This water-based silicone water repellent system is designed to provide exceptional protection for exterior building facades, including stone, brickwork, natural stone, and plaster. It penetrates deeply into the substrate to form a breathable, colorless, and waterproof barrier that protects against rain, carbon dioxide, and dust exposure while preserving the natural appearance of the surface. The system maintains the original substrate color, reduces dirt pick-up, and delivers long-lasting resistance to harsh weather conditions. It is easy to apply by brush, roller, or spray, ensuring uniform coverage and reliable, durable performance with an aesthetically clean finish.
