DAP DYNAFLEX 230 Premium Elastomeric Sealant in Clear provides a flexible, waterproof and weatherproof seal around windows, doors, siding, trim and baseboards. Its advanced acrylic latex formula handles expansion and contraction caused by changing temperature and humidity, helping joints stay sealed without cracking. It adheres to many common building materials, including painted and unpainted wood, aluminum, vinyl, glass, drywall, masonry, fiber cement, composite trim and PVC trimboard, for interior and exterior projects.
The 10.1 fl. oz. cartridge fits a standard caulking gun for controlled application along longer seams and around multiple openings. One cartridge covers approximately 55 linear feet with a 3/16-inch bead. The low-odor formula tools smoothly and cleans up with water while wet. Cured sealant resists mold and mildew and meets ASTM C920, Class 25.
Clear formula: This sealant applies white and dries clear in approximately 7–14 days, depending on joint depth, temperature and humidity. Allow it to dry completely clear before applying latex or oil-based paint. Water exposure is permitted after approximately 24 hours. Apply to clean, dry, structurally sound surfaces between 40°F and 100°F, and protect from rain and freezing temperatures for the first 24 hours. Suitable for joints up to 2 inches wide and 1/2 inch deep; use backer rod for deeper gaps. Not intended for continuous underwater use or filling surface defects. Coverage and drying time vary with application conditions.
