The PS/PG-040P25X8H is a two-component, pourable, self-leveling polysulphide-based joint sealant engineered for horizontal construction joints requiring durable, watertight sealing. This ambient-temperature-curing system forms a tough, flexible rubber seal with excellent adhesion to concrete, stone, metals, aluminum, glass, and wood. It accommodates moderate joint movement while maintaining chemical and UV resistance in exposed environments, including full submersion after cure and potable water applications.
