About WL500 – Last Chance.
WL500 was developed as an alternative to replacing stone with existing erosion issues and for soft friable or crumbling stone. WL500 is a penetrating, acrylic complex that forms a high-performance, seamless polymer matrix over the surface that powerfully adheres to the substrate resisting pressure from erosion and hydrostatic pressures beneath it. On the surface the barrier acts like a one- piece sheathing that protects the substrate below it from additional surface salt water entry while providing an attractive gloss wet look. Below it, the barrier, an engineered polymer of acrylic resins and other proprietary additives, anchors to the substrate holding the substrate in place while resisting erosion effects that may continue to develop from existing salt deposits.
