Miracle Sealants Grout Release Sealer for Tile & Stone

Grout Release is applied to tile or stone before grouting. Its polymerized silicone formula penetrates the surface and forms an invisible barrier that helps prevent grout and mortar residue from sticking or causing stains, making the haze-removal and cleanup process easier after the grout has been placed.

The manufacturer identifies Grout Release for cement, epoxy, urethane, new-generation grouts, and mortars. Because these materials can leave residue or stain certain surfaces during installation, the release barrier is designed to reduce direct adhesion before grouting begins and make subsequent cleanup more manageable.

Compatible surfaces include quarry, glazed, ceramic, and porcelain tile; marble, granite, travertine, slate, and quartz; plus brick, terrazzo, and grout. It is intended for interior and exterior projects such as kitchens, restrooms, showers, patios, and driveways, subject to successful testing on the specific substrate.

No. Grout Release penetrates rather than creating a topical coating and is designed not to alter the material's natural appearance. The barrier remains vapor permeable, UV transparent, and non-yellowing while providing resistance to stains, water, weather, acids, salts, and freeze/thaw exposure.

Use Grout Release undiluted on a clean surface before grouting, allow three to five minutes for penetration, and remove all excess with a clean, dry cloth. Allow six to 12 hours before grouting. For optimum results, keep the treated area dry and free from staining materials for 72 hours.

One quart covers approximately 125 to 1,000 square feet. Actual coverage depends heavily on the substrate's density, porosity, texture, absorption, weather exposure, dwell time, and application method, so porous materials will generally require more product than dense, low-absorption surfaces.

Grout Release provides a stain-resistant, water-resistant barrier, but Miracle Sealants positions it specifically as a pre-grouting treatment. Whether a separate penetrating sealer is needed afterward depends on the tile, stone, grout, and project requirements, so follow the applicable manufacturer specifications for final protection.

The formula contains combustible petroleum distillates and must be used with continuous ventilation. Keep it away from heat and open flames, wear chemical-resistant gloves, avoid prolonged skin contact, and keep children and pets away until dry. Store the original container sealed near 77°F; the listed shelf life is 12 months.
