Miracle Sealants 511 Porous Plus Sealer

Protect highly porous stone surfaces from moisture and stains without changing their natural appearance.

Looking for a Sealer Designed for Extremely Porous Stone?

Miracle Sealants 511 Porous Plus is a professional-grade penetrating sealer specifically formulated for the protection of highly porous natural stone, masonry, and grout. Engineered to penetrate deep below the surface, it creates an invisible barrier that helps resist moisture, water penetration, and common staining agents while allowing the substrate to breathe naturally.

Unlike topical coatings, 511 Porous Plus preserves the natural beauty of the material by leaving no surface film or gloss. Treated surfaces maintain their original appearance while becoming more resistant to staining, easier to maintain, and safer underfoot with improved surface hardness and reduced slipperiness.

Whether you're sealing natural stone countertops, porous tile, masonry, or grout, Miracle 511 Porous Plus delivers long-lasting professional protection without altering the look of the surface.

Why Choose Miracle 511 Porous Plus?

Highly porous stone materials require deeper protection than standard sealers can provide. Miracle 511 Porous Plus is chemically engineered to penetrate deeply into absorbent surfaces, creating long-lasting stain and moisture resistance while allowing the stone to continue breathing naturally.

Because it does not form a surface coating, the sealer preserves the original texture, color, and finish of the stone without creating unwanted gloss or buildup. This makes it an excellent choice for premium natural stone installations where maintaining the authentic appearance is just as important as protecting the investment.

Whether you're sealing newly installed stone or protecting existing surfaces, Miracle 511 Porous Plus provides the professional-grade performance trusted by fabricators, installers, and restoration specialists.
