Dap Dynaflex 230 is a premium latex sealant engineered for both interior and exterior applications. This advanced formulation combines a silicone-tough latex with exceptional flexibility and durability, making it ideal for sealing gaps and cracks around your home. Whether you're protecting windows, doors, siding, trim, molding, or baseboards, this sealant provides a permanently flexible, crack-proof seal that moves with the natural expansion and contraction of building materials without compromising its integrity.
