About This Product

Grout Shield Additive with Built-In Stain Protection

Miracle Sealants® Grout Shield is a specialty grout sealer additive that replaces mixing water in compatible cement-based grout to create stain protection throughout each joint. Because protection is incorporated while the grout is mixed, installers can avoid waiting for cured grout before completing a separate sealing application, helping reduce labor and streamline the installation.

More Consistent Grout Strength and Color

By removing inconsistent tap water from the primary mix, Grout Shield helps create more uniform, durable grout with improved color quality. The additive also increases compressive and tensile strength, giving contractors and DIY installers a practical way to improve both appearance and performance without introducing a separate post-grouting product.

Interior and Exterior Protection Backed by Warranty

Grout Shield is suitable for interior and exterior projects using compatible sanded or non-sanded cement grout. Once installed according to manufacturer instructions, the finished grout resists staining and is backed by a limited lifetime warranty, providing long-term confidence across indoor and outdoor tile installations.

Common Questions

Frequently Asked Questions

How does Miracle Sealants Grout Shield work?

Grout Shield is a liquid sealer additive mixed into compatible cement-based grout instead of ordinary mixing water. The protection is distributed throughout the grout as it is mixed, creating stain-resistant joints without waiting for the installed grout to cure before applying a separate grout sealer.

What grout types are compatible with Grout Shield?

Grout Shield can be used with compatible cement-based sanded and non-sanded grout. Do not use it with epoxy grout, liquid or ready-to-use grout, grout that already claims stain resistance, latex additive, or any other additive. It is also not recommended where chemical resistance is required.

How much grout does the 70 oz Grout Shield container support?

The 70 oz container is matched to one 25 lb bag of sanded cement-based grout. Other package combinations use different amounts, including 24 oz for a 7 lb box of sanded grout and 48 oz for a 10 lb bag of non-sanded grout, so select the container for the grout package.

Does Grout Shield completely replace mixing water?

Grout Shield replaces the primary mixing water, but the exact liquid requirement depends on the grout package and desired consistency. After the recommended additive amount has been used, the manufacturer allows clean, cool water to be added in increments of up to two ounces until the desired consistency is reached.

Does grout mixed with Grout Shield need to be sealed afterward?

No additional sealer is needed for grout made with Grout Shield according to the manufacturer's specifications. If the tile or stone itself requires sealing, apply a compatible Miracle Sealants penetrating sealer before grouting and avoid coating the tile or stone edges, which could interfere with grout bonding.

What benefits does Grout Shield provide beyond stain resistance?

Grout Shield adds compressive and tensile strength and helps produce consistent, durable grout with improved color quality by removing inconsistent tap water from the primary mix. The additive is suitable for both interior and exterior installations when used with a compatible cement-based grout.

How long should an installation made with Grout Shield be protected?

Protect the finished installation from traffic and impact for at least 24 hours. Keep it away from water immersion or freezing for 10 days, or for the grout manufacturer's longer specified period. Wait at least 10 days before routine cleaning, use appropriate pH-neutral cleaners, and clean spills promptly.

What does the limited lifetime warranty cover?

The limited lifetime warranty applies to the original owner and covers the Grout Shield product when installed according to Miracle Sealants specifications, industry standards, and building codes. Store unopened product in a cool, dry location away from direct sunlight, never use frozen material, and wear safety glasses and chemical-resistant gloves while handling it.
