Osi 1256965 H2u Window, Door, Siding & Trim Sealant, Clear, 10 Oz.

OSI H2U is a high-performance acrylic urethane sealant designed for window, door, siding, and trim applications both indoors and outdoors. This water-based formula combines superior adhesion, flexibility, and durability to seal joints and gaps where air and moisture infiltration are concerns.

The clear color makes this sealant ideal when you want a discreet, nearly invisible seal that blends with most surfaces. Its low-gassing formula is especially suitable for indoor projects where air quality matters. Once cured, the sealant dries to a glossy sheen, is fully paintable, and resists surface mold and mildew growth—extending the life of the sealed joint and reducing maintenance over time.
