Hybrid Sealant for Waterproofing GoBoard Installations GoBoard® Pro Sealant is a one-component, moisture-curing hybrid joint sealant designed to waterproof and bond GoBoard panels, seams, joints, and fastener penetrations. Its 100% solids formula creates durable, waterproof seals while adhering to a wide range of common construction materials. Reliable Adhesion Across Multiple Building Materials The sealant bonds to GoBoard, metal, plastic, concrete, wood, foam, and ceramic surfaces, making it suitable for both new installations and repair work. Its no-sag consistency allows for clean application on vertical and horizontal surfaces using a standard caulk gun. Flexible Performance for Interior and Exterior Applications After curing, GoBoard Pro Sealant accommodates up to 25% joint movement while maintaining a waterproof seal. The sealant skins in approximately 15 minutes, withstands temperatures up to 250°F, and is approved for both interior and exterior installations, including wet areas.
