The DAP 37009131 is a paintable latex sealant formulated for both interior and exterior applications. Dynaflex 230 delivers a flexible, weather-resistant seal that resists cracking and shrinking over time. Available in a 5.5 oz cartridge, it is suited for sealing gaps and joints around windows, doors, trim, siding, baseboards, and other building envelope penetrations. HVAC technicians, plumbers, and general contractors reach for this sealant when a durable, all-purpose acoustic and weather seal is needed on residential and light commercial jobs. It applies smoothly from a standard caulk gun and cleans up with water before cure.
Dynaflex 230 is designed for use on a wide range of substrates common in trade work, including wood, drywall, masonry, vinyl, aluminum, and painted surfaces. It performs reliably in indoor environments such as around pipe penetrations through walls or floors, and outdoors around window frames, siding joints, and exterior trim. The sealant remains flexible after cure, accommodating normal building movement without cracking. It is appropriate for residential new construction, remodeling, and service work where a single sealant needs to handle both interior and exterior conditions.
Designed as a general-purpose OEM-style replacement sealant for residential and light commercial interior and exterior sealing applications across a broad range of substrates.
Cut the cartridge tip at a 45-degree angle sized to the joint width and load into a standard caulk gun. Surface must be clean, dry, and free of dust or loose material before application. Tool the bead immediately after application for best adhesion. Clean up uncured sealant with water and a damp cloth; cured material requires mechanical removal.
