Prochem Stone Seal R603 is a professional-grade, water-based impregnating sealer formulated to protect porous stone and masonry surfaces such as terracotta, limestone, sandstone, travertine, slate, brick, concrete, and grout.

Enhanced with advanced fluoropolymer technology, it delivers long-lasting, invisible protection against oil- and water-based staining without altering the natural appearance, texture, or colour of the material. The clear, low-odour solution penetrates deeply to create a breathable barrier that repels moisture and dirt, helping to maintain a cleaner, more durable surface over time.

Ready to use straight from the container, it can be easily applied with a brush, roller, or mop and typically dries within two hours, with full curing achieved in 72 hours. Ideal for both interior and exterior use (following a patch test), Stone Seal R603 is also pH-neutral, making it safe for most natural stones and tiled surfaces.

Each 5-litre container covers approximately 150–200 m² depending on the porosity of the surface, and it is best maintained with a neutral cleaner to preserve the seal’s effectiveness.
