heavy-Use Areas
511 Impregnator is suitable for compatible marble, granite, travertine, quartz, slate, ceramic and porcelain tile, cement grout, brick, concrete, terrazzo, and stucco. It serves kitchens, bathrooms, showers, patios, pool decks, countertops, restaurants, hotels, and retail spaces where durable moisture, stain, weather, and slip-resistant protection is needed.

Common Questions
Frequently Asked Questions
What surfaces can Miracle Sealants 511 Impregnator be used on?
The manufacturer identifies medium to dense porous tile, stone, concrete, masonry, and grout as the intended surface types. Listed substrates include quarry, ceramic, porcelain, glazed, and concrete tile; marble, granite, travertine, quartz, and slate; cement grout; brick, concrete, terrazzo, and stucco.
How does 511 Impregnator protect the surface?
The polymerized silicone formula penetrates into the substrate and forms an invisible barrier that resists moisture and stains. It does not create a topical surface coating, and moisture vapor can continue escaping through the treated material. The manufacturer also states that treated surfaces become harder and less slippery.
Will 511 Impregnator change the surface's appearance?
511 Impregnator is designed not to alter the natural look of the surface, but the manufacturer notes that its oil-based formula may shade some materials. Complete several inconspicuous test patches before treating the full area to confirm appearance, absorption, and product suitability.
What does 511 Impregnator protect against?
It provides resistance to water, stains, alkalis, salt-ion intrusion, weather, acid rain, and freeze/thaw damage. However, 511 Impregnator will not stop acid etching on acid-sensitive stone. Sealing can reduce absorption and staining without preventing the chemical surface damage caused by acidic substances.
Can 511 Impregnator be used indoors and outdoors?
Yes. The sealer is intended for interior and exterior heavy-use residential and commercial areas. Manufacturer-listed applications include countertops, floors, kitchens, bathrooms, showers, patios, walkways, pool decks, restaurants, hotels, grocery stores, retail spaces, locker rooms, stadiums, and other public work areas.
Can 511 Impregnator be used in food preparation areas?
The technical data sheet states that 511 Impregnator meets USDA requirements for incidental food contact. This designation applies when the product is used and cured according to the current label. It does not replace routine cleaning, sanitation, or other requirements for surfaces used around food.
How much area does 511 Impregnator cover?
Coverage ranges from approximately 500 to 4,000 square feet per gallon and varies with substrate texture and porosity. The consumer product page lists pint, quart, and gallon sizes. More absorbent or textured materials generally provide coverage near the lower end of the range.
Is 511 Impregnator water-based, and how long does it take to cure?
No. 511 Impregnator is an oil-based formula containing mineral spirits, not a water-based impregnator. It is supplied ready to use and must not be thinned or diluted. The product becomes dry to the touch in approximately 1 to 3 hours and reaches full cure in 72 hours. Follow the label's ventilation and safety requirements.
