Black Diamond Stoneworks Natural Stone and Grout Penetrating Shower Sealer – 1 Quart

Protect natural stone and grout with a penetrating shower sealer

Black Diamond Stoneworks Natural Stone and Grout Penetrating Shower Sealer is a water-based solution designed to shield marble, granite, travertine, and limestone surfaces, as well as grout in tile, ceramic, and porcelain. By penetrating the surface, it creates a barrier that helps resist water, soap scum, and mineral buildup.

Across real bathrooms, this sealer preserves the original color, texture, and subtle veining that make natural stone unique. You will notice that surfaces retain their character rather than developing a dull, etched look over time, while the seal helps maintain a cleaner appearance between cleanings.
