X-Shield StainBlock Sealer is a high-performance, water-dispersed fluorosurfactant sealer designed to create a durable, invisible barrier that resists both oil and water-based stains. It penetrates deeply into porous substrates such as concrete, brick, natural stone, unglazed tile, and grout — providing long-lasting protection without altering the natural appearance of the surface. The non-film-forming formula allows the surface to breathe while delivering excellent hydrophobic and oleophobic performance, making it ideal for indoor and outdoor applications.
