About This Product
Penetrating Grout Sealer for Cementitious Joints
Miracle Sealants® Grout Sealer is a penetrating sealer designed to protect sanded and unsanded cementitious grout and mortar joints from moisture and common stains. It gives tile installations practical protection in areas exposed to splashes, spills, dirt, and changing weather, helping preserve grout in kitchens, bathrooms, showers, floors, and exterior applications.
Invisible, Breathable Grout Protection
The formula penetrates the joint and forms an invisible barrier instead of leaving a topical coating. This approach allows moisture vapor to escape while maintaining the grout's natural look. A built-in applicator tip directs the sealer along the joint, giving homeowners and professionals a controlled way to protect grout without coating the surrounding tile or stone.
Weather-Resistant Performance Indoors and Outdoors
Designed for interior and exterior use, the cured treatment is weather resistant, freeze/thaw resistant, salt water resistant, acid resistant, and UV transparent. It will not yellow, making it a dependable choice for kitchen counters and floors, bathroom showers and floors, service porches, and other compatible grout or mortar installations.

Common Questions
Frequently Asked Questions
What surfaces is Miracle Sealants Grout Sealer designed to protect?
Miracle Sealants Grout Sealer is designed for sanded and unsanded cementitious grout joints and mortar joints. It protects the joints within tile and stone installations, but it is not presented as a general-purpose tile sealer or stone sealer for treating the entire surrounding surface.
How does Miracle Sealants Grout Sealer work?
The sealer penetrates the grout or mortar and forms an invisible barrier that resists moisture and common stains. Because it is not a topical coating, it allows vapor to escape and is designed to preserve the joint's natural appearance rather than leaving a visible film.
Can Miracle Sealants Grout Sealer be used indoors and outdoors?
Yes. The manufacturer approves Grout Sealer for interior and exterior applications, including kitchen counters, kitchen floors, bathroom showers, bathroom floors, and service porches. Its focused applicator tip makes it suitable for protecting grout lines in both new installations and properly prepared existing joints.
Does this grout sealer resist weather and UV exposure?
The cured treatment is weather resistant, freeze/thaw resistant, salt water resistant, acid resistant, and UV transparent. The manufacturer also states that it will not yellow, making it suitable for exposed exterior grout as well as moisture-prone interior installations when applied according to the product directions.
Can Grout Sealer be applied to new and existing grout?
New grout or mortar must cure according to its manufacturer's specifications before sealing. Existing joints must be dry and free of old sealers, dirt, hard water deposits, efflorescence, rust, and grime. Apply through the applicator tip and wipe excess from adjacent tile or stone before it dries.
How much grout does one 6 oz bottle cover?
The manufacturer lists coverage of 25 to 75 linear feet of grout per 6 oz bottle. Its product data sheet also estimates approximately 60 to 115 square feet, with actual coverage affected by density, porosity, texture, absorption, weather, dwell time, and application method.
How long does Miracle Sealants Grout Sealer take to dry?
Grout Sealer becomes dry to the touch in approximately one to three hours and may then be placed into service. For optimal results, the manufacturer directs users to keep the treated area dry and free from staining materials for 72 hours after application.
Should the sealer be tested before full application?
Yes. Because materials can respond differently, the manufacturer recommends testing several inconspicuous areas before full application. Protect neighboring wood, carpet, metal, landscaping, and other non-masonry surfaces, remove any sealer that reaches tile or stone before it dries, and use the product in a well-ventilated area.
