About Natural Seal Plus WB
WPN-250 Natural Seal Plus Water-Based is a highly advanced, waterborne silica-based sealer engineered to provide superior protection for natural stone surfaces. Its dual-action system creates both a micro-engineered surface coating and a deep-penetrating sub-surface barrier, resulting in powerful stain resistance, water repellency, and long-term durability.
Designed for use on patios, pool decks, coping, walkways, and interior floors, WPN-250 resists red clay stains, oils, wine, acidic pollutants, and even permanent marker ink, making it ideal for both residential and commercial high-traffic areas. The innovative self-cleaning surface repels dirt, leaves, and debris, while its UV stability and low VOC content ensure lasting performance without altering the stone’s appearance. Easy to apply by sprayer or roller, it dries quickly, cures in 48 hours, and leaves only a slight enhancement to certain stone types.
