DAP 10.1 oz. Dynaflex Ultra White Advanced Exterior Sealant

DAP Dynaflex Ultra Advanced Exterior Sealant is powered by innovative Weather Max technology for long-lasting, all-weather exterior protection. Engineered for windows, doors, siding, and trim, it provides exceptional UV resistance against fading, yellowing, cracking, chalking, and crumbling to keep joints looking new over time. Once cured, this sealant resists mold, mildew, and algae while remaining permanently flexible to endure expansion and contraction caused by extreme temperature fluctuations and weather. Featuring strong multi-material adhesion, it tools smoothly, cleans up easily with water, and is rain and paint ready in one hour for maximum productivity.
