18304 Dynaflex 230 Latex Sealant, Clear, 10.1 Oz

DAP Dynaflex 230 is a premium latex sealant with a silicone-tough formulation engineered for outstanding performance on interior and exterior applications. This flexible, crackproof sealant fills gaps and cracks around windows, doors, siding, trim, molding and baseboards, creating a durable seal that prevents water infiltration and air leaks while improving energy efficiency. The clear color blends seamlessly into your home's surfaces for an unobtrusive, professional appearance.

Dynaflex 230 endures the constant expansion and contraction caused by temperature changes and building movement without cracking or losing its seal. Once cured, the sealant resists mold and mildew growth, protecting both the seal and surrounding surfaces from moisture damage. The paintable formulation can be painted to match your décor, and cleanup is simple using just soap and water.
