CoverTec Satin Tile Grout Sealer – Clear Polyurethane Protection for Ceramic and Porcelain

This two-part water-based polyurethane system forms a durable satin film directly on dense ceramic and porcelain tile, providing surface-level protection that standard penetrating sealers cannot achieve on non-porous materials.

While impregnating products struggle to bond into glossy surfaces, this mixture anchors to both grout lines and glazed tile faces to block moisture, dirt stains, and daily foot traffic. Combine Part A and Part B to activate the formula, then spread a thin, even coat with a foam brush or microfiber applicator. Keep the layers light to prevent pooling in grout joints, allow complete curing per the manufacturer label, and delay water exposure until the protective skin fully sets.

Shower and Floor Performance Features

• Dense-Surface Compatibility: Engineered specifically for ceramic, porcelain, and glazed substrates where traditional seep-in sealers cannot absorb.
• Visible Satin Finish: Deposits a smooth coating that revitalizes faded grout tones while reducing liquid uptake for faster daily wiping.
• Water-Resistant Shield: Designed for wet environments like shower walls and bathroom floors, minimizing soap scum adherence and simplifying routine cleaning.

The compact 4 ounce volume functions as a dedicated test kit. Process a small patch on an unobtrusive area or leftover tile to verify bond strength and confirm the final sheen before scaling up to full room coverage. Thoroughly clean and degrease the installation, remove any prior waxes or sealants, and guarantee the surface is completely dry before mixing and applying the two components.
