POURTHANE NS is a one-component, moisture-curing, non-sag polyurethane joint sealant designed for vertical and overhead applications. It provides strong adhesion to a wide range of construction materials—including concrete, masonry, aluminum, and PVC—without the need for primer in most cases.

This ready-to-use, low-VOC sealant offers ±35% joint movement capability, excellent weather and UV resistance, and long-term elasticity for both civil and industrial projects. POURTHANE NS is ideal for sealing joints in precast panels, façades, and roof tiles, delivering a durable, flexible, and professional-grade finish that meets ASTM C920 and USDA compliance standards.
