The DAP INC 8728 is a 100% silicone acetoxy-cure caulk formulated for window and door sealing applications in both residential and light commercial settings. It delivers a flexible, watertight seal that holds up against temperature swings, moisture, and UV exposure over the long term. The 9.8 oz cartridge is compatible with standard caulk guns and is designed for professional applicators who need a reliable perimeter seal around window frames, door casings, and similar penetrations. Note that this product is not paintable, so surface prep and color selection should be confirmed before application.
This caulk suits interior and exterior sealing tasks where a durable, moisture-resistant bond is the priority. Common applications include sealing window and door frames to exterior cladding, filling gaps at sills and jambs, and waterproofing penetrations subject to direct water exposure. It performs in a wide range of climates and is appropriate for both new construction and maintenance repair work.
Designed as a direct-apply sealant for window and door perimeter sealing on residential and light commercial structures. Suitable for most common substrate types encountered in window and door framing applications.
Application should be performed by a qualified tradesperson or knowledgeable installer familiar with sealant work. Surfaces must be clean, dry, and free of old caulk, dust, and oils before applying. Load the cartridge into a standard caulk gun, cut the nozzle tip at a consistent angle, and apply in a steady bead. Because this product is not paintable, confirm color match before sealing final surfaces.
