HydroSweep Reactive Resin Joint Sand is a one-part, ready-to-use joint stabilization solution. Powered by a next-generation synthetic resin that hardens through air activation it is designed to create strong, durable, and permeable paver joints. Built for real-world conditions, it can be installed rain or shine and produces haze- and dust-free results for a clean, professional finish. HydroSweep forms hardened joints that resist erosion, withstand residential vehicular traffic, and perform through harsh freeze/thaw cycles. Ideal for walkways, patios, pool decks, residential driveways, and more, HydroSweep also performs reliably in environments exposed to chlorinated or salt-treated water and moderate de-icing products.
