DAP Silicone Rubber Sealant is a 100% silicone, one-component sealant designed for professional and DIY sealing applications on windows, doors, siding and other interior and exterior surfaces. This waterproof, flexible sealant creates a durable barrier that protects against moisture infiltration while accommodating the movement and vibration that occurs in buildings and structures over time.
Whether you’re sealing gaps around window frames, door jambs, siding joints or other areas where air and water infiltration could cause damage, this aluminum-colored sealant provides a reliable, long-lasting seal. The silicone formulation resists cracking, crumbling, chalking and shrinkage even when exposed to temperature extremes and environmental stress, making it an ideal choice for exposed outdoor applications as well as interior use.
