What is Waterproof Grout and Why is it Important for Showers?
Waterproof grout is a specialized type of grout formulated to resist water penetration, making it particularly important for wet environments such as showers. Unlike regular grout, waterproof grout incorporates additives that enhance its water-resistant properties, preventing mold and mildew growth while maintaining the integrity of tiles over time.
